Fuel - on board network connector failed

Unread postby Mark_G » Fri Aug 18, 2017 6:45 am

Recently my house was directly stuck with a lightning strike.
(I got a lot of damage, like a partly blown roof, broken windows, etc..)

Happily, the power-lines for my computers are very well secured, and no psu blowed away.
However, My cable network lines where electrically overloaded, and a lot of network cards, routers etc.. are now broken.

This happens also to my Fuel.
I can boot my fuel, but the lights on the network connector don't flash up.
Also On start-up I get a warning that no network connection could be established.

I checked the network cables on other systems, and there is no fault in the wiring.

So my questions :
- Are there some specific irix commands, I can check the status of the network card?
- Is there a fuse on the mobo, I can check ?
- Do I need to replace the full mobo ?

Thanks in advance,
Mark

There are PCi compatible NICs, so the board replacement shouldn't be needed.

As for checking the status, I wonder does the card appear in the hinv?

Possible, it became disabled also, and can be enabled using the on board serial connector, which I cannot for the life remember the name now. L1? heck.. Something like that.

Hello,

The Network connector is shown in hinv. It gives :
Integral Fast Ethernet: ef0, version 1,

Possible, it became disabled also, and can be enabled using the on board serial connector, which I cannot for the life remember the name now. L1? heck.. Something like that.


I'll check this out. However I'm not an SGI guru.

Thanks

If the onboard network is toast, you could use this as an excuse to put a Gigabit Ethernet card in the Fuel. I upgraded my own Fuel this way last year and don't use the onboard Ethernet any more.

:Fuel: - Lithium: R14000 600MHz CPU, 4GB RAM, V10 Graphics, 72GB 15k HDD & 300GB 10k HDD, 1Gb/s NIC, New/quiet fans, IRIX 6.5.30

I was aslo thinking that way.
However, I like a full working motherboard too. So, I'm looking to some blown fuse.
Because the machine shows ef0 ( 'hinv -vm' and 'configmon - h').

Definitely time to drop in a PCI-X gig card....but you want the onboard to work so you can install from the network.

It's possible the network chip was damaged, but I wonder if the transformer is what took the blow and could be replaced....that's where I'd look first.

Thanks for the suggestion.
I will check the transformer.

Here are some pictures of the Ethernet jack and nearby area:

(note the bodge wires leading from the ethernet jack to the interfacing chip.

There are 2 components that could have failed in your case - the magnetics (transformer) in the jack itself:

(not an exact match, didn't have time to look for it)

Or the transceiver chip:

Both can be replaced rather easily, hope that helps.

Hello,

Thanks for all the information.
In a couple of weeks, my Fuel undergoes the surgery.
I hope that everything goes well. I'll keep you informed.
