Fibre optic cabling provides numerous benefits over Ethernet cabling, with superior signal integrity
and no signal interference from high powered electronics. It also enables units to be spaced over
longer distances without the distance limitation of Ethernet cabling.
By default, port 1 is configured as the upstream port and ports 2, 3 and 4 as the downstream ports.
The difference between upstream and downstream ports is the orientation of the fibre that is used for
transmitting data and the fibre used for receiving data. This is illustrated in Figure 4: Fibre orientation
of Upstream and Downstream ports.
Figure 4: Fibre orientation of Upstream and Downstream ports
Due to the difference in the fibre orientation, MST composite cable and fibre optic cable can only be
connected between ports on NS50 devices marked with a tick in the matrix below.

Single- and Multi-Mode Cables
The NS50 is supplied from the factory with 1000BASE-LX single-mode SFP modules. Customers
wishing to interface to other cable standards, e.g. 100BASE-FX single or multi-mode, should contact
MST to arrange replacement of the appropriate SFP modules.

NOTE: If replacing the single-mode SFP modules with multi-mode modules, the singlemode patch
lead between the SFP module and the MST Composite Cable connector on the inside
of the housing needs to be replaced with a multi-mode patch lead.
JB11 junction boxes can be connected inline between any two units in the chain to
supply power. There is no need to isolate NS50 units to a single power source.
IMPORTANT: If an SFP is changed, the device must be rebooted or reset to detect
the change.
1.3.2 Ethernet Ports
The NS50 has four external Ethernet ports, that enable connection to other networking devices.
The four Ethernet ports also provide IEEE 802.3af PoE (Power over Ethernet) injector functionality,
allowing a single cable to be used for data and power to network devices. Each Ethernet port's
functionality can be configured by the web browser interface, or by centralised configuration
management. For more information on configuring Ethernet ports, see Configuring the VLAN Port
Map on Page 79.
1.3.3 Wireless Access
Wireless connectivity in each NS50 is implemented using a WAC (Wireless Access Card), consisting
of a wireless network processor and an integrated mini PCI 802.11b/g adapter.
A NS50 can contain up to two WACs. The WAC contained in the first radio card slot (on the left side)
also acts as the management CPU for the switch processor. As such, it is mandatory that this WAC is
fitted to each unit. The WAC operational parameters can be configured through the web browser
interface or by centralised configuration management. For more information, see Configuring
Wireless Radio on page 63 and Editing Site Configuration Files on page 91.

Determining Distances between Wireless Network Switches
This chapter describes network system design for underground mines.
A MST System Engineer will usually design and preconfigure a network based on the requirements
and layout of each mine site. This will involve a visual inspection of the mine site to identify user
areas, and determine access point locations. A RF (Radio Frequency) site survey is also conducted
to understand the behaviour of radio waves in the mine. The following factors help determine network
design:
Wireless coverage requirements of the mine
Quantity and type of wireless client devices connected to the network
Wired client devices connected to the network and their location
Interconnection to the mine's existing corporate network
Policies for network protocol between networks
Cabling requirements

Chapter 2: Network System Design
2.1 Installation Types and Coverage
Wireless network coverage can be described as:
Wi-Fi hotspot — Network coverage is provided in key areas, such as crib areas and refuge bays.
Full coverage — Seamless wireless coverage by strategically placing NS50 units so their radio
fields overlap.
A NS50 can communicate at wireless distances of 150-300 metres, depending on the geometry and
geology of the mine.
2.2 Power Requirements
The power requirements for a network are unique to each site installation. Determining power
requirements can be complex and is dependent on various factors such as the number of NS50 units,
PoE devices, branches in the network and composite cable lengths.
NOTE: A site inspection conducted by a MST System Engineer will help determine
the power requirements for your network.
The NS50 is designed to operate at a wide voltage range, from a minimum of 8VDC up to 54VDC.
Each NS50 in a network can internally step up the incoming voltage to 48VDC in order to supply
power to its connected PoE devices. The NS50 needs to receive a minimum input of 15VDC to power
PoE devices.
48VDC power supplies are used for large networks to maximise the distance between power
supplies. For smaller networks of 1-2 nodes, it is recommended that a lower voltage 24VDC power
supply is used.
External power supply recommendations:
- AC to DC power supply with galvanically isolated output(s).
- 48VDC output(s) (nominal)
- With 6A breaker / fusing in line with each 48V output.
2.3 Choosing Antennas
Antennas are connected to each NS50 to provide wireless network coverage. The type of wireless
coverage, surrounding geology, tunnel topology and stratum type are factors that will determine the
choice of antenna. A minimum of one antenna is required per WAC in a NS50.
Antennas consist of two directional patterns:
Omnidirectional antennas — radiate equally in all directions for a short range, providing
immediate coverage in an open area.
Directional antennas — radiate in a specific direction over a longer range. A higher gain antenna
will have a longer range and is more directional. It is important that directional antennas are
aligned properly between NS50 units to ensure continuous coverage between units.
The antenna radiation pattern and polarisation need to be considered to provide suitable wireless
coverage in an area.

