Installation Guide

The EPS-T2 is a rack-mountable chassis or tray that holds one or two EPS-150DC power supplies. Each
EPS-150DC provides one-to-one redundancy to an attached Extreme Networks switch. You must install
the EPS-150DC power supply in the EPS-T2 tray.
Warning
Always be sure that the DC circuit is de-energized before connecting or disconnecting the DC
wiring harness at the DC power socket on the rear of the EPS-150DC unit, and before
connecting or disconnecting the redundant power cord between the switch and the
EPS-150DC unit.
Caution
Do not use the rack-mount brackets to suspend the EPS-T2 from under a table or desk, or to
attach the EPS-T2 to a wall.
Note
For centralized DC power connection, this product is intended to be installed in restricted
