we have experienced some problems with the second dell machine,
The power light is flashing amber
If the power light is blinking amber —
The computer is receiving electrical power, but an internal power problem might exist.
Ensure that the voltage selection switch is set to match the AC power at your location (if applicable).
Ensure that the processor power cable is securely connected to the system board.
I can find no fault of anything that could explain this.
Power supply is dead, we unplugged the power supply and hooked up the other one from the other dell machine that was brought at the same time. It brought the system to life. So I am now on the lookout for another power supply, must be 24 pin + 4 pin, and have SATA connections on it.
We may have managed to find a supply for this machine, both through the technician at work and the other through a reader of the blog. Will update when we get these and connect them up.
Meanwhile the first dell machine is going hard at it, although we found another issue when reinstalling ubuntu 7.10. It would stop at 80% install. Thanks to one of the students looking up the Internet it was a simple fix, unplug the Ethernet cable and away it went. The first install we did we didn't have the network cable attached, I wonder why?
yay, we managed to get a power supply that fits into the machine and connected. we now have ubuntu 7.10 installed and running on it. Now I need to get more network cables connected and work out how we can get a couple more wireless access points. I think I might need to raid the old ones from maths department
