Installing an optional IBM ServeRAID SAS/SATA ControllerYou can purchase an optional IBM ServeRAID SAS/SATA controller. You mustinstall the optional ServeRAID adapter in PCI slot 3 on PCI riser-card assembly 2.If the server does not already come with PCI riser-card assembly 2, you mustpurchase the PCI riser-card assembly option. For configuration information, see theServeRAID documentation at http://www.ibm.com/systems/support/.Attention: Some cluster solutions require specific code levels or coordinated codeupdates. If the device is part of a cluster solution, verify that the latest level ofcode is supported for the cluster solution before you update the code.Note:1. Follow the general rule for connecting the SAS signal cables to the adapter anddrive backplane, port 0 on the adapter to port 0 on the drive backplane; thenport 1 on the adapter to port 1 on the drive backplane (depending on the drivebackplane you install in the server).2. When you install an IBM ServeRAID SAS/SATA adapter that has a battery, youmust install the ServeRAID battery remotely on the remote battery holder inthe server (see “Installing a RAID adapter battery remotely in the server” onpage 60).To install an IBM ServeRAID adapter, complete the following steps:1. Read the safety information that begins on page Safety and “Installationguidelines” on page 30.2. Turn off the server (see “Turning off the server” on page 21) and all attachedperipheral devices. Disconnect all power cords; then, disconnect all externalcables from the server.3. Remove the top cover (see “Removing the server top cover” on page 33).4. Carefully grasp PCI riser-card assembly 2 by the blue touch points and pull ituntil the PCI riser-card assembly disengages from the connector on the systemboard.5. Pull the release pin on the rear of the PCI riser-card assembly to unlock theretention latch; then rotate the retention latch to the open position.6. Touch the static-protective package that contains the ServeRAID adapter toany unpainted surface on the outside of the server; then, grasp the adapter bythe top edge or upper corners of the adapter and remove it from the package.7. Align the ServeRAID adapter so that the keys align correctly with theconnector on the PCI riser-card assembly.Chapter 2. Installing optional devices 49
