EPS-150DC External Power Module (with EPS-T2)

The EPS-150DC External Power Module (Model 10909) is a modular power supply for use in the EPS-T2 External Power System Tray.

When this power supply is used with one of the listed Summit switches, the internal and external power supplies 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-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 switch. You must install the EPS-150DC power supply in the EPS-T2 tray.

The front panel of the EPS-150DC unit has a green LED to indicate operating status as shown in the following table.

Power LED	Meaning
Green, solid	The external power module is operating normally.
Off	The external power module is not connected.
