You can add a backup power supply to the chassis at any time without disturbing the switch’s network 
functions. You are not required to power down the switch.

Note. This section only applies to OmniSwitch 6624, 6648, and 6600-U24 switches.

Hot swapping a backup power supply refers to the action of replacing the unit while the switch is operat-
ing. Again, because it is a backup (i.e., redundant component), you are not required to power off the 
switch’s primary power source.

To add the optional backup power supply to the chassis, follow the steps below:

Anti-Static Warning. Before handling any component, free yourself of static by wearing a grounding 
strap, or by grounding yourself properly. Static discharge can damage the switch and the backup power 
supply.

1 Locate the backup power supply bay. The backup power supply bay is located at the switch’s rear 
panel. Refer to 

 for a view of the chassis rear panel.

2 If there is a blank cover panel installed at the backup power supply bay, uninstall it by removing the 
two Phillips attachment screws. After the attachment screws have been removed, carefully pry the blank 
cover panel out and away from the chassis. Set the cover panel and attachment screws aside.

3 To avoid attempting to install the backup power supply upside down, orient the unit as shown in the 
diagram below.
