5.1.4.7 RIM Connections to RF Source
To connect RIMs to RF source:
1. For each RIM - connect the RF coax cable to the RIM’s Simplex or Duplex QMA connectors. See HEU section 5.1.1.5
Figure 5-52. Example of RIM RF Source Simplex/Duplex Connections
2. Route the connected cables through the Cable Management Tray towards the right or left of the tray (depending on the
module location in the chassis).
3. Connect the RF coax cable from the RIM to the corresponding external RF source.
5.1.4.8 RIX 10 MHz Pilot Clock Connections
Note the following:
• This section is only relevant for configurations with additional IHU or HEU and OIU units.
• The REF IN and REF OUT pilot clock ports must be connected in a closed loop as shown in Figure 5-53.
• Both RIX modules of each chassis must be connected.
• The jumper cables are routed through the sides of the cable management tray and door.
To perform an RIX pilot clock connection
Referring to Figure 5-53 use the QMA/QMA jumper cable (PCKC47 provided with each RIX) to connect the REF OUT and REF
IN ports of each of the RIX modules in the HEU chassis.
