OmniSwitch 6600 with 8 stackable switches show up. Notice that the switch with ID 1 is the primary
CMM and the switch with ID of 2 is the secondary. All the switch also show up as NI because each switch
has a CPU and is also a NI.
To verify the stacking topology, use the following command:
-> show stack topology
Link A Link A Link A Link B Link B Link B
NI Role State RemoteNI RemoteLink State RemoteNI RemoteLink

1 PRIMARY ACTIVE 8 51 ACTIVE 2 52
2 SECONDARY ACTIVE 3 27 ACTIVE 1 52
3 IDLE ACTIVE 2 51 ACTIVE 4 52
4 IDLE ACTIVE 5 51 ACTIVE 3 28
5 IDLE ACTIVE 4 51 ACTIVE 6 52
6 IDLE ACTIVE 7 51 ACTIVE 5 52
7 IDLE ACTIVE 6 51 ACTIVE 8 52
8 IDLE ACTIVE 1 51 ACTIVE 7 2
The above command shows the stacking topology. Switch 1 is the primary connected to Switch 8 on port
51 and Switch 2 on port 52. The state of CPUs for all the switches in the stack is shown by the output of
this command.
2 Verify the power supply (or supplies).
OmniSwitch 7700/7800/8800
Omni Switch 7/8XXX has build-in mechanism to power off the modules if the power supply is not
enough. Switching off a power supply in a chassis which does not have redundant power supply will result
in power off of the modules. Make sure that there is no power involvement.
Check the power supply status, using the command:
-> show power supply 1
