1000BaseT crossover

Does anyone know what the pinout is for 1000BaseT cables?

Hello,

check this link:

Gigabit Ethernet RJ-45 Port Pinouts

http://www.cisco.com/univercd/cc/td/doc/product/core/7301/7301icg/5418a.htm#wp1049402

It looks like the pinouts are:

1 - 3

2 - 6

3 - 1

4 - 7

5 - 8

6 - 2

7 - 4

8 - 5

Can you post a short note if this is correct ?

Regards,

That is correct:

For a standard Category-rated cable cross the following pair, maintaining polarity:

Green <--> Orange

Blue <--> Brown

(which is the pinout you described above).

I found a mini-dongle at Fry's that is a GigE crossover adapter (all four pair) ~US$4.00. Easier to drag around than another cable.

Good Luck
