Safety Precautions

When handling replacement parts, 3Com recommends that you always use a wrist strap connected to a proper ground. This helps prevent the module from being damaged by electrostatic discharge. Additionally, when not in use, the module should be stored in an antistatic bag.

If the system is powered on when you are replacing a module, do not insert any metal objects, such as a screwdriver or a finger with jewelry, in the open slot. This could cause burns or other bodily harm, as well as system damage.

30 C HAPTER 4: I NSTALLING AND C ONNECTING C ORE B UILDER M ODULES

Vorsichtsmaßnahm en

Wenn Sie Ersatzteile handhaben, benutzen Sie immer ein Band am

Handgelenk, daß gut geerdet ist. Das hilft vermeiden, daß das Ersatzteil durch elektrostatische Entladung beschädigt wird. Darüber hinaus sollte ein Modul, wenn nicht benutzt, in einem antistatischen Beutel aufbewahrt werden.

Steht das System unter Strom, wenn sie ein Modul installieren oder auswechseln, führen Sie keine Metallgegenstände, wie einen

Schraubenzieher oder einen Finger mit Schmuck in den offenen Schlitz ein. Das könnte zu Verbrennungen oder anderen Körperschäden führen, sowie auch zu Schäden am System.

Mesures de sécurité

Lors de la manipulation des pièces de rechange, 3Com recommande de toujours utiliser une bande attachée au poignet et reliée à la terre. Cela aidera à éviter que la pièce ne soit endommagée par une décharge

électrostatique. De plus, lorsqu'il n'est pas utilisé, le module doit être conservé dans un emballage antistatique.

Si le système est alimenté lors de l'installation ou du remplacement d'un module, ne jamais insérer d'objet métallique tel qu'un tourne-vis ou un doigt portant un bijou dans la fente. Cela est susceptible de provoquer brûlures ou autres dommages corporels, et d'endommager le système.

Power Supply

Module

The CoreBuilder 7000 family ATM switch provides a dual load-sharing power supply capability where the second unit can serve as a redundant

power supply. For more information, see “Redundant Power Supply” on page 85.

For certain combinations of installed interface cards, the second power

supply cannot be used as a redundant supply (see “Providing Redundancy for Various Power Loads” on page 90).

This section discusses the following topics:

■

Installing a Power Supply Module

■

Replacing a Redundant Power Supply Module

Power Supply Module 31

Installing a Power

Supply Module

To install a power supply module:

1 Orient the module so that its sides enter the guides on either side of the chassis slot.

2 Slide the module into the chassis until the face panel is flush with the enclosure.

3 Secure the screws on either side of the front panel.

4 If a redundant power supply is not installed in the second power supply slot, cover the slot with a blank panel for safety.

Replacing a

Redundant Power

Supply Module

You can replace the redundant power supply without having to turn off the system (hot-swap). For more information on the operation of the

redundant power supply module, see “Redundant Power Supply” on page 85.

To replace a redundant power supply module:

1 Disconnect the power cord from the power supply.

2 Loosen the screws at the extreme right and left of the power supply, near

the handles (see Figure 3).

3 Grasp the handles of the redundant power supply you want to replace and pull them outward. This ejects the power supply.

4 Remove the new power supply from its antistatic bag. Place the old power supply in the antistatic bag and set it aside in a safe place.

5 Orient the power supply so its labelling is upright.

6 Insert the power supply into the chassis by placing it between the guides of the slot and sliding it until it stops.

7 Tighten the power supply’s securing screws.

8 Connect the power cord to the power supply.

To install a switch module in the CoreBuilder 7000 family ATM switch chassis:

1 Remove the new card from its antistatic bag.

2 Orient the card so its labelling is upright and make sure the inject handles are in the outward position.

Switch Module 33

3 Insert the card into the chassis by placing it between the guides of the selected slot and sliding the card until it stops.

4 Grab both inject handles and push them inward. This locks the card into the chassis. You may have to apply considerable pressure to the handles.

An audible “click” indicates that the connectors have engaged.

5 Tighten the card’s securing screws. You are now ready to connect cables to the appropriate ports.

Replacing a Switch

Module

To hot-swap the switch module:

1 Disconnect the cables from the card's ports. Ensure that there is a record of where the cables are attached so that you can correctly re-connect them to the new card.

2 Loosen the screws at the extreme right and left of the card, near the insert/eject handles.

3 Grasp the insert/eject handles of the card you want to replace and push them outward. This ejects the card. You may have to apply considerable force to the handles. You will hear a “click” to indicate that the connections have separated, and the card will slide slightly forward out of the CoreBuilder chassis.

4 Remove the new card from its antistatic bag. Place the old card in the antistatic bag and set it aside in a safe place.

5 Orient the card so its labelling is upright and make sure the inject handles are in the outward position.

6 Insert the card into the chassis by placing it between the guides of the selected slot and sliding the card until it stops.

7 Grab both inject handles and push them inward. This locks the card into the chassis. You may have to apply considerable pressure to the handles.

An audible “click” indicates that the connectors have engaged. Verify that the card has been properly installed by observing its LEDs.

8 Tighten the card’s securing screws.

9 Connect cables to the appropriate ports.

Setting up Switch

Module Redundancy

This section describes procedures for installing and setting up both a main and redundant switch module together.

Two different setup procedures are described. The first procedure covers setting up the main and redundant switch module hardware redundancy without setting up LANE redundancy. This procedure only requires operating the LMA. The second procedure sets up the main and redundant switch module hardware redundancy as well as LANE redundancy. It requires both the LMA and the Transcend Enterprise

Manager.

There are two situations where you would use the procedures of this section:

1 The initial installation of main and redundant cards.

2 The main card in the first slot has failed and the redundant card in the second slot has taken over as the main card. The failed card in the first slot has been replaced by a new card and this new card is now the redundant one.

Switch Module 35

Setting up Switch

Module Hardware

Redundancy

Use the following procedure to set up the switch module hardware redundancy.

1 Designate and mark the main and redundant switch modules.

2 Insert the switch module you marked as “redundant” in slot 2. Do not insert the switch module you marked as “main” yet.

3 Turn on the CoreBuilder 7000 family ATM switch.

The switch module in slot 2 becomes active.

Run the Integrated Fast Setup procedure (see “Integrated Fast Setup” on page 56.) using the LMA command

(9) FST

5 Insert the main switch module in slot 1.

6 Reboot the CoreBuilder 7000 family ATM switch using the LMA menu sequence:

(1) SYS / (7) RBO

The switch module in slot 1 becomes active.

7 Verify main and redundant switch module status using the LMA command:

(1) SYS / (4) SWM

You should see the following display.

Slot id Slot status Switch type Switch mode Memory size

------- ----------- ---------------- ------------ -----------

1 Occupied 16x16 ATM switch Active 8M

2 Occupied 16x16 ATM switch Redundant 8M

8 Run the Integrated Fast Setup procedure using the LMA command

(9) FST to verify the configuration in the main switch module.

The switch is now operational.

