3) Connect the external GPS antenna to the IP-RAN GPS antenna input. Use a suitable
RF cable (RG-58 or equivalent) equipped with a TNC connector.
4) Connect the external RF antenna systems. Follow site specific cable installation
drawings prepared by the RF system/planning engineer for cable type and routing.
The IP-RAN unit is equipped with N-type RF connectors. Ensure the individual sector
antenna systems are connected to the correct IP-RAN sector antenna connections.
Incorrect sector connections may cause operational or coverage problems.
5) AC Models Only: Connect the AC line cords for the IP-RAN a dedicated AC power
source.
Only use the cables provided with the system for continued safe operation.
6) DC Models Only: Locate and verify the polarity of the DC power source cables. Slip a
4” length of heat shrink tubing over each DC cable. Connect the cable lugs to the
RPSU DC power bus bars using the supplied connector lug bolts. Tighten the bolts
firmly to ensure a solid electrical connection. The use of electrical contact grease is
acceptable if desired. Slide the heat shrink tubing over the bus bar connection and
use a heat gun to secure the connection.
Short circuits in high current DC power systems can be dangerous. All exposed DC
connections must be protected to prevent accidental short circuits.
7.2.4 Power-up procedure
Verify all connections are correct prior to powering up base station.
1) AC Models Only
a. Switch on the AC power source.
b. Switch on the IP-RAN main unit power switch located on the rear panel power
entry point. The switch is located adjacent to the DC PWR connection.
2) DC Models Only
a. Switch on or engage the circuit breakers at the +12 VDC power source.
b. Switch on the RPSU main circuit breaker located on the RPSU front panel.
c. Use the RPSU voltmeter to verify the presence of +24/27 VDC power.
d. Switch on the RPSU RU circuit breaker located on the RPSU front panel. Note
the increase in current consumption on the RPSU current meter.
e. Switch on the IP-RAN main unit (AW-100) circuit breaker located on the RPSU
front panel. Note the increase in current consumption on the RPSU current
meter.
3) The IP-RAN unit will automatically initiate the startup procedure.
4) Verify communication between the IP-RAN main unit and the RU amplifier system by
observing the communications indicators (led MST) on the RU front panel. The
indicators should on to indicate communication is occurring.
