microprocessor and you have installed an additional microprocessor, your server
can now operate as an SMP server. Therefore, you might need to upgrade your
operating system to support SMP. See the ServerGuide
™
information in the
User’s
Guide
on the IBM
xSeries Documentation
CD and to 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 plan to attach external devices, you might need to order additional cables. To
select and order the correct cables for use with external devices, contact your IBM
marketing representative or authorized reseller.
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.
Note:
See “Ultra320 SCSI system-board connectors” on page 73 for additional
information about SCSI cabling and SCSI IDs.
If you plan to attach more than one external serial device, you must install the
optional second serial port that comes with your server.
Installing the external SCSI connector
Complete the following steps to install the optional external SCSI connector needed
to attach an external SCSI device:
1. Review the information in “Safety” on page v, “Installation Guidelines” on page 9,
and “Handling static-sensitive devices” on page 10.
2. Turn off the server and disconnect all power cords and external cables (“Turning
off the server” on page 12); then, remove the server cover (see “Removing the
server left-side cover and bezel (tower model)” on page 15 or “Removing the
server top cover and bezel (rack configuration)” on page 17).
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 68 for the 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 4 for the location of the SCSI connector); then, secure the
external SCSI connector at the other end of the cable into the external SCSI
knockout hole so the connector is accessible from the rear of the server.
6. Reinstall the server cover (see “Installing the server bezel and left-side cover
(tower model)” on page 62 or “Installing the server bezel and top cover (rack
configuration)” on page 65).
7. Reconnect all the devices, power cords, and cables that you disconnected;
then, turn on the server and all attached devices.
