Question about Dell PowerEdge 1600SC Server

No Video Signal on 1600sc

My Dell 1600sc suddenly stopped sending a video signal. Upon reboot, everything appears to power up, yet I am still not receiving a video signal to troubleshoot problems. I added a PCI video card with no change. The 1600sc is network attached, yet I can not map a drive to the 1600sc from another computer, so I suspect it is not booting all the way up. I am not getting any system beep codes either. I verified that the monitor, keyboard and mouse were all okay using another computer. Upon inspection inside, all cables and connections are tight. The only thing that looks out of place is a blinking green led in the lower right side of the motherboard when powered up, and it stays blinking until it is powered down. The tiny number next to this led is U23.

Many thanks for any help.

Re: No Video Signal on 1600sc

I also have this problem with my Dell Poweredge 1650, integrated Ati Rage XL doesn't work. But when I add PCI graphic card, I get the video from it. Could integrated video be somehow disabled?

Re: No Video Signal on 1600sc

I have at this same problem. Its not the Bios, CPU, RAM or power supply. Its the mother board itself. I ordered a new mother board off of and my server works fine!

Re: No Video Signal on 1600sc

It seems that you cannot upgrade the video card on certain Poweredge Servers. Not sure how that is possible, but Dell probably did it becuase now these servers could be used for power user workstations - and repurposing doesn't give dell any more money.

No Idea what the problem could be.

Re: No Video Signal on 1600sc

The beeping sound might be the the caused of wrong memory module, fan not plug in right, power supply wires not connected properly. i work in a company where i have to maintained 67 Dell 1600sc servers.

Re: No Video Signal on 1600sc

Disconnect from the network and all other accessories, and power up the system, this might be due to a faulty device attached to the system, eg: when you connect a usb faulty device the boot takes very long time, sometime it does not boot up.

A power outage cause dell server 1600sc to shut down & no display on the monitor

Hello here is the homepage.

There should at least be a message on the monitor indicating there is no signal coming to the monitor. The first thought that comes to mind if all is connected would be that the power supply has failed.
And maybe the graphic card.

Call also the DELL support in your country they will be glad to help
and they probably know the fault.

Dell PowerEdge 1600sc server won't boot.

> black screen & flashing cursor ...

Damaged boot-record on the disk-drive???

Was it configured to try to boot from 'A:' ?
Disconnect the hard-drive & CD/DVD drives.
Put a diskette into the drive, and see if it tries to find a boot-record on the diskette.
If it tries, then it has P.O.S.T.'d correctly.

> no beep codes

When it worked, did it beep _once_ when P.O.S.T. completed?

Taking out the RAM _should_ cause some beep codes, i.e., "no RAM".

> anyone?

Replace the monitor?

Replace a dead video-card?
Or, add-in a video-card, and connect a monitor to it, leaving the original monitor connected to the original video-card. One of the two displays should show the P.O.S.T.

Ibm xseries 235 eserver....all of a sudden stopped was set up through a kvm swtich, the kvm detects a signal and lights up the apprpriate port, yet nothing is displayed on the monitor....

Please expalin how you know "drives are good" (sic) As it would appear to me that this is indeed your problem? Unless as you say the video card has turned up it's toes. As you said the best way to check that is to enable the onboard Video and check, exactly what happens when you do that? Yes it will automatically use the video, it would install a generic video driver,and show video, are you sure the monitor is OK,have you swapped it out? Simply removing the Video card will automatically enable the onboard video, so you won't need to get inro BIOS. Check the RAM too, and remove any other cards in it.

DELL PowerEdge 1600sc - New motherboard no joy

Are you sure the new motherboard was of the same revision as the old one? Dell shipped 400FSB boards during the beginning of the 1600SC line and shipped 533Mhz boards during the end of the run. I would check the revision level of the motherboard to make sure it is compatible. If it's the same revision, I would start small and connect just one CPU and put the system at 512mb ram and see if that works. If this works, you can begin to add additional components as needed.

Good luck

Dell PowerEdge 1600SC Server occasionally beeps when running

Check out this site:

Write down the exact number of beeps and how long they last to find what the error means. The are call BIOS post codes and they resemble Morse Code. (ie. one long, 3 short, 2 long = RAM issue) Good luck!!

Can not access bois

It hangs there probably becuase one or more of the drives are dead or are almost there. Check and see the lights on the drives are falshing funny or too long or are yellow. If you find one of them that are that way, pull it out and then reboot.

See if that helps.
