Installing Power Supplies
OmniSwitch 6400 Series power supply can be installed in the following ways:
• As a primary or backup supply directly connected to the back of an OmniSwitch 6400 Series chassis.
See “Connecting a Power Supply to the Chassis” below for more information.
• As a primary or backup supply rack mounted directly above or below the switch and connected with a
cable. See “Connecting Chassis to Power Source” on page 3-18 for more information.
DC power supplies require additional installation steps. See “DC Power Specifications” on page 2-29 for
more information.
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 backup power
supply.

cable, refer to “Rack Mounting Power Supplies” on page 3-14.
