Cisco AIR-SRVR-PWR= enterprise networking (router/Catalyst switch/UCS families) Power Supply

The Cisco AIR-SRVR-PWR= is a hot-pluggable, field-replaceable power supply module for Cisco’s rack-mount wireless LAN controller appliances, documented against both the 8500 Series Wireless LAN Controller (AIR-CT8510) and the Flex 7500 Series Cloud Controller. Both platforms are configured for dual, load-sharing power supplies as standard, so this module restores N+1 redundancy after a failed or removed unit rather than being required simply to power the controller. These controllers sit at the centre of large enterprise wireless deployments, managing hundreds to thousands of access points, so keeping both supplies live is a routine part of maintaining controller uptime. Confirm the exact controller platform and chassis generation before ordering, since input wattage differs between the hardware families sharing this part number. Tech-Star (UK-based, shipped worldwide) supplies Cisco wireless controller spares to keep large WLAN deployments fully redundant.
