We put a Dell PowerEdge 1950 into storage for 13 months and when I tried to use it, it would not power on. The 'AC available' LEDs on both PSUs are lit, a LED on the motherboard is lit and there are 2 LEDs on the DRAC card - one is lit and the other is blinking. Comparing these LEDs with a working 1950, these would appear to be normal.
If I take the cover off, the intrusion switch triggers the usual I1910 warning message on the LCD display and removing items such as the riser cards also provokes the correct error messages. The CMOS battery was dud and I have replaced this and I have also reseated all connectors, CPUs and memory DIMMs and reset the NVRAM using the jumper on the motherboard. The DRAC works as normal but if I attempt to power the system on using SMCLP via a ssh connection with the 'start /system1' command, it says the system has successfully been powered on when in fact it hasn't
If it press and hold the front ID button for a few seconds, it comes up with the error code 'FB'. What does this mean? An identical server of the same age and also stored for 13 months powered up with no problems so I've really no idea what could be wrong - these servers are the ones with two 3.5" SAS disks and SAS RAID controller.
