External Power Supplies
The following tables list the compatible power supply models for ExtremeSwitching switches that use
external power supplies for redundancy.
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.
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.