Setting up Hardware

Redundancy and

LANE Redundancy

This section presents a procedure for setting up both switch module hardware redundancy and LANE redundancy in the same session. Both the LMA and the Transcend Enterprise Manager are used.

36 C HAPTER 4: I NSTALLING AND C ONNECTING C ORE B UILDER M ODULES

General Description of the Procedure

The following is a general description of the procedure for orientation purposes only. When you perform the procedure, use the detailed steps in the following sections.

1 Install both switches in chassis and run CFGFRMAT.BAT on each one.

Connect Ethernet ports of each switch module and install at least one interface card in the chassis.

2 Configure the first switch using the Integrated Fast Setup of the LMA and do not reboot the switch in the Integrated Fast Setup.

3 Reboot the switch after one minute using the LMA menu.

4 Answer “no” to the prompt “Erase the setup parameters?” and use the

LMA to check that all configuration parameters (i.e., database, IP, NNI etc.) have passed successfully to the second switch module.

5 Configure LANE redundancy in the first switch using the Transcend

Backbone and Services Setup window and close the window when finished.

6 Reboot the switch after one minute

7 Configure LANE redundancy in the second switch module using the

Transcend Backbone and Services Setup window and close the window when finished.

8 After one minute use the MIB browser to check the LECS order list and the Backbone and Services Setup window to check the LECS database.

9 Reboot the box.

10 Check the second switch using the MIB browser to check the LECS order list and the Backbone and Services Setup window to check the LECS database.

Preparatory Steps

Carry out the following preparatory steps.

1 Install main and redundant switch modules in the switch module slot 1

and slot 2 respectively (see“Installing a Switch Module” on page 32). Do

not run the Integrated Fast Setup yet.

Each time the switch is rebooted during this procedure the cards change roles. The main card becomes the redundant card and vice versa. The main card can always be identified by its ACT LED flashing once every two seconds. The ACT LED of the redundant card flashes at a lower rate.

Switch Module 37

2 Verify that at least one interface card of any type is installed in the

CoreBuilder chassis in any interface card slots 3-6. Data is transferred between switch modules via a communications chip on an interface card.

3 Verify that the Ethernet management ports in both switches are connected to the NMS station. They can either be connected through a hub to the NMS station or through an Ethernet interface card in the same chassis, such as the CoreBuilder 7400 High Density Ethernet/ATM interface card, to the NMS station.

During the procedure you will need to verify connectivity between the

NMS station and the switch by pinging the switch module from the NMS station.

Connectivity between the switch module and its attached devices is established by a coldStart trap transmitted by the switch module when it boots. The coldStart trap causes a device to learn the MAC address of the switch module. However, there are certain devices, for example, a Solaris station, which will not learn a new MAC address for an IP when one already exists. If you are using one of these devices as an NMS station, and you are unable to ping the switch module, try erasing the switch module’s MAC address from the device’s ARP table and ping again.

4 Verify that the RS-232 terminal line is connected to the console port on the main switch module.

Procedure Execution

1 Reset the configuration of both switch modules by executing the

CFGFRMAT.BAT file supplied with your software.

To execute the CFGFRMAT.BAT file proceed as follows: a Perform the LMA command (1) SYS / (3) LOA / (3) LCL / 1 to put the system in Load Mode: Load.

b Reboot the switch using the LMA menu command: (1) SYS / (7) RBO.

The switch will reboot in debug mode.

c Transfer the RS-232 cable to the service port of the main switch module.

d From a DOS window on the LMA terminal execute

> cfgfrmat com speed where “com” is the communications port you are using and “speed” is 115200 for a CoreBuilder 7000HD switch module and 57600 for a

CoreBuilder 7000 switch module.

38 C HAPTER 4: I NSTALLING AND C ONNECTING C ORE B UILDER M ODULES e Transfer the RS-232 cable to the service port of the redundant switch module.

f Repeat step d) g Transfer the RS-232 cable to the console port of the main switch module.

Hardware Redundancy Setup

2 Set up the main switch module using the Integrated Fast Setup (see

“Integrated Fast Setup” on page 56). Do not reboot the switch from the

Integrated Fast Setup procedure (answer “no” to the prompt).

The main menu appears.

3 Wait for one minute to allow the configuration data to transfer from the main switch module to the redundant switch module.

4 Reboot the switch using the LMA menu sequence: (1) SYS / (7) RBO. This causes the configuration data to be recorded in flash memory and also causes the redundant switch module to become the main switch module.

5 After the switch reboots, answer “no” to the prompt: “Do you wish to erase the setup parameters”.

6 Run the Integrated Fast Setup procedure as in step 2) to verify that the setup parameters have been transferred correctly to the second switch

(the Integrated Fast Setup procedure now displays the setup parameters resident in the second switch module). Press Enter repeatedly to verify these parameters; do not enter new values.

7 Verify that the ELAN names in the LECS database are identical in both switch modules. Use menu item (2) LEM/(1) LCS/(5) LNT to check that the

LECS database of the second switch includes the ELAN name of the first switch. For example, Elan6666_0 - Elan6666_15

NMS-Based LANE Redundancy Setup

8 Verify connectivity between the switch module and the NMS station by pinging the switch module from the NMS station.

9 Load the Transcend application and open the Wizard Tool from the

ATMvLAN tool bar

10 Open the Backbone and Services Window.

11 Configure the LECS order as desired and press the Apply button.

12 Configure the LECS database. Add all the primary and redundant ELAN names desired to the LECS database and press Apply. Make a list of the

Switch Module 39

ELAN names you have selected. You will need them for setting up the other switch module.

13 When finished, close the Backbone and Services window.

14 Wait one minute to allow the LECS order database to transfer to the other switch module.

The LECS ELAN database does not transfer automatically.

15 Reboot the switch using the LMA menu sequence:

(1) SYS / (7) RBO

The purpose of this step is to make the first switch module active in order to set up the LANE services there.

16 After the first switch boots, check its connectivity with the NMS station as in step 8).

17 Perform steps 10) and 12) using the same list of ELANs.

18 Wait one minute.

Verifying LANE Redundancy Setup

19 Use the MIB browser under the Transcend tools menu and browse through the MIB to verify that all the information regarding the LECS order list has been transferred correctly.

Look in the following MIB location:

■ private

■ enterprises

■

■ atmForum atmForumNetworkManagement atmLanEmulation

■

■ elanMIB elanLecsGroup elanLecsConfGrou.

lecsConfTablelecsConfEntry lecsAtmAddrSpec

Press start query. The LECS order list is displayed on the bottom window.

20 Close the Backbone and Services Select window.

21 Open the Backbone and Services Select window again and use it to check that the LECS database is correct.

40 C HAPTER 4: I NSTALLING AND C ONNECTING C ORE B UILDER M ODULES

This item could be done through the LMA but it is preferred to do so through the NMS since the LMA will not show any redundant LES that exists.

22 Reboot the switch using the LMA menu sequence: (1) SYS / (7) RBO. The purpose of this step is to make the second card active in order to check the LANE services there.

