1.2 System Layout Overview
NS40s are used to form a network system known as the ImPact Intrinsically Safe Communications System.
Each NS40 is placed at a location where data, voice, and tracking applications are required.
An Intrinsically Safe network consists of a number of cells. Each cell consists of:
• A power supply unit (PSU)
• Up to four NS40s
• A pair of antennas for each 802.11b/g wireless access point
• Interconnection cables consisting of power cables, fibre optic cables, composite cables and coaxial
cables
I.S. Wireless Network Switch15Revision B
I.S. Wireless Network Switch
• Antenna splitter boxes
• Junction boxes that are used to join composite cable lengths greater than 325m.
Figure 2: An example of an Intrinsically Safe network
The Intrinsically Safe design of the network requires each cell to be individually powered and that electrical
power must not travel between them. Fibre optic cables is used to connect between cells to provide network
connectivity as shown in Figure 2: An example of an Intrinsically Safe network.
Cells can be connected in a loop configuration to provide multiple redundant network paths to the surface.
The NS40 supports Rapid Spanning Tree Protocol (RSTP), which monitors these loops and can redirect
data traffic if an active link fails.
1.3 Connectivity
The NS40 has two types of network connections:
• Composite fibre ports
• Wireless access points.
Revision B16I.S. Wireless Network Switch
I.S. Wireless Network Switch
1.3.1 Composite Fibre Ports
Each side of an NS40 unit has two composite fibre port connectors with a crush protection cover. Each
connector consists of two electrical contacts and a duplex LC single mode optic fibre (SMOF) receptacle
as shown in Figure 3: Composite fibre ports.
Note: A protective cover or a mating cable connector must be attached to each port to maintain
the IP65 (Ingress Protection) rating of the unit. Leaving a port uncovered whilst an NS40 is operating
breaches the IP65 rating and consequently the Intrinsic Safety Certification.
Figure 3: Composite fibre ports
Each port can be connected in one of the following ways:
DescriptionPort connection

Fibre optic cabling provides numerous benefits over Ethernet cabling, with superior signal integrity and
no signal interference from high powered electronics. It also enables NS40s 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.
I.S. Wireless Network Switch17Revision B

Installing I.S.Wireless Network Switches
This chapter describes mounting and installation of NS40s, antennas,
and connection of cables. Fibre plug assembly and cable termination
are beyond the scope of this manual.
Topics:
•Pre-Installation Planning
•Mounting an I.S. Wireless
Network Switch Important:
•Cables
•Antennas The electronic components in an NS40 are designed to be isolated
from the enclosure and local electrical earth. This is known as galvanic
•Before Powering Up the I.S.
Network Switch isolation and ensures there is no current passing between grounds of
different potential. In the event of a short circuit to earth, galvanic
isolation allows all devices within a cell to be intrinsically safe as there
are no loops for current to flow. Galvanic isolation must always be
maintained in the following manner:
•All NS40 circuitry isolated from the enclosure (and electrical earth)
• Use of approved Intrinsically Safe Uninterruptible Power Supply
(I.S. UPS)
• All antenna and coaxial cable connections properly insulated.
I.S. Wireless Network Switch19Revision B
2.1 Pre-Installation Planning
A detailed design study of a mine must be conducted by an MST System Engineer to determine specific
network requirements and design before installation. 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
• Access to Intrinsically Safe power
• Interconnection to the mine's existing corporate network
• Policies for network protocols between networks
• Cabling requirements
•Antenna types to use with each unit, whether antenna splitters are required, and mounting method for
each antenna
• Mounting location and installation method for each NS40.
2.2 Mounting an I.S.Wireless Network Switch
The mounting location of each NS40 should be free from debris, and should not be an obstruction to
vehicles, machinery, vent tubing, piping and cables. It can be mounted horizontally or vertically.
The NS40 has mounting points shown in Figure 5: NS40 mounting points providing several installation
options. The 10mm and 25mm diameter mounting holes allow the NS40 to be cable-tied to the mesh in
a mine tunnel. The 25mm diameter mounting holes also allow the NS40 to be secured to rock bolts in the
mine rock face.

