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
An AC power cord is not provided with the EPS-LD power supply. See 
for information about selecting a power cord.
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.
