Chapter 9 Configuring Catalyst 3750-X StackPower
Configuring Stack Power
This is an example of setting the stack power mode for the stack named power1 to redundant power
mode. The largest power supply in the stack is removed from the power budget and used as a backup in
case of power supply failure.
mode. The largest power supply in the stack is removed from the power budget and used as a backup in
case of power supply failure.
Switch(config)# stack-power stack power1
Switch(config-stackpower)# mode redundant
Switch(config-stackpower)# exit
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.
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
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.
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.
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.
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.
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.
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

Verify your entries.
Step 9
