hi,
After longtime usage of D2600 unit without problems, all of a sudden recently, after a power down and up, the unit is constantly on (the back on/off button does not switch down anymore, it's always on unless the power is switched off) and the fans are always running 100%, whereas before they would run 100% and noisy for 10 seconds or so, then reduce power). All leds are solid green except the 1st I/O on the back of the unit, the warning LED is solid amber.
The manual just says either locked or more serious problem. As these are no longer supported, I'll need to fix this up myself. So.... any ideas? Or just replace the whole I/O unit?
