Removing a Link Module
If there are no empt y slots in your BN plat form, you must remo ve a link mod ule to
install the ATM link module. Wh en r ep lac in g a configured lin k module, you must
delete all configured circuits (ports) on the slot so the BN platform software can
properly configure the new link module.

Refer to Configuring Routers if you use router software or Administration Guide
if you use BayStream software for instructions on editing a configuration file and
deleting circuits.
The BN 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.

Installing ATM Link Modules and Routing Engines in BN Platforms
Removing a link module with the power on distrupts the services that slot
provides. Howev er, after the slot fails to recei v e pa cke ts , the oth er lin k 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.
Caution:
Electrostatic discharge can damage hardware. Always use an
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 ARE DS-3 link module (Order No. AG13110114) and the ARE E-3 link
module (Order No. AG13110115) contain user-configurable jumper settings.
Note: The other ATM link modules and the ARE processor module do not
contain user-configurable jumpers or switches. Changing the jumper settings
on these modules can jeopardize module functioning.

The jumper locations and settings on the ARE DS-3 and the ARE E-3 link
modules are identical.
