IBM Voltage Module E880 Power 8 01AF563 00RR716 VRM-MIO-CJ

IBM POWER8 High-Density Voltage Regulator Module (VRM)

1. General Product Overview

The IBM 01AF543 / 01AF563 is an enterprise-class, heavy-duty Voltage Regulator Module (VRM) engineered exclusively for mission-critical IBM Power Systems built on the high-performance POWER8 processor architecture. This module drops directly into the specialized power plane sockets of IBM’s flagship enterprise-level computing nodes and expansion drawers. Its primary function is to deliver tightly regulated, low-ripple, high-amperage power to the multi-core processors and custom memory sub-systems, sustaining platform resilience across extreme virtualization and database workloads.

2. Technical Specifications

3. Hardware Compatibility & System Infrastructure

This high-capacity VRM is engineered specifically to align with high-end, heavy-density enterprise environments. It natively supports:

• IBM Power System E880 / E880C (Machine Type-Models: 9119-MHE)

• IBM Power System E870 / E870C (Machine Type-Models: 9119-MME)

• IBM PCIe Gen3 I/O Expansion Drawer (Model: EMX0 / Feature Code: EMX0)

Deployment Architecture Note: In the scale-up E870/E880 processor nodes and EMX0 expansion drawers, these VRMs are deployed in redundant ($N+1$) matrix banks. They are equipped with distinct blue mechanical retention clips that latch into the heavy backplane guides, ensuring clean contact pressure under continuous thermal cycles.
