Redundant DC Power Module

The IBM 42C5279 is a plug-in redundant power supply built for systems that require -60 V DC input. It fits enterprise chassis that accept hot-swap power modules and need continuous uptime.

-60 V DC Input Requirement

This unit only operates from a -60 V DC source, so the installation site must already provide that voltage rail. Facilities running standard AC or positive-voltage DC cannot use this module without additional conversion equipment.

Hot-Swap Redundancy

The plug-in form factor allows replacement without powering down the host chassis, maintaining service continuity during a module swap. No extra cables or software licences are included in the package.

Questions about this item

What does the -60 V DC input mean for my rack installation?

The unit accepts a negative 60 volt DC source, so it connects directly to telco-style power plants without an AC-to-DC converter.

How does the plug-in module form factor affect the chassis slot?

It slides into a matching hot-swap bay and locks with a thumb screw, requiring no cables or tools for removal.

What does redundant power supply mean for uptime?

Two modules share the load; if one fails the other continues delivering power while you replace the faulty unit.