Antennas commonly used with the NS50 are shown below.
Antenna Type
Illustration
Description
Omnidirectional 5.5dbi
rubber whips
A lower gain antenna that radiates equally in all
directions. It provides direct coverage in an open area.
Panel antenna
A panel antenna is a directional antenna, with a wide
horizontal beamwidth and narrower vertical
beamwidth. They are suited for covering an open area
in one direction.
Diversity panel antenna
A diversity panel antenna contains two panel antennas
in one housing with a 90° rotation between them. It
is used for providing better signal reception in difficult
areas, and more accurate AeroScout tag location when
Wi-Fi tracking is implemented. Diversity antennas
use both antenna connections on a WAC.
Yagi directional antenna
A Yagi antenna is high gain directional antenna. They
are ideally suited for line of sight tunnel
communications. Yagi antennas need to be aimed
accurately and avoid obstacles in their RF beam path.
2.4 Placement of NS50 Units
A site inspection will determine the best positioning of cables, NS50 units and antennas prior to
installation. NS50 units with antennas directly attached should be mounted in an elevated position,
within line-of-sight of mobile devices. Ideally this would be situated high up on a tunnel ceiling or on the
rock wall face. The mounting location should be free from debris, and avoid obstruction to vehicles,
equipment/machinery, vent tubing and cables.
NS50 units should not be installed in cut-out areas such as safety bays and remuck bays, due to
signal confinement. In such instances, a WAP is more suitable, connected to the nearest NS50. For
details on common NS50 mounting scenarios, see NS50 Mounting Options on page 15.
2.5 Placement of Antennas
Antennas are usually mounted separately from each NS50 to optimise transmission and avoid any
obstructions in a tunnel. They are connected by coaxial cable. The coaxial connection should be kept
as short as possible to minimise signal attenuation. Larger antennas / longer cable feeds can require
line amplifiers, and possibly bi-directional splitter / combiners for dual antenna systems.
Antenna placement is dependent on the surrounding geology, tunnel topology and stratum type. The
recommended placement of antennas is as follows:
Tip 1: Directionality
Antennas should be mounted and angled to give optimum transmission along curves and dips as
shown below in Figure 5: Angling antennas.

Tip 2: Obstructions
Antennas should be mounted to avoid signal obstruction from rock, vehicles, equipment and
machinery as shown in Figure 6: Antenna mounting to avoid obstructions.

The positioning of the antennas is crucial when AeroScout tags are used for asset tracking and
location services. AeroScout tags will not be read when there are antenna standing wave nulls.
Antennas need to be positioned to have best reception of tag messages. For Antenna mounting

2.6 Determining Distance between Wireless Network Switches
Line of Sight Distances
In line of sight, each NS50 has a maximum wireless range of 300 metres (984 feet) using high gain
directional antennas. NS50 units are generally installed with a 100 metre (328 feet) overlap of the
radio field as shown in Figure 8: Wireless channel layout and distances Distances Around Curves
This ensures sufficient coverage between NS50 units.
NS50 units within range of each other must be configured with different Wi-Fi channels. By default
every fifth channel is used (channels 1, 6 and 11) to prevent signal overlap, minimising the possibility
of inter-modulation or interference.
Figure 8: Wireless channel layout and distances Distances Around Curves
The wireless range of a NS50 decreases when going around curves. In this case, NS50 units need to
be installed closer together to provide sufficient coverage. Distances between NS50 units will vary
depending on the drift and tightness of the curve. They are installed closer together on a tight curve.
Use the following steps to estimate the distance between NS50 units:
1. Install one NS50 unit at the beginning of the curve.
2. Install the second NS50 unit between 20 metres (65 feet) to 40 metres (130 feet) from the
end of the curve.
3. Install and align antennas.
4. Perform a RF signal strength test by walking from the first NS50 to the second NS50.
5. If the strength test records levels of:

-80dBm to -65dBm, the NS50 units are spaced for optimal coverage.
-81dBm to -100dBm, move the second NS50 closer (at 10m intervals), and conduct another
RF signal strength test.
-64dBm to -10dBm, move the second NS50 further away, and conduct another RF signal
strength test.

