Installing a Back Up Power Supply
You can add a back up power supply to the chassis at any time without disturbing the switch’s network
functions. You are not required to power down the switch.
Hot Swapping
Hot swapping a back up power supply refers to the action of replacing the unit while the switch is operat-
ing. Again, because it is a back up (i.e., redundant component), you are not required to power off the
switch’s primary power source.
To add the optional back up power supply to the chassis, follow the steps below:
Anti-Static Warning. Before handling any components, free yourself of static by wearing a grounding
strap, or by grounding yourself properly. Static discharge can damage the switch and the back up power
supply.
1 Locate the back up power supply bay. The back up power supply bay is located at the switch’s rear
panel. Refer to page 2-12 for a view of the chassis rear panel.
2 If there is a blank cover panel installed at the back up 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 back up power supply upside down, orient the unit as shown in the
diagram below.
