APC UPS RS 1000 USB Conversion

Hi all,
I have just been given an Uninteruptable Power Supply. Great! One drawback, no cables!

It needed:
1 x USB to RJ50 cable
RJ50 cables look like normal ethernet RJ45 cables but have 10 pins not 8.

At least 1 kettle lead with a male connection one end and a female connection the other.

I looked at making a cable, but i would need an RJ50 plug. That wouldn't do! I will replace the socket instead.

Popping It Open

I popped it open to see if adding/replacing the data port was a viable option.
