5. Use the up or down arrow button to scroll through the possible SCSI ID
settings. Press the Enter button when the desired SCSI ID is displayed.
6. Repeat steps 4 and 5 to set other SCSI bus IDs as necessary.
7. Press the Escape button repeatedly until the default menu is displayed.
8.12.2.1.2 Cabling the TL881 or TL891 DLT MiniLibrary
There are six 68-pin, high-density SCSI connectors on the back of the TL881
or TL891 DLT MiniLibrary standalone model or rackmount base unit. The
two leftmost connectors are for the library robotics controller. The middle
two are for tape drive 1. The two on the right are for tape drive 2 (if the
second tape drive is installed).
______________________ Note _______________________
The tape drive SCSI connectors are labeled DLT1 (tape drive 1)
and DLT2 (tape drive 2). The control panel designation for the
drives is DLT0 (tape drive 1) and DLT1 (tape drive 2).
The default for the TL881 or TL891 DLT MiniLibrary is to place the
robotics controller and tape drive 1 on the same SCSI bus (Figure 8–18). A
30-centimeter (11.8-inch) SCSI jumper cable is provided with the unit. Plug
this cable into the second connector (from the left) and the third connector. If
the MiniLibrary has two drives, place the second drive on the same SCSI
bus with another 30-centimeter (11.8-inch) SCSI bus jumper cable, or place
it on its own SCSI bus.
______________________ Notes ______________________
The internal cabling of the TL881 and TL891 is too long to allow
external termination with a trilink/terminator combination.
Therefore, the TL881 or TL891 must be the last device on the
shared SCSI bus. They may not be removed from the shared
SCSI bus without stopping all ASE services that generate activity
on the bus.
To achieve system performance capabilities, we recommend
placing no more than two tape drives on a SCSI bus.
We recommend that tape devices be placed on separate shared
SCSI buses, and that there be no storage devices on the SCSI bus.
The cabling depends on whether or not there are one or two drives, and for
the two-drive configuration, if each drive is on a separate SCSI bus.
