4)Respect the maximum allowable cable length for your SCSI chain.

In order to ensure optimum performance, you must respect the maximum allowable length for your SCSI chain. The maximum allowable length of the chain depends on the type of devices (SE, LVD or mixed) connected to it. Consult the table above, or contact your computer supply specialist for more details.

5)Never mix HVD devices with SE or LVD devices.

HVD devices require a special controller and are not compatible with LVD or SE devices. If you connect an HVD device to an SE or LVD device, none of the devices will work properly. Furthermore, you may damage the devices or your computer system.

6)Turn on all of your SCSI peripherals before turning on your computer.

Before turning on your computer, always power on all of the devices in your SCSI chain. Otherwise, the computer will not recognize the devices. Also, never leave any unpowered devices in your SCSI chain. If there is an unpowered device in your chain, the other peripherals may not work correctly and directory and/or data corruption may occur.

Warning! Always power down the computer before powering off your SCSI devices. Failure to so can result in the corruption of the hard drive’s directory.

7)Turn off your computer and SCSI peripherals before disconnecting them from the chain.

Do not disconnect any SCSI peripherals from your computer or chain before turning off the computer and all of the SCSI devices. Doing so may damage the peripherals and/or the computer system.
