Here are some tips to keep in mind when attaching SCSI devices to the OCTANE
workstation.
• You can mix Ultra and Fast devices on the same bus. You can also mix 16-bit and
8-bit devices on the same bus. The overall performance of a mixed bus can vary
widely.
• To daisy-chain a mix of wide and narrow devices, place the wide devices (as a
group) closest to the OCTANE workstation where the bus is wide, and place the
narrow devices (as a group) at the end of the daisy chain.
Note: Be sure touse anadapter orother special cable that terminates the upperhalf
of the SCSI bus when converting from the final wide device to the first narrow
device. Silicon Graphics supplied cables have this integrated into the cable, but not
all third-party cables have the terminator integrated into the cable.
• Unsupported devices maynot work withthe OCTANE workstation, andmay cause
problems with supported devices.
• The length of combined SCSI cables determines how many devices can be daisy-
chained.
• Set addresses manually only on external SCSI devices. See the device manual for
setting the address on the device. Each device needs to have a unique address.
• Drives can beeasily damaged.Handle your drivecarefully;do notdropit or handle
it roughly.
Cleaning DAT or DLT Drives
If you use your DAT or DLT drive frequently, magnetic dust or debris can collect on the
heads of the drive. This can make your DAT or DLT tapes unreadable or unwriteable.
If the green LED on the front of the DAT drive flashes at about 5-second intervals, clean
