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

If you are using the EPS-LD outside North America, the input power cord must have an IEC320-C14 connector and

the appropriate power input plug for the country in which you are operating. The cord must be 10 feet or less and at

least 16-gauge copper wire.

Rack-mounting the EPS-LD Power Supply

NOTE

When installing an EPS-LD in a rack, make sure air vents are not restricted. Allow for elevated ambient operating

temperatures when the EPS-LD is installed adjacent to other equipment. Be sure you mount the equipment in the

rack so that the load is evenly distributed.

To rack-mount each EPS-LD unit:

1 Place the EPS-LD unit upright on a stable surface, with the side you want to face to the front of the

switch toward you.

2 Remove the mounting bracket kit from the packaging.

3 Attach the mounting brackets as follows:

a Place a mounting bracket over the mounting holes on one side of the unit (see Figure 53).

b Insert the provided screws and fully tighten them using a screwdriver.
