3. Connect an appropriate AC power cord to the AC connector on each unit.
Note
An AC power cord is not provided with the EPS-160 unit. For information about selecting a
power cord, see Power Cord Requirements for AC-Powered Switches and AC Power
Supplies on page 653.
The Power LED on the front of the EPS-160 should light solid green to indicate that it is ready.
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 table.
Note
An AC power cord is not provided with the EPS-500 unit. See Power Cord Requirements for
AC-Powered Switches and AC Power Supplies on page 653 for information about selecting a
power cord.
Rack-mounting the EPS-500 Power Supply
Caution
When you install an EPS-500 in an equipment rack, make sure that the air vents are not
restricted. Allow for elevated ambient operating temperatures when the unit is installed
adjacent to other equipment. To avoid hazardous conditions due to uneven mechanical
loading, make sure that the equipment is mounted properly in the equipment rack.
Caution
Do not use the rack-mount brackets to suspend the EPS-500 from under a table or desk, or to
attach the unit to a wall.
To rack-mount an EPS-500 in a 19-inch rack, follow these steps:
1. Place the EPS-500 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 EPS-500 (see Figure 303).
