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 expansion module be turned off.

Notes:

1.Before you attach the memory expansion module to the server and try to use it, you must update the server firmware with the latest level of firmware or code. The firmware in the server and the memory expansion module must be at the same level. If you attach and try to use the memory expansion module without updating the server firmware or making sure that the firmware in the server and memory expansion module are at the same level, you might get unexpected system behavior, or the server might not power on. For special instructions to follow before you attach the memory expansion module to the server, see http://www.ibm.com/support/entry/portal/ docdisplay?lndocid=MIGR-5085756.

2.When you add an optional memory expansion module to your server configuration and you plan to use the optional USB flash device with VMware ESXi embedded hypervisor software, see the documentation that comes with the USB flash device and the operating-system installation instructions for installing VMware ESXi (or ESX, depending on your environment) on your server at http://www.ibm.com/systems/support/. The documentation provides additional installation and configuration information that you must to follow before you use the memory expansion module.

If you are adding an optional memory expansion module or scaling to another server, see the rack installation instructions that come with the cable option kit.
