670W Redundant AC Power Supply

The IBM 32R2815 is a new 670W redundant AC power supply built for enterprise server deployments. It delivers hot-swap capability to keep critical workloads running during module replacement. System administrators managing IBM System x3550 platforms with Intel dual-core processors will find it a direct fit for maintaining uptime.

Capacity and headroom at 670W

Rated at 670W, the unit handles the full power envelope of the compatible x3550 configuration under typical dual-core processor loads. It accepts both 127V AC and 240V AC inputs, providing flexibility across rack power distributions. The redundant design means a single module failure does not interrupt operation, though total capacity drops to the remaining unit's 670W limit.

Integration into a server build

The supply slides into the x3550 chassis without additional adapters or cabling changes. Hot-plug support frees technicians from scheduling downtime for maintenance or upgrades. Builders using other server models or requiring higher wattage per module will need a different solution, as this unit is validated only for the specified IBM platform.
