Installation Guide

3. Unplug the second EPS-600LS unit from its power source.
The internal power supply is already enabled and provides uninterrupted 370 watts of PoE power.
Note
After an EPS-600LS unit is disconnected from its power source, it may be removed from
the EPS-C. See Removing an EPS-600LS Power Module on page 468 for disconnection
and removal instructions.
4. Disconnect the EPS-C from the switch.
RPS-90 Redundant Power Supply
Tip
Extreme Redundant Power Supplies (RPS) do not support the ability for the RPS to be
connected to an operational switch. Connecting an RPS to an operational switch can have an
adverse eect on the switch. It is best practice that both the switch and the RPS be powered
down prior to cabling them together. Once the cabling is completed, turn on the RPS, then
turn on the switch.
The Extreme Networks RPS-90 (model 10948) is supported as a power source for the
ExtremeSwitching X440-G2-12t-10GE4 switch. It plugs into the RPS connector (coaxial barrel
connector) on the rear panel of the switch.
Note
Only the Extreme Networks RPS-90 RPS is supported for use with the X440-G2-12t-10GE4
switch. RPS-90 devices from other manufacturers are not supported.
The RPS-90 power supply has a C6-format AC power input connector. As a result, you will need to
obtain both a standard C13 AC power cord and a C5-to-C14 converter (Extreme Networks model
10947).
Note
The converter is not available in China. A special power cord is available for use with the
RPS-90 in China.
The RPS-90 cannot be mounted in a rack.

RPS-150XT Redundant Power Supply
Tip
Extreme Redundant Power Supplies (RPS) do not support the ability for the RPS to be
connected to an operational switch. Connecting an RPS to an operational switch can have an
adverse eect on the switch. It is best practice that both the switch and the RPS be powered
down prior to cabling them together. Once the cabling is completed, turn on the RPS, then
turn on the switch.
