[Info-vax] DS15 SCSI cable question

[David, Island Computers]

To answer your questions

The SCSI cable from the DS10 is fine. If you are using the DS10 scsi
cable on with a front acces cage then make sure the terminator is last
as the fas cage is self terminating
Secondly, the external scsi (second port and second ctr PKB) is a
VHDCI connector. THe internal controller U160 is a standard 68 pin
connector
If you need more space in your system behind the fornt access storage
cage, our new IC-ZDS15-RP is the same height and width but 1.5"
shorter than the HP version so gives you
loads more room for cables etc.
