Redundant Chassis Power with PoE (OS6855-14 only)
For OS6855-14 switches using redundant chassis power with PoE, an additional power supply tray is
required. This power supply tray is included with all shipments for which redundant chassis power and
PoE have been specified as requirements. To install the second power supply tray, see steps 11 through 15
below.
11 Insert the two tabs at the base of the tray into the slots provided at the bottom-rear portion of the switch
chassis.
12 Be sure that the two holes in the tray are aligned with the threaded holes in the rear panel of the
chassis and secure the tray to the switch using the two attachment screws (provided).
13 Place the PoE power supplies into the power supply tray with the connector cables facing forward.
14 Position the power supply retaining strap over the PoE power supplies. Insert the retaining strap’s tabs
into the notches located on the left and right sides of each power supply. Again, be sure that the tabs are
completely inserted in the power supply notches and that the end flanges of the retaining strap fit inside
the walls of the power supply tray.
15 Secure the retaining strap to the power supply tray using the attachment screws (provided).
16 Plug the power supply cord into the female AC connector located on the back of each power supply
brick.
Note. For PoE configurations, the system power supplies will already have power cords plugged into the
AC connectors. Plug the power supply cord into the female AC connector in each PoE power supply, as
applicable.
Note. Use only the power cord(s) supplied with your OmniSwitch. The power supply’s female AC
connector includes a small notch that restricts the installation of many standard, non-OS6855 AC power
cords. Never force the power cord into the female AC connector.