23 After the second switch module boots, verify connectivity with the NMS station as in step 8).

24 Perform step 19) and 20) to verify LECS order.

25 Open the Backbone and Services Select window again and use it to check the LECS database is correct.

The hardware and LANE redundancy procedure is finished.

Cards

The 4-port ATM interface module can hold up to four ATM interface daughter cards. The installation procedure of the 4-port ATM interface module comprises two stages. First, you install the ATM interface daughter cards in the 4-port ATM interface module. Then, you install the

4-port ATM interface module into the CoreBuilder 7000 family ATM switch chassis.

To install the ATM interface daughter cards perform the following procedure:

1 Select the individual daughter cards that are to occupy the interface card’s four openings.

Align each module with the front panel aperture as shown in Figure 8

and press down to engage the strip connectors on the underside of the module. Three screws anchor each module to its seat on the interface card. Interface openings reserved for future use should be covered with blank panels. Used interfaces should use the coax or optical panels as covers.

Figure 8 4-Port ATM Interface Module

Installing a 4-Port

Interface Module

When the ports of the interface module have been fitted with the appropriate daughter card, you install the 4-port interface module into the CoreBuilder 7000 family ATM switch chassis.

To install the 4-port interface module:

1 Orient the interface module so its labelling is upright and be certain that the inject handles are in the outward position.

2 Insert the card into the chassis by placing it between the guides of the selected slot and sliding the card until it stops.

3 Be certain that the card sits in the guide slots on either side. Be sure that the loose screws do not interfere with card insertion.

44 C HAPTER 4: I NSTALLING AND C ONNECTING C ORE B UILDER M ODULES

4 Grab both inject handles and push them inward. This locks the card into the chassis. You may have to apply considerable pressure to the handles.

An audible “click” indicates that the connectors have engaged.

5 Tighten the card’s securing screws. You are now ready to connect cables to the appropriate ports of the module.

Replacing a 4-Port

Connecting the

Control Terminal

The CoreBuilder 7000 family ATM switch can be configured via the LMA using the Administration Console terminal (VT100) or terminal emulator

(Windows).

To connect a terminal to the CoreBuilder 7000 family ATM switch control port:

1 Prepare an RS-232 shielded cable (9 pin-to-9 pin or 9 pin-to-25 pin, as dictated by the terminal you wish to use).

2 Configure the terminal: 19200 baud, 8 data bits, 1 stop bit, no parity, xon/xoff flow control.

3 Push the DCE side of the cable onto the Control port of the switch module and screw it into place.

4 Connect the other end of the cable to the terminal.

In case you have installed a redundant switch unit, it is sufficient to connect the RS-232 line to either the active switch control port or to the redundant switch control port.

Connecting to the

Ethernet Port

The Ethernet port is used for connecting directly to a Transcend Network

Management System terminal for management purposes.

Connecting to Network Devices 47

In case you have installed a redundant switch module, its Ethernet port must also be connected directly to the Transcend NMS terminal.

Another way of connecting the Ethernet port to an out-of-band Ethernet network is to connect it to a CoreBuilder 7200 Ethernet/ATM Interface

Card or a CB7400 High Density Ethernet/ATM Interface Card installed in the same chassis.

Connecting to the

Power Source

7000 family ATM switch.

Software Loading and Diagnostics

Apply electrical power to the system by inserting the power cord in the power supply unit. The power supply indicator lights and the CoreBuilder

7000 family ATM switch automatically runs diagnostic software. This software verifies that every component in the system is fully functional before the system becomes active on the network. Diagnostics should take sixty seconds or less.

If any component fails power-on diagnostics, the system either fails to power on or it keeps faulty modules off-line. Once the system comes up, you can check to see which modules, if any, have failed diagnostics by checking the LED panels; in-depth information is available by viewing the system configuration screens on the administration console.

Indicators All interface and switching unit indicators light at the start of the power-on diagnostic sequence, then go out briefly. General activity LEDs light up as the system checks the switching and interface modules. Finally, individual port indicators go on as the system discovers active connections residing on the interface modules. The 10BaseT indicator on the interface module is on during normal function, even if there is no active 10BaseT management link.

Integrated Fast Setup Operation

Use the Integrated Fast Setup procedure to configure the minimum set of parameters needed to enable the CoreBuilder 7000 family ATM switch and its attached devices to function in the network.

With this procedure you can configure both the CoreBuilder 7000 family

ATM switch card and all CoreBuilder 7X00 interface cards installed in it in one session.

Integrated Fast Setup 57

In certain cases you will need to use the Fast Setup procedure of individual CoreBuilder 7X00 interface cards, in addition to the Integrated

Fast Setup procedure, to correctly configure your system.

This section presents the Integrated Fast Setup of the CoreBuilder 7000 family ATM switch card. It also explains when to use the Integrated Fast

Setup of the CoreBuilder 7000 family ATM switch card and when to use the Fast Setup of an individual Corebuilder 7X00 interface card. For detailed information about how to use the Fast Setup of an individual

Corebuilder 7X00 interface card, see the User Guide of the specific interface card.

Chassis-oriented Setup

The Integrated Fast Setup procedure is based on the concept that the

CoreBuilder 7000 family ATM switch chassis together with its installed interface cards is viewed as an integrated unit. The advantage of this point of view is its simplicity: it is not necessary to remember in which slot each interface card is installed or even which type of interface card is installed. Attention is focussed on configuring the ports of the chassis.

The procedure automatically determines the ports that are available in the chassis and presents them by type (Ethernet, Fast Ethernet, ATM) for configuration. The port location is displayed by the notation <slot.port>

For example <3.1> refers to slot #3, port #1.

Chassis-wide VLANs

With the Integrated Fast Setup, Virtual LANs (VLANs) can be created across the entire chassis. VLANs are set up in two stages. First, in the LE

Client section, a number of potential VLANs are created according to the requirement of the network. Next, in the Virtual Network Configuration section, the potential VLANs become actual VLANs by having ports assigned to them.

You need to define an administration “admin” VLAN to maintain SNMP connectivity to each device in the network. Using the Integrated Fast

Setup you define one admin VLAN for the chassis; there is no need to define separate admin VLANs for each interface card.

Note that from software version 3.5 on, the “admin” VLAN can now be called by any other name providing the same name is used consistently in the CB7000 and in all installed CB7X00 interface cards. When using the

Integrated Fast Setup, the name for the admin VLAN which is specified for the switch module will be automatically chosen for the other modules

58 C HAPTER 6: C ONFIGURING THE C ORE B UILDER 7000 F AMILY ATM S WITCH housed in the same CoreBuilder 7000 family ATM switch chassis, overriding any existing admin VLAN names.

Setup Modes The Integrated Fast Setup provides two setup modes: the “Full” setup mode and the “Switch” setup mode.

Full Setup Mode

The Full setup mode configures both the CoreBuilder 7000 family ATM switch and the installed interface cards. It sets the required parameter values in all the installed interface cards. The Full setup mode presents only the most critical parameters; default values are assumed for the remaining parameters.

This method is recommended for most users, especially for initial setup.

Only those systems that require specific parameter settings in one or more of the installed interface cards will require the Switch setup mode described in the next section.

