Installing or Removing an External Power Supply 45019
(EPS-LD)
(EPS-LD)
The Extreme Networks External Power Supply 45019 (EPS-LD) provides additional power to switches
that support Power over Ethernet (PoE), such as the Summit 300-24 and Summit 400-24p. The EPS-LD
provides 465 W total power with 375 W dedicated for PoE applications. When attached to the Summit
300-24 or Summit 400-24p, the EPS-LD acts as a redundant power supply. The wattage is sufficient to
power all ports on the Summit 300-24 and Summit 400-24p models.

The external power supply box contains the following items:
•
One EPS-LD unit
•
Mounting hardware, including screws
•
One AC power cable for use in North America.
•
One EPS-LD cable (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.

Rack-mounting the EPS-LD unit
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 within the rack so that the load is evenly distributed.
