Installing or removing internal drives
Ÿ
When you install devices in bays 2, 3, 5, and 6, you must disable
the termination for the devices before you install them.
Ÿ
If you connected external SCSI devices to your server, set the
termination for the last device on the external cable to Enabled.
See the device documentation for instructions.
If you plan to install both 16-bit (wide) and 8-bit (narrow) SCSI
devices:
1. Attach the 16-bit devices at the beginning of the SCSI chain.
2. Attach the 8-bit devices at the end of the SCSI chain.
Note: The beginning of the SCSI chain is the end closest to the SCSI
adapter or the system board.
This enables the UltraSCSI adapter to recognize all of the devices in
the SCSI chain, and thus ensures proper server operation.
Refer to the instructions that come with the SCSI device for more
information about termination.
Preinstallation steps (all bays)
Before you begin, be sure you have:
Ÿ
Read “Electrical safety” on page 70 and “Handling
static-sensitive devices” on page 71.
Ÿ
Read the documentation that comes with the option.
Ÿ
Read “Termination requirements” on page 111.
Ÿ
Verified that you have all cables, drive trays, and any other
equipment specified in the documentation that comes with
the internal drive.
Before you can install drives in your Netfinity 3000 server, you
might need to perform certain preinstallation activities. Some of the
steps are required only during the initial installation of an option.
1. Remove the server side cover (see “Disconnecting cables and
removing the side cover” on page 74).
