4.4 Connect the Cables
Note: This section references RAU5x, however connections are performed the same for both RAU5 and RAU5x models.
Note: The cable connections slightly defer for systems with or without add-ons. Refer to the sections relevant to your system
deployment.
4.4.1 Locate Required Connection Cables
Locate the following connection cables leading from the cable infrastructure:
• DC wiring:
• For RAU5x or RAU5x+RxU/RxU2325 configurations - one pair for “Main Power” connection
NOTE: For RAU5x+GEM or RAU5x+ RxU2325+RxU67 configurations- two pairs; one pair for “Main Power” connection.
Another pair for “Secondary Power” connection depends on cable AWG and distance from power source, and is according to
calculation before the deployment. The RAU will raise an alarm when not enough power to turn on the RxU67.
• Fiber pairs (Corning SMF-28
®
fiber or compatible):
• For RAU5x module- one fiber pair
• For RAU5x + GEM — two fiber pairs; one fiber pair for RAU5x and one fiber pair for GEM
• Grounding wire
• For RAU5x models not including external antenna – RF jumper cables from installed external antenna
