RPS-90 Redundant Power Supply
Notice
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
Notice
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 RPS-150XT provides backup power to Extreme Networks stackable switches. If for some reason the
switch loses power from its internal power supply, the RPS-150XT can provide up to 150 W maximum
operating power to support switch operation.
The power supply ships with the following:
•
RPS cable
•
Four rubber feet (for flat surface installation)
The RPS-150XT is compatible with the following Extreme Networks switches:
