X over to Straight thru

[LadySlinger]

Is there a point in the network closet that you can use a device that connects a X over wiring to a straight thru? Reason why I'm asking is that I am currently on a network that has straight thru cables to the hubs, switches and routers in the back. The internet connection that I have been trying to switch us over to requires a X-over coming out of router (will not talk with a straight thru attached to it). I've tried a Ethernet switch and I've been working on my Firewall (which acts like a switch).

any help?

Thanks!

Unless I'm misunderstanding, just connect a crossover cable from the router to a regular port on the first switch device and you will be all set. Have a look at this page for cross over wiring configuration:

I use hot pink jumpers as my Crossover jumpers, so I can tell them at a glance from straight through jumpers. (somehow that reminds me they are not straight) Use any trick that works for you, but I encorage you not to just hope the next person will realize that this grey wire is 'special' and different from those grey wires over there.

In general you use a crossover cable when you go from active device to active device. A router is active and a switch is active. Same thing for switch to switch.

It's been my experience that crossover cables are red. That's really just the color of the cable. The real way to tell if a cable is crossover is to check the plugs to see if the green and orange pair are swapped.

Just a bit more info. Router to switch should be a straight through connection. They are dissimilar devices. Routers are designed with the expectation that they are to be connected to a switch or hub. Switch to switch is crossover.

What are you connecting your router to?

Also, if you don't wish to make or buy a crossover cable, there are adapters you can attach to a straight through cable to convert it. Just remember that every connection in the link is a potential failure, so a single crossover cable would ideally be the better choice.

Actually thanks for all your help, I found out that I needed a X-over from the router to the switch/Firewall device.

Then I had needed a crossover from the firewall/switch device to port 1 of the hub. I had kept trying to plug it into the uplink of the hub.

Thanks for the info though!

"Then I had needed a crossover from the firewall/switch device to port 1 of the hub. I had kept trying to plug it into the uplink of the hub."

If that's the case, then a normal, straight through cable would work to the uplink port. The uplink port will perform the 'cross over'.
