supply fails.

Command
Step 1 configure terminal
Step 2 power-supply dual
Step 3

Step 4 show alarm settings
Step 5 copy running-config startup-config (Optional) Save your entries in the configuration file.
Use the no power-supply dual command to disable this alarm by setting the switch back to single power
mode operation.

Setting the Power Supply Alarm Options

Use the alarm facility power-supply global configuration command to associate the power supply
alarm to a relay. You can also configure all alarms and traps associated with the power supply alarm to
be sent to syslog and the SNMP server.
Beginning in privileged EXEC mode, follow these steps to associate the power supply alarm to a relay:
