System compatibilityAL1905A21-E6 is Extreme Networks 1000W PoE+ modular power supply. It fits VSP4450GSX and ERS5600 series chassis switches. It can be deployed in pairs for power redundancy. Supplies PoE power for wireless APs, IP phones and cameras. Widely used for enterprise wiring closet power spare replacement.

FunctionAL1905A21-E6 provides main system power and high-power 802.3at PoE+ power for the switch chassis. It monitors input voltage, output current, internal temperature and fan speed. It supports hot swap without chassis power off. It triggers alarms for over-current, over-voltage, over-temperature and fan failure. Used to replace faulty PoE power supplies for VSP/ERS series switches.

InstallationNo need to power off chassis for hot-swap replacement. Insert AL1905A21-E6 into the PSU slot of compatible switch. Secure the locking latch. Verify power status LED and PoE power budget on switch OS. Confirm normal output before putting into production.

InterfaceAC input socket, power status LEDs, built-in cooling fan, hot-swap ejector latch for Extreme Networks AL1905A21-E6.

FeatureOriginal Extreme Networks 1000W PoE+ AC power supply, hot-swappable, supports redundant power, over-current/over-voltage/over-temperature protection, built-in fan and self-diagnostic function. This spare supports enterprise PoE switch redundant power deployment.

DiagnosticPSU no power LED: check AC input cord and wall power. No PoE power output: verify PSU seating and switch PoE budget allocation. Over-temperature alarm: inspect fan rotation and chassis ventilation. Redundancy failover: confirm two PSUs are both healthy and properly seated.
