OmniSwitch 6800 Series Hardware Users Guide June 2007 page 2-53
Viewing Primary and Backup Power Supply
Status
The switch constantly monitors primary and backup power supply operation. If either the primary or
backup power source unexpectedly shuts down, the switch sends out a notification to the user. In addition,
the power LED on the chassis front panel and the LED on the backup power supply front panel (if
installed) display solid amber.
Note. For detailed OS6800-24 and OS6800-48 LED information, refer to “Status LEDs” on page 2-13 .
To check the number of power supplies currently operating, and the status of each power supply, use the
show power command. For example:
-> show power
Power Supplies in chassis 1
PS Operational Status
---------+-------------------
PS-1 48V UP
PS-2 48V NOT PRESENT
The primary (i.e., factory-installed) power supply is listed as PS-1 in the show power command output.
The backup power supply is listed as PS-2. In the example above, there is no backup power supply
installed.
Note. For information on viewing primary and backup power supply status in a stacked configuration,
refer to
page 2-53 .
Viewing Power Supply Status for Stacked Configurations
When entering the show power command on the primary switch in a stacked configuration, you can either
enter only the show power syntax or you can specify a specific slot number. For more information, refer
to the examples below.
A Slot Number is Specified
If you specify a slot number after the command syntax, power supply information for only the correspond-
ing switch displays. For example:
Power Supplies in chassis 2
PS Operational Status
---------+-------------------
PS-1 48V UP
PS-2 48V NOT PRESENT
In the example above, power supply status for the switch operating in slot 2 displays. No backup power
supply is installed—or the backup power supply is powered off.
