Removing a Link Module
If there are no empty slots in your BN platform, you must remove a link module to
install the Sync/Ethernet link module. When replacing a configured link module,
you must delete all configured circuits (ports) on the slot so the BN platform
software can properly configure the new link module.

Installing Sync/Ethernet Link Modules in BN Platforms
The Backbone Node hot-swap feature allows you to remove or replace a link
module with the chassis power on or off.
Danger: Do not remove more than two adjacent modules with the power on.
When you remove a link module with the power on, the services that slot pro vides
become disrupted. After the slot f ails to receive packets, the other link modules in
the chassis resynchronize their routing tables and continue uninterrupted.
The procedure for removing a link module is the same for the BLN, BLN-2, and
BCN platforms:
1.
Disconnect any exterior cables from the link module.
2.
Attach an antistatic wrist strap.
BN platforms and link modules ship with an antistatic wrist strap. You must
wear one of these straps when accessing components on BN platforms. The
antistatic wrist strap directs the discharge of static electricity from your body
to the chassis, thereby avoiding discharge and possible damage to sensitive
electronic components.
1-4
Caution: Electrostatic discharge can damage hardware. Always use the
antistatic wrist strap when handling any component on your BN platform.
3.
Loosen the captive screw on each end of the module.
4.
Grasp the sides of the module and pull it out of the slot.
5.
Place the module in an antistatic protective bag.

Configuring Jumper Settings
The following Sync/Ethernet link modules contain at least one user-configurable

Before you install a Sync/Ethernet link module, make sure the jumper settings on
the link module match your configuration. The following sections describe only
the user-configurable jumper settings; changing the settings of any other jumpers
on the link module can jeopardize module functioning.

Complete the steps in this chapter to install the Sync/Ethernet link module in your
BLN, BLN-2, or BCN platform.
Inserting the Link Module
Install the link module in the BLN, BLN-2, or BCN platform as follows:
1.Attach an antistatic wrist strap.
Chapter 2
Installing the Link Module
BN platforms and link modules ship with an antistatic wrist strap. You must
wear one of these straps whenever you access components in a platform.
The antistatic wrist strap directs the discharge of static electricity from your
body to the chassis, thereby avoiding discharge and possible damage to
sensitive electronic components.
Caution: Electrostatic discharge can damage hardware. Always use the
antistatic wrist strap when handling any router components.
2.Slide the module into the appropriate slot, using the slot card guides.
Refer to Figure 1-1 (BLN), 1-2 (BLN-2), or 1-3 (BCN) for slot locations.
3.Insert the module until its connector panel touches the router back panel.
4.Secure the captive screw on each end of the module (Figure 2-1).

Checking Status Indicators
This chapter describes the status indicator lights (LEDs) on the Sync/Ethernet link
modules. Use the LEDs to verify that the link module is operating after
installation.
Note: We recommend that you issue the diags command to the associated
slot, using the Bay Networks Technician Interface, immediately after you
insert a link module. (Refer to Using Technician Interface Software if you use
router software or Troubleshooting and Testing if you use BayStream
software.) Otherwise, the link module FAIL LED will remain lit, indicating
that diagnostics have not run on the Intelligent Link Interface (ILI). However,

Appendix B
Requirements for European Operation
This appendix provides technical specifications and notes about operating the
following link modules in Europe.
The link modules are approved only for installation in a host, and with host
attachments, which are either type approved for such apparatus or, if supplied
after March 1, 1989, are marked with or supplied with a statement that the host is
supplied under the terms of General Approval No. NS/G/1234/J/100003.
Installation of the link modules in a BLN, BLN-2, or BCN platform will satisfy
the conditions stated in this appendix. The BLN, BLN-2, and BCN platforms are
supplied under the terms of General Approval NS/G/1234/J/100003.

The creepage distances apply to the normal office environment. When the local
environment within the host chassis is subject to conductive pollution or dry
nonconductive pollution that could become conductive due to condensation, the
creepage distances shown in parentheses in T

The clearance and creepage distance between adjacent points should be checked
as follows (Figure
