ServeRAID M5120 adapter
You can purchase an optional IBM ServeRAID M5120 SAS/SATA Controller for
System x. This adapter can be installed only in the PCIe slots listed in “Supported
adapters” on page 68. For configuration information, see the ServeRAID
documentation at http://www.ibm.com/supportportal/.
Attention: Some cluster solutions require specific code levels or coordinated code
updates. If the device is part of a cluster solution, verify that the latest level of
code is supported for the cluster solution before you update the code.
Note:
v For additional information and notes about installing adapters “Installing an
adapter” on page 66.
v Follow the general rule for connecting the SAS signal cables to the adapter and
drive backplane: port 0 on the adapter to port 0 on the drive backplane and port
1 on the adapter to port 1 on the drive backplane (depending on the type of
drive backplane you install in the server).
v This adapter comes with a RAID cache card. The cache card comes with a
battery or flash power module that must be installed remotely in the server (see
“Installing a RAID adapter battery or flash power module” on page 87 for more
information).
v This adapter is for external RAID and can be used when external storage
expansion units are attached to the server.
To install the IBM ServeRAID M5120 SAS/SATA adapter, complete the following
steps:
1. Read the safety information that begins on page “Safety” on page vii and
“Installation guidelines” on page 33.
2. Turn off the server (see “Turning off the server” on page 21) and all attached
peripheral devices. Disconnect all power cords; then, disconnect all external
cables from the server.
3. Remove the top cover (see “Removing the server top cover” on page 36).
4. Remove the fan cage assembly (see “Removing the fan cage assembly” on page
40).
5. Remove the microprocessor and memory expansion tray (see “Removing the
microprocessor and memory expansion tray assembly” on page 278) or DIMM
air baffle (see “Removing the DIMM air baffle” on page 210), whichever one is
installed.
