CHAPTER 2

NETWORK REQUIREMENTS

This chapter contains general networking guidelines. Before attempting to use the 8H02-16 or to install a Fast Ethernet Interface Module

(FE-100TX or FE-100FX), review the requirements and specifications outlined in this chapter.

2.1

NETWORK REQUIREMENTS

The network installation must meet the guidelines included in this chapter to ensure satisfactory performance of this equipment. Failure to follow these guidelines may produce poor network performance.

Refer to the following sections that apply to your specific network configuration.

2.1.1

10BASE-T Twisted Pair Network

When connecting a 10BASE-T twisted pair segment to any of the

8H02-16 ports (Interfaces 1 through 14), ensure the network meets the following requirements:

Length

The IEEE 802.3 standard for 10BASE-T requires that 10BASE-T devices transmit over a 100 meter (328 foot) link using 22–24 AWG Unshielded

Twisted Pair (UTP) wire. However, cable quality largely determines maximum link length. If you use high quality, low attenuation cable, you can achieve link lengths of up to 200 meters. Cable delay limits the maximum link length to 200 meters.

NOTE

Losses introduced by connections at punch-down blocks and other equipment reduce total segment length. For each connector or patch panel in the link, subtract 12 meters from the total length of the cable.

8H02-16 User’s Guide 2-1

Chapter 2: Network Requirements

Impedance

Cabletron Systems 10BASE-T twisted pair products work on twisted pair cable with 75 to 165 ohms impedance. UTP cables typically have an impedance from 85 to 110 ohms. Shielded twisted pair cables, such as

IBM Type 1 cable with an impedance of 150 ohms may also be used.

Temperature

Multi-pair PVC 24 AWG telephone cables typically have an attenuation of approximately 8–10 dB/100 m at 20

°

C (68

°

F). The attenuation of PVC insulated cable varies significantly with temperature. At temperatures greater than 40

°

C (104

°

F), use plenum-rated cable to ensure that attenuation remains within specification.

2.1.2

100BASE-TX Twisted Pair Network

The 8H02-16 with an FE-100TX installed in ports 15 or 16 provides an

RJ45 connection that supports UTP cabling. The device at the other end of the twisted pair segment must meet IEEE 802.3u 100BASE-TX specifications for the devices to operate at 100 Mbps. Use Category 5

UTP cabling for networks operating at 100 Mbps. Use Category 3, 4, or 5

UTP cabling for networks operating at 10 Mbps.

NOTE

The 8H02-16 with an FE-100TX installed is capable of operating at either 10 or 100 Mbps. The FE-100TX senses the speed of the other device and adjusts its speed accordingly.

When connecting a 100BASE-TX twisted pair segment to port 15 or 16 with an FE-100TX interface module, the network must meet the following requirements:

Length

The IEEE 802.3u standard for 100BASE-TX requires that 100BASE-TX devices be capable of transmitting over a 100 meter (328 foot) link using

Category 5 UTP cable.

The IEEE 802.3 standard for 10BASE-T requires that 10BASE-T devices be capable of transmitting over a 100 meter (328 foot) link using

Category 3, 4, or 5 UTP cable.

2-2 8H02-16 User’s Guide

Network Requirements

Propagation Delay

Propagation delay is the amount of time it takes data to travel from the sending device to the receiving device.

Total propagation delay allowed for a 100BASE-TX (100 Mbps) network is 256 bit times or 2.56 microseconds (2.56

µ s). If the total propagation delay between any two nodes on a 100BASE-TX network exceeds

2.56

µ s, then use bridges or other devices to further segment the network.

Total propagation delay allowed for a 10BASE-T (10 Mbps) network is

256 bit times or 25.6

µ s. If the total propagation delay between any two nodes on a 10BASE-T network exceeds 25.6


Temperature

The attenuation of PVC insulated cable varies significantly with temperature. At temperatures greater than 40

°

C (104

°

F), use plenum rated cables to ensure that cable attenuation remains within specification.

