I have some older Poweredge 1950s that run with a single power supply unit installed.
After many years of operation, the servers may not power up. I look at the LEDs on the power supply unit and they are off. There are two possible scenarios.
1. I take the problem power supply unit out of the server and plug it into a good working slot of a different server and if it doesn't work... it tells me the power supply unit has failed. I have to buy a new power supply unit.
2. I take the problem power supply unit out of the slot of the server and put it into the other (empty) slot and the server works again. I can continue to run the system.
My question is... in this second scenario, am I correct in assuming that there is a failure of the motherboard on the first power supply slot and in the future, if the second power supply slot fails in the same way... I will have to buy a new motherboard to get the server working again?
Thanks for any ideas!
