EPS-150DC External Power Module (with EPS-T2)
This section describes the installation process for the Extreme Networks EPS-150DC (External Power
Module 10909) and specific safety requirements that must be adhered to when connecting an EPS-
150DC to a DC power source and to an Extreme Networks switch.
The EPS-150DC is a modular power supply for use in the External Power System Tray (EPS-T2). It
allows you to add a redundant power supply to compatible Extreme switches to protect against a
power supply failure. The EPS-T2 is a tray that holds one or two EPS-150DC power supplies. Each EPS-
150DC provides one-to-one redundancy to an attached Extreme switch. The EPS-150DC installs into an
EPS-T2 rack-mountable chassis.
The EPS-150DC is available for use with the Summit X450a-24tDC, Summit X450a-24xDC, or Summit X450a-
48tDC switch. When the one of these Summit switches is used with the EPS-150DC, the power supplies (internal
and redundant) are fully fault tolerant and load-sharing. If one power supply fails, the other power supply will
provide sufficient power to operate the switch.
The EPS-150DC unit is shipped with the following items in the box:
● One EPS-150DC unit
● Mounting hardware, including screws
● One DC wiring harness
● One EPS-150DC redundant power cord (for connecting to Summit switches)
For centralized DC power connection, this product is intended to be installed in restricted access locations
(dedicated equipment rooms, equipment closets, or the like) in accordance with Articles 110-16, 110-17, and 110-
18 of the National Electric Code, ANSI/NFPA 70.