Switch Setup Mode

The Switch setup mode focuses only on the CoreBuilder 7000 family ATM switch and its ATM ports. The Switch setup mode allows you to retain special settings in the interface cards. In this mode, the installed interface card configurations cannot be changed. If you want to alter the settings in an interface card, use the Fast Setup of that interface card after you are finished using the Switch setup procedure.

Setup Mode Selection

If one of the following conditions is detected, the operator is prompted to choose between the Switch and Full setup modes:

■

A Subnet Mask, Default Gateway or NMS Address different from that of the CoreBuilder 7000 family ATM switch

■

A VLAN whose ATM connection is set to “No”

The name of the ELAN to which the default admin port (Port #1 in each slot) is attached is not the same in all interface cards.

If none of these situations is detected, Full setup mode is automatically selected.

Integrated Fast Setup 59

If Full setup is selected, the parameters in the interface cards revert to their default values.

Setting Special Parameters

If one or more individual interface cards requires one of the special situations referred to in the previous section or needs to remain unaltered, you need to do one of the following:

■

Use the Switch setup mode of the Integrated Fast Setup to set up the

CoreBuilder 7000 family ATM switch only and then use the Fast Setup of each installed interface card separately.

■

Use the Full setup mode of the Integrated Fast Setup to configure the

CoreBuilder 7000 family ATM switch and all installed interface cards and then use the Fast Setup for the particular interface card in order to restore its special parameter values.

Interface Type Section This section prompts you for the ATM interface type configuration of the ports on the Interface Modules which are installed in the CoreBuilder 7000 family ATM switch chassis.

There are four interface types: UNI, E-IISP, IISP and PNNI. The UNI type is normally used when an edge device is connecting to a switch. The E-IISP type is normally used when connecting to another CoreBuilder 7000 or

9000 switch. The IISP type is used to connect to a device which does not recognize the E-IISP protocol used by the CoreBuilder 7000 family ATM switch such as switches of other vendors. The PNNI type is normally used to connect switches to other similar or different types of switches when you want each switch to have a global view of the entire network.

PNNI is available in version 4.5 extended only.

To enter the interface type configuration:

1 At the NNI type of port prompt, enter the NNI type for the port you just specified. Enter “U” for UNI, enter “E” for E-IISP, enter “I” for IISP, or “P” for PNNI.

2 Repeat step 1 until you have specified the interface type for all of the ports that are in the Corebuilder 7000 family ATM switch chassis.

Interface type

66 C HAPTER 6: C ONFIGURING THE C ORE B UILDER 7000 F AMILY ATM S WITCH

3 The LMA automatically prompts you to enter ATM addresses for the ports that you have specified as IISP. These are ATM addresses of network devices that you want the IISP port to recognize for routing purposes. They are placed in the routing table of the port. You need to enter these addresses manually because the IISP protocol does not automatically recognize them. You can enter more than one address; press Enter to end the sequence of addresses.

*** The following are addresses of ports you have defined as IISP.

You may enter more than one address per port.

When you have finished press <Enter>:

ATM address for port <5.2> (19 bytes-When less: end with '.*'):

47.00.00.00.00.00.3e.00.00.b0.00.c0.da.69.00.c0.da.11.22

ATM address for port <5.2> (19 bytes-When less: end with '.*'):

4 The LMA automatically prompts you for the NNI type of the ports that you have specified as IISP. Specify the NNI type as User or Network.

*** The following is a profile of ports you have defined as Gateway:

Profile of port <5.2> (U<ser>, N<etwork>): N

5 Repeat until you have specified all the IISP ports.

LE Client Configuration Section This section prompts you for the

LAN Emulation Client configuration. You give names to the ELANs that you want to be active in the network. In the Virtual Network

Configuration section, you will assign Ethernet ports to the ELANs you have named in this section to create VLANs. Until then, the ELANs are considered potential ELANs.

You can enter the names of resident ELANs of the switch you are setting up and you can enter names of ELANs from other devices in the network.

You can define any number of potential ELANs. To end the sequence, press Enter.

The names of the ELANs resident on a particular switch all have the form elanXXXX_n where “XXXX” is a number unique to the switch and “n” is

Integrated Fast Setup 67 the sequential number of the ELAN. This is the form you need to use for

ELANs that you enter in this section (except for the admin ELAN).

You are first prompted for the name of the admin VLAN. The default name displayed is the name of the admin VLAN of the CoreBuilder 7X00 which is installed in the highest occupied slot in the CoreBuilder chassis.

You can change it if you wish.

The name for the admin VLAN which is specified in this section will be automatically chosen for the other modules housed in the same

CoreBuilder 7000 family ATM switch chassis, overriding any existing admin VLAN names.

For this section and the Virtual Network Configuration section to operate correctly, at least one CoreBuilder 7X00 interface card must be installed in the CoreBuilder 7000 family ATM switch chassis.

The following shows a typical LE Client Configuration. Make a list of the

ELAN names and the numbers to which they are assigned in this section for later use in the Virtual Network Configuration section.

Additional Switch

Configuration

The Integrated Fast Setup configures a minimum set of network parameters - enough to get you started.

If you need to make changes or to perform additional configuration tasks, use individual items of the LMA menus. These are all described in the CoreBuilder 7000 Family ATM Switches Management Guide.

Some additional configuration tasks might be:

Additional Switch Configuration 73

Configuring SVCs

CoreBuilder 7000 family ATM switches use standard UNI 3.0, 3.1 or 4.0 switched virtual channel (SVC). SVC mode can be used when CoreBuilder is in a backbone or workgroup topology, with PVC used whenever necessary. ILMI enables automatic address registration for SVC. Addresses can be registered manually via the LMA menus.

Changing the UNI Version

The CoreBuilder will run UNI 4.0 SVC by default. You can work in UNI 3.0 or UNI 3.1 by choosing this option in the signalling setup menu.

Configuring Network Prefix and ATM Addresses

ATM addresses are essential for establishing a connection using SVC.

Most devices that support SVC, also support automatic address registration through the ILMI protocol.

A network prefix is essential for address registration to be executed. Refer to CoreBuilder 7000 Family ATM Switches Management Guide for proper network prefix setting.

For connectivity with devices that do not support ILMI, ATM addresses can be set manually using the Add ATM address function under ATM address setup in the Administration Console menus.

Configuring a PVC

Permanent Virtual Channels (PVC) can be used to connect to devices that do not support switched virtual channels (SVC) standard protocols. In the

CoreBuilder 7000 family ATM switch you can create point-to-point (P2P) and point-to-multipoint (P2M) connections. Use the Setup and

Configuration Connections menu, to create a PVC call, PTP or PTM. You can also create an out VC in a PTM call, release a PVC call, release an out

VC from call, save PVC connections in flash memory and reset saved connections. Up to 2000 PVCs can be configured.

