User this information for instructions on how to replace the ServeRAID M5120 SAS/SATA Controller.

Note
  • For additional information and notes about installing adapters Installing an adapter.
  • 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 flash power module that must be installed in the slots on the bottom of the storage book (see Installing a RAID adapter flash power module in the storage book for more information).
  • This adapter is for external RAID and can be used when external storage expansion units are attached to the server.

You can purchase the optional ServeRAID M5120 SAS/SATA Controller for System x. The ServeRAID M5120 adapter provides base RAID levels 0, 1, and 10 support. See Supported RAID adapters for more information. For configuration information, see the ServeRAID documentation at the Lenovo Support Portal.

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.

To install a 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.
  1. Touch the static-protective package that contains the new ServeRAID M5120 SAS/SATA 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.
  2. Reinstall the RAID cache card, if one was removed earlier (see Replacing a RAID cache card).
  3. Align the ServeRAID M5120 adapter so that the keys align correctly with the connector on the I/O book board.
  4. Insert the adapter into the connector, aligning the edge connector on the adapter with the connector on the I/O book board. Press the edge of the connector on the adapter firmly into the connector. Make sure that the adapter snaps into the connector on the I/O book board securely.

    Attention: Make sure that the adapter is correctly seated into the connector before you turn on the server. An incorrectly seated adapter might cause damage to the I/O book board or the adapter.

  5. Close the PCIe retention lever.
  6. Reconnect the cables to the adapter and to the RAID cache card.
  7. Follow the instructions for replacing the PCIe I/O book for which you replaced the adapter.
  8. Reconnect the power cord and any cables that you removed.
  9. Turn on the peripheral devices and the server.
  10. Import your RAID configuration to the replacement ServeRAID adapter as a foreign configuration. See the ServeRAID-M Software User Guide for instructions.
