Part 1. Connecting

This part consists of three chapters which describe the procedures for changing user-accessible hardware (located in a reserved area) by qualified customer personnel:

• Chapter 1,3745 Models 210 to 61A: Connecting LlCs and Cables, and

• Chapter 2,3745 Models 130 to 17A: Connecting LlCs and Cables, describe the procedures for changing:

Line interface couplers

Line interface coupler cables

High-speed scanner cables

Token-ring adapter cables

Ethernet LAN AUI cables

Operator console cables

Remote support facility cable

Customer power control cable.

• Chapter 3,3746-900: Installing LCBs and ARCs, Connecting Cables, describes the procedures for changing:

Ethernet Bridge cables

Multiaccess Enclosure cables

Token-ring interface coupler type 3 cables

Line interface coupler types 11, 12, and 16 cables

Line connection boxes (LCBs)

Active remote connection (ARC) assemblies and cables.

These procedures are performed at initial installation and durtng later modifications of your 3745,3745 Models A and 3746-900.

Initial installation refers to the first installation of your 3745, 3745 Models A and

3746-900 or its re-installation after moving the machine. This is done with the help of the IBM service representative.

Later modifications refer to changes made at any other time. These later modifications do not require a service representative.

Notes:

1. While using the procedures in this part, the 3745/3746-900 can be powered

ON.

2. For the 3746-900, only the TIC3 cables can be changed by the user. Adding, removing, or changing the TIC3s themselves is done by the IBM service representative.

Chapter 1. 3745 Models 210 to 61A: Connecting LlCs and

Cables

o

This chapter gives all the procedures for the 3745 (Models 210 to 61A) hardware connection tasks. If this is the initial installation of your communication controller, the following cabling order is recommended:

1. Plug in any Ethernet LAN access unit interface cables.

2. Plug in any high-speed line cables

3. Plug in any token-ring cables.

4. Install cables for the operator console1, remote support facility2, any remote2 or alternate2 console, and customer power control.

5. Install any line interface couplers or their cables.

Attention - - - - - - - - - - - - - - - - - - - - - - - - - ,

By touching inside the machine, you can cause electrostatic discharges (ESDs) that may result in errors in the system operation, or damage to the equipment. .

Therefore, it is very important that you touch the ESD plate before you touch any element inside a unit or before you plug in a cable. The ESD plate is located on the inside face of the frame door .

Getting Started

Use this procedure to start all the connection procedures given later in this chapter.

Notes ----------------------------------------~

1. Updating the CDF

In the procedures for the TRA and HSS cables and the LlCs there are steps for updating the configuration data file (CDF) and then activating the lines. If you are connecting several kinds of lines, wait until all of the lines are connected before using the Upgrade or Update procedure.

For LlC types 5 and 6 integration, refer to the LlCSI6 Migration

and Integration Guide, SA33-0416 or earlier version of the

Connection and Integration Guide, SA33-0129.

Do not forget to test the LlCs and ask the host operator to activate all affected lines after updating the CDF.

2. Labels

Before the initial installation all external cables from DTEs/DCEs to the 3745 must be labeled. Use the information on the plugging sheets normally stored in the Preparing for Connection,

GA33-0127, or the Migration and Planning Guide, GA33-0183.

Do not forget to add or change the cable labels when you make later modifications.

Step 1 Have the plugging and configuration sheets from the Migration and

Planning Guide, GA33-0183

Depending on the procedure, you need the plugging and configuration sheets for the:

• Line interface couplers (LlCs)

• Line interface coupler (LlC) cables

• Token-ring adapter (TRA) cables

• High-speed scanner (HSS) cables

• Ethernet LAN attachment unit interfaces (AUls)3

• Operator console cables

• Remote support facility (RSF) cable.

There is no plugging sheets for the customer power control (CPC) cable.

Step 2 Opening the door

Notes:

• The figures below show a 3745 configuration with the maximum number of LlC units available.

• The doors marked with dashed lines are not user-accessible.

Unplugging or Plugging In an Ethernet LAN AUI Cable

IMPORTANT----------------------------------------~

Install only AUI cables that conform to ISO 8802-3.

