Installing an External Power System for a Summit 400
Switch
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. Check the Extreme website or contact your local sales representative for a list of compatible
Extreme switches.
The external power system can be ordered with one or two EPS-160 power supplies. The EPS-160
installs into an existing EPS-T rack-mountable chassis. You can order an additional EPS-160 to add to an
installed system. If you do not already have an EPS-T, you can order one from your sales representative.
Each EPS-160 ships with an AC cord for use in the USA and a special redundant power supply cable.
The EPS-T can be mounted in a rack or placed free-standing on a tabletop.
CAUTION
Only trained service personnel should install or remove the Extreme External Power System, in
accordance with the installation instructions. Before servicing this system, please read the safety
information provided in Appendix A. Not following these precautions can result in equipment damage or
shock.
