Installing the External Power System

The Extreme External Power System (EPS) allows you to add a redundant power supply to the
Summit 400 switch to protect against a power supply failure. It consists of a tray (EPS-T) that holds one
or two EPS-160 power supplies. Each EPS-160 provides one-to-one redundancy to an attached Extreme
switch. Please check the Extreme website or with your local sales representative for a list of compatible
Extreme switches.
The EPS can be ordered with one or two EPS-160 power supplies. You can order an additional EPS-160
to add to an EPS system. If you do not already have an EPS-T, you can order one from your sales
representative. The EPS-160 installs into an existing EPS-T rack-mountable chassis.Each individual
EPS-160 ships with an AC cord for use in the USA and a special redundant power supply cable.
CAUTION
The Extreme External Power System must only be installed or removed by trained service personnel in
accordance with the installation instructions. Before servicing this system, please read the safety
information provided in. Not following these precautions can result in equipment damage or shock.
Table 11 lists the specifications for each EPS-160 installed in the External Power System. Power supply
specifications along with compliance information is also available from the Extreme website.
