Cabling a ServeRAID adapter

Some xSeries 445 models come with an optional IBM ServeRAID adapter installed
to control the internal hot-swap hard disk drives. If you are installing an optional
IBM ServeRAID adapter, see the ServeRAID documentation and the cabling
information in this section to install the ServeRAID adapter.
Servers that do not come with an IBM ServeRAID adapter installed come with two
SCSI cables:
v One end of the first SCSI cable is attached to the connector on the SCSI
v The second SCSI cable is preinstalled along the inside of the server and both
The following procedure describes the internal cabling for installing a ServeRAID
adapter.
Important: When installing multiple ServeRAID adapters in a server that has the
PCI-X slot enabled for high scan (boot) priority, make sure that the ServeRAID
adapter controlling the startup (boot) drive is installed in a PCI slot that is scanned
before the PCI slots that contain the other ServeRAID adapters. See "PCI and
PCI-X adapters" on page 20.
Complete the following steps to cable the ServeRAID adapter:
b. Push the orange adapter retention latch toward the rear of the server and
open the tab.
c. Remove the expansion-slot cover and the PCI-X divider. If you are
hot-swapping a PCI or PCI-X adapter do not remove the PCI-X divider.
d. Carefully grasp the adapter by its top edge or upper corners and align it
with the connector on the PCI-X board.
e. If necessary remove the extension handles or bracket before installing a
long adapter.
Attention: When you install an PCI-X adapter, make sure that the
adapter is correctly seated in the connector slot. Improperly seated
adapters might cause damage to the board, the riser card, or the adapter.
f. Press the adapter firmly into the adapter connector.
g. If necessary reinstall the PCI-X dividers between the Active PCI-X adapter
slots.
h. Push down on the blue adapter guide to keep the adapter steady.
i. Close the tab. The orange adapter retention latch will click into place,
securing the adapter.
7. Connect the internal cables to the adapter. If you are installing a ServeRAID
adapter, see "Cabling a ServeRAID adapter" for instructions.
8. If you have other options to install or remove, do so now.

ends are loose inside the server. When you install a ServeRAID adapter, you will
connect this cable to the adapter and to the SCSI backplane on the I/O board.
