Chapter 1 Configuring Catalyst 3750-X StackPower
For information about configuring the XPS 2000, see the configuration notes on Cisco.com:

Note A stack power member switch that does not have a PSU connected in Slot A or Slot B might fail during
a Cisco IOS upgrade.
The workaround is to ensure that each stack member has at least one PSU connected. Alternatively, you
can download and install the Cisco IOS image using the archive download-sw /force-ucode-reload
privileged EXEC command.
Configuring Power Stack Parameters
Beginning in privileged EXEC mode, follow these steps to configure a power stack:
Command
Step 1 configure terminal
Step 2 stack-power stack power stack name
Step 3 mode {power-sharing | redundant} [strict] Set the operating mode for the power stack:
Step 4
end
Step 5
show stack-power
Step 6 copy running-config startup-config
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.
Switch(config)# stack-power stack power1
Switch(config-stackpower)# mode redundant
Switch(config-stackpower)# exit
OL-25303-03
Purpose
Enter global configuration mode.
Enter the stack power stack name and enter power stack
configuration mode. The name can be up to 31 characters.
power-sharing—The input power from all switches in the
•
power stack can be used for loads, and the total available power
appears as one huge power supply. This is the default.
redundant—The largest power supply is removed from the
•
power pool to be used as backup power in case one of the other
power supplies fails. This is the recommended mode if enough
power is available in the system.
• strict—(Optional) Configures the power stack mode to run a
strict power budget. The stack power needs cannot exceed the
available power. The default is non-strict.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
