SCSI repeater card
Use this procedure to service the SCSI repeater card.
Before you remove and replace a SCSI repeater card, follow the instructions for your operating system to
save any jobs. For IBM i, power off the partition to save any jobs.
Important: The I/O adapter (IOA) needs to be powered off before disconnecting or reconnecting cables
or before removing or replacing the repeater card. The IOA can be powered off by powering off the IOA
slot or the logical partition. Depending on the disk protection level, the system or logical partition might
be affected during the service procedure. For additional information, see Installing PCI adapters.
Restriction: You must replace the repeater card with the same type of card to continue. If you are
changing card configurations from single repeater cards to dual repeater cards, stop here and follow the
instructions in Connecting the 5786, 5787, 7031-D24, or 7031-T24 to a system that has an AIX operating
system or Connecting and configuring the disk drive enclosure in a system that has a Linux operating
system.
The disk drive enclosure SCSI repeater card can be removed and replaced with the system and enclosure
power on. To avoid errors, you must power off the adapter that connects the disk drive enclosure to your
system.
To remove and replace a SCSI repeater card, complete the following steps.
