dec tk50z-ga issues

[Plamen Mihaylov]

Hi all,

Since I don't have a machine with qbus and I need to backup some vms and
ultrix tk50 tapes, I purchased a tk50z-ga from ebay.
Upon power up, the red led flashing rapidly(which means drive fault)  then
goes to solid red.
I've never used TK50 drives in the past so if you have any hint how to
troubleshoot this it would be appreciated. Or should I start looking for a
replacement?

Regards,
Plamen
