6. For additional information about cabling, see “Cabling example for a ServeRAID
controller” on page 63 and “Cabling the server” on page 102.
7. The SCSI cables that come with your server can only be used with the
integrated SCSI controller with RAID capabilities. If a RAID controller other than
the ServeRAID-5i is installed, you must use SCSI cables that are compatible
with that controller. To select and order the correct cables for use with your
RAID controller, contact your IBM reseller or IBM marketing representative.
Installing the 3-Pack Ultra320 Hot-Swap Expansion option
Notes:
1. The 3-Pack Ultra320 Hot-Swap Expansion Kit might contain some components
that you will not need for this procedure. For information about the contents of
this option kit, see the documentation that comes with the option kit.
2. The 3-Pack Ultra320 Hot-Swap Expansion option does not support use of a
SCSI repeater card.
Complete the following steps to install the 3-Pack Ultra320 Hot-Swap Expansion
option:
1. Review the information in “Installation guidelines” on page 41, “Handling
static-sensitive devices” on page 42, and “Safety information” on page 163.
2. Turn off the server and disconnect all power cords and external cables
(“Turning off the server” on page 9); then, remove the server cover (see
“Removing the server left-side cover and bezel (tower model)” on page 51 or
“Removing the server top cover and bezel (rack configuration)” on page 53).
3. If necessary, remove the air-baffle assembly, adapter-support bracket,
adapters, and plastic dividers. See “Removing and installing the
adapter-support bracket” on page 54 and “Working with adapters” on page 56
for additional information.
Attention: The server electromagnetic interference (EMI) integrity and
cooling are both protected by having the front bays covered or occupied. When
you install the 3-Pack Ultra320 Hot-Swap Expansion option, save the filler
panels from the bay, in case you later remove the 3-Pack Ultra320 Hot-Swap
Expansion option and do not replace it with another device.
4. Remove the two filler panels from the removable-media bay opening. Store the
filler panels for future use.
5. Remove the custom metal slide rails and screws that are inside the 5.25-inch
removable-media drive bays. Store the slide rails and screws for future use.
6. Align the 3-Pack Ultra320 Hot-Swap Expansion option with the empty
removable-media bay opening, adjacent to the standard hot-swap hard disk
drive backplane.
7. Partially slide the 3-Pack Ultra320 Hot-Swap Expansion option into the guides
through the front of the removable-media bay opening, as shown in the
following illustration. Leave adequate room at the rear of the 3-Pack Ultra320
Hot-Swap Expansion option to connect the required cables.
