VG224 cable going to ground??

Answered Question
Jan 28th, 2009


I'm having an amphenol 50 pin RJ-21 cable made by a cable manufacture. I sent them the pinout requirments from this URL

The cable manufacutre came back with a question regarding the pinout requirments. They want to know why they are asking for pin's 25, 50, 51, 52 to go to GND. Specifically 51 and 52 because they don't exist in a 25 pair cable.


I have this problem too.

Hey Ryan,

Long time my friend :) These Pins/Pairs will not go to Ground. They are completely unused. I'm guessing this diagram was copied from some other reference.

Just a plain old RJ21 (Male) like this;

Cisco RJ21 Cables

Hope this helps!
