5. If an IDE hard disk drive is in IDE connector 2, remove the drive and tray (save the screws that secured the tray to the system board); otherwise, remove the two existing screws near IDE connector 2 that secure the system board to the chassis, as shown in Figure 24 on page 45. 6. Install the I/O expansion card: a. Install the I/O expansion card tray. Secure the tray to the system board with the screws from the option kit, as shown in Figure 24 on page 45. b. Orient the I/O expansion card as shown in Figure 24 on page 45. c. Slide the notch in the narrow end of the card into the raised hook on the tray; then, gently pivot the wide end of the card into the I/O expansion card connectors, as shown in the illustration. Note: For device driver and configuration information to complete the installation of the I/O expansion card, see the documentation that comes with the option. Some documentation might also be on the IBM BladeCenter Documentation CD or the IBM BladeCenter T Documentation CD that comes with the BladeCenter unit. 7. If you have other options to install or remove, do so now; otherwise, go to "Completing the installation" on page 52. Installing an expansion unit You can install an optional BladeCenter SCSI Storage Expansion Unit or Peripheral Card Interface (PCI) I/O Expansion Unit on the blade server. Important: To avoid potential performance and reliability problems when configuring or replacing drives in a mirrored configuration, ensure that the storage capacities and speeds of the drives are identical. Notes: 1. After you install the SCSI storage expansion unit on the blade server, the blade server and expansion unit become a single unit that occupies two blade bays in the BladeCenter unit. 2. To ensure proper cooling and system reliability, make sure that each of the SCSI hard disk drive bays on the SCSI storage expansion unit contains either a hot-swap SCSI hard disk drive or a filler panel. For a list of SCSI hard disk drives supported by the blade server, go to the ServerProven list at http://www.ibm.com/pc/us/compat/. Figure 25 on page 47 shows how to install the SCSI storage expansion unit on the blade server. 46 BladeCenter HS20 Type 8832: Hardware Maintenance Manual and Troubleshooting Guide

Installing an expansion unit
You can install an optional BladeCenter SCSI Storage Expansion Unit or Peripheral
Card Interface (PCI) I/O Expansion Unit on the blade server.
Important:
To avoid potential performance and reliability problems when
configuring or replacing drives in a mirrored configuration, ensure that
the storage capacities and speeds of the drives are identical.
Notes:
1.
After you install the SCSI storage expansion unit on the blade server, the blade
server and expansion unit become a single unit that occupies two blade bays in
the BladeCenter unit.
2.
To ensure proper cooling and system reliability, make sure that each of the
SCSI hard disk drive bays on the SCSI storage expansion unit contains either a
hot-swap SCSI hard disk drive or a filler panel.
For a list of SCSI hard disk drives supported by the blade server, go to the
Figure 25 on page 47 shows how to install the SCSI storage expansion unit on the
blade server.