3.4 Connecting Power to the NS50
A pre-deployment power-up test of NS50 units is recommended. To conduct a power-up test:
1. Connect the composite fibre/power cable to a DC power source with correct termination.
Note that the DC supply must be between 10 and 50VDC. Refer to the power supply
requirements Section 2.2.
2. Turn on the DC power supply and verify that the green power light is on. If there is no
green light, refer to Troubleshooting Guide on page 104.
Power can be applied to cabling whilst additional NS50 units are being installed. Power usage levels
should be evaluated prior to adding more units downstream to ensure that the voltage rail does not
drop too low. A minimum of 15VDC is required for a NS50 to supply PoE to other devices. If the
voltage drops below 15V, additional power is required.
3.5 Handling Composite Cable During Installation
The composite cable is ruggedly built for the mining environment. However the following
precautionary measures should be noted during installation:
Never pull or create tension on the cable. Unreel the cable from the cable reel, or allow the weight
of the cable to unreel as the vehicle is moving as shown in Figure 13: Handling composite cable.
Do not bend the cable at sharp angles; excessive bending can fracture or break the fibre optic
cable.
Do not step on the cable.

VLANs and Wireless Networks
Native VLAN
This chapter explains the principles behind a Virtual Local Area Network (VLAN). It is important to
understand VLANs to properly configure the wireless network switch.
A VLAN is a collection of nodes grouped according to their function or application, rather than their
physical location. They are grouped in order to separate and prioritise data within a network, as shown in
Figure 14: VLANs. VLANs are created when multiple applications, such as voice, telemetry, data and
video, are required in a mining network.

NS50 wireless network switch
User Manual
Revision C
Chapter 4: Understanding VLANs
4.1 Understanding Trunk and Access Ports
VLANs can be assigned to trunk ports and access ports on a network. These two types of allocation
determine how data is transmitted and relayed.
4.1.1 Trunk Ports
Trunk ports typically provide a connection between network switches, and can carry data for multiple
VLANs. They will only transmit frames (packets of data) that belong to the port's assigned VLANs. To
identify the VLAN of each frame, a network switch adds a tag to the frame (known as 802.1Q trunking).
The tag contains the following information:
VLAN ID — allows the network switch receiving a frame to identify the VLAN it belongs to.
Priority ID — allows the network switch to prioritise distribution when multiple frames are being
transmitted. Priority ID ranges from 0-7, where 7 is the highest priority.
When a network switch receives a tagged frame, the tag is read to determine the VLAN it belongs to. The
tag is removed and distributed to devices connected on the same VLAN.
When the network switch receives multiple frames, it will prioritise the distribution of frames based on the
Priority ID in the VLAN ID tag. For more information on configuring VLANs, see Defining VLANs on page
77.
4.1.2 Access Ports
Access ports connect client devices such as PCs and laptops to the network switch, and can only be
assigned to a single VLAN. Access ports can only send and receive untagged frames, with those frames
allocated to the relevant VLAN inside the switch. Any tagged frames sent to an access port will be dropped.
An example of VLAN traffic flow through trunk and access ports is shown in Figure 15: VLAN traffic flow
and described below.

Figure 15: VLAN traffic flow
1. A PC sends an untagged frame into access port 6 (Control VLAN) on wireless network
switch 1. The frame is sent to other access ports on the Control VLAN (access port 5).
2. Wireless network switch 1 tags the frame with VLAN ID = 4 and Priority = 5 and sends it
through the trunk ports to Wireless network switch 2.
3. Wireless network switch 2 receives the tagged frame, and identifies the frame belonging to the
Control VLAN.
4. Wireless network switch 2 removes the tag and sends the frame to all ports on the Control
VLAN (access ports 5 and 7).
5. If Wireless network switch 1 receives multiple frames, they are tagged and sent via trunk
ports to Wireless network switch 2.
6. Wireless network switch 2 receives the frames and prioritises distribution.

