card bracket ServeRAID M5120 adapter
You can purchase an optional ServeRAID M5120 SAS/SATA Controller. This adapter can be installed only in
the PCIe slots listed in “Supported adapters” on page 70. 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.
Notes:
• For additional information and notes about installing adapters “Installing an adapter” on page 69.
• 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).
• 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 flash power module” on
page 89 for more information).
• This adapter is for external RAID and can be used when external storage expansion units are attached to
the server.
To install the ServeRAID M5120 SAS/SATA adapter, complete the following steps:
Note: If possible, backup or record your RAID configuration information before replacing the adapter. See
the documentation for your RAID adapter for information and instructions. Documentation for ServeRAID
adapters can be downloaded from the Lenovo Support Portal.
Step 1. Read the safety information and installation guidelines, see “Safety” on page v and “Installation
guidelines” on page 38.
Step 2. Turn off the server (see “Turning off the server” on page 23) and all attached peripheral devices.
Disconnect all power cords; then, disconnect all external cables from the server.
Step 3. Remove the top cover (see “Removing the server top cover” on page 40).
Step 4. Remove the fan cage assembly (see “Removing the fan cage assembly” on page 44).
Step 5. Remove the microprocessor and memory expansion tray (see “Removing the microprocessor and
memory expansion tray assembly” on page 292) or DIMM air baffle (see “Removing the DIMM air
baffle” on page 220), whichever one is installed.
Step 6. Touch the static-protective package that contains the adapter to any unpainted surface on the
outside of the server; then, grasp the adapter by the top edge or upper corners of the adapter and
remove it from the package.