Configuring Clock Synchronization

External clock synchronization allows a clock to be received on one of the bottom of 4 OC-3c ports of an 8-port interface card from an external source, and to be distributed to all bottom OC-3c ports on the same card and other 8-port interface cards in the same chassis. It is used in voice and data applications so that the same port is used at the same time. You can configure one port to be the master port which will distribute its

74 C HAPTER 6: C ONFIGURING THE C ORE B UILDER 7000 F AMILY ATM S WITCH information to the other ports (slave ports). For more information, see

“Set and Save Clock Synchronization Mode” on page 120 in the

Management Guide

Viewing Network

Statistics

At any time after configuring the CoreBuilder 7000 family ATM switch, you can view the available statistics to see how the network is functioning. For example, you may want to display the general statistics for an overview of the network, or the signalling statistics for protocol

information on specific ports. Table 17 lists the types of statistics

available. To view a specific statistic, enter the menu path shown in the table. For more information, see the CoreBuilder 7000 Family ATM Switch

Configuration

Upload/Download

You can store (upload) the configuration of an installed card from its flash memory to an external disk and restore it (download) to the flash memory of the original card — or to the flash memory of a different card of the same type — at a later time. You can initiate this operation only through the LMA and not via a SNMP management application like Transcend.

This feature lets you:

■

Back up your switch configuration in case of switch failure

■

Transfer the configuration from one switch to another

Maintain various standard configuration templates which can be loaded according to requirement

The configuration upload works for individual cards installed in the

CoreBuilder 7000: either the active switch card or a CoreBuilder 7X00

Interface Card. You select the card whose configuration you want to download or upload from a list of installed cards.

When the switch operates in single-IP mode, you can use this facility to upload the configuration of any of the installed cards through the LMA of the switch card. When the switch is operating in multiple-IP mode, you can use this facility to upload the configuration of the switch card only.

76 C HAPTER 6: C ONFIGURING THE C ORE B UILDER 7000 F AMILY ATM S WITCH

You cannot upload or download configuration parameters to a switch card while it is installed as a redundant switch card. You need to remove the card from the chassis, install it in a different switch chassis as the active switch card and then perform the upload/download operation, as described below. Afterwards, return the card to its slot in the original chassis.

Uploading Selected

Data Types

The CoreBuilder 7000 allows you to upload selected types of configuration data. The types of configuration data you can upload depends on the card you selected. For the switch card, the types of configuration data you can upload are as follows:

■

All Configuration Data

Platform Parameters

■

ATM Addresses

PNNI Configuration

LANE Security

PVC Connections

LECS Topology

■

LECS Order List

For a CoreBuilder 7X00 card, the data types are as follows:

Organizing

Configuration Files

The uploaded configuration files can be named using a naming convention of your choice. Normally, you will want to include information about the data type, the card type and a date or other identifier in the file name. For example, you might use file names like cfg_7000_12jun98 and static_7600_1.

When you download configuration data from the files on the disk to the card, you designate the card by its slot number. The slot can contain the original card from which the data was uploaded, or it can contain another card of the same type.

If you try to download configuration data which was uploaded from one type of card type to another type of card, an appropriate error message is issued.

Storing and Retrieving Configuration Parameters 77

Activating the

Downloaded

Configuration

When the configuration files are downloaded into flash memory, they overwrite the previous information. The new parameters are not activated immediately, but rather after the next reboot when they are read from the flash memory. The CoreBuilder 7000 assumes that the user wants to reboot the switch as soon as possible to activate the new configuration parameters. Therefore, subsequent to a configuration download, all LMA and SNMP set operations are blocked until the next reboot – except for the configuration upload/download and reboot operations.

It is recommended, therefore, to perform a configuration download only when you are ready to reboot and activate the new parameters.

Cards should not be “hot swapped” after a configuration download until after the next reboot.

Uploading the

Configuration of a

Card

To store (upload) the configuration of a card installed in the CoreBuilder chassis from flash memory to disk, first make sure that the switch is connected to the TFTP server and that it is in single-IP mode and then perform the following steps:

1 Perform the LMA menu command:

(1) SYS\ (3) LOA \(6) TCU

2 The LMA automatically presents you with a list of the installed cards whose configuration you can upload to disk, for example:

Module Types:

1<Switch module 7000>

2<Slot 3 - 7600>

3<Slot 4 - 7600>

4<Slot 5 - 7400>

5<Slot 6 - 7200>

Select Module: 1

Select the appropriate card from the list—for example, if you want to upload the configuration of the active switch card, select 1 from the menu.

Upgrading from

E-IISP to PNNI

For full upgrade instructions, see Chapter 6 in the

CoreBuilder 7000

Family ATM Switches Management Guide .The CoreBuilder 7000 has a special gateway function which allows E-IISP to PNNI connectivity and vice versa.

PNNI is available in version 4.5 extended only.

PNNI in E-IISP Connecting PNNI to E-IISP is done in two ways:

■

Using the 3.1 interface

■

Using the PNNI to IISP/E-IISP gateway

Connecting PNNI to E-IISP and IISP networks requires addressing to match

(use the same E.164 addressing scheme) in order to guarantee uniqueness. This is necessary because PNNI works on the best match routing scheme. The PNNI gateway function will advertise IISP and/or

E-IISP addresses as either native or as foreign reachability addresses.

84 C HAPTER 6: C ONFIGURING THE C ORE B UILDER 7000 F AMILY ATM S WITCH

Migrating from E-IISP to PNNI

In order to migrate successfully to PNNI, the network manager must review the network address scheme that will be used. There are two possible approaches to implementing address change:

■

Deriving a PNNI peer group ID and peer group level based on the E-IISP addressing scheme. See Chapter 3 in the Operations Guide for information on E-IISP addressing.

■

Changing the E-IISP network prefixes to match the PNNI addressing scheme.

The gateway between E-IISP and PNNI must be between the E-IISP highest level and the PNNI gateway node.

Using redundant switching cards and redundant power supplies.

Types of Power

Supplies

The CoreBuilder 7000 family supports three kinds of power supplies: an

AC unit rated at 90A, and two DC units rated at 90A and 40A. You can use each one of them in any CoreBuilder 7000 family ATM switch. The power supply supports two output channels: one 5V DC channel which supplies the CoreBuilder switch and the interfaces cards, and one 12V DC channel which supplies the fans.

86 C HAPTER 7: R EDUNDANCY IN THE C ORE B UILDER 7000 F AMILY ATM S WITCH

The CoreBuilder 7000 family power supplies are shown in Table 19.

Power Supply

Operation

Load Sharing

The power supplies can operate in load-sharing mode; two 90A power supplies can produce up to 180A. Providing that the power consumption of the unit does not exceed 90 A, load-sharing allows one power supply to serve as a backup.

Overloading

When the installed power supply is rated for less than the required power consumption of the CoreBuilder module, the CoreBuilder will not succeed in powering up. It will attempt to power up, hit the current overload rate and turn the power supply off, going through this cycle repeatedly until the load is reduced.

Calculating the Power

Consumption of

CoreBuilder Switch

The power consumption of an entire CoreBuilder 7000 family ATM switch unit is calculated by adding up the power consumption of the switching card(s) and interface cards installed in the chassis. Normally, the values for typical

power consumption can be used in the calculation. Table 20

shows the typical power consumption values for the CoreBuilder 7000 family ATM switching cards and interface cards.

