Figure 1-13. Stack Down Configuration Example

Certain network management station (NMS) applications assume a stack-down configuration for the graphical user interface (GUI) that represents the stack (see Figure 1-13). For this reason, Nortel Networks recommends that you always configure the top unit in the stack as the base unit.

In any stack configuration, the following applies:

•When you apply power to the stack, the base unit initializes and the entire stack powers up as a single logical unit within 30 seconds.

•You can attach an RS-232 communications cable to the Console/Comm port of any switch in the stack.
