52 Installing the Nortel Ethernet Routing Switch
Note: To create a stack connection, order the appropriate Nortel
Ethernet Routing Switch 5500 Series cascade cables to ensure fail-safe
stacking. These cables are not provided with the switch.
The following illustration demonstrates the proper crossover connection
configuration. Failure to use this configuration can result in loss of
connectivity.

Stack configuration
Switches in a stack must be configured to perform as either the base or
non-base units in the stack. The base unit performs important tasks during
stack functioning and it is important that only one switch be designated
as base.
These stack configuration tasks can be performed using either the User
Interface (UI) button on the front panel of the switch or the Unit Select switch
on the back. The following sections describe the procedures for performing
these tasks.
Stack configuration using the UI button
The UI button can be used to perform a number of stack configuration tasks.
This section describes the following tasks:
• "Setting the Base Unit" (page 53)
•
"Setting the Non-Base Units" (page 53)
• "Resetting the stack" (page 54)
