- In summary (to save even bigger fools as me from themselves, if any exist):
-
- The internal SCSI cable in 425e's is back-to-front. To make one of these,
- you start with a perfectly good SCSI cable, which has pin 1 on one plug
- connected to pin 1 on the other. Then you 'shave' off the little bump on one
- of the connectors and plug it in 'upside down'. Voila!
-
- Now if only I could understand why HP has done it... then I would quit my
- job and seek employment with them.
