QUESTION:Storage shelf questions
The storgae shelf in question is labeled : DS-BA356-JD
I got it together with two separately shipped personality modules:
70-31490-01 (no other part no on the label) with two 68 pin SCSI connectors
70-33067-02 or DS-BA35X-FA with one very small SCSI connector
Questions:
1) does the shelf accept disks like the DS-RZ1DF-VW and/or the DS-RZ1CB-VW?
2) the 70-31490-01 has one bank of dip switches. I'm looking for
documentation
3) the DS-BA35X-FA has two sets of dip switches, need documentation for this
unit as well
4) the $64000 question is this combination going to work with a KZPSA
or KZPCM-Dx adapter?
ANSWER: The DS-BA35X-FA is a Single port, single-ended UltraSCSI personality module
for BA356. Although these settings cover the single or dual port
(DS-BA35X-FB) variants.
It has two sets of switches as you have observed (S3 and S4).
S3 (SCSI Address switch) - When shelf bus address switches on shelf one are
all set to OFF, then the SCSI
bus IDs are 0 through 6 on the first shelf.
When shelf bus address switches 1, 2, and 3 on shelf 2 are set to ON, and 4,
5, 6, and 7 are set to OFF, then SCSI bus IDs are 8 through 14.
S4 (Bus termination switch) - 1,2 are for Channel A. 3,4 are for Channel B
1 OFF or 3 OFF - 16 Bit External Bus Termination
Terminates all SCSI bus bits (full termination). This configuration is used
when the shelf is the end point in a SCSI bus and terminates all signals.
1 ON, 2 OFF or 3 ON, 4 OFF - 8 Bit External Bus Termination
Terminates only the upper 8 data. This configuration is used when the input
bus
is a wide (16-bit) bus and it continues as a narrow (8-bit) bus. This could
be
used with a tri-link to a narrow device.
1,2 ON or 3,4 ON - External Bus Expansion
No termination on the shelf. The shelf is not an end point of a SCSI bus
segment and no termination is needed.
