System compatibilityAL1905A3B-E6 is Extreme Networks high-power PoE modular power supply designed for ERS5900 PoE switches. It can be installed in pairs for power redundancy. It delivers high PoE power for high-power wireless APs, PTZ cameras and digital signage. Widely used for enterprise wiring closet power spare replacement.

FunctionAL1905A3B-E6 supplies chassis system power and high-power PoE power to ERS5900 switches. It monitors AC input voltage, DC output current, internal temperature and fan speed. It supports hot swap without shutting down the whole chassis. It triggers alarms for over-current, over-voltage, over-temperature and fan failure. Used to replace faulty high-power PoE power supplies for ERS5900 series switches.

InstallationHot-swap replacement without powering off chassis. Insert AL1905A3B-E6 into the PSU slot of ERS5900 switch. Lock the latch. Verify power LED status and PoE budget on switch operating system. Confirm stable power output before putting into production.

InterfaceAC input socket, power status LEDs, built-in cooling fan, hot-swap ejector latch for Extreme Networks AL1905A3B-E6.

FeatureOriginal Extreme Networks 1000~1400W PoE AC power supply, hot-swappable, back-to-front airflow design, redundant power capable, multi-protection including over-current/over-voltage/over-temperature, built-in fan and self-diagnostic function. This spare supports enterprise high-power PoE access layer deployment.

DiagnosticPSU no power LED: check AC power cord and wall power supply. Insufficient PoE power: verify PSU seating and switch PoE budget calculation. Over-temperature alarm: check fan rotation and chassis airflow. Redundancy switchover failure: confirm both PSUs are fully seated and healthy.

Product BriefAL1905A3B-E6 is Extreme Networks 1000~1400W hot-swappable AC PoE modular power supply with back-to-front airflow for ERS5900 PoE switches, supporting redundant power, classic spare part for enterprise high-power PoE wiring closet overhaul.
