Extreme Networks 17001 manual Installing an EPS-500 External Power Supply Unit, Removing an EPS-LD

Installing Summit External Power Supplies

Connecting the EPS-LD to Power

An AC input power cord is not provided with the EPS-LD. For information about power cord requirements, see “Selecting Power Supply Cords” on page 218.

Make sure the EPS-LD is connected to the switch before you connect the AC power.

CAUTION

The EPS-LD does not have a switch for turning the unit on and off. You disconnect power to the EPS-LD by removing the plug from the electrical outlet. Make sure that this connection is easily accessible.

To connect the EPS-LD to power:

1Connect the AC input power cord to the AC connector on the EPS-LD.

2Connect the other end of the AC cord to the electrical outlet. Make sure the electrical outlet is properly grounded.

The Power LED on the front of the EPS-LD turns solid green to indicate that it is ready.

Table 28 shows the LED meanings for the EPS-LD power supply.

Removing an EPS-LD

To remove an EPS-LD power supply:

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

2Disconnect the AC power cord from the EPS-LD unit.

3Disconnect the cord between the Extreme switch and the EPS-LD.

4Remove the screws from the EPS-LD mounting brackets.

Installing an EPS-500 External Power Supply Unit

You can position the EPS-500 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- 500 unit so that the power output connectors of the EPS-500 unit are on the same side as the external connector on the connecting switch.

The EPS-500 unit can be mounted in a rack or placed free-standing on a tabletop.
