Boot problem with a ProLiant DL 380 server,

Clear NVRAM

Install latest version of JAVA . it would be Java Script problem

Check the back for a bad power supply. You should be using dual power with dual supply. It should have indicator light on somewhere. Connect to another source if no LED is on.

Just Clear NVRAM (by SW6 maintainance switch )/ else systemboard has to be replaced

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.

Unfortunately, this is most likely a bad system board. Have you tried to RDP or telnet to the machine after it boots? That is, assuming you have some form of remote access enable of course.

Use a different monitor and connect it directly to the server, if problem persist you have a problem with the systemboard or microprocessor.

First of all, Dl380 is an hP product.
Secondly your ghost version seems a bit old as ghost 14 is the latest version. Having said that the problem could be at two ends.
1. At the ghost side where your version doesnot contain NIC drivers for PXE boot and HDD drivers for imaging. To fix this you can try manually adding the drivers to the network boot or floppy boot diskette.
You can get the drivers from HP website or the PSP CD that came with the server.

Alternatively you can upgrade to RDP instead of GHOST, RDP is Symantec's offering sold by HP for imaging it's servers.

2. There's some problem with your NIC settings or card if you are trying to PXE boot.
If you are using a floppy drive/ usb HDD, check from BIOS if it is detected.

The G5 Series is fairly new, if you're within warranty, call 1800-okCompaq.

Could be a bad cable, a bad monitor, or bad computer hardware. Any display at all or any beep codes?

On the back, the ml350 G5 will likely have an additional Network interface jack-- this may be labeled ILO. The ILO network connect allows you to use another PC on the same network to access this system (like a remote control via VNC or RDP) even if it won't power up--literally. Inside the ILO page, (you'll need the IP address of the ILO, the default account is administrator, and the default password is listed ona paper tag attached in the rear or on a sticker. If you can get into ILO via web browser: https://ipddress of ilo, you can check the Integrated log, which can shed some light on any failures.

do you use software/hardware raid?
hopefully hardware :-)
and is it mirrord or raid5?
