Installing a SCSI Device in a SCSI Device Shelf

Almost any Fast SCSI-2 single-ended 3.5-inch or 5.25-inch device, such as a digital audio tape (DAT), CD-ROM or SCSI hard disk drive, can be installed in a SCSI device shelf. The details for configuring the device, such as jumper settings, are supplied by the manufacturer of the device. Internal cabling configurations are described in the “Cabling Configurations” section of this manual. This section describes the basic process of installing a SCSI device in a SCSI device shelf. A SCSI hard disk drive is used as an example.

Use only the cables supplied by HP. The storage system includes an actively terminated SCSI cable for your SCSI tray devices. Fast SCSI-2 (up to 10 MB/second synchronous transfer) devices require an actively terminated SCSI cable.

NOTE To use SCSI mass storage devices, you need to obtain trays to install them in the storage system. Contact your HP dealer for obtaining these trays: 5.25-inch tray (HP D2199A), 3.5-inch tray (D2198A).

For installation of a third-party, non-HP device in a SCSI device shelf, consult the HP BBS (408-553-3500) for recommended supplies and instructions.

The following example demonstrates the procedure for installing a SCSI hard disk drive:

1.Verify that the device is not terminated because the internal SCSI cable includes a built-in terminator. If you are installing a SCSI device that uses a built-in terminator, remove the terminator from the device before proceeding with the installation. The HP accessory devices available for your storage system are shipped with the terminators disabled.

2.Power down the unit. (Since all the data stored on all the drives in the storage system is inaccessible while the system is powered down, consider informing all users before powering down the storage system.)

3.Open the door of the storage system as described in the section “Opening the Door.”

4.Position the first device closest to the SCSI cable terminator located at the end of the SCSI cable.

5.Remove the screws that secure the filler panel to the disk shelf. (Do not attempt to pry the plastic cover off the storage system.)
