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.)
