Redundant 250 W DC supply

This HPE JL757A is a 250 watt redundant power supply that accepts a 36 to 72 V DC input and provides non-PoE output for compatible network switches. It measures 1.6 inches high, 2.9 inches wide and 8.9 inches deep, weighing approximately 3.30 lb. The unit is designed for hot-swap replacement in supported Aruba chassis.

Suited for Aruba 6300M deployments

This supply fits the Aruba 6300M switch and is intended for operators who need redundant DC power without Power over Ethernet capability. Buyers requiring PoE power delivery or an AC input voltage range should look at alternative models. Installations that do not use the 6300M platform cannot use this supply.

36-72 V DC input range

The defining specification is the 36 to 72 V DC input window; the supply will only operate within this voltage band. If the site DC bus falls outside these limits, the unit cannot be used. No other single parameter determines compatibility as decisively as the input voltage range.

أسئلة حول هذا المنتج

Should I pick this JL757A or a different wattage for my Aruba 6300M?

The JL757A delivers 250 W and is the model HPE lists for the Aruba 6300M; choose it when the switch chassis calls for a 250 W non-PoE DC unit.

What does 250 W actually provide inside an Aruba 6300M?

It powers the switch control plane, fans and all data ports without PoE, keeping the chassis running even if a second supply is added for redundancy.

What DC input range does the JL757A accept and what does that limit?

The unit operates from 36 to 72 VDC, so the upstream DC plant must stay within that window for the supply to start and remain stable.