Providing

Redundancy for

Various Power Loads

This section describes when redundant switch cards and redundant power supplies can be used in a CoreBuilder switch.

In order to determine whether a redundant switch card and/or an redundant power supply can be used in a CoreBuilder switch, the total power consumption of all installed cards must be examined. According to the total power consumption, there are three possibilities, as the following examples illustrate:

Installation I: The total power consumption of a single switching card

(that is, no redundant card installed) and all interface cards exceeds 90A.

In this case, a Dual 90A supply is required so that the second power supply cannot be redundant. A redundant switch card can be installed.

This “heavy load” installation is illustrated by the first example installation

in Table 21.

Installation II: The total power consumption of two switching cards

(i.e., redundant card installed) and all interface cards exceeds 90A but without the second switching card the consumption is less than 90A. In this case, either a redundant switch card or a redundant power supply can be installed, but not both. This “medium load” installation is

illustrated by the second example installation in Table 21.

Installation III: The total power consumption of two switching cards and all interface cards does not exceed 90A. In this case, both a redundant switch card and a redundant power supply can be installed.

The light load installation is illustrated by the fourth example installation

in Table 21.

In all installations that do not include multiple CB7600 cards both redundant switch cards and redundant power supplies can be installed.

Solving Common

Problems

The following problems may arise while working with the CoreBuilder ®

7000 family ATM switch. If your problem does not appear on this list, view relevant statistics and parameters using the Administration Console menus (refer to the CoreBuilder 7000 Family ATM Switches Management

Guide ). You can also contact 3Com Technical Support. Also, be sure to read through the release notes.

Table 13 Recommended Action for Common Problems

Problem

Terminal does not show anything

Recommended Action

If the control terminal is physically connected to the CoreBuilder 7000 family ATM switch, but does not load the Administration Console Menus, verify that your terminal setup

matches the specifications (see “Connecting the Control Terminal” on page 46). Also,

make sure your cable is configured as DCE (see “Ethernet Cabling” on page 118).

Port cables do not work

If the cables attached to the CoreBuilder 7000 family ATM switch interface ports do not work, check that the connectors are firmly snapped in place. Also, make sure that each wire connects to Rx on one end and Tx on the other.

ACT LED not blinking When the CoreBuilder 7000 family ATM switch is activated, the switch module and interface cards ACT LEDs should be blinking. If not, verify that the switch module and interface cards are properly inserted. Make sure that the control terminal is connected to the control port correctly, as an incorrect connection of this cable sometimes results in the inability of the system to function properly.

Table 15 Diagnostic Procedures

Procedure

Checking fan operations

Cleaning dirty fiber optic cables *

Action

In case of system overheating, check that the power supply fan and the fans in the fan tray are operating. To check for fan movement in the CoreBuilder 7000 family ATM switch’s fan tray, pull a few modules from the chassis to view the fans on the left side of the system.

Fiber optic transceivers are sensitive optical devices that need to be handled carefully. If dirt collects on the fiber optic lens, you may notice that the LED for an ATM port link status does not light. You may also notice degraded performance of that port, indicated by an increase in the physical layer statistics count for that port.

To prevent dust from collecting on the fiber optic lens, keep the dust covers on the ports at all times when they are not in use. To clean a fiber optic lens, follow the procedure below:

1 Remove any accumulated dust or debris from the port or connector by blowing off all surfaces with a canned air duster.

2 Compressed gas is recommended, such as Chemtronics’ Ultrajet ® or the Triangle Tool

Group’s Liqui-Too!™ Dust-A-Way. Do not use commercial compressed air or “house air” because of the risk of oil contamination.

3 Reconnect the cable to the port to see if the dusting corrected the problem.

4 If the LED still does not appear, or if it lights yellow, continue with steps 5 and 6.

5 Gently wipe the ports with a lint-free, non-abrasive, non-adhesive swab. Microswabs™ by Texwipe™ are recommended.

6 Gently wipe the connectors with a lint-free, non-abrasive wipe or pad. Texwipe™ pads are recommended.

* See safety precautions in next section.

Safety Precautions for Fiber Optics Connectors

Avoid touching all surfaces after cleaning the connectors, and keep all unused ports covered.

Vermeiden Sie das Berühren aller Oberflächen nach dem Säubern der

Kontakte und verdecken Sie alle nicht benutzten Öffnungen.

Ne toucher aucune surface après le nettoyage des connecteurs et garder les pièces inutilisées couvertes.

ITE

EQUIREMENTS

This appendix addresses the various requirements to be met when preparing the CoreBuilder ® 7000 family ATM switch site. This includes the following elements:

■

Performing all necessary planning, ordering, installing, and maintenance.

When required, contacting the appropriate facilities manager for assistance.

Ensuring that all building and electrical code requirements (national, state, and local) are met.

Environmental and

Safety

Requirements

This section includes environmental and safety requirements are applicable to the installation of the CoreBuilder 7000 family ATM switch.

Protective Grounding For your safety and to ensure optimum performance of the system, verify that all protective grounding requirements have been met in accordance with the applicable national, state, and local electrical codes.

You must also verify that you have properly grounded the distribution rack. This is normally done with a distribution rack grounding kit and a ground conductor that is carried back to earth or to another suitable building ground. Proper distribution rack grounding will ensure that voltages induced into wiring by lightning or other disturbances are directed to ground.

Environmental

Specifications

For the system to operate properly, the following environmental conditions should exist:

■

Ambient air temperature: 0° to 40° C (32° to 104° F).

Operating humidity: 10 to 95% relative humidity (non-condensing).

106 A PPENDIX C: S ITE R EQUIREMENTS

■

Power requirements: 115-Volts AC power, 15-Amp service receptacles, type N5/15 or NEMA 5-15R (for U.S.) or 220 Volts AC for

Europe.

Thermal

Recommendations

This sections contains recommendations for handling the heat generated by the CoreBuilder 7000 family ATM switch. It is essential that you provide a suitable environment for both performance and safety.

General

Recommendations

The following are some general thermal recommendations for the wiring closet:

■

Ensure that the ventilation in the wiring closet is adequate to maintain a temperature below 40° C (104° F).

■

During non-business hours, make sure that the ventilation is not shut down while a CoreBuilder 7000 family ATM switch remains powered up; otherwise, the equipment may overheat.

Power and Heat

Specifications

The following are power and heat specifications for the CoreBuilder 7000 family ATM switch:

■

Maximum power consumption: 250 Watts

Maximum heat generated: 1724 BTU per hour

Operating temperature: 0° to 40° C (32° to 104° F)

Wiring Closet

Considerations

The cabling system used at the facility should cover the majority of wiring closet concerns. You may want to consider the following recommendations.

■

Verify that the facility meets all requirements mentioned in the system cabling plan.

Ensure that the system is easily accessible for installation and service.

Use AC power, 15-Amp service receptacles, type N5/15 or NEMA

5-15R for 120Vac.

