Connecting an External Tape Drive

The open peripheral bay at the front of your system can accommodate a user-accessible, half-height 5.25-inch device, such as a tape drive. This peripheral bay

is contained in a removable peripheral cage. The top of the peripheral cage accommodates a standard 3.5-inch diskette drive and CD-ROM drive. These two

drives connect to the system board via an interposer board mounted on top of the peripheral bay. See Figure9-1 for a general view of the various drives and

cables associated with the peripheral bay.

Before You Begin

This section describes how to install the following options:

l Devices that use the system's integrated small computer system interface (SCSI) host adapter

l Tape drives that use a controller card

To remove or install drives in the peripheral bay, you must open the system doors.

Interface Cables

If you install a SCSI device, you will connect it to the secondary SCSI interface connector (SCSIB [Channel B]) on the system board (see Figure9-1) or to a

SCSI host adapter on an expansion card.

These interface connectors are keyed for correct insertion. Keying ensures that the pin-1 wire on both ends of the cable goes to the pin-1 ends of the

connectors.

When you disconnect an interface cable, take care to grasp the cable connector, rather than the cable itself, to avoid stress on the cable.

SCSI Configuration Information

Although SCSI devices are installed essentially the same way as other devices, their configuration requirements are different. To configure a SCSI device

installed in the peripheral bay, follow the guidelines in the following subsections.

NOTE: You can also install a fifth hard-disk drive in the peripheral bay using an upgrade kit available from Dell.

NOTE: If you are installing a SCSI hard-disk drive, see "Installing Hard-Disk Drives."

WARNING: Before you perform the procedures in this section, you must turn off the system and disconnect it from its electrical outlet. For more

information, see "Safety First—For You and Your Computer" in "Checking Inside the System."
