HP CD-Writer Plus Internal 9200i Drive - Manual (Page 30)

30 Installation Troubleshooting
■ The new drive is the last of several devices in a chain connected to
one SCSI card. In this case remove the termination in the device that
was previously at the end of the chain. See the documentation
provided with the device to learn how to disable the termination.
REMOVE the ACTIVE TERM jumper if:
■ The new drive is connected between two existing SCSI devices, or
between a SCSI device and the SCSI card. Since the drive is not the
last device in the chain it must not be terminated.
More information on device termination is available on page 8.
Make sure the SCSI card is terminated correctly.
Like other devices in a SCSI chain the card itself must have the
appropriate termination. Most SCSI card are terminated when
shipped.
■ If you previously had only external SCSI devices and the new drive is
the first internal device in the chain, you may have to remove or
disable the termination on the SCSI card. While most newer SCSI
cards adjust automatically, consult the documentation that came
with your card to find out if you must disable the termination
manually.
Check the SCSI cabling.
The total length of cabling in a SCSI chain should not exceed 6 meters
(about 20 feet). However, problems may appear before reaching these
limits.
■ If you are using more than 4 meters (13 feet) of cable, remove some of
the devices in the SCSI chain to see if the new drive starts working
correctly. If it does, try using shorter cables if possible. If shorter
cables do not solve the problem you may need to get an additional
SCSI card to handle some of the devices.
Make sure your computer meets the minimum system
requirements.
