Going Gigabit-need help!

Ok, so I'm trying to set up my gigabit lan, I've got 2 1000mb NIC's and 2 100mb nic's in each PC. MY new system (running XP) recognised the card, installed the card, and can use the new connection fine.
my old system (win98) recognised the card and installed it, but the card wont light up when cables are plugged in, I've tried using cables that are known to work, and linking them to my router that also is working, but stll no lights on that giga nic.

just so ya know I have 6 PC's already on the 100mb network with a router and switch daisy chained to my DSL modem. (this entire network works fine, and is accessable by both PC's)
I'm adding gigabit to my 2 main PC's, my new system has onboard gigabit so i just added a 100nic and it is setup and running the 100 network, it will work through either the orginal giga-nic or the newly installed 100nic. but the old PC is still on the 100 network through its original 100 nic, but the giga-nic seems unresponsive.

I was told I need to run straight cable from nic-to-nic on the gigalan, but that old box's giga-nic wont light up. I even tried to plug it into the 100 network, but no responce.

am I doing something wrong, or do i have a bad card? how can i tell?

Edit: once I figure this out I will want to set up the old box to share files across the gigbit, but not the 100. it needs to stay on the 100 line though in order to access the router->modem->dsl. I was thinking I could go to control panel/networking click on the TCP/IP for the 100nic and disable "file and print sharing" under the bindings tab. would that keep my internet connection on the 100 and let me transfer files to my new PC on th gigabit? I need to figure out how to get this card working first.
 
bump...

any ideas, why the giga-nic wont light up? I will put in the other pc to see if it will run, possibly newegg sent me a bad card.
 
I don't believe you use straight cables for gigabit NIC to NIC, you need a crossover cable. Also, you'll need a crossover cable that crosses all the pairs, since gigabit over copper uses all 8 wires.
 
I did a gigabit install at a customers office and had the same problems. Ended up having to rewire the whole building with Cat5E to get the NICS to work at gigabit speed.

To test you can force the NIC to 10 or 100 and see if you get a link light. This will tell you for sure if its a cable problem or not!
 
I tried pluging it into my router (100mb), but no light. why woldnt it light up for 1000?

also does anyone know if i need xover or straight for nic-to-nic conection in gigabit?

I've heard both ways and cant find sqaut about giganetworking.
 
NIC to NIC requires Crossover always!!

The problem I had was with a Gigabit NIC with standard Cat5 cable it wouldn't auto detect 10/100/1000 at all!! I had to force it to 100 to get the NIC to work. Once I replaced the Cat5 cable with Cat5E it auto detected 1000mb right away!
 
I'm using cat5e, but its straight, i'e got a few couplers with xover extentions in them, will throw one on and see how it does.

i had a thread last week (here) and had several people tell me that i needed straight cables for nic-to-nic since it's gigabit, sd something about it using all the pairs of wire.

Edit added link
 
To the best of my knowledge Cat5E still only uses 1,2,3,6 of the 4 cable pairs.

I could very easily be wrong though!! 🙂

 
when i get home i'm gonna try and use a xover cable, if that doesnt work i'm pulling the card and dropping it into my other box to se if it will light up.

Edit: Xover doesnt work, and the card wont light up on my 100mb line that works fine for the 100mb nic.

I checked the manual and it asays you can use either regular or xover cables. the card automatically detects.

You'd be wrong, gigabit over copper uses all 8 wires. 🙂 Some gigabit NICs will auto sense and run with a straight cable, some will require a cross-over.

<edit> I just received my pair of gigabit NICs, and they'll work with either straight cables or cross-over cables, they're auto-sensing. Clearly, I'll just whack together a straight CAT5e cable, since that's generally more useful around the house. 🙂
