Redundant Cascade Stacking - Avaya Ethernet Routing Switch 3600 Series Manual

Installing ERS 3600 in an equipment rack
Cascade up
In a cascade up (stack up) configuration, the base unit is physically located as 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 located 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 shows a cascade up (stack up) configuration.

Note:
Return cable length might vary depending on unit spacing. Ensure you order the proper length
return cable to provide adequate strain relief.

Redundant cascade stacking

The 3600 Series switches allow a stack of up to eight units in a 3600 Series stack. If any single unit
fails or if a cable is accidently disconnected, other units in the stack remain operational without
interruption.