2.1.3

100BASE-FX Fiber Optic Network

Ports 15 and 16 of the 8H02-16 support the Cabletron Systems FE-100FX fiber optic interface module. The FE-100FX meets the IEEE 802.3u standard. When connecting a fiber optic segment to the 8H02-16, the network must meet the following requirements:

Cable Loss

Test the fiber optic cable with a fiber optic attenuation test set adjusted for an 850 nm wavelength. This test verifies that the signal loss is within an acceptable level. The maximum loss for a multimode cable is 11.0 dB.

Fiber Optic Budget and Propagation Delay

Determine the maximum fiber optic cable length by calculating the fiber optic budget delay and total network propagation before fiber optic cable runs are incorporated in any network design.

Fiber optic budget is the combination of the optical loss due to the fiber optic cable, in-line splices, and fiber optic connectors.

8H02-16 User’s Guide 2-3

Chapter 2: Network Requirements

Propagation delay (collision delay) is the amount of time it takes data to travel from the sending device to the receiving device. Total propagation delay allowed for the entire network is 256 bit times (2.56

µ s). If the total propagation delay between any two nodes on the network exceeds

2.56


2.2

100BASE-TX NETWORK CABLE LENGTHS

This section details the maximum network cable lengths specified by the

IEEE 802.3u standard. As stated in the previous sections, the physical size of the network is limited primarily by propagation delay. The total propagation delay cannot exceed 256 bit times or 2.56

µ s.

A 100BASE-TX/FX network might use all copper (UTP) links, all fiber links or a combination of both. The maximum length of any segment is determined by the types and combination of links and by the type of repeater (if any) between segments. IEEE 802.3u standards specify two repeater classes (Class 1 and Class 2) and the maximum cable lengths for each media type.

If this device is being installed in a 100BASE-TX/FX environment with repeaters, use the repeater instruction manual to determine the maximum cable lengths when laying out your network.

UTP Maximum Cable Lengths

An Unshielded Twisted Pair copper segment in a 100BASE-TX environment may be no more than 100 meters in length.

!

3.5.2

Connecting a UTP Segment to the FE-100TX

An FE-100-TX installed in port slot 15 and/or 16 is often used to provide a connection between the 8H02-16 and a bridge, router, or switch.

Usually, in this configuration, a “straight-through” cable is used and the

Fast Ethernet Interface Module crossover switch shown in Figure 3-7 is

set to “not crossed over.”

Normally, when connecting devices to like devices, crossing over of the transmit and receive pairs must occur. Before connecting a segment to the

FE-100TX, check each end of the segment to determine if the wires have been crossed over for the proper connection.

A schematic of a crossover cable is shown in Figure 3-6. If the wires do

not cross over, use the switch on the FE-100TX to internally cross over

the RJ45 port. Figure 3-7 shows how to properly set the FE-100TX

crossover switch.

• With a 100Base-TX interface: Unknown, 10Base-T, 10Base-TFD

(full duplex), 100Base-TX, or 100Base-TXFD (full duplex).

Desired Operational Mode (Selectable)

This field allows the user to select the desired operational mode for an interface in port 15 or 16. The field toggles between 100Base-FX and

100Base-FXFD (full duplex) when an FE-100FX is installed.

Section 6.14.1 describes how to configure a port with an FE-100FX.

6-40 8H02-16 User’s Guide


NOTE

In normal operation, the port with an FE-100TX installed automatically establishes a link with the device at the other end of the segment without requiring user setup. However, Local

Management provides the user with the option of manually configuring that port.

If an FE-100TX is installed, the field steps to Auto-Negotiation,

10Base-T, 10Base-TFD (full duplex), 100Base-TX, and 100Base-TXFD

(full duplex). In normal operation, the port with an FE-100TX installed is capable of auto-negotiating the operational mode and no further user

setup is required. Section 6.14.3 describes how to configure an

FE-100TX.

Advertised Ability (Selectable)

During auto-negotiation, the FE-100TX “tells” the device at the other end of the segment what its capabilities are. The capabilities of a port (15 or

16) with an FE-100TX installed are 10Base-T, 10Base-TFD (full duplex mode), 100Base-TX and 100Base-TXFD (full duplex mode). In normal operation, with all capabilities enabled, the FE-100TX “advertises” that it has the ability to operate in any mode. The Network Manager may choose to set up the port so that only a portion of the available capabilities are advertised and the others are disabled. For example, only 100Base-TX and 100Base-TXFD might be enabled so that only devices that operate at

100 Mbps can communicate with that port.

6.14.1

Configuring an FE-100FX in Port 15 or 16

When an FE-100FX is installed in port 15 or 16, it must be manually set to operate in the same technology as the device at the other end of the

connected segment. Section 6.14.2 provides instructions for manually

configuring the port with an FE-100FX interface.

