Unable to boot HP DL380 G4 with display message no signal on the monitor

Hello, I think you might find more information on starting up the DL380 G2 at the link shown below:
http://h20566.www2.hpe.com/hpsc/doc/public/display?docId=emr_na-c00972124

Also, the replacement instructions, in case it needs to be replaced, (and relevant troubleshooting info) for the 5i controller are found in the link here :http://h20566.www2.hpe.com/hpsc/doc/public/display?sp4ts.oid=316587&docLocale=en_US&docId=emr_na-c00688182

Please first make sure that you are using the proper startup boot disk for the server before entering the CD ROM option from the boot menu. Also, check the front panel of the SCSI drives for any errors or blinking LEDS that correspond to an error code. You can run a diagnostics CD/DVD that arrived with the manufacturer's pack to detect any raid issues on startup.

If you are still facing difficulties with booting up the server, you can find a video for replacement of the appropriate scsi drive here if you are still facing any issues of your scsi drive. Try a different hard disk or check the relevant diagnostics to verify whether is the controller or the drive that complicates the booting of the server

For more details check the scsi manual in the link below (section "FBWC LEDs" , pages 15-17).

I bought an HP DL380 G4 from here, and called them up any time I had a question like this. These guys were amazingly smart. Perhaps you can call them up and pretend to be a customer?

Clean the Server with blower.
Update BIOS

that's it

Clear NVRAM.

Connect the keyboard, mouse, monitor, network cable and power cord. press the power button on the front panel of the server. If the OS is installed the server will boot.

We had the same problem with a G5 version of the dl380, no video at boot or OS boot. This model fortunately had another video out on the front panel that worked. However, I believe that the G4 does not have that option coupled with using the Rage XL's from ATI for video. Have you tried installing another video card into the expansion slots for video? If you are able to, you may find that when you run your smartstart and load/reload the OS your video will work with the onboard.

Make sure the BIOS is fully updated from the HP website. Most DL3-series servers supported booting from an external USB cd, try F10 or F12 at boot in order to bring up a boot menu.

I'm afraid that the server video cards on these are pretty poor, the only way to improve this is to add a PCI video card (I added a cheap MX440 to a server I run to get around this). If your PCI slots are all filled up then I'm afraid there's really nothing you can do.

You could TRY to decrease the color bit depth, and see if that helps. Often the video drivers don't support detecting when a higher resolution is possible due to a lower bit depth, or the cards don't actually use less storage for them. (the problem is a lack of RAM on the card to hold a full screen full of pixels at a higher resolution.)

Hi,
Is your server under carePAQ/ support by HP.
Please go to the System Settings/BIOS of the server by pressing F9 while booting. Check for error messages.

Please check for the processor support matrix also. You may want to try upgrading the motherborad firmware berfore loading this proc.

Cheers,

To enter the BIOS of a ProLiant DL380 you have to press "F9"
