IBM MAX5 for System x memory expansion module
If you purchased an optional IBM MAX5 for System x (MAX5) memory expansion
module, it supports up to 32 DDR3 DIMMs, two 675-watt power supplies, and five
40 mm hot-swap speed-controlled fans. It provides added memory and multi-node
scaling support for host servers. The MAX5 expansion module is based on eX5, the
next generation of Enterprise X-Architecture. The MAX5 expansion module is
designed for performance, expandability, and scalability; the fans and power
supplies use hot-swap technology for easy replacement without requiring that the
expansion module be turned off.
If you are adding an optional MAX5 or scaling to another server, see the rack
installation instructions that comes with the cable option kit.
The following illustration shows the MAX5 memory expansion module. The
illustrations in this document might differ slightly from your hardware.
