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.
