If you are not replacing the back up power supply being removed, be sure to install a blank cover panel 
(supplied with your switch) over the empty power supply bay. To install a blank cover panel, follow the 
steps below.

1 Place the blank cover panel over the empty power supply bay and insert two Phillips screws (also 
supplied with the switch) through the panel and into the threaded holes in the chassis. 

2 Once the screws are inserted, fasten the panel to the chassis by tightening the screws. Be sure not to 
overtighten the screws.

The switch constantly monitors primary and back up power supply operation. If either power supply unex-
pectedly shuts down, the switch sends out a trap to the user and the PS1 and/or PS2 LEDs on the chassis 
front panel turn amber.

Note. For detailed LED information, including the PS1 and PS2 LEDs, refer to 

To check the number of power supplies currently operating, and the status of each power supply, use the 

 command. For example:

installed in the chassis.

Note. For information on viewing primary and back up power supply status in a stacked configuration,
