HPE 5400R 1100W PoE+ ZL2 server power supply

HPE 5400R 1100W PoE+ ZL2 Power Module

This HPE 5400R module delivers 1100 W of AC power for HPE switch chassis that accept ZL2 form-factor supplies. It supports PoE+ budgets so access ports can power phones, cameras and wireless access points without separate injectors. The unit operates from 120 V or 230 V mains and weighs 8.6 units. It is built for network engineers who need redundant, hot-pluggable power in a campus or data-centre rack.

Hot-plug installation in compatible HPE chassis

The supply slides into the designated power-supply bay and locks with the integrated latch; no tools or cable harnesses are required. Firmware on the switch detects the new module automatically and brings it online within seconds. A common error is inserting the unit into a bay reserved for non-PoE supplies, which prevents the PoE budget from activating. Verifying the bay label and chassis compatibility list before insertion avoids that mismatch.

Sustained load behaviour in redundant configuration

Under continuous PoE+ draw the module shares current evenly with any second supply, keeping each unit below its thermal limit. The fan curve ramps gradually as inlet temperature rises, maintaining stable output voltage without abrupt speed changes. If one module fails or is removed, the remaining unit carries the full load without voltage droop, allowing the chassis to stay operational until a replacement is fitted.
