Hi KIrk,
The H771 is a rock solid power supply. I never saw one go bad while in
field service, but they are getting old. Checking the output voltage and
ripple is not a bad idea.
forgive me for asking, but where are you located? The RX02 had 4 different
power hanesses for i20, 220, 50 hz and 60 hz. Also different belts amd
pulleys. if any of this is wrong you cn see weird problems. A lot of RX02s
and replacement drives were soul through brokers who never asked or were
never told where the unit was going. if you aren'y useing 120/60 that
would be my first thought.
Is the problem the same when booting off either drive? Also check the
switches and the resistors on the head cables.
Good luck, Paul

people that may have
debugged them in the past and see if they agree with what I?m finding:
I?m trying to get a RX02 + RX211 + 11/44 going. The RX02 appears to power
up OK (fan and motor spinning). I verified I have the DY boot rom in the
44. Attempt booting from the console:
>>b dy
S
17777707 173436
Which halts in the DY boot rom. I look at the base RX211 register:
>>e 17777170
17777170 104040
From the manual this like the controller is present but the high order bit
is set indicating an error
Looking at the status register;
>>e 17777172
17777172 000010
Bit 3 == RX AC LO - This bit is set by the interface to indicate a power
failure in the RX02 sub- system.
So start looking at the RX02 power supply?