The message “SAVED OK” appears and Local Management saves the changes to memory.

6.14.3

Configuring an FE-100TX in Port 15 or 16

In normal operation, a port (15 or 16) with an FE-100TX interface automatically establishes a link with the device at the other end of the

segment and no user setup is required. Section 6.14.4 and Section 6.14.5

provide instructions for manually configuring the port with an FE-100TX installed.

6.14.4

Setting the FE-100TX Operational Mode

Use this field to set the active technology. This field steps between

Auto-Negotiation, 10Base-T, 10Base-TFD (full duplex), 100Base-TX, and 100Base-TXFD (full duplex). If Auto-Negotiation is selected, the

FE-100TX automatically sets the active technology. To manually set the active technology through Local Management, proceed as follows:

1. Use the arrow keys to highlight the Desired Operational Mode field.

2. Use the SPACE bar to select the desired mode. Press ENTER. If any mode other than Auto-Negotiation is selected, the port only operates in the chosen mode and auto-negotiation is disabled.

arp:

Syntax:

Description: arp <options>

The arp command provides access to the ARP

(Address Resolution Protocol) cache, enabling you to view cache data, delete entries, or add a static route. Super-User access is required to delete an entry or add a static route.

Each ARP cache entry lists the network

interface that the device is connected to, the device’s network address or IP address, the device’s physical address or MAC address, and the media type of connection to the device.

Media types are displayed as numbers, which stand for the following states:

1 - Other

2 - Invalid entry (cannot ping device, timed out, etc.)

3 - Dynamic route entry

4 - Static route entry (not subject to change)

8H02-16 User’s Guide 6-59


You can specify the arp command without options, or with one of the following options:

Options: -a View cache data

-d Delete an IP address entry. Requires additional arguments: <Interface Number> <IP address>

-s Adds a static entry. Requires additional arguments: <Interface Number> <IP address>

(i.e., moving the switch from one position to the other) clears download information from NVRAM and forces the 8H02-16 to download a new image file from a BootP server.

After changing the position of switch 6, DO NOT reapply power to the 8H02-16 until there is a station acting as a BootP server, which contains the image file.

After changing the position of switch 6 and restarting the 8H02-16, the

8H02-16 requests a new image download until it either receives a new image or the RESET button on the front panel is pressed. When the

RESET button is pressed, the 8H02-16 continues trying to contact a

BootP server, but will time out in approximately one minute. If the

8H02-16 times out, the image is downloaded from its FLASH memory.

• Switch 7 - Clear NVRAM. Changing the position of this switch resets

NVRAM on either the next power up or the next operation of the front panel RESET switch. All user-entered parameters such as the IP address and Community Names are replaced with the 8H02-16

“Default” configuration settings.

• Switch 8 - Password Defaults. Changing the position of this switch clears user-entered passwords stored in NVRAM, and restores the default passwords. Once the 8H02-16 is reset, the passwords can either be reentered or the default passwords (Public and ENTER or

RETURN) may be used.

NOTE

Do not change the position of switch 8 unless it is necessary to reset the 8H02-16 Super-User configured passwords to their factory default settings.

The Fast Ethernet Interface Module and the 8H02-16 are sensitive to static discharges. Use an antistatic wrist strap and observe all static precautions during this procedure. Failure to do so could damage the module or the 8H02-16.

1. Remove the chassis cover as described in Section C.2.

2. Remove the coverplate from the port slot where the Fast Ethernet

Interface Module will be installed.


Installing Optional Fast Ethernet Interface Modules

TIP

When installing Fast Ethernet Interface Modules in both port slots 15 and 16, remove the coverplates from both slot openings. In the following instructions, the optional module is shown being installed in port slot 16.
