It should have enough power. I checked the power budget, it is as follows:
H2-CTRIO2 x 5 1375mA
D2-16ND3.2 x 1 100
D2-16TD2-2 x 1 200
H2-EBC100 x 1 300

TOTAL 1975mA
The rack supports 2600mA. So, this should be Ok.
We looked at the capacitors on the rack and nothing appears to be bulging. So, I think the capacitors are good.
We moved the 5th CTRIO2 to the 8th slot (rather than the 7th) and it does the same thing, so we believe the connector on the 7th slot is good.
We don't have an operator interface or DV-1000 connected. I am not using the 24v output either.
