Don't know whether this particular answer in the thread applies to your case but I thought it was useful to mention it :
hi tj,
The status bits read failed errors reported for tray 1 are due to I2C access errors, I2C access requires at least on power modules per tray to have power connected, this is a known limitation.
if the modules are unpowered we can explain this, if they are connected and receiving AC input, it could mean that the tray's i2c bus is broken, never seen that before to be honest... dont expect teh power modules themselves busted, all 3 of them seems irregular.
you could swap a module between trays to see if the problem moves or not to confine it to module or tray.
cheers
