Stacking configurations

Cascade up
In a cascade up (stack up) configuration, the base unit is physically the top
unit in the stack. The cable connected to the Cascade Down connector
of the base unit terminates in the Cascade Up connector physically at
the bottom of the stack. This next unit is designated Unit 2. The stack is
wired upward through the units and the system continues to number in this
manner throughout the stack. In this configuration, the base unit discovers
the stack in a cascade up (stack up) direction. The following illustration
demonstrates a typical cascade up (stack up) configuration.

Note: Because many network management software packages use a
cascade down (stack down) configuration, Nortel recommends that you
use a cascade down configuration. (See
