EPS-LD External Power Supply Unit

The Extreme Networks EPS-LD External Power Supply Unit can be added as a redundant power supply
to the Summit X450a-24t or Summit X450e-24p switch. When attached to the Summit X450e-24p, the
EPS-LD provides 465 W total power with 375 W dedicated for PoE applications.

Installing an EPS-LD

The external power supply box contains the following items:
One EPS-LD unit
●
Mounting hardware, including screws
●
One AC power cord (for use in North America)
●
One redundant power cord (1 meter long) for connecting the power supply to the switch
●
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.
The EPS-LD unit can be mounted in a rack or placed free-standing on a tabletop. You can mount the
EPS-LD facing either the front or the back of the rack. For this reason, each unit has two sets of
mounting holes, two on each end. Mount the EPS-LD so that the unit's output connectors 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.

Rack-mounting the EPS-LD

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 install the EPS-LD, you need the following tools and materials:
Electrostatic strap
●
#1 Phillips screwdriver
●
