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 may 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 – The RF or Digital shelves of the Rack Node B can weigh up to 15kgs (33 pounds)
each depending on configurations. Precautions should be taken, depending on the
installation site conditions, in lifting and general handling the device.
Environmental
There are different precautions to take within each installation situation. Specific
precautions are listed in the installation section for that situation.
Site Location
The NodeB Rack Mount 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 Rack Mount 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.

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 possibly 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 mounting of the Node B Rack Mount in a
rack installation. It contains the specific mounting requirements for installing within a rack ut
does not contain specifications for the rack.
Where the Node B Rack Mount is required to be installed in an outdoor configuration, the
specific requirements for the outdoor enclosure are listed.
The manual 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.

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 Complete
Yes/No
1 Mains power supply –48Vdc
2 Availability of suitable Ethernet, E1, T1, E3 or T3 Interfaces
3 connections and trunking/conduits for interfaces
4 Suitable earth
5 Rack or cabinet 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 with a rack or cabinet
The digital and RF shelves of the rack mount may be mounted on a single shelf/shelf
support as a pair (Figure 6-4) or can be mounted into the rack on separate shelves or
shelf supports (Figure 6-5).
The RF shelf needs to be on the top with the digital shelf beneath. The maximum vertical
distance between the shelves shall be not more 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.
The Node B directly connected to the INC 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
as 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. 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.

Version 0.0.3 Page 20 of 39
General Considerations
The following consideration and checks are applicable to all mounting types :-
The NodeB rack mount is designed for indoor use only refer to Table 5-1.
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 5-1 & 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 or multiples.
The Node B requires un-restricted airflow front for air inlet to the rear for air exhaust.
