Some options have device drivers that you need to install. See the documentation
that comes with your option for information about installing any required device
drivers.
Your server comes with one or two microprocessors installed on the system board.
If your server comes with two microprocessors or if your server comes with one
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 User's Guide on the IBM xSeries
Documentation CD and your operating-system documentation for additional
information.
If you have a RAID configuration on your server using the integrated SCSI
controller or if your server has a RAID controller installed, and you have installed or
removed a hard disk drive, you might need to reconfigure your disk arrays. See the
RAID documentation on the IBM xSeries Documentation CD for information about
reconfiguring your disk arrays.
Connecting external options
If you install a SCSI adapter or use the external SCSI connector, you can attach
external SCSI devices, such as a SCSI storage expansion enclosure, to your
server. You can attach additional external options to the other input/output (I/O)
connectors on the front and rear of your server. (See Chapter 3, "Input/output ports"
Complete the following steps to attach an external device:
1. Review the information in "Safety" on page v, and "Installation guidelines" on
2. Turn off the server and all attached devices (see "Turning off the server" on
3. Follow the instructions that come with the option to prepare it for installation and
