VHDCI or HD68 SCSI cable option
The VHDCI or HD68 SCSI Cable connects the server to external SCSI-based storage or backup devices.
The cabling option kit must be used for internal ports to be used externally.
IMPORTANT: To install the external SCSI option, an internal SCSI port must be dedicated for external use
only.
In addition to the VHDCI or HD68 SCSI cable, you will also need:
• T-15 Torx screwdriver
• Flathead screwdriver
NOTE: A PCI blank included with the optional Internal-to-External SCSI Kit enables the optional HD68 SCSI
cable to connect through a PCI-X or PCI Express expansion slot. Refer to the Internal-to-External SCSI Kit
installation instructions for details.
To prepare the server before installing or removing options:
1. Power down the server (on page 16).
2. Unlock and open the front bezel ("Front bezel" on page 19) (tower servers only).
3. Extend or remove the server from the rack ("Extending the server from the rack" on page 16).
4. Remove the access panel ("Access panel" on page 20).
WARNING: To reduce the risk of electric shock or damage to the equipment, disconnect
power from the server by unplugging all power cords from the electrical outlets.
CAUTION: Failure to correctly power down the server could result in damage to equipment or loss of
information.
5. Using a T-15 Torx screwdriver, remove a SCSI knockout located on the rear of the chassis and retain
the screw.
6. Remove any brackets on the VHDCI cable, if necessary.
7. Connect the preassembled cable bracket assembly through the external SCSI knockout on the rear of
the chassis, and secure the cable using the screw retained in step 5.
8. Connect the other end of the VHDCI SCSI cable to an available SCSI port or a PCI card.
NOTE: Refer to the documentation that shipped with the external storage device for more information.