Select a vinyl floor covering for the wiring closet. (Concrete floors tend to accumulate dust, and carpets often cause static electricity.)

Ensure that the wiring closet floor is flat and level. If the floor is not level, ensure that the racks are bolted to the floor to prevent them from tipping over.

Distribution Rack Requirements 107

■

Ensure that all wiring closets have doors with locks to prevent unauthorized access.

Provide adequate overhead lighting in the wiring closet for easy maintenance.

Ensure that each wiring closet has a suitable ground. All metal racks, enclosures, boxes, and raceways in the closet should be grounded.

Assign wiring closet identification numbers using architectural location codes or some type of floor grid matrix.

Ensure that all system environmental requirements are met (such as ambient temperature and humidity).

Distribution Rack

Requirements

This section describes the basic mechanical and space requirements for

the distribution rack (refer to Figure 16).

Figure 16 Distribution racks

Mechanical

Requirements

Racks should comply with the standards and requirements mentioned in the cabling system plan and should conform to conventional standards.

In the United States, use EIA Standard RS-310C: Racks, Panels, and

Associated Equipment. In countries other than the United States, use IEC

Standard 297: Dimensions of Panels and Racks.

The following are distribution rack requirements:

108 A PPENDIX C: S ITE R EQUIREMENTS

■

Use an open style, 19-inch rack. The rack styles shown in Figure 16

facilitate easy maintenance and provide excellent ventilation.

The rack should use the universal mounting rail hole pattern identified in IEC Standard 297.

The rack should be made of steel.

The rack should support approximately 272 kilograms (600 pounds).

The rack should have adequate electrical grounding. A distribution rack grounding kit may be used.

The rack should be attached to the wiring closet floor with 9.5 millimeters (3/8 inch) lag screws or equivalent hardware. The floor under the rack should be level within 5 millimeters (3/16 inch). Use a floor leveling cement compound if necessary or bolt the racks to the floor.

Brace open racks if the channel thickness is less than 6.4 millimeters

(1/4 inch).

Install equipment in the lower half of the equipment rack to avoid making the rack top too heavy.

ABLING

EQUIREMENTS

This appendix addresses many aspects of installing optical fiber cabling to support the CoreBuilder ® 7000 family ATM switch environment. It also deals with modem cables and Ethernet and control cables for management. The following topics are covered:

■

Installing New Cabling

ATM Cabling

Ethernet Cabling

Installing New

Cabling

If you are installing new cabling, follow these guidelines:

■

3Com recommends that you use a cabling system plan, such as

AT&T's Premises Distribution System (PDS) or the IBM Cabling System.

■

Determine how many CoreBuilder 7000 units are going to be supported by each wiring closet, and how many downlink connections from these CoreBuilder 7000 units are planned.

Locate wiring closets to enable connections to the different floors.

■

To simplify installation of the network and to aid in troubleshooting, install a telephone in each wiring closet for communication between wiring closets, work areas, and other locations.

Include all linear distances (vertical rises, etc.) in the cable plan so that all cables - from wiring closet to desk and to other wiring closets - are under their respective maximum lengths.

Cable Labeling and

Record Keeping

A reliable cable labelling and record keeping system is essential when planning any network installation. A good cable labelling system provides enough information for you to locate the opposite end of any cable.

Maintaining accurate records helps you to:

■ relocate devices easily

110 A PPENDIX D: C ABLING R EQUIREMENTS

ATM Cabling

■

■ make changes quickly isolate faults in the distribution system

Consult the cabling system plan to set up the cable labeling and record keeping system best suited to the environment. Also consider the following recommendations:

■

Identify cables by securely attaching a label to the ends of all cables.

Draw a floor location grid matrix using the building floor plans. For easy reference, use this grid when assigning location numbers to cables.

Assign a unique block of sequential numbers to the group of cables that run between each pair of wiring closets.

Assign a unique identification number to each distribution rack.

Make all work areas and wiring closets easy to identify by labeling the front panel of the CoreBuilder 7000 and other hardware and by displaying the floor location grid and cabling plan in each wiring closet.

Keep accurate and up-to-date cable identification records, such as

IBM's Cable Identification Label Sheet or Cable Schedule. Post records near each distribution rack. On the appropriate cable schedule, record the following cable drop information: the cable source, destination, jumper location, and any additional information.

Make sure that optical and coax cables are labeled Rx and Tx accordingly.

When planning the installation, thoroughly inspect the present cabling to determine if it meets the specifications in the cabling system or standards used at the site.

In addition to adhering to the local standards, all cable must conform to the American National Standard ATM Physical Layer Medium Dependent

(PMD) standard, ISO.166-1990, American National Standards Institute, which defines the Physical Medium Dependent (PMD) layer of the ATM network. Currently, there are two approved PMD standards: Multi-mode

Fiber (MMF-PMD), which is defined in ANSI standard X.3-166-1992, and

Single Mode Fiber (SMF-PMD), which is defined in ANSI standard x.3-184-198x.

ATM Cabling 111

3Com supports multi-mode fiber (MMF-PMD) 62.5/125 µm and Category one (1) single mode fiber (short reach) (SMF-PMD). When deciding whether to use multi-mode or single mode fiber, determine the maximum interstation distance (the distance from the CoreBuilder 7000 to any potential end station):

■

If the maximum interstation distance is less than or equal to 2 kilometers (1.25 miles), use multi-mode fiber (MMF-PMD).

If the maximum interstation distance is greater than 2 kilometers (1.25 miles) and less than or equal to 14.4 kilometers (8.6 miles), use single mode fiber (short reach) (SMF-PMD).

Caring for Fiber Optic

Transceivers

Fiber optic transceivers are sensitive optical devices that need careful handling. The following information offers suggestions about caring for fiber optic cable.

Dirt on the Fiber Optic Lens

If dirt collects on the fiber optic lens, you may notice that the LED for an

ATM port either does not light or lights yellow. You may also notice degraded performance of that port, as indicated by a decrease in the Link

Error Rate (LER) estimate for that port.

To prevent dust from collecting on the fiber optic lens, keep the dust covers on the ports at all times when they are not in use. To clean a fiber

optic lens when it becomes dirty, see “Cleaning dirty fiber optic cables” on page 95.

Damaged Transceiver Due to Excessive Insertion Force

The ATM specification for insertion force on the connector into an ATM

SC receptacle is 3.5 lbs. However, it is possible to exert up to 30 lbs. of insertion force on the transceiver if you are too forceful while inserting the SC connector into the receptacle. This can cause failure of the transceiver's mechanical joints, permanently damaging the part and disabling the port.

When inserting connectors into the ATM ports, gently insert the SC connector into the receptacle until you hear the connector click into place. Use only enough force to engage the connector in the receptacle - no more than 3.5 lbs. This will avoid damage to the transceiver.

112 A PPENDIX D: C ABLING R EQUIREMENTS

Multi-mode Fiber

Standards

The MMF-PMD standards define the requirements for an ATM cable plant to support an interstation distance of up to 2 kilometers (1.25 miles) of multi-mode fiber. The cable plant includes all fiber optic components between any two communicating ATM devices and their associated

“station-to-network” connectors at each end.

