Stack configuration

The Nortel Ethernet Routing Switch 2500 series provides the capability for intelligent fail-safe resilient stacking of up to eight units in a single switch stack. This provides uninterrupted connectivity of up to 400 user ports in a virtual switch managed as a single unit.

ATTENTION

All ERS 2500 series switches must be running software release 4.1 before being connected in a stack configuration.

To set up a stack, do the following:

Step Action

1Power down all switches.

2Set the Unit Select switch at the rear of the non-base units to the off position.

3Plug all stack cables in to the rear RJ-45 cascade ports and ensure the cables are connected from Cascade Down on the first unit to Cascade Up on the second unit and so on. The last unit in the stack must be connected back to the first unit for full stack resiliency. Ensure all the cascade cables are properly connected.

4Power up all the switches in the stack starting with the Base unit.

ATTENTION

In a mixed stack of 2526T, 2526T-PWR, 2550T, and 2550T-PWR, any switch can act as the Base unit.

—End—

ATTENTION

The rear ports must be operating Stacking Mode before adding a switch into a stack.
