• Termination is provided on some devices with the use of small resistor packs
inside of the SCSI case that provide termination. If your SCSI device has an
internal terminator, you can use it in the last (or only) position in the chain. If
you wish to use the device in the middle of the chain, the internal termination
must be removed.
Removing Internal Termination
if Required
• If you are adding a device to the middle of your SCSI chain and that device
provides termination, you must disable the SCSI termination.
• If the device is the only one on your external SCSI bus or is being added to the
end of the SCSI bus, it must provide termination. Any other devices on the bus
must not provide termination.
• A long SCSI bus, or one with numerous devices connected to it, may require
termination at specific points in the middle of the chain. You should always
first try terminating only the device at the end of the chain. Typically in this sit-
uation, only one additional terminated device is required, so try adding
termination at different points in the chain.
Here’s how to install a SCSI device:
1. Turn off—your Genesis MP, the device you wish to connect and any other SCSI
devices already installed on the SCSI chain.
2. Connect the new device to the SCSI chain making sure that it has a unique SCSI ID
number, and that it follows the terminations rules listed above.
3. Plug the SCSI device’s power cord into a grounded electrical outlet.
4. Turn on all of your external SCSI devices.
5. Turn on your Genesis MP.
If you experience problems, review the SCSI ID and termination rules listed above. If
you continue to have problems, consult Chapter 5—Troubleshooting or contact your
