3) +12 VDC Models require a rectified and filtered nominal 24V DC power source.
Voltage can range from 22 VDC to 28 VDC to allow use with a float charged battery
system. A designated 50A source with independent over current protection is
required for each IP-RAN unit (fused or circuit breaker). No other equipment should
be connected to the designated circuit breaker.
4) DC powered models require suitable cables with connector lugs to be supplied by the
installer for connection to the DC power source. A #4 or a #2 AWG gauge fine
stranded cable is recommended. Other gauges may be required depending on the
calculated voltage drop. The recommended bolted bus bar connection is a Blackburn
p/n CLT2-2516 or equivalent. Use the bolts supplied with the IP-RAN to connect to
the bus bar.
5) Proper ground connections are essential for both safety and for proper RF
performance. Racks must be equipped with either a grounded bus bar running the
height of the rack, or a common bonding point with a dedicated ground cable
connected to a common cell site ground system. Installation requires that both the IP-
RAN main unit and the RU amplifier system be connected to a common site ground
using ground straps provided with the system. The site ground system must be
independently tested and verified for low resistance to ground.
7.1.5 Verify location of LAN facilities and connection points
1) Locate the customer provided LAN connection points. This could be a dedicated
Ethernet switch, or a set of Ethernet connection points on an IP transport system
terminal.
2) The IP-RAN system requires one IP address for proper operation. RNC(BSC) and
RN(BTS) are working by one.
3) All Ethernet connection should be made using RJ-45 connectors and Category 5 or 6
Ethernet cables capable of supporting 10/100BaseT operation.
4) The static IP Address setting for the IP-RAN will be done after power up using the
web server tool (ref BSM Operations Manual). A site connection and IP addressing
diagram should be prepared for each site and posted at the site after installation.
5) It is strongly recommended that a copy of local site IP routing and addressing
diagrams be sent to AirWalk at the following address to support any remote
diagnostics needed.

7.1.6 Verify location of RF Antenna Systems, including GPS
1) Locate the site antenna systems, transmission lines and interconnection jumpers.
Follow the site interconnection diagrams provided by the RF Systems Engineer. It is
essential both for proper system operation and for regulatory or licensing
requirements that the antennas are connected to the correct sectors using the correct
jumper cables.
