Figure 62: Removing the Summit 300-48 power supply

If you are not going to install a replacement power supply, cover the power supply bay with the 
blank cover plate that was originally supplied with the switch.

If you are replacing a power supply, follow the installation instructions in “Installing an Internal 
600-Watt Power Supply” on page 122.

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.