The ISO 8802-3 says:

IThe connector is not specified to prevent operator contact with the shield, precautions shall be taken at installation time to ensure that the installer is warned that the shield is not brought into contact with any hazardous voltage while being handled by operating personneL

II o

ATTENTION -----------------------------------------------,

To attach your communication controller to the Ethernet LAN, the SQE TEST switch on the MAU must be set to ENABLE. If this is not done when you connect the AUI to the 3745, operation of the Ethernet LAN may be interrupted. o

Step 1 Starting

Before beginning, you must first do the procedure "Getting Started" on page 1-2.

There is a locking latch attached to the 3745 ELA connector. It is hard to see as it is between the cable connector and the 3745. In this procedure you may have to depend on feeling the latch with your fingertips rather than seeing it. It is sometimes hard to move, you may need to try more than once.

Getting Started

Use this procedure to start all connection procedures given later in this chapter.

Notes ------------------------------------------.

1. Updating the CDF

I n the procedures for the TRA 'and HSS cables and the LlCs there are steps for updating the configuration data file (CDF) and then activating the lines. If you are connecting several kinds of lines, wait until all of the lines are connected before using the Upgrade or Update procedure.

For LlC type 5 and 6 integration, refer to the LICS/6 Migration and Integration Guide, SA33-0416 or earlier version of the

Connection and Integration Guide, SA33-0129.

Do not forget to test the LICs and ask to host operator to activate all affected lines after updating the CDF.

2. Labels

Before the initial installation all external cables from DTEs/DCEs to the 3745 must be labeled. Use the information on the plugging sheets normally stored in the Preparing for Connection,

GA33-0140, or the Migration and Planning Guide, GA33-0183.

Do not forget to add or change the cable labels when you make modifications.

Step 1 Have the plugging' and configuration sheets from the Migration and

Planning Guide, GA33-0183.

Depending on the procedure(s), you need the plugging and configuration sheets for the:

• Line interface couplers (LlCs)

• Line interface coupler (LlC) cables

• Token-ring adapter (TRA) cables

• High-speed scanner (HSS) cables

• Ethernet LAN attachment unit interfaces (AUls)3

• Operator console cables

• Remote support facility (RSF) cable.

There is no plugging sheets for the customer power control (CPC) cable.

Step 2 Opening the door

Open the rear door of the 3745 unit by pushing in and turning the screws using the special door key.

If you want to work with the Lies, go to "Removing or Installing a Line

• "Unplugging or Plugging In a Token-Ring Adapter (TRA) Cable" on page 2-7

• "Unplugging or Plugging In a High-Speed Scanner (HSS) Cable" on page 2-8.

Unplugging or Plugging In an Ethernet LAN AUI Cable

IMPORTANT----------------------------------------~

Install only AUI cables that conform to ISO 8802-3.

The ISO 8802-3 says:

"The connector is not specified to prevent operator contact with the shield, precautions shall be taken at installation time to ensure that the installer is warned that the shield is not brought into contact with any hazardous voltage while being handled by operating personnel."

ATTENTION - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - ,

To attach your controller to the Ethernet LAN, the SQE TEST switch on the

MAU must be set to ENABLE. If this is not done when you connect the AUI to the 3745, operation of the Ethernet LAN may be interrupted.

Step 1 Starting

Before beginning, you must first do the procedure "Getting Started" on page 2-2.

There is a locking latch attached to the 3745 ELA connector. It is hard to see as it is between the cable connector and the 3745.

Note: For your convenience, plug the lower cables first.

1. Locate the cable using the port number written on the rabel.

2. Orient the plug and push it strongly into the corresponding port in the

LIe, until it clicks.

If necessary, examine the port and the socket to orient the plug correctly before insertion.

If the LIe is a type 3, check the plugging diagram to determine which of the two sockets should be used.

Repeat this step for every Lie or Lie cable to be installed.

Step 9 Updating the CDF

Go to "Upgrading or Updating CDF" on page 5-7 and perform the steps as instructed, then continue with the next step.

Step 1 0 Testing the LlC 1, 3, or 4

If you only removed L1C or L1C cables, go to Step 12.

For new L1C or L1C cables installed, refer to the wrap test (WTT) function in the Advanced Operations Guide, SA33-0097 and perform the automatic wrap test at the Lie level. NCP must be loaded to run WTT.

Step 11 Activating lines

Ask the host operator to activate the line(s) of all newly installed LlC(s) or LIe cable(s).

Attention - - - - - - - - - - - - - - - - - - - - - ,

If one of the affected lines was not deactivated at Step 3 on page 2-14, you may be forced to re-Ioad the NCP.

