Step 3 Site Preparations for Node B Installation
The section specifies the facilities that need to be available at the site prior to installation. The
table below is a site checklist that should be completed prior to installation.
It is assumed that the site has already been selected from RF network planning and site
acquisition/permission has been granted.
Table 5-5 : Site Preparation Checklist
# Facility Complete Y/N
1 Mains power supply –48Vdc plus breaker.
2 Availability of suitable Ethernet, E1/T1, E3/T3 Interfaces
3 Connections and trunking/conduits for interfaces
4 Suitable earth
5 Rack or cabinet suitable to mount the Node B
6 Clearance around the Node B for cable entry and cooling
Note: if installed within enclosure/cabinet rack the
environment for the Node B must meet the requirements as
specified in Table 5-1.
Assumptions
It is assumed that prior to Node B installation all civil, electrical distribution, structured
cabling termination work has been completed.
Additionally, all antenna rigging, feeder runs and terminations, associated lightning
protection plus grounding is complete, with certification for safety / compliance issued as
required by local regulations.
It is also strongly recommended that all VSWR plots of the feeder / antenna installations
should be available for inspection.
Positioning the Node B with a rack or cabinet
The Control and Radio Equipment shelves may be mounted on a single shelf/shelf
support as a pair (Figure 5-3) or can be mounted on separate shelves/supports.
For the V5A and V5C illustrations the 1 or 3 RF shelves are shown on top with the
Control shelf. The Control shelf may be be positioned on top with the Radio Equipment
shelves as shown in Figure 5-4.
The maximum vertical distance between the shelves should not be greater than 1U
(44mm or 1 ¾”).
Selection of a suitable position for the Node B shall be done by surveying possible sites
with regard to the availability of facilities i.e. power, relative position to the INC and
consulting the site plans.
Where the Node B is directly connected to the INC ie co-sited with the INC, the Node B
should be sited not more than 100m from the INC using Shielded Category 5 Ethernet
cable as specified.
Care should be taken to position the Node B for easy front and rear access.
The Node B will need to be connected near the feeder terminations and earthing points
provided on site.
Where the Node B is installed using a microwave link ensure that the microwave link can
support the Ethernet requirements for the IUB interface i.e. 100Base-T or 10Base-T full /
half duplex as the Node B and INC. If not the Node B and INC may need to be
configured manually to support different configuration. Note: 100Base-T full duplex is
recommended.

General Considerations
The following consideration and checks are applicable to all mounting types :-
The V5 Node B is designed for indoor or weather-proof enclosure use only - refer to
Table 4-1.
Review the GPS installation guidelines (step 12) to ensure that the location will allow
proper operation of the Node B GPS remote antenna. i.e. a Southern Exposure is
required for outside installations (Northern Hemisphere), a GPS repeater may be
necessary in areas where the active GPS antenna cannot reach.
There should be a minimum clearance of 100mm in front and behind the Node B rack
mount (Figure 4-1 & Figure 5-2) for cable routing, air intake/exhaust and access to fans
at the rear.
Ensure that the rack or cabinet is sufficiently strong to support the Node B and other
equipment that may be installed with it.
The Node B requires un-restricted airflow at the front for air inlet and to the rear for air
exhaust (see figures 5-1 & 5-2).
Air filtration for the Node B environment should be specified at the cabinet/enclosure or
building level see table 5-1 for specification.
V5 Node B Installation Guide
Version 1.0.6 Page 24 of 44
Step 4 Mounting Installations
This section explains how to mount the Node B Rack Mount shelves into racks.
Mounting Rack
The figure below illustrates the 19inch mounting rack plus support shelves, some racks or
cabinets can use support rails. This construction can be within an enclosure or cabinet.
The support shelves or rails are specific to the rack, enclosure or cabinet being installed,
thus their specification shall be part of same selection.
Support shelves are required for easy of installation and support of the weight of the V5
Radio Equipment and Control shelves.

