Hello

Are you getting LEDs on the system board or power supplies. If you are not getting LEDs on the power supplies then I would check your power source and power cables. If all of the power supplies fail to power on then it is likely there was an environmental issue that affected all of them while they were not being used.

Thanks

You should get lights on the power supplies if they are connected to a power source. I just pulled a power supply out of one of my 2950s and connected a power cord. I had a green LED on the PSU without it even connected to the server. If you are not getting LEDs on any of your power supplies then I would suspect that the power supplies, power cables, or power source is failed.

Since all of the components appear to have failed I would suspect an environmental issue occurred while they were being stored. If all of the PSUs are failed then there are likely other components that are failed.

Thanks

Sorry to bump:

A 2950 will do this if one of the PSUs is bad and the CMOS battery is dead. You will not even see a greed LED on the good PSU until it has powered up at least once in the chassis.

Remove the CMOS battery and see what happens.

My test case was a 2950 that had been running a long time and refused to power back on. After removing the CMOS battery the server will power up regardless of whether the good/bad PSUs are inserted in slot 1/2 or 2/1.

It is also possible removal of the CMOS battery effected a BIOS reset...... certainly I have seen weird stuff like this happen on other hardware when there were BIOS setting integrity issues.
