Overview on page 161
Installing the External Power System on page 163
The Extreme External Power System (EPS) allows you to add a redundant power supply to the Summit
X450 switch to protect against a power supply failure. The EPS consists of a tray (EPS-T) that holds one
or two EPS-160 power supplies. Each EPS-160 power supply provides one-to-one redundancy to an
attached Summit X450 switch.
The EPS-160 power supply installs into an existing EPS-T rack-mountable chassis. The EPS can be
ordered with one or two EPS-160 power supplies already installed. You can order an additional power
supply later from your Extreme Networks reseller.
Table 24 lists the specifications for each EPS-160 power supply installed in the EPS-T. Power supply
specifications along with compliance information is also available from the Extreme website.
Each individual EPS-160 power supply ships with an AC cord for use in the USA and a special
redundant power supply cable.