Step 12 You have finished this procedure

If you have no other connection tasks to do, replace the cable-retaining bar and ground plate assembly (if you removed it at Step 8 on page 2-16), close, and lock the door using the special key.

Note: The ground plate serves to reduce the possibility of radio frequency interference that might be caused by the operating machine.

A proper installation of the ground plate is necessary to meet FCe requirements, and to conduct electrostatic discharges to ground. o

Part 2. Integrating

This part explains the procedures used to integrate hardware and software configuration changes into your network. It contains two chapters:

• Chapter 4, "Starting the 3745 Integration," guides you through the following chapters according to your present task.

• Chapter 5, "Integration Procedures":

Has an introduction to MOSS-E use for integrating changes in the:

- MOSS

- MOSS-E

- service processor

- and 3746-900.

Some of these are:

- Changing the MOSS-E and DCAF passwords

- Verifying that the hardware (LiC types 11, 12, and 16, LCSs, and

ARCs) changes have been recognized by the MOSS-E

- Modifying and saving the configuration data file - extended (CDF-E).

Gives the procedures for using the MOSS functions for integrating changes in the 3745 base frame. Some of these are:

- Changing passwords, if you do not have a Model A

- Modifying the configuration data file (CDF)

- Backing up the MOSS hard disk.

Note: Before using the procedures in Chapter 5, the 3745 (and 3746-900, if you have one) must be powered ON. o

Chapter 4. Starting the 3745 Integration

The 3745 runs under the control of the Network Control Program (NCP). Any configuration changes that you make must be known to NCP. You use the MOSS

(or the MOSS-E, if you have it) to inform the NCP of hardware changes through the

MOSS configuration data file (CDF) and the MOSS-E configuration data file - extended (CDF-E).

These procedures are performed at initial installation and during later modifications of your 3745. o o

Initial installation refers to the first installation of your 3745 or its re-installation after moving the communication controller. This is done with the help of the IBM service representative.

Later modifications refer to changes made at any other time. These later modifications do not always require a service representative to be present.

•

To log on and navigate in the MOSS-E functions refer to the Basic Operations

Guide, SA33-0177.

There is on-line help to guide you through the MOSS-E functions.

Initial Installation

Provide the service representative with your planning worksheets from the Migration and Planning Guide, GA33-0183.

When the IBM service representatives have finished installing or upgrading your controller:

• You may change the MOSS-E passwords yourself using the Manage

Passwords function which is in the Operation Management task of the

Service Processor menu. For more information refer to the Basic Operations

Guide, SA33-0177. The default is the same for all passwords: IBM3745.

• If you have controlling workstations to remotely access the service processor, you may change the IBM Distributed Console Access Facility (DCAF) program password. This is the password that a DCAF remote console operator must use to connect to the service processor.

To change this password use the MOSS-E function Customize DCAF Target

Settings which is in the Configuration Management task of the Service

Processor menu. For more information refer to the Console Setup Guide,

SA33-0158.

• To receive regular and periodic microcode updates from RETAIN* use the

3745 All Models & 3746-900: CIG

o

Upgrading or Updating CDF

There are two related procedures that use the MOSS· CDF function to change the data in the configuration data file (CDF): o

• CDF Upgrade

This procedure causes the CDF to record all hardware changes that you are making to the telecommunication lines connecting to the 3745. These include

LlCs and cable changes for LlCs, token-ring adapters· (TRA), and high speed scanners (HSS).

Note: The Upgrade function is disruptive. While using it, all lines attached to the CCU that is being upgraded have to be taken out of operation for

15 minutes and the control program must be re-Ioaded.

• CDF Update

This procedure causes the CDF to record certain hardware changes that you are making to the telecommunication lines connecting to the 3745.

It also displays or modifies the telecommunication line parameters. o

When to Use

Upgrad~

or Update

Not Always Necessary - - - - - - - - - - - - - - - - - - - - ,

It is not always necessary to change the CDF:

• If you remove or install an Ethernet LAN AUI cable, no CDF change is necessary.

• Another example is if you replace a Lie by a spare LlC of the same type, and do not change the line configuration. If you are unsure, use the

Display/Update CDF procedure, and verify the actual configuration. o o

At Initial Installation

First perform an Upgrade for the hardware changes, then, if you want to verify or change the line parameters, perform an Update.

During a Later Modification

If you want to display or modify line parameters, perform an Update.

If you have made TRA cable change, perform an Upgrade.