2.3 Cables
An Intrinsically Safe network must only use approved cables for the interconnection of cells and devices.
Please consult your MST System Engineer if you have any cabling queries.
Important: Please ensure the power supply is turned off and de-energised before attaching or
detaching any cables in a cell.
2.3.1 Power and Data Cables

Extending Cable Runs with Junction Boxes
Power and data cable runs can be extended in a network using junction boxes JB10 and JB11. Junction
boxes also provide an inductance barrier, limiting current and voltage to maintain Intrinsic Safety in a
network.
The JB11 shown in Figure 7: JB11 junction box also has a DC connector. This enables separate fibre
optic and power cables to be joined to the JB11, and a composite cable run from the JB11 to the NS40.
This frees up ports on the NS40 for connecting other devices.
Figure 7: JB11 junction box
2.3.2 Coaxial cables
Coaxial cables connect an NS40's antenna ports to the antennas to transmit and receive wireless signals.
Coaxial cables connect from each of the NS40 antenna ports to either an antenna or a signal splitter, which
then connects to multiple antennas.
Use only MST approved low capacitance LMR-400-FR coaxial cable with the system.
Coaxial cable length should be kept short as possible to minimise signal loss. It is recommended to keep
cable length to less than 10 metres. The absolute maximum length is dependent on local compliance
approvals. For example, up to 50 metre coaxial cable length is approved in the U.S.A.
Important:
MST coaxial cables have connector covers that protect the exposed metal of the coaxial connectors. The
covers must be in place providing protection to an Ingress Protection (IP20) rating level and galvanic
isolation. If coaxial connectors only have metal sleeves, they must be insulated using amalgamated rubber
tape.
Installation Procedure
The following procedure demonstrates how coaxial cables are connected and insulated to the NS40.

2.4 Antennas
An NS40 has two antenna ports for each 802.11b/g wireless radio. Antennas are connected to the NS40
to optimise wireless signal coverage in the underground mining environment.
The choice of antenna will depend on wireless coverage, surrounding geology, tunnel topology and stratum
type. The antenna types used in a network are described below.
DescriptionIllustrationAntenna Type

antenna ideally suited for line of sight tunnel communications. Yagi
antennas need to be aimed accurately and avoid obstacles
in their RF beam path.
Note: Only approved antenna models can be connected to the NS40. Please consult your MST
System Engineer for any queries.
2.4.1 Antenna Placement and Layout
Antennas are usually mounted separately from an NS40 to optimise transmission and avoid any obstructions
in a mine tunnel. An antenna splitter can be used connect two antennas to a single antenna port. This
provides greater flexibility in the configuration and placement of antennas to improve wireless coverage.
Antenna placement is dependent on the surrounding geology, tunnel topology and stratum type. Antennas
can be configured in different layouts to achieve different RF patterns.
The following considerations in the placement of antennas are described and illustrated below.

Understanding VLANs
This chapter explains the principles behind Virtual Local Area
Networks (VLANs). It is important to understand VLANs to properly
configure an NS40.
Topics:
•Understanding Trunk and
Access Ports A VLAN is a collection of nodes grouped according to their function
or application, rather than their physical location. They are grouped
•Wireless MAC VLAN Bridge
•Native VLAN in order to separate and prioritise data within a network. In the context
of NS40 devices, VLANs are created to separate multiple applications
such as voice, process control, data and video in a mining network.
Figure 8: An example of two VLANs distributed across three
switches
Figure 8: An example of two VLANs distributed across three switches
shows two VLANs distributed across three network switches. PCs can
only communicate to other PCs, and MinePhones can communicate
to other MinePhones because they are on the same VLAN.
I.S. Wireless Network Switch29Revision B
3.1 Understanding Trunk and Access Ports
When VLANs are enabled, network switch ports are assigned to be either trunk ports or access ports.
These two types of port allocations determine how data is transmitted and relayed.
3.1.1 Trunk Ports
Trunk ports provide a connection for multiple VLANs between network devices and access points. They
will only transmit frames (packets of data) that belong to the assigned VLANs. To identify the frames, a
network switch will add a tag (known as an 802.1Q tag) to the frame. The tag contains the following
information:
•VLAN ID — allows the network switch receiving a frame to identify the VLAN it belongs to for
distribution.
•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. If
the switch has devices connected via access ports on the same VLAN, the tag is removed and sent those
devices. If the switch has other trunk ports that have the VLAN as a member, the frame is sent with the
tag intact.
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 creating VLANs, see Defining VLANs on
page 61.
3.1.2 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 belonging to the
assigned VLAN. Any tagged frames sent to an access port will be dropped.
3.1.3 Port Allocation
Any physical ports on the NS40 can be configured to be a trunk port or access port using the web browser
interface. The NS40 default configuration has fibre ports 1-4 allocated as trunk ports as they are usually
connected to other NS40s. For more information on defining ports , see Configuring Composite Fibre
Ports on page 58.
3.2 Wireless MAC VLAN Bridge
VLANs on the wireless network are configured as MAC based VLANs. This means that a wireless device
belongs to a VLAN based on its MAC address. A MAC Address Table specifies which MAC addresses
belong to a VLAN. If a wireless device has a MAC address that is not defined to a particular VLAN, any
frames sent from the device will be allocated to the default VLAN. The MAC address tables and default
VLAN can be configured in the web browser interface as described in Configuring Wireless MAC VLAN
Bridge Settings.
An example of a wireless network is shown in Figure 9: An example of Wireless MAC VLANs.
Revision B30I.S. Wireless Network Switch
Understanding VLANs
Figure 9: An example of Wireless MAC VLANs
3.3 Native VLAN
Trunk ports on an NS40 support a native VLAN. The native VLAN capability allocates untagged frames
received on trunk ports to be associated with the Infrastructure VLAN. This allows client devices such
as PCs or laptops to access and manage an NS40.
An example of the native VLAN capability is illustrated in Figure 10: An example of the native VLAN
capability and described below.

