EPS-160 External Power Module (with EPS-T)
The Extreme Networks EPS-160 External Power Module can be added as a redundant power supply to
the Summit X450-24t, X450-24x, X250e-24t, or X250e-48t switch. The entire EPS system 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 switch.
The EPS-160 power supply is installed in an EPS-T rack-mountable chassis. The EPS-T chassis can be
ordered with one or two EPS-160 power supplies already installed. You can also order an additional
power supply from your Extreme Networks reseller.
Each individual EPS-160 power supply is shipped with an AC cord for use in North America and a special redundant
power supply cord.
Table 39 shows the wire-to-pin connections for the connector on the rear panel of the EPS-160 power
supply.
Figure 217 shows the redundant power cord connector.
