Removing an EPS-LD
To remove an EPS-LD power supply:
1 Disconnect the AC power by removing the plug from the wall.
2 Disconnect the AC power cord from the EPS-LD unit.
3 Disconnect the cord between the Extreme switch and the EPS-LD.
4 Remove the screws from the EPS-LD mounting brackets.
5 Slide the EPS-LD out of the rack.
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.
NOTE
If you are using the EPS-500 outside of North America, the input power cord must utilize an IEC320-C13 input
connector and the appropriate power input plug for the country in which you are operating the unit. The input power
cord must be at least 18 AWG copper wire and it must be less than 10 feet (3 m) long.
Rack-mounting an EPS-500 Power Supply
CAUTION
When installing an EPS-500 in a rack system, 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 rack
system.
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 each EPS-500:
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 56).
b Insert the provided screws and fully tighten the screws using a screwdriver.
