Replaced Fuse. That brought back all the marginal power values from the regulators. One of the 744's is too high, needs to be brought under 5.1V per spec (it's 5.2ish). DC Low reading off the backplane of 3.6v and an AC low of 1.8v....is this bad? I think AC Low is too low, according to the manual it should be closer to the DC Low.
PROC and BUS lights on the front panel but no interaction with switches possible. Thanks Malcolm for helping me lift the power supply out of the rack, and for locating the bad fuse. Reply |
