Connecting Power
When the stack is initially powered up, the software
automatically assigns unit numbers to the units (the
individual switches in the stack). The unit numbers
correspond to the physical stack power up/initialization
sequence, beginning with the base unit as unit 1.
The stack initialization sequence takes approximately 30
seconds for completion. If any switch in the stack
configuration does not power up or initialize within 15
seconds, it is assigned a unit number that may be out of
sequence with the stacking order.
If this happens, you can renumber the units when you
perform the initial setup of the stack as described in your
switch’s User Guide.
Power up the stack configuration as follows:
1. Plug the AC power cord for each switch in the
stack configuration into the AC power receptacle
on each switch’s back panel.
Note:
Nortel Networks recommends that you connect
all of the switch AC power cords to one or two AC
power strips that can apply power to all of the switches
simultaneously.
