For safety of personnel and protection of equipment observe these precautions when installing, operating or servicing the equipment and surrounding areas.
3. General Warnings
Electrical
Power Supply – cord fitted for AC or DC. DO NOT adapt to a different configuration.
Power supply circuits carry high voltages. Remove rings, watches, and other jewellery before working with this type of equipment.
Batteries – Certain installation of this equipment require working with lead acid batteries, batteries present chemical, electric and gaseous hazards. Batteries are not supplied by
IPWireless for the Node B equipment although UPS systems may be coupled with the device in order to provide back up power in case of power outages.
Physical
Weight – Each Node B weighs 25kgs (55 pounds). Precautions should be taken, depending on the installation site conditions, in lifting and hoisting the device.
Environmental
There are different precautions to take within each environment. Specific precautions are listed in the installation section for that environment.
Site Location
The NodeB basestation is designed to be installed in restricted access locations only. The site locations are accessible by suitably trained service/installation personnel only.
Network Connections
The NodeB basestation is not suitable for direct connection to Public Switched Networks.
This means that the Node B is not suitable for direct connection to TNV circuits

Node B Installation Guide
4. Overview
Node B is the European Technical Standards Institute’s (ETSI) name for the radio base station. The basic function of the Node B is to convert 100 Base T packet data into the
UTRAN TD-CDMA air interface used between the Node B and the 3G Modem. The Node B can be configured to operate in configurations ranging from a single sector or omni mode, up to a 6 sector arrangement. One Node B is required for each sector of coverage, in the case of an omni configuration one Node B will be required. The Node B is controlled by an INC
(Integrated network Controller) Generally co located at the site in a separate cabinet.
The Node B supports both 768 mega chips (10MHz) and 385 mega chips (5MHz) without any hardware modification.
Scope
This document covers the physical installation and mountint of the NodeB using bracketry supplied. It does not detail custom or specialised installations or applications.
Additionally, antenna rigging/mounting, lightning protection, tower work, feeder installation / termination are all considered to be outside the scope of this document.
If in any doubt about the suitability of this document to successfully install at the proposed location, then please consult IPWireless technical support for assistance.

6. Installation
This section describes the steps to be followed to physically install the Node B.
Step 1- Pre-Installation
This section describes the initial checks that should be carried out to ensure that preparation for the installation is complete.
For Installation Check Card please see Appendix A at the back of this manual.
1. Review site construction drawings to determine if site was constructed according to the drawings.
2. Review drawings and actual installation to determine location of Node B installation.
3. Check availability of electrical, grounding and antenna connections.
4. Complete site survey.
5. Check structural strength of wall, pole or mounting frame to support Node B weight of 25Kgs (55lbs).

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 that site acquisition or permission has been granted.
Table 6-4 : Site Preparation Checklist
# Facility
1 Mains power supply –48Vdc
2 Availability of suitable Ethernet, E1, T11, E3 or T3 Interfaces
Complete
Yes/No
3 connections and trunking/conduits for interfaces
4 Suitable earth
5 Structure suitable to mount the NodeB
6 Clearance around the NodeB for cable entry and cooling
- see figure below
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 and earthing, has been done, 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
Depending on the flatness of the wall the bracket can either be mounting directly to the wall or can be mounted offset from the wall using 'Unistrut'.
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.
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 where it can be easily accessed via the front access cover.
The Node B will need to be connected near the feeder terminations and earthing points as provided on site.
Note: 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. 10 or 100 Mbps / full / half duplex as the Node B and INC may need to be configured manually in order to support this configuration.

Node B Installation Guide
General Considerations
The following consideration and checks are applicable to all mounting types :-
Ø
Consider the earthquake zone requirements for the given site being considered and ensure that the mounting arrangement and location complies.
Ø
Review the GPS installation guidelines (Step 7) 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.
Ø
Depending on the installation it may be required to fit the cable conduit to the cable glands prior to mounting Node B to the bracket.
Ø
There should be a minimum clearance of 1m above and below the Node B.
Ø
Ensure that the wall or mounting surface is sufficiently strong to support the
Node B and structure.
Ø
The Node B should be upright to permit adequate heat dissipation.

Step 4 Mounting Bracket Installations
There are three ways of installing the Node B:-
Ø
Wall,
Ø
Pole
Ø
Rack Mounts.
This section explains how to mount the Node B bracket in all three instances. The securing of the Node B to the mounting bracket is the same for the three mounts and shall be described in step 10.
Mounting Bracket
The figure below illustrates the key features of the mounting bracket.
