Redundant Server Power Module

This hot-swap module delivers 585 watts to compatible IBM xSeries servers. It replaces a failed unit or adds N+1 redundancy without shutting the system down. Part numbers 24R2640 and 24R2639 are interchangeable. Buyers needing non-redundant desktop ATX power cannot use this module.

Thermals Noise and Power Draw

The unit shares the server chassis airflow, so acoustics and temperatures follow the host system fan profile. Under typical load it draws up to 585 watts from the mains and converts it with the efficiency rating certified for the original platform. No standalone fan curve or noise figure is published for the module alone.

Build Integration Requirements

Installation requires an empty redundant power bay in a supported IBM xSeries chassis and the matching power backplane. The module frees the primary supply from single-point-of-failure risk and leaves all drive bays and expansion slots untouched. Builders without a compatible redundant bay must choose a different form factor.

Questions about this item

How do I install the 24R2640 redundant module in my xSeries server, and which step is often missed?

Slide the 24R2640 unit into the hot-swap bay until the latch clicks, then verify the green AC and DC LEDs are both lit; the step most often missed is confirming both LEDs before assuming the module is active.

What maintenance or replacement will the 585W AcBel module need over its service life?

Plan to clean the intake vents every six months and replace the internal fan assembly if bearing noise appears; the electrolytic capacitors typically reach end-of-life after five to seven years of continuous operation.

What limit appears first when the 24R2639 supply runs at full 585W load for extended periods?

The thermal protection circuit triggers first; sustained maximum output raises internal temperatures until the over-temperature shutdown engages, reducing available power until the unit cools.
