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.

Step 1: Popping It Open

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

Step 2: Removing the Rear Facia

Step 3: Cable Layout

Step 4: No Idea What This Port Is For, But Thr RJ50 Socket at the Bottom in Black

Step 5: The Board Completely Removed

Step 6: Underside of Board Where the Socket Is Soldered In

Step 7: Adding the Printer USB Socket
