835W Redundant Power Supply for x3650

This IBM 24R2731 unit delivers 835 W of redundant AC power to compatible x3650 servers. It accepts 127 V AC or 240 V AC input and uses a proprietary plug-in module form factor. The supply weighs approximately 4.40 lb and is sold new. It is designed for administrators who need a direct replacement module for supported IBM racks.

Installation and common issues

The plug-in module slides into the server bay and locks with a built-in latch, requiring no cables or tools. Installers sometimes forget to seat the latch fully, which leaves the unit on standby power only. Another frequent error is mixing this proprietary supply with non-IBM units, which prevents redundancy from functioning. Always verify the server model before fitting.

Compatibility limited to x3650 series

This power supply is validated only for IBM Server x3650 Series systems. It will not operate in other IBM chassis, third-party racks, or desktop workstations. Buyers who need a supply for a different server line must source the correct proprietary module for that platform.
