cabling.
Table 5-9: RGPS Cable Install Procedure
Step Action
1 Route the twisted pair cable through the previously installed conduit to the RF Cabinet I/O area, and
to the punch block through the rubber boot in the floor of the I/O area (See Figure 5-6). Refer to
Figure 5-1 for the recommended locations.
NOTE
The rubber boot is sized to seal a cable with an outer diameter of either 1/4 or 1/2, if a different
sized cable is used heat/cold shrink or other means may be required to ensure a good seal. A tie wrap
or hose clamp must be used to ensure a good seal around the cables at the boot.
2 Connect the RGPS pairs from the cable to the punch block (using only the recommended 110 style
punch tool CGDS237744 or equivalent) per the pin callouts in Table 5-10.
3 Strain relief the cable by tie wrapping it to the punch block mounting bracket as shown in Figure 5-5
The RGPS cable is comprised of 6 twisted pairs of wires.
For proper RGPS operation, each BLACK wire in this
cable is unique and must be paired with its proper mate.
