Note Rather than using the LAN wires, you can use the LAN connection port on the TCC2/TCC2P/TCC3 if
preferred. Use either the backplane connection or the TCC2/TCC2P/TCC3 front connection. You cannot
use the LAN backplane pins and the LAN connection port on the TCC2/TCC2P/TCC3 simultaneously;
however, it is possible for you to make a direct connection from a computer to the LAN connection port
on the TCC2/TCC2P/TCC3 while the LAN backplane pins are in use as long as the computer that is
connected directly to the TCC2/TCC2P/TCC3 is not connected to the same LAN.
Step 1 Using #22 or #24 AWG (0.51 mm² or 0.64 mm²) wire or CAT-5 Ethernet cable, wrap the wires on the
appropriate wire-wrap pins according to local site practice.
Cross talk might result if both receive (Rx) and transmit (Tx) pins connect on the same twisted pair of
Caution
wires from the CAT-5 cable. The two Tx pins need to be on one twisted pair, and the two Rx pins need
to be on another twisted pair.
A frame ground pin is located beneath each pin field (FG2 for the LAN pin field). Wrap the ground shield
of the LAN interface cable to the frame ground pin.
