1.2 System Layout
NS50 units are installed in a mine to form a wired and wireless network. This section describes a simple
NS50 system layout in a mine.
The rst NS50 in a network is connected to an Ethernet switch and power supply via a JB11 junction
box. (See Connecting power to the NS50 on page 31).
Units are typically connected in series down the mine tunnel by composite cable. When the mine tunnel
splits into different sections, an additional NS50 is branched from the network. NS50 or Wireless Access
Point (WAP) devices can also be positioned in Wi-Fi ‘hot spots’ such as crib areas and refuge bays.
A PC or mobile device can connect to the network when in proximity of an NS50 or WAP.
1.3 Connectivity
The NS50 has three types of network connections:
• Composite Fibre Ports
• Ethernet Ports
