  • TypePower Module
  • 920 W output powers demanding server workloads

920 W Redundant Power Module

The Lenovo 69Y3749 is a 920 W hot-swap power module designed for compatible IBM and Lenovo servers. It provides redundant AC-to-DC conversion to keep critical workloads running during a single-module failure. The unit installs directly into the server chassis without cables. System administrators managing high-uptime environments will recognise the part number 69Y3749 for procurement.

Fits Redundant Server Bays Only

This module suits IT teams maintaining supported Lenovo or IBM rack servers that accept 69Y3749 units in a redundant configuration. It is not for desktop PCs, workstations or non-redundant server chassis. Buyers who need a standalone PSU for a custom build or a different form factor should look elsewhere. Compatibility must be verified against the server model before purchase.

920 Watt Output Rating

The module delivers 920 W of output power to the server backplane. This rating determines whether the unit can support the installed CPUs, memory, drives and add-in cards under full load. Check the server's power budget and the number of populated bays to confirm capacity. If the configuration demands more wattage than 920 W, additional modules or a higher-rated alternative are required.

Questions about this item

Which Lenovo server chassis accepts the 69Y3749 920 W power module?

The 69Y3749 is designed for Lenovo System x and ThinkServer racks that support hot-swap redundant power modules; verify the exact server model in the hardware maintenance manual before purchase.

How do I install the 69Y3749 module and what step is often missed?

Slide the unit into the open bay until the latch clicks, then secure the retention lever; the missed step is failing to lock the lever, which leaves the module unseated and prevents power-on.

When should the 69Y3749 power module be replaced?

Replace the module if the front amber fault LED stays lit, the server logs a power-supply critical event, or the unit fails the built-in self-test during POST.