4.1.3 Port Allocation
Physical ports on the NS50 can be configured to be either a trunk port or access port using the web browser
interface or editing site configuration files when Trivial File Transfer Protocol (TFTP) is used. The NS50
default configuration has ports 1-8 allocated as trunk ports . Ports 1-4 are usually connected to other NS50
units, and ports 5-8 are connected to WAPs or other PoE devices. For more information on configuring
ports and VLAN membership, see Configuring the VLAN Port Map on page 79.
4.2 VLANs and Wireless Networks
The wireless network switch can have up to four wireless Service Set Identifiers (SSIDs) per
WAC. Each SSID is associated with a single VLAN and functions as an access port on that
VLAN. An example of a wireless network is shown in Figure 16: An example of VLAN and
wireless networks and described below.
Figure 16: An example of VLAN and wireless networks
1. An untagged frame is sent from a Laptop 1 through a wireless network (SSID = Data) on the
network switch.
2. The frame is tagged by the network switch and is sent through the trunk port to the WAP.
3. The WAP identifies the tagged frame as belonging to the Data VLAN and removes the tag.
4. The untagged frame is sent via the wireless network (SSID = Data) to Laptop 2.

4.3 Native VLAN
Trunk ports on the wireless network switch also support a Native VLAN. The Native VLAN is where
untagged frames will be allocated. On the network switch, the native VLAN is always the Infrastructure
VLAN. This allows client devices such as PCs or laptops to access and manage the network switch when
they are connected via a trunk port.
The Infrastructure VLAN is mandatory in the network switch and cannot be deleted.
An example of native VLAN functionality is illustrated in Figure 17: An example of native VLAN and
described below.

1. The PC sends an untagged frame to Trunk port 3 on wireless network switch 1.
2. The frame is allocated to the Infrastructure VLAN.
3. The management CPU of wireless network switch 1 is always an Access port on the
Infrastructure VLAN and will receive the frame.
4. The untagged frame would also go to wireless network switch 2 via the Trunk ports between
the network switch units.
5. Wireless network switch 2 allocates the untagged frame to the Infrastructure VLAN.
6. The management CPU of wireless network switch 2 is always an Access port on the
Infrastructure VLAN and will receive the frame.
7. Any frame leaving the Management CPU is placed on the Infrastructure VLAN.
8. All frames on the Infrastructure VLAN are sent out untagged on Trunk ports.

Compression, and Dynamic Turbo. This setting is backwards compatible with non-Turbo (legacy)
devices. Dynamic Turbo mode is only enabled when all devices on the wireless network are Super
AG with Dynamic Turbo enabled. In Turbo mode, the access point doubles the channel bandwidth to
increase the throughput.
Super AG with Static Turbo – Channel 6 ONLY - Capable of Packet Bursting, FastFrames,
Compression, and Static Turbo. This setting is not backwards compatible with non-Turbo (legacy)
devices. Static turbo mode is always on and is only enabled when all devices on the wireless network
are Super AG with Static Turbo enabled.
Channels
It is recommended that WACs in proximity of each other have different wireless channels (for example,
channels 1, 6 and 11). This minimises signal overlap and the possibility of interference.

Chapter 6: Centralised Configuration Management
Topics:
Devise Management Overview
TFTP Server Overview
TFTP Parameters
Centralised configuration management is an alternative configuration method to the web interface. It
uses Trivial File Transfer Protocol (TFTP) where devices read and apply configuration files from a TFTP
server. It is a faster way to configure a large number of network switches, reducing the potential for
human error.
There are two ways to take advantage of TFTP configuration:
ICA v1.4.0 or later - Device Management via the ICA Administration Console
For networks with an ICA v1.4.0 or higher, AP settings can be managed from the ICA Administration
console. A customisable Site Default template is included at installation, and further templates can be
copied from it and modified separately. Additionally, individual APs can have specific settings overridden
via the Administration Console.
In this case, the ICA will push configuration changes to the APs, and no local setup is required.
ICA v1.3.1 or earlier, and 3rd party TFTP servers - Manually editing configuration files
For older ICA systems and other TFTP servers, configuration files are edited and uploaded manually, and
APs must be configured to periodically self-check and fetch new configuration files from the server when
available.
More information about individual parameters is included in the TFTP Parameters section on page 92.

