Hard Drive Installation
■
Compaq does not recommend mixing different-width SCSI
devices on the same SCSI chain or on the same SCSI channel.
Mixing devices of different widths on the same chain or channel
will always result in the data transfer rate of the slowest device in
that chain. It is acceptable to mix Wide-Ultra2, Ultra 160, and
Ultra 320 devices on a single channel. Do not put Narrow devices
on a channel with any device type other than another Narrow
device.
For additional information about optional SCSI devices, refer to the
documentation included with the device or contact your Compaq
authorized dealer, reseller, or service provider.
CAUTION: Do not route cables near the air intake to the power supply.
Cables routed in this manner can block airflow to the power supply, causing
it to overheat.
Guidelines for Installing SCSI Devices
If you mix Ultra ATA and SCSI hard drives in the same system,
the Ultra ATA drive will be the boot drive unless the boot order is
changed in the F10 Setup.
When replacing a hard drive, the replacement drive should be of the
same type as the drive being removed. If you are replacing an
Ultra ATA hard drive with a SCSI hard drive, you will need a
multimode LVD SCSI cable option kit.
If only one SCSI hard drive is used, it should be installed in bay 4.
Before installing a SCSI device:
■
Verify the SCSI ID of the drive and, if necessary, set the SCSI ID
to a unique number. See “Guidelines for Using SCSI Devices” in
this appendix or refer to the documentation included with the
device.
■
Determine if the device requires that termination be enabled or
disabled. Set the termination if necessary. See “Using a SCSI
Cable” in this appendix or refer to the documentation included
with the device.
