operating system to support SMP. See the ServerGuide information (“Using the
ServerGuide Setup and Installation CD” on page 18) and your operating-system
documentation for additional information.
If your server has a RAID configuration using the integrated SCSI controller with
RAID capabilities or has a ServeRAID controller installed and you have installed or
removed a hard disk drive, see the ServeRAID documentation on the
IBM
ServeRAID Support CD for information about configuring your disk arrays.
Connecting external options
If you install an optional SCSI adapter or use channel B on the integrated SCSI
controller for external devices, you can attach external SCSI devices, such as a
SCSI storage expansion enclosure, to your server. For a list of supported options
for your server, go to http://www.ibm.com/pc/us/compat/ on the World Wide Web.
If you plan to attach external SCSI devices, you must order additional SCSI cables.
To select and order the correct cables for use with external devices, contact your
IBM reseller or IBM marketing representative.
Note: See “Ultra320 SCSI system-board connectors” on page 106 for additional
information about SCSI cabling and SCSI IDs.
Complete the following steps to attach an external SCSI device:
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).
Attention: To ensure proper system cooling, do not remove the server cover
for more than 30 minutes during this procedure.
3. Remove the external SCSI knockout on the rear of the server (see “Cabling the
server” on page 102 for external SCSI knockout location).
4. Follow the instructions that come with the option to prepare it for installation and
to connect it to the server.
5. Route one end of the optional external SCSI cable to the external SCSI B
connector (J51) on the system board (see “System-board internal cable
connectors” on page 45 for the location of the SCSI connector). Attach the other
end of the cable to the external SCSI knockout device connector.
6. Reinstall the server cover (see “Installing the server bezel and left-side cover
(tower model)” on page 96 or “Installing the server bezel and top cover (rack
configuration)” on page 99).
7. Reconnect all the devices, power cords, and cables that you disconnected;
then, turn on the server and all attached devices.
You can attach additional external options to the input/output (I/O) connectors on
the front and rear of your server. (See “Input/output connectors” on page 104 for
more information.)
Complete the following steps to attach an external device:
1. Review the information in “Installation guidelines” on page 41, “Handling
static-sensitive devices” on page 42, and “Safety information” on page 163.
