Installing Shunt/Terminal Strip
To install the shunt or terminal strip, attach two dual-pin units vertically to P1 and P2 four-pin
jumpers corresponding to the RJ-45 port using a balun, as shown in
Figure A-20 . Any other RJ-45
ports on the NIM card connected to 120-ohm lines do not require shunts.