If you have made other hardware changes, you can use either Upgrade or

Update depending on the changes you made. In general, use Update for a small number of hardware changes; use Upgrade for many changes, but:

• If the MOSS is not alone, you· can· use Update to record hardware changes without halting your system. You can at the same time make line parameter changes.

The only disadvantage is the time it takes to enter each hardware change and the possibility of errors during data entry.

• If you can stop your system approximately 15 minutes, use Upgrade. The hardware changes are put into the CDF automatically, quickly, and are less error prone.


5-7

The following table compares the two procedures:

Upgrade Procedure

• Is disruptive at CCU level

• Control program removed

• MOSS must be alone

• Modifies the CDF to record hardware changes when:

Changing a LIe

Changing a L1C cable

Changing a TRA cable

Changing an HSS cable.

Update Procedure

• Is disruptive only for the concerned scanners

• Control program remains active

• MOSS must be on-line

• Modifies the CDF to record hardware changes when:

Changing a L1C

Changing a L1C cable

Changing an HSS cable.

• Displays LIe, HSS, TRA, and Ethernet

LAN adapters (ELA) line parameters and L1C information

• Modifies L1C and HSS line parameters.

For more help, refer to the CDF function in the Advanced Operations Guide,

SA33-009?

Upgrade Procedure

• If the MOSS is already running alone (the CCU control program is not operational), begin at Step 8 on page 5-9.

• If the MOSS is not running alone, then you must use the reset (RST) MOSS function to remove the control program from the CCU(s):

Line Weight Calculation

The line weight is the percentage of the low-speed scanner capacity that the line uses. For example, five lines each with a weight of 20 take up 1000;0 of the capacity of a low-speed scanner. Spare (unused) lines have a weight of zero.

The line weight is given by the following formula: Weight

Line Speed I C.

"e" is a coefficient related to the line protocol.

The values of the coefficient "e" are given in Table A-2 for Lie types 1, 3, 4A and

Scanner Capacity

The maximum number of LlC positions supported per low-speed scanner depends on the line with the highest transmission speed connected to the scanner, and is limited by the LlC enclosure capacity.

Mixing Line Interface Couplers

To calculate the capacity of a low-speed scanner (LSS) connecting LlCs with one or four ports, the following rules apply:

1. One-port LlCs : LlC types 3, 4B.

2. Four-port LlCs: LlC types 1 and 4A.

Mixing One-Port and Four-Port Lies

If one-port LlCs are mixed with four-port LlCs on the same scanner, you should consider:

• The permissible number of one-port Lies with the highest speed.

• The permissible number of four-port Lies with the highest speed.

Then, compare the two numbers and use the lower number.

Spare Lines

Spare (unused) lines have a weight of zero. o o

Selective Scanning

For more details on selective scanning, refer to the Introduction, GA33-0092 (for

Models 210 to 610) or GA33-0138 (for Models 130 to 170). This information also applies to the Models A.

Unlike LlCs in earlier communication controllers, 3745 Lies are only scanned if at least one of the lines connected to them is activated. Lies with inactive lines do not contribute to the scanner load.

Note: A LlC leaves the scan ring only after all the active lines on the Lie are deactivated by a Disable command from the control program. An X.21 DTE Clear command to a X.21 switched line does not disable the line for selective scanning. o

Appendix B. Communication Line Processor Characteristics and Line Weights

This appendix explains:

• The communication line processor (CLP) characteristics (interfaces and connectivity)

• The standard line weights and the associated assumptions about the traffic and lines

• How the 3746 configurator, CF3745, assigns communication lines to CLPs using these line weights. o o o o

Characteristics of the CLPs

The communication lines can operate in half- or full-duplex mode and use the

SDLC, PPP, Frame-relay, or X.25 line protocol, but not SSC and asynchronous

(start-stop) line protocols. The primary access to Euro-ISDN via LlC 16 uses

Frame-relay framing.

Note: ISDN connections are not supported by the 3746 network node nor the

3746 IP router. They are supported by the 3746-900 with the necessary programming support: NCP for SNA and CNN controlled traffic for APPN.

The communication line adapters support:

• V.24 leased and switched lines (600 bps up to 28.8 kbps)

• V.35 leased lines (56 kpbs up to 2.048 mbps)

• X.21 leased lines (600 bps up to 2.048 mbps)

• V.25 bis protocol over V.24 switched lines.

The 3746-900 does not support the ITU-T X.21 switched lines.

