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.
