10.2 INSTALLATION IN A UNIVERSAL STATION
A NIM module can be mounted in a Universal Station only if there is an empty console
furniture cabinet located adjacent to it. This is because of the bend-radius requirements of
UCN Trunk cables. To do this, two mounting brackets must first be mounted inside the
lower cavity of the station. Two sets of holes will have to be drilled in the cabinet.
10.3 INSTALLATION IN AN ERGONOMIC UNIVERSAL STATION
If a NIM is to be installed in a Universal Station, the taps are mounted to the mounting
brackets as shown in Figure 10-3 or 10-4.
Follow this procedure to install taps in a Universal Station in Ergonomic Furniture.
Step Action
1
Mount a tap to each mounting bracket.
• Isolated port marker must be located on right side of the mounting
bracket.
• Mount the tap with a bolt through the hole in the tap.
ATTENTION Do not mount with the grounding stud.
• Tighten the mounting bolt to only 25 inch pounds—just enough
to hold the tap fixed in place.
ATTENTION Do not crush the body of the tap.
2
Connect a 14 AWG/2.5 mm2 ground wire from each tap directly to the
nearest safety ground.
Do not daisy-chain the connection.
3 Connect a drop cable, 51195153-XXX (XXX is the length in meters),
to each drop cable connection 1.
It is very important to tighten the drop cable connectors to 25 inch
pounds to ensure an error-free UCN system.
4 Connect the other end of the drop cables to the NIM Modem card.
ATTENTION Pay strict attention to connecting the drop cable
from Cable A to the Cable A connection on the Modem card and the
drop cable from Cable B to the Cable B connection on the Modem
card.
5 Install the rest of the UCN Cable System as shown in the publication
UN20-100 that is found in the bag of taps. The same instructions are
found in Appendix A of
UCN Guidelines.
