2.You will need a DWZZA-VA signal converter for the BA350. Ensure that the DWZZA-VA single-ended termination jumper, J2, is installed. Remove the termination from the differential end by removing the five 14-pin differential terminator resistor SIPs.
3.Attach an H885-AA trilink connector to the DWZZA-VA 68-pin high-density connector.
4.Install the DWZZA-VA in slot 0 of the BA350.
9.4.1.2Preparing a BA356 Storage Shelf for Shared SCSI Usage
To prepare a BA356 storage shelf for shared SCSI bus usage, follow these steps:
1.You need either a DWZZB-AA or DWZZB-VW signal converter. The DWZZB-VW is more commonly used. Verify signal converter termination as follows:
•Ensure that the DWZZB W1 and W2 jumpers are installed to enable the single-ended termination at one end of the bus. The other end of the BA356 single-ended SCSI bus is terminated on the personality module.
•Remove the termination from the differential side of the DWZZB by removing the five 14-pin differential terminator resistor SIPs. The differential SCSI bus will be terminated external to the DWZZB.
2.Attach an H885-AA trilink connector to the DWZZB 68-pin high-density connector.
3.Set the switches on the BA356 personality module as follows:
•If the BA356 is to house disks with SCSI IDs in the range of 0 through 6, set the BA356 personality module address switches 1 through 7 to off.
•If the BA356 is to house disks with SCSI IDs in the range of 8 through 14, set BA356 personality module address switches 1 through 3 to on and switches 4 through 7 to off.
If you are using a DWZZB-AA do not replace the personality module until you attach the cable in the next step.
4.If you are using a DWZZB-AA signal converter, use a BN21K-01 (1-meter) or BN21L-01 (1-meter) cable to connect the single-ended side of the DWZZB-AA to the BA356 input connector, JA1, on the personality module. Connector JA1 is on the left side of the personality module as you face the front of the BA356, and is hidden from normal view. This connection forms a single-ended bus segment that is terminated by the DWZZB single-ended termination and the BA356 termination on the personality module. The use of a 1-meter cable keeps the single-ended
