Configuring Switch 2000 TR in Stack
Head Unit
One of the unique characteristics of the Switch 2000
TR is its ability to be part of a stack. When installed as
members of a stack, up to 6 Switch 2000 TRs form
the equivalent of a switching chassis, managed using
the same IP address. All traffic, management, moni-
toring, and configuration tasks and inquiries operate
through the high-speed cascade interface located at
the rear of each unit. See Figure 3-1.
Configuration rules for the Switch 2000 TR are sim-
ple:
■
The head unit must have the lowest Unit ID
number in the stack.
■
The head unit should be at the bottom of the
stack.
■
It is recommended that each consecutive unit have
sequential Unit IDs.
■
To ensure redundancy each consecutive unit
should have the same IP address setting as the
head unit.

Cascade Connections
Cascade connectors must attach from the top con-
nector of bottom unit to the bottom connector of
next highest unit, up through the stack. See
Figure 3-2.
