PoE Configurations (OS6855-14 only)
OS6855-14 switches using PoE also require a second power supply. This second power supply is a PoE-
specific unit included with your Alcatel-Lucent product shipment.
Note. To distinguish PoE power supplies from standard system power supplies, note that PoE supplies
have both a long and short connector cable hard-wired into the power supply brick, while standard system
power supplies have only a single, long connector cable.
For this configuration, plug the longer connector cable from the PoE power supply into the PoE1 port on
the rear panel of the chassis.
Next, connect the shorter PoE connector cable to the female AC connector on the system power supply
installed at step 2.
When complete, continue to step 5.
Redundant Chassis Power with PoE (OS6855-14 only)
For OS6855-14 switches using redundant chassis power in addition to PoE, a total of four power supplies
are required.
For this configuration, plug a second Alcatel-Lucent-provided system power supply into the PS2 port on
the rear panel of the chassis.
Next, plug the longer connector cable from one of the Alcatel-Lucent-provided PoE power supplies into
the PoE1 port on the rear panel of the chassis, then connect the shorter connector cable to the female AC
connector on the system power supply installed at step 2.
Plug the longer connector cable from the second PoE power supply into the PoE2 port on the rear panel of
the chassis, then connect the shorter cable to the female AC connector on the remaining system power
supply.
When complete, continue to step 5.
