    Figure 6 shows a configuration that is appropriate for a small installation where there is no main distribution frame (MDF). In this case, the RPI MDF capabilities provide the connections between the Meridian 1 system, Base Station power, and Base Stations. Essentially, the RPI unit functions as a distribution panel.
  • Page 28 Page 18 of 220 Installing the hardware Note: The polarity of the TCM connections is not important. If two power pairs are brought in, they must be connected with the same polarity to the termination board. WARNING! When using two power pairs, ensure they are connected with the same polarity.
