HP X362 720W PoE Power Supply

This HP X362 unit is a proprietary 720 W power supply designed for HP 5500-HI 24 and 48 port PoE+ switches. It accepts a wide 100 to 240 V AC input and delivers a regulated -56 V DC output to power connected network devices. Network administrators use it as a direct replacement or redundant module for compatible switching infrastructure.

Integration and build fit

The supply fits the proprietary bay of the specified HP switches with dimensions of 1.6 inches high, 3.3 inches wide and 11.7 inches deep. It weighs approximately 3.97 lb and requires no additional cabling beyond the standard AC mains lead. Builders needing a different form factor, higher wattage or non-PoE voltage cannot use this module.

Bundled impact

No extra accessories, mounting brackets or management software are included with the unit. The package contains only the power supply itself, so installation relies entirely on the switch chassis rails and existing AC infrastructure. Administrators planning hot-swap maintenance should verify the switch supports redundant power bays before purchasing.
