Cabling example for a ServeRAID controller

You can install an optional IBM ServeRAID controller in your server to control the
internal hot-swap hard disk drives. A ServeRAID controller can, for example, enable
you to configure the internal hot-swap hard disk drives into disk arrays. The
illustrations in this section show the cabling for internal hot-swap hard disk drives.
You can also cable a ServeRAID adapter to external hard disk drives. See your
ServeRAID controller option documentation for complete instructions for installing a
ServeRAID controller in your server and for additional information about ServeRAID
controllers.
Notes:
1. This cabling example does not apply to the ServeRAID-5i controller, which uses
2. An optional ServeRAID-5i controller can be installed only in PCI-X slot 4. Slot 4
3. Connections made to external SCSI devices will be asynchronous.
If you are connecting the adapter to any internal SCSI backplane or device, you will
need to purchase additional SCSI cables. Contact your IBM marketing
representative or authorized reseller for additional information about the number
and types of cables that your server configuration requires.
Your server comes with one SCSI cable that can only be used with the integrated
SCSI controller with RAID capabilities that is on the system board. One end of this
SCSI cable is attached to the connector on the SCSI backplane, and the other end
is attached to the SCSI channel A connector on the system board. The SCSI
channel B connector on the system board is available for use, but the server does
not come with a cable attached to it.
The following procedure describes the cable routing that is necessary when you
install a ServeRAID controller other than ServeRAID-5i.

c. Press the adapter firmly into the expansion slot.
Note: If the server is subject to excessive movement or vibration, you can
secure the adapter with a screw: insert one of the backup
expansion-slot screws (stored next to slot 1) through the top of the
adapter bracket into the screw hole to secure the adapter before
proceeding to the next step.
d. Lower the adapter-retention latch over the top corner of the adapter. In slot
