SCSI Control Connection
Connecting to a Client or a Server Other Than Sun
To connect to the server or client SCSI control cable:
1. Bring the SCSI 68-pin cable from the server or client to the connectors on the right
front bulkhead. Connect the SCSI server or client cable to one of the two
connectors.
2. If the path continues from this point, connect a second cable to the second
connector on the bulkhead. Route this cable through the hole in the tape library
floor.
3. Continue routing the cable under the frame (toward the rear of the tape library) and
up through the hole provided for the drive cables. Insert the cable into the first drive
channel connector (at the bulkhead).
4. If the path terminates, connect a terminator at the other connector on the bulkhead.
Connecting to a Sun Microsystems Server
Connections to the Sun server are as follows:
Differential Operation
•
The distance from the tape library to the Sun server can be up to 18 meters
(60 feet.).
•
The differential mode of operation allows the user to connect the drive SCSI
paths to the same cable if desired.
The connection at the Sun server is 68-pin.
After the type of operation is determined, connect the Sun server using the
procedure described in the paragraph above.
WARNING. The pass through terminator is installed inside a NonStop server.
Note. When configuring the tape library to a UNIX workstation, a dedicated SCSI host bus
adapter is recommended:
•
For wide SCSI adapters, any target from 0 through 4 can be assigned for the tape library.
•
For narrow SCSI adapters, the range of targets is 0 through 6.
To use the embedded system bus on the SPARC station, select target 6, 5, 2, or 0 for the tape
library. The remaining targets are reserved for Sun peripherals.
For the IBM RISC System/6000, available targets on the embedded system bus are 6, 5, 3,
and 2.
