Replacing the SAS drive controller card
The serial-attached SCSI (SAS) drive controller card attaches to the riser card assembly and coordinates communication
between the node hard drives. Replace a failed SAS card as soon as possible to reduce node downtime.
Prerequisite: Before replacing the SAS drive controller card, you must remove the PCIe riser card assembly. For more
information, see
Removing the riser card assembly on page 27.
1. Verify that the drive cables are labeled with their corresponding port ID numbers. If they are not, label them before
disconnecting them from the SAS drive controller card.
2. Disconnect the drive cables from the SAS drive controller card.
3. Remove the two mounting screws on the rear I/O panel.
