Non-standard LAN cabling 
 
In some cases cable could be a non standard cable or the far end (patch panel) connected in 
a non-standard way (not in accordance to TIA-568-A or B). In such case you will have to do 
slightly more work mapping the existing non-standard connections.  
 
Please refer to the table bellow. This table should be filled at the far end by looking at the 
actual connections. Fill out the second column and then use the third column to connect the 
wires to the Flex-Jack terminal block according to the numbering shown in the third colum. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Table 6.1 - Non-standard wiring table 
 
See picture bellow of the Flex-Jack terminal block connections and numbering. Note that 
contact numbre 8 is at the left (closest to the A/B marking on the label). 
 
        Figure 6.1 - Flex-Jack terminal block numbering 
 
For example
, if you  have a non-standard wire, and you  wrote in the first line of the table 
above (RJ-45 Pin number 1) = green, then you need to connect the green wire (on the Jack 
PC side) to connector number in the Flex-Jack terminal block.