1000BaseT Connection - (Eth)
Terminate the Ethernet cables with RJ45 connectors and the cables may be secured to the
brackets on the face of the Control Shelf (Figure 5-13). Test the continuity for the Ethernet cables
with test equipment consisting of a main and a remote unit.
The termination for these interfaces is specified within the datasheets for the interfaces. The
specification for both cables should be CAT5 - 4 pair, screened cable, recommended Alcatel
LANmark-5 F2TP or equivalent.
Notes: Points to remember when installing Category 5 cables for the Node B 1000Base T
Ethernet Backhaul.
1. Do not kink the cable as the pairs are twisted to support 100MHz operation and splitting the
pairs could reduce the performance of the cable.
2. When installing the RJ45 plugs onto the cable ensure pairs are untwisted to the minimum
and that the cable sheath is clamped within the connector. Again this is to ensure the
performance of the cable is not reduced.
The pin-outs for the external Ethernet interfaces are given in the following table & figure.

Step 10 Antenna Cabling - Installation
Antennae and coaxial cable should be available at the site, and are part of the construction
checklist and general assumptions.
Two antennae per Node B Radio Equipment Shelf are optimum, allowing receiver diversity and
transmit diversity (note: if option fitted), therefore two coaxial cables per Node B are needed.
Diversity can be via polarization, in which case two feeder runs to the same antenna are needed,
feeding oppositely polarised sectors in the same physical enclosure.
Cables should be properly marked to indicate what antenna the coaxial cables are to be
connected to the Node B serving the sector or area.
In the case where only one feeder / antenna is being used, this must be connected to the top
connector when viewed from the front of the Node B. The unused port shall be terminated with a
50 load.
The following installation describes the position of the antenna ports and designations.

Step 11 Alarm Connections
If local alarms are to be utilised one D-type connector is provided with the Node B Control
shelf. The specifications for those interface requirements are below:-

Alarm Inputs
There are five external alarm inputs are connected via the 15wayD male type located on the
Control Card of the Control shelf.
The maximum input voltage is restricted to 12V and 2.5mA with a minimum
working voltage of 6V. All five input circuits are the same.
The external alarm inputs are opto-isolated current loops. The voltage and currents shall be
supplied by the external source.
The pin-out for the alarm inputs are shown in the table below.

Step 12 GPS Installation & Operation
The Node B has an external/remote GPS antenna and receiver. The connection for the
antenna (N-Type) is located on the Control Shelf, Figure 5-17.
The GPS timing signal is used by the Node B for the TDD frame timing, so that all Node B's
in a network are synchronized. The GPS signal is also used by the master oscillator for a
frequency reference. The Node B can operate for two hours after a loss of GPS timing but a
gradual drift of the frame timing will result in system interference and a loss of Node B
selection / reselection capability.
A suitable Node B GPS antenna is shipped with every Node B. This antenna should be used
with a total cable attenuation of minimum 8dB to maximum 25dB with male N-type
connectors at each end. By example cable RG6 8dB 30m and 25dB 90m. For long runs,
the cable losses will affect signal strength and could impede GPS signal performance.
For proper operation of the GPS receiver, the Node B GPS Antenna must have a clear
southern view of the sky (northern hemisphere installations). A site survey should be done
before Node B installation to verify that the Node B installation location is suitable for GPS
reception.
A simple survey method is to take a handheld GPS receiver to the site and verify that GPS
lock is obtained in the location of the Node B installation. The handheld GPS should be able
to obtain a "locked" condition within 2 minutes of power-on, and should be able to see a
minimum of 4 satellites at all times.
The GPS receiver, integral to the Node B Control shelf, is automatically enabled when the
Node B is powered and there are no adjustments or settings to be made by the user.
Note: When the Node B installation is on or near a tower or building wall, the GPS survey
should replicate the configuration.

Step 13 TTLNA Interfaces
Each V5 Radio Equipment shelf can support a TTLNA, the power and control are provided
through the Antenna Coax connections.
Notes:
1. RF and Control cables to the TTLNA should not be disconnected while the Node B is
transmitting.
The lightning protection on the TTLNA interfaces is 8kV/20mS to K21-ITU specification.
If further protection is required then shall be added separately at the cabinet or building
interface.
