Connecting The Eps-500 Power Supply - Extreme Networks Summit X150 Series Hardware Installation Manual

Chapter 7: Installing Summit External Power Supplies
NOTE
Extreme Networks recommends that you position the EPS-500 so that the output connectors are on the
same side as the external connector on the connecting switch. If you position the EPS-500 with the connectors
facing in the opposite direction from the Summit switch connector, leave at least 1 U between the switch and
the EPS-500 through which to slide the power cords. Do not route the power cords around the equipment rack.

Connecting the EPS-500 Power Supply

CAUTION
Do not attach the AC power cord to the EPS-500 unit until the unit is properly grounded at the electrical
outlet and the redundant power cord is connected.
One end of the EPS-500 cord has a keyed connector to ensure correct alignment of the connector
(Figure 251). The key is a plastic tab on the connector housing that fits into the EPS-500 unit.
Figure 251: EPS-500 Redundant Power Cord with Connector Key
1 Connect the keyed end of the EPS-500 redundant power cord to the power supply unit (see
Figure 252).
2 Connect the other end of the redundant power cord to the Extreme switch.
The connector fits the slot in only one direction.
NOTE
If your switch was shipped with a metal cover plate over the redundant power input connector,
remove the cover.
WARNING!
The redundant power input connector on the rear of the switch contains high energy and is a burn
hazard. Use care when connecting the redundant power supply cord to the rear of the switch.
