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
• Antenna splitter boxes
• Junction boxes that are used to join composite cable lengths greater than 325m.
I.S. Wireless Network Switch15Revision A
I.S. Wireless Network Switch
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 pro vide network connectivity as shown in Figure 2.
Cells can be connected in a loop configuration to provide multiple redundant network paths to the surface. The NS40 supports Spanning Tree Protocol (STP), 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 A16I.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.
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
DC power only connection
Fibre only connection
Fibre and DC power 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.

Installing I.S.Wireless Network Switches

Topics:
• Pre-Installation Planning
• Mounting an I.S.Wireless
Network Switch
• Cables
• Antennas
• Before Powering Up the I.S.
Network Switch
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.
Important:
The electronic components in an NS40 are designed to be isolated from the enclosure and local electrical earth. This is known as galv anic 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 A
Installing I.S. Wireless Network Switches

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 f actors 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 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.
Revision A20I.S. Wireless Network Switch

2.3 Cables

An Intrinsically Safe network must only use approved cables for the interconnection of cells and de vices. 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

Cables terminated with a connector which attach to the NS40 ports are described in the table below:

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 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 cov ers 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 sleev es, 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
Omndirectional antenna
Diversity panel antenna
An antenna that radiates equally in all directions. It provides direct coverage in an open area.
A diversity panel antenna contains two antennas. It is used for providing better signal reception in difficult areas, and a more accurate Aeroscout tag location when Wi-Fi tracking is implemented. Diversity antennas require two antenna connections to the network switch.

Yagi directional antenna
Note: Only approved antenna models can be connected to the NS40. Please consult your MST System Engineer for any queries.
A Yagi antenna is a highly directional antenna providing a very narrow but longer horizontal beamwidth. 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.

2.4.1 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 co v erage.
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

Topics:
• Understanding Trunk and
Access Ports
• Wireless MAC VLAN Bridge
• Native VLAN
This chapter explains the principles behind Virtual Local Area Networks (VLANs). It is important to understand VLANs to properly configure an NS40.
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. In the context of NS40 devices, VLANs are created to separate multiple applications such as voice, process control, data and video as required in a mining network.
Figure 8: An example of tw o VLANs distributed acr oss three switches
Figure 8 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 A
Understanding VLANs

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 Chapter 5 "Defining
VLANs".

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 and VLAN membership, see Chapter
5 "Configuring the VLAN Port Map".

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 Chapter 4 "Configuring Wireless
MAC VLAN Bridge Settings".
An example of a wireless network is shown in Figure 9.
Revision A30I.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 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 (O TDR) 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 wa velength 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 conv erter 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 dif ferently to the downstream ports as illustrated in Figure 36.