To determine whether the cable plant complies with the MMF-PMD standard, do the following:

1 Compare the specifications of the fiber you are using to standard

specifications, as described in Table 25 and Table 26.

2 If unlike fibers are mated in the cable plant, calculate insertion losses to see whether they exceed the maximum attenuation value allowed for a

link, as described in Table 27 and Table 28.

3 Verify that the fiber's modal bandwidth is within an acceptable range for

the length of the link, as described on page 115.

The following sections describe each of these steps and give examples.

Comparing Fiber to Specifications

Compare the specifications of the fiber you are using to those in the following tables. If the fiber does not meet the specifications, use a different fiber or contact 3Com's Technical Support.

The fiber you use must meet the specifications listed in Table 25, which

describes the standard set forth in MMF-PMD. Table 26 describes

62.5/125 cable, commonly sold as “ATM Spec,” which meets all the requirements of the MMF-PMD standard.

Calculating Insertion

Losses for Unlike

Fibers

If unlike fibers are mated in the cable plant, calculate insertion losses to be certain that the cable plant does not exceed the maximum attenuation

value listed in Table 25. To calculate the insertion loss, consider the types

of fiber in the cable plant and the connectors or splices used to join them.

Compare the result to the maximum attenuation value listed in Table 25.

If the result is greater than the value in the table, use only like fibers in the cable plant.

Refer to Table 27 for the insertion losses of the fibers themselves. Use

Table 28, which lists the losses for connectors, cables, and splices, if the

specifications for these components are not available.

Use Table 27 for fiber-to-fiber connections only, not for power launched

from a transmitter.

Example

Suppose that a link consisting of one km of 62.5/125 fiber with a maximum attenuation rating of 1.75 dB/km is transmitting into one km of 50/125 fiber with a maximum attenuation rating of 3 dB/km. The fibers are joined using a fusion splice rated at 0.3 dB and the link contains one in-line ST connector rated at 0.6 dB.

The following calculation would arrive at the link loss attenuation value for this linked fiber:

62.5

+ ST connector loss

+0.6 dB

+ insertion loss *

+2.2 dB

= Total link attenuation

=7.85 dB

ATM Cabling 115

Because the resulting value, 7.85, does not exceed the maximum attenuation value, no adjustments are needed in the types of fibers joined or how they are connected. The link meets all of the specifications of the

MMF-PMD.

Verifying Modal

Bandwidth

The bandwidth of an optical fiber is the lowest frequency where the magnitude of the baseband frequency response has decreased by 3 dB compared to the magnitude at zero frequency. Bandwidth for multi-mode fiber is referred to as modal bandwidth because it varies based on the modal field (or core diameter) of the fiber. Modal bandwidth is specified in units of MHz • km, which indicates the amount of bandwidth supported by the fiber for a one km distance.

The modal bandwidth specified in Table 25 is 500 MHz

• km, which allows the cable plant to support end-to-end bandwidth of 250 MHz at the maximum 2 km distance. As a check, use the following formula to verify that the bandwidth of the fiber is within an acceptable range: n MHz • km / xkm = y MHz

In this formula, n is the amount of bandwidth available according to the fiber specification. Divide this number by the total length x of the fiber in kilometers. The result is the modal bandwidth y , measured in MHz.

If the result is lower than 250 MHz, the link may increase bit errors. To reduce the likelihood of bit errors, shorten the length of the fiber or use different fiber until the result of the calculation reaches 250 MHz.

Example. Cable with a modal bandwidth of 500 MHz • km will have 250

MHz of bandwidth at 2 km:

(500 MHz • km) / 2 km = 250 MHz

The same cable would have 500 MHz of bandwidth at 1 km. A fiber cable with a bandwidth specification of 200 MHz • km would have only 100

MHz of bandwidth at 2 km, which would not support ATM. In this case, another type of fiber would be required.

Single Mode Fiber

Standards

The SMF-PMD standard defines the requirements for an ATM cable plant to support a connection distance of up to 14.4 kilometers (8.6 miles) of single mode fiber. The cable plant includes all fiber optic components

116 A PPENDIX D: C ABLING R EQUIREMENTS between any two communicating ATM devices and their connectors at each end.

To determine whether the cable plant complies with the SMF-PMD standard, do the following:

1 Compare the specifications of the fiber you are using to standard

specifications, as described in Table 29.

2 If you mix equipment supporting Category 1 and Category 2, verify the

maximum attenuation between the equipment, as described in Table 30.

The following pages describe each of these steps and give examples.

Comparing Fiber to

Specifications

Compare the specifications of the fiber you are using to those in Table 29.

If the fiber does not meet the specifications, use a different fiber or contact 3Com Technical Support.

The single mode PMD specification (SMF-PMD) defines two optical power categories: Category 1 and Category 2. These categories refer to the optical power that must be launched into the fiber by the transmitter or detected by the receiver. 3Com currently supports only Category 1 single mode fiber.

The specifications for the standard single mode fiber are listed in

Table 29. Refer to the Category 1 specifications in this table for fiber

connecting 3Com equipment. For fiber used with Category 2 equipment from another vendor, refer to the Category 2 specifications.

The cable plant for a Category 2 implementation must have a minimum loss of 15.0 dB. In a Category 2 implementation, minimum cable plant losses are required to avoid saturating (blinding) the receiver.

DS-3 Coax Cables Connect the CoreBuilder 7000 DS-3 interface by a 75 Ohm coaxial cable that complies with DS-3 standards. The maximum cable length is 450 feet. To connect the DS-3 interface:

1 Prepare two coax cables - one for Tx and one for Rx. You may want to mark the ends of the cables to identify them easily.

2 Connect both cables to the DS-3 BNC connectors on the CoreBuilder interface. Make sure to connect Rx and Tx cables according to what is indicated on the interface front panel.

3 Connect the two cables at the other end according to the opposite of the first connection Rx to Tx and Tx to Rx.

Ethernet Cabling

The Ethernet port of the CoreBuilder allows you to connect the

CoreBuilder to an Ethernet network for Network Management Station

(NMS) connectivity (such as Transcend™). The Ethernet port is a standard

RJ-45 connection of a terminal side.

Follow these guidelines for 10BASE-T cabling:

■

Use only copper, unshielded twisted-pair (UTP) wiring. Do not use flat, multiconductor cable (for example, silver satin), which is often identified by solid colors such as red, green, yellow, or black.

Ethernet Cabling 119

■

Use two twisted-pairs for each link.

Use twisted-pair wire that is 22-26 AWG (0.5 millimeter) in diameter.

Use twisted-pair wire with an impedance between 85 and 115 ohms.

Make sure that the maximum twisted-pair link length from the system to any potential workstation location is 100 meters (328 feet).

Cable Pinouts Management connections may be established with a direct cable link to a

PC-AT serial port, or via modem. The following tables detail cable pinouts for 9 and 25 pin PC-AT links, and for a modem connection.

CoreBuilder 7000 Serial Port

The CoreBuilder 7000 provides a standard DB-9 connector for
