Cisco AIR-PWR-5500-AC Power Supply

The Cisco AIR-PWR-5500-AC is an AC power supply module designed for Cisco 5500 Series Wireless LAN Controllers, delivering reliable, hot-swappable power to support centralized WLAN management and maintain controller operation. It accepts 100–240 VAC input at 50/60 Hz and is intended for installation inside the controller chassis in enterprise racks, data centers, and large campus networks where centralized wireless control is essential. The module supports redundant configurations, uses integrated cooling with system airflow, and fits as an internal chassis module to sustain secure connectivity and stable performance for wireless access points across large deployments. Common replacements in Cisco deployments include the Cisco PWR-C2-250WAC, and this power supply is compatible with Cisco 5500 Series devices as a dedicated power option.
