Configuring Cisco StackPower
Configuring Power Stack Switch Power Parameters
Beginning in privileged EXEC mode, follow these steps to configure a switch in a power stack:
This is an example of setting the switch stack power parameters for switch 3 in the stack that is connected
to the power stack with the stack ID power2. If load-shedding becomes necessary, switches and powered
devices in the power stack with the higher numbers are shut down first, with shutdown proceeding in
order.
Switch(config)# stack-power switch 3
Switch(config-switch-stackpower)# stack power2
Switch(config-switch-stackpower)# power-priority switch 5
Switch(config-switch-stackpower)# power-priority high 12
Switch(config-switch-stackpower)# power-priority low 20
Switch(config-switch-stackpower)# exit
Switch(config-stackpower)# exit
Note Entering the write erase and reload privileged EXEC commands down not change the power priority or
power mode non-default configuration saved in the switch flash memory.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
stack-power switch switch-number Enter the stack member number of the switch in the power stack and
enter switch stack power configuration mode. The range is from 1
to 9.
Note Only four switches can belong to the same power stack.
Step 3
stack [power-stack-name] Enter the name of the power stack to which the switch belongs. The
name can be up to 31 characters. If you do not enter a name and no
other switches in the power stack have a name configured, a
power-stack name is automatically generated.
Step 4
power-priority switch value Set the power priority of the switch. The range is from 1 to 27. This
value must be lower than the value set for the low and high-priority
ports.
Step 5
power-priority high value Set the power priority of the PoE ports on the switch that are
configured as high-priority ports. The range is from 1 to 27, with 1
as the highest priority. The high value must be lower than the value
set for the low-priority ports and higher than the value set for the
switch.
Step 6
power-priority low value Set the power priority of the PoE ports on the switch that are
configured as low-priority ports. The range is from 1 to 27. This
value must be higher than the value set for the low-priority ports
and the value set for the switch.
Step 7
end Return to privileged EXEC mode.
Step 8
show stack-power Verify your entries.
Step 9
copy running-config startup-config (Optional) Save your entries in the configuration file.
