Connecting the EPS-160 Power Supply to the Switch
One end of the EPS-160 redundant power cord has a keyed connector to ensure correct alignment of the
connector (Figure 148). The key is a plastic tab on the cord connector housing that fits into the EPS-160
unit to ensure correct alignment of the connector.

CAUTION
Always connect the redundant power supply cord before you attach the AC power cord to the EPS-160 power supply.
To connect the EPS-160 power supply to the switch:
1 Connect the keyed end of the redundant power supply cord to the EPS-160 power supply (see
Figure 149).
2 Connect the other end of the redundant power supply cord to the Extreme switch (see Figure 149).
This connector end can only be inserted into the switch with the end marked TOP facing up.
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.
