Removing an EPS-160 Power Supply from an EPS-T

To remove an EPS-160 power supply from an EPS-T:

1Disconnect the AC power by removing the plug from the wall.

2Disconnect the AC power cord from the EPS-160.

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.