If necessary, adapters configured in the 3745 can compliment the 3746-900 configuration to provide support for:

• SSC lines

• Asynchronous (start-stop) lines

• Low speed X.21 switched lines

• Emulation Program (EP).

Communication Line Processor Connectivity

The maximum physical connectivity of one CLP can be either:

• 4 high-speed lines up to 2 mbps

• 32 medium-speed lines up to 256 kbps

• 120 medium- and low-speed lines up to 64 kbps being either:

(V35/x.21) line interfaces

(V24) line interfaces

The CLP connects up to four line interface couplers (LlCs) in any mix.

8-1


The LlC 12 provides one line interface (either ITU-T V.3S or X.21) operating at speeds up to 2 mbps.

The LlC 11 connects up to 30 lines (ITU-T V.24, V.3S, and X.21) at speeds up to

64 kbps, or 8 lines (ITU-T V.35 and X.21) at speeds up to 256 kbps, or a mixture of these line speeds. A" 30 line interfaces, the active remote connectors (ARCs), are housed in two line connection boxes (LeBs) of 15 slots each. This pair of LCBs is connected to a Lie 11 via a single cable up to 105 m long.

The Lie 16 provides Primary Rate Interface (PRI) ISDN operating at 2.048 mbps.

If the speed of a line is greater than 64 kbps, selective scanning is used to prevent the unnecessary scanning of the remaining unused slots in the LeB area.

The maximum operational capacity of the CLP depends on your specific network and traffic characteristics.

Maximum Configuration of a 3745 with a 3746-900

Table 8-2 gives the maximum configuration of the 3745 Models A with only a

3746-900 attached. There are no 3746-Axxs or Lxxs installed.

Note: Some items in Table 8-2 are mutually exclusive. Therefore, not all the maximum connection capabilities are possible on the same machine.

The maximum operational capacity may be lower than the maximum physical capacity given in table. For example, the maximum number of active lines (600) in a 3746-900 can be reached with a mix of line speeds ranging from 600 bps up to 64 kbps.

Configuring Communication Lines on the 3746-900 (Line Weights)

The CLPs perform the data link control and traffic routing for the lines connected to the 3746-900. In the 3746-900, the CLPs also perform the data link control for the lines activated by the NCP. The contribution of an individual line to the CLP load depends on the:

• Traffic type: IP, HPR/ANR, HPR/RTP, APPN/DLUR, or NCP

• Line speed

• Line protocol (Frame-relay, SDLC, X.25, PPP)

• Type of mode: duplex or half-duplex

• Percentage of line utilization, including messages sent by users and applications, control information (such as acknowledgements, status frames

(ANR), and so on). Line utilization is mainly influenced by the size and rate of data messages exchanged between users and applications.

CF3745 Hardware Configurator (Standard Line Weights)

Standard Line Weight Assumptions

The 3746 hardware configurator (CF3745) assigns lines to the CLPs by using standard line weights. For a given speed, this line weight represents the line contribution to the CLP load for a typical line utilization (%) and mix of traffic. The

CF3745 assigns the lines to the CLPs without exceeding 90% of CLP load under the assumptions of the standard line weights.

For a given transmission speed, Table 8-5 on page 8-5 shows the standard line weights. The corresponding standard CLP connectivity is shown in Table 8-6 on

8-4

3745 All Models & 3746-900: CIG o o

o o page 8-6. The weights and number of lines per CLP are indicated for the possible line protocols, SOLC, Frame Relay, PPP, X.25, and traffic types. Most of the standard default parameters of the CF3745 performance model are assumed for the standard line weights.

For more information, refer to the Migration and Planning Guide, GA33-0183.

Standard Line Weights and CLP Connectivity

The line weights corresponding to the "Standard Line Weight Assumptions" on page 8-4 are used by CF3745 to determine the required number of CLPs and to automatically assign the lines to these CLPs. The CF3745 authorizes a maximum

CLP weight of 100, which corresponds to a theoretical CLP load of 90%.

The actual required number of CLPs, as determined by CF3745, also depends on the physical connectivity requirements.

This glossary defines new terms used in this manual. It also includes terms and definitions from the IBM Dictionary of Computing,

SC20-1699. o o

Advanced Communication Function (ACF). A group of IBM licensed programs. principally VTAM programs. TCAM, NCP, and SSP, that use the concepts of Systems Network Architecture (SNA), including distribution of function and resource sharing. advanced peer-to-peer networking (APPN).
