No display on the NLH3000 server

[william_161]

I'm not getting any display on this server, It was working fine and was switched off over night but the next day when i switch it on nothing seem to appear on the monitor, I've changed the system board, i/o card, processor and memory but its still the same even though the system board/ i/o card havent been tested yet. Does any1 know how whats wrong with it ? I know it happen once before and all we did was to reseat the memory and it worked fine till now

I assume you have tried a different monitor? And does it appear as if the server is powering up normally? All the fans running on this Netserver LH3000?

Yes i have tried another monitor, The system power up but no display at all

1. Does it appear as if the server is powering up normally? Can you hear the fans running? What is the status of the front panel LEDs when powered up?
2. Remove all DIMMs. If you do not hear a series of 4 beeps the system board is kaput.

I've changed the systemboard on the server with another one but the problem still there. On the control pannel i get a NOS Memoery dump, warning: halt server. on the service menu. Changed memory and systemboard problem still there

Have resolved this problem?

I have a Similar problem, but if I pull the power cord, the server will boot up.