6.1 Device Management Overview
The ICA Administration Console (v1.4.0 and later) supports the creation of Access Point configuration
templates. A Site Default template is created at installation and applied to all managed devices. New
templates can be copied from the Site Default and applied to selected devices, and further overrides
can also be applied to individual devices.
Some familiarity with the ICA Administration Console is assumed here. For more information, see the
ICA Administration Console User Manual available from MST.
There are three editors in the ICA Administration Console with relevant settings:
Configuration > Site Configuration
Configuration > AP Config Templates
Devices > Access Points
6.1.1 Site Configuration
This editor contains the option to Set new Access Points as Managed - If checked, all newly discovered
Access Points will be confgured according to the Site Default template by the ICA. If disabled, new APs
must either have their management settings configured in the Devices > Access Points editor, or be
configured manually.

6.1.2 AP Config Templates
The ICA is installed with one AP Template: Site Defaults. This is a special AP Template which defines
the settings that new APs will automatically pick up if Set new Access Points as Managed is ticked in
the Site Configuration editor. This template cannot be deleted, but new templates can be copied from it
and modified separately.
NOTE: Once a template is applied to an AP, any manual changes made to settings
listed in the template will be reverted automatically to the template default. Settings
that are not defined by the template can be changed freely.
New templates are created by copying an existing template (initially the only one to copy is Site Defaults).
A copied template will start with the same parameters as the original, but they are not linked, so further
changes to one will not affect the other. To create a new template, select another template from the list
and click the Copy button. To delete a template, click the Remove button.

Figure 39: Centralised configuration management
6.2.1 Editing Site Configuration Files
Site configuration files contain common settings for all devices in a network. The site configuration file
has the naming convention ap_site_settings.conf. This file is retrieved by devices using TFTP.
NOTE: The same site configuration file can be used to configure network switch
units and WAPs in a network. When the site configuration file is applied to WAPs, all
switch port settings are ignored by the WAP.
The site configuration file can be opened on a PC and edited using a text editor. Parameters are
changed by modifying the text and saving the file. A description of the editable parameters are covered

1. Edit the parameters as required.
2. Save the site configuration file in the directory folder of the TFTP server.
6.2.2 Editing Device Configuration Files
Device configuration files contain settings specific to each WAC in the network device. A device
configuration file is created for each WAC. Device configuration files follow the naming convention
ap_MACaddress.conf where MACaddress is the MAC address of the WAC. A device will recognise
and apply the device configuration file based on a comparison of the MAC address in the file name.
Note that any parameter from the site configuration file can override parameters in a device configuration
file. However, it is recommended that only the settings that are different be entered into the device
configuration file in order to make maintenance easier.
A device configuration file configures individual settings for each device as shown below. The device
configuration file can be edited using a text editor such as Wordpad or Notepad. The example below
includes settings that are commonly over-ridden. All other settings are inherited from the global site
configuration file. Comments are prefixed with a hash symbol (#) and are ignored by the device. These
are not necessary for configuration but may be included for convenience.

Appendix B:
Composite Cable Testing
This appendix describes fibre optic cable continuity and testing. Fibre optic cable testing includes visual
inspection and power loss testing.
B1: Visual Inspection of the Fibre Optic Cable
Fibre optic cable can be inspected by visually tracing and inspecting the connector.
Visual Tracing
Checking for continuity diagnoses whether the fibre optic cable is damaged or broken. A visible light
"fibre optic tracer" or "pocket visual fault locator" connected to a fibre optic connector.
Attach a fibre optic cable to the visual tracer and look at the other end to see if light is transmitting
through the fibre.
If there is no light, there is a damaged or broken section of the fibre in the composite cable.
Visual Connector Inspection
A visual inspection of the fibre optic termination is usually carried out using a fibre optic microscope. It is
important the fibre termination has a clean, smooth, polished, and scratch free finish. Any signs of
cracks, chips or dirt will affect connectivity.
B2: Measuring and Testing for Power Loss
Measuring power and loss requires a Optical Time-Domain Reflectometer (OTDR) with a suitable adapter
matching the fibre optic connector being tested.
To measure power in fibre optic cable:
1. Set the OTDR to ‘dBm’ and set the wavelengths according to the fibre optic cable being
tested.
2. Attach the OTDR to the fibre optic cable at the receiving end to measure the output.
3. Compare the output with a reference test cable.
To measure power loss in fibre optic cable:
1. Set the power meter to ‘dB’ for a relative power range and select the wavelength required for
the test.
2. Perform a single-ended loss test by connecting the cable to be tested to the reference cable and
measuring power loss at the receiving end.
3. Perform a double-ended loss test by attaching the cable between two reference cables that
are attached to the source and to the OTDR. If high losses are measured, reverse the cable
and test in the opposite direction using the single ended test.
