External Power Supplies

The following tables list the compatible power supply models for ExtremeSwitching switches that use

external power supplies for redundancy.

Caution

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.

For information about power supplies that work with other Extreme Networks switches, refer to

ExtremeSwitching and Summit Switches: Hardware Installation Guide for Switches Using ExtremeXOS 16

or Earlier.
