Example: Scalar AIT 440 library on two buses
In this example, a Scalar AIT 440 library with four tape drives is
connected to two SCSI buses:
S
On SCSI Bus A, a cable connects the host to the library, and jumpers
connect the library to Drive 1 and Drive 1 to Drive 2. Bus A is
terminated with an external terminator installed on the lower
connector for Drive 2.
S
On SCSI Bus B, a cable connects a second host to Drive 3, and a
jumper connects Drive 3 to Drive 4. Then, a cable connects Drive 4
to the other devices on Bus B.
