Power Injectors with Soekris boards?

[Bruno Lopes F. Cabral]

Hello there

I'm buying my first soekris net4511 boards.
I'm aware it is capable of accepting -48VDC
power injectors, and I'm planning to buy
this one, from cisco

can any of you point me the correct RJ45
cable pinup to make it work? i.e. which
par will contain the VDC and which one
will be GND?

are any of you already doing this?

any help will be greatelly appreciated

Cheers