Composite Cable Testing
This appendix describes fibre optic cable continuity and testing in the composite cable. Fibre optic cable
testing includes visual inspection and power loss testing.
C.1 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.
1. Attach a fibre optic cable to the visual tracer and look at the other end to see if light is transmitting
through the fibre.
2. If there is no light, there is a damaged or broken section of the fibre component 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.
C.2 Measuring and Testing for Power Loss
Measuring power and loss requires a Optical time-domain reflectometer (OTDR) with a suitable custom
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.
A guideline on power losses are shown in the table below.

Connecting a PC to an I.S.Wireless Network Switch
This Appendix specifies how to set up and connect a PC (with a Windows XP operating system) to the
ImPact NS40.
In an existing network, a PC can be connected by an Ethernet cable to the surface network switch. The
network switch either incorporates or is connected to a media converter which converts Ethernet cabling
to fibre optic cabling to the NS40s. Alternatively a PC can use a media converter to directly connect to
the port of an NS40, with a power supply connected to another port.
Note when connecting fibre cable to the NS40, composite fibre port 1 is the default upstream port. The
fibre transmit (Tx) and receive (Rx) configuration is wired differently to the downstream ports as illustrated
in Figure 41: NS40 Fibre port wiring configuration.
Figure 41: NS40 Fibre port wiring configuration
Procedure
1. Connect a PC to an NS40 as described above. If the PC is already part of the network, note its TCP/IP
configuration settings.
2. Click Start > Control Panel. Open Network Connections.

Discovering Devices on the Network
The Ubicom Device Manager is a PC software application used to detect devices and configure their IP
addresses. It is used when firmware upgrades on NS40 units have reset default IP settings. The tool should
be run on a PC connected on the same network segment as the device.
Note: The management CPU in an NS40 responds to the Device Manager tool. A PC running the
tool must be on the Infrastructure VLAN.
To use the Device Manager to discover / configure device IP settings:
1. Locate and open the folder on your PC where the Device Manager tool is located.
2. Double-click the UbiDevman icon to launch.
3. The Ubicom Device Manager window is displayed and an automatic scan is initiated. Click the Scan
icon at any time to re-scan the network for devices.
4. Note the MAC address to identify the network device to edit, and click on the row to highlight it.
5. Click on the Configure icon. The IP Address Properties dialog box is displayed.
I.S. Wireless Network Switch75Revision B
6. Select the Use the following IP address option button and fill in the IP address, Subnet mask and
Default settings.
7. Click OK to close the dialog box and save changes. The Device Manager will rescan devices on the
network.
8. Select File menu and Exit or click [X] to close the Device Manager tool.
Note:
UbiDevman keeps running in the background after it is closed on PC's with Windows Vista and 7
operating systems. Shut it down from the Windows Task Manager before running it again.
