information about selecting a power cord.

Removing an EPS-160 Power Supply from an EPS-T
To remove an EPS-160 power supply from an EPS-T:
1 Disconnect the AC power by removing the plug from the wall.
2 Disconnect the AC power cord from the EPS-160.
3 Disconnect the redundant power cord from the EPS-160.
4 Loosen the captive retaining screws on the front of the EPS-160 and slide it out of the EPS-T.
Installing an EPS-LD External Power Supply
The EPS-LD power supply can be mounted in a rack or placed free-standing on a tabletop. You can
position the EPS-LD facing either the front or the back of the rack. For this reason, each unit has two
sets of mounting holes on each side. Extreme Networks recommends that you position the EPS-LD so
that the power output connectors on the EPS-LD unit are on the same side as the external connector on
the connecting switch.
CAUTION
Do not use the rack-mount brackets to suspend the EPS-LD from under a table or desk, or to attach the unit to a
wall.
NOTE
An AC power cord is not provided with the EPS-LD power supply. See “Selecting Power Supply Cords” on page 218
for information about selecting a power cord.
