NetPort IS—Configuration, Installation, and Maintenance
1 Introduction
This document describes how to configure, install, and maintain a NetPort IS access node and
how to connect it to a Northern Light Digital Network®.
The Northern Light Digital Network is a modular, durable hardware and software communications
and monitoring system for use in underground mining and tunneling operations. The network
uses a pre-engineered approach to network design and deployment, allowing the network and its
network devices to be pre-configured before deployment below and above ground. The design of
the Northern Light Digital Network meets the applicable requirements of Title 30 Code of Federal
Regulations, Part 23 and is approved for use in gassy underground mines. Approval No. 23A080010-0 is assigned by MSHA to the NL Technologies Digital Communications System.
The NetPort IS was developed to meet its specific needs where only MSHA-certified products
must be used in order to ensure the safety of miners working in dangerous conditions where
flammable gasses or coal dust is present and the risk of sparks and explosions is always a major
safety concern. In addition, the NetPort IS offers the following features:
•
Robustness and durability
•
Open and non-proprietary TCP/IP-based network architecture
•
Integrated data communications
•
Above-ground network management software for below-ground system monitoring
•
Capability for Wi-Fi tracking of personnel, specialized toolsets, equipment, and so on
•
Standby battery backup
•
Hardwired MSHA-approved fiber
•
Ethernet ring topology for redundancy
•
Capability to withstand a single-point-of-failure
•
IEC Ex or equivalent IS-certification for added safety and security
1.1 A typical network
The Northern Light Digital Network architecture is based on an open, IP-based standard network
using NetPort IS nodes, interconnected with fiber-optic cable network in a basic loop topology.
NetPort IS—Configuration, Installation, and Maintenance

1 Introduction
Figure 1— The basic network topology
The NetPort IS is an IP-based device that communicates with other nodes and devices on the
network and allows these devices to communicate wirelessly with IP-compatible, Wi-Fi client
devices deployed in the mine.
Figure 2 shows a typical network, divided into the networked equipment installed on the surface
and the equipment that is installed underground. The installation of the underground equipment
differs depending on the environmental conditions:
•
Gassy locations: The NetPort IS must be installed together with a certified, intrinsically-safe
(IS) power supply.
•
8
Fresh-air locations: The NetPort IS can be installed together with non-IS power supply.

MSHA Conditions of Use (NetPort IS access node)
Approval No. 23-A080010-0, A&CC PAR No. 0092994
•
The NetPort IS access node can be located in areas where permissibility is required
only when connected to the KH Controls Model ISS1-13.0-4.00-NL1 Power Supply, IA13827-0 installed in the KH Controls Model ISSXP, X/ P-3929-0 enclosure.
•
The Battery Backup Module Subassembly must only be replaced in a fresh-air area of
the mine.
•
All intrinsically safe cables must be run separately from non-intrinsically safe cables.
2.2 Preparing the NetPort IS node
Before you install a NetPort IS node, you must prepare the node for installation by performing the
following procedures described in this section:
•
Terminate the 12VDC power cable connected to the NetPort IS (IS installations only).
•
Connect the Battery Backup Module and ensure that the backup battery is fully charged.
•
Verify that NetPort IS has been properly configured and is ready to connect to the network.
•
Ensure that the node has been properly sealed.
Danger: The NetPort IS must be prepared in a dust-free, fresh-air environment.
When opened, the NetPort IS is not intrinsically safe.
2.2.1 Terminating the 12VDC power cable (IS installations only)
The NetPort IS comes with a 12VDC cable, pre-installed. When the NetPort IS is installed in the
mine, this cable is connected to an external power supply that converts the mine’s 120VAC
power to 12VDC. NetPort IS units installed in gassy locations must be powered by IS power
supplies. Units installed in fresh-air locations can be powered by non-IS power supplies.
These power-supply options are described in detail beginning on page 25. This section describes
how to prepare the 12V power cable so that it can be connected to IS power supplies. In non-IS
14
NetPort IS—Configuration, Installation, and Maintenance
2 Installing a NetPort IS node
installations, the cable is wired directly into the non-IS power supply and does not need to be
terminated at this stage.
To terminate the 12V power cable, refer to Figure 3 and follow these wiring instructions.
1. Before you begin wiring, position the closure plug over the housing, sliding it from the
smaller-diameter end.
2. Completely loosen the three insert assembly screws.
3. Remove the L7 male plug insert from the housing.
4. Insert the cable through the compression nut (note the conductor position), nylon washer,
grommet, and housing. Do not pre-strip the jacket or the conductors.
5. Strip cable jacket 32mm (1-1/4").
6. Strip conductors 11mm (7/16") and twist leads to eliminate possibility of stay strands.
7. Insert the stripped conductors into the wiring pockets, as shown, and torque conductor
clamp screws to 1.8 Nm (16 in. lbs.)
8. Push the insert into the housing, insuring that the insert key is aligned with the housing
keyway.
9. Tighten the three insert assembly screws.
10. Push up the grommet, washer, and compression nut; and tighten until the cable is secure.
Note: the cable jacket must extend through the end of the grommet.

2.2.2 Preparing the battery
The NetPort IS is shipped with its internal Battery Backup module disconnected. Also, although
the batteries are fully-charged when the NetPort IS leaves the factory, they may have lost some
or all of their charge in transit or in storage while waiting to be installed.
Before the NetPort IS is installed in the mine, its battery must be connected and fully charged. To
do so, follow these steps:
1. Rotate the slotted pawl latches on the enclosure cover and open the NetPort IS. Refer to the
figure below.
Danger: The NetPort IS must only be opened in a dust-free, fresh-air environment.
When opened, the NetPort IS is not intrinsically safe.

4. Verify that the green Power light on the front of enclosure cover is lit. This indicates the
NetPort IS is receiving power from the external power supply and that the NetPort IS is
operating normally. Refer to “Status lights” on page 89 for more information.
5. If the NetPort IS has not been pre-configured, do so now, following the procedures beginning
on page 51. Pre-configured nodes should be labeled with a sticker that includes each node’s
unique IP address, or you may have to consult your network plan.
6. Ensure that the battery is connected and working properly. To do so, follow these steps:
a. Wait until the external power has been connected long enough for the battery to have
been at least partially charged (approximately one hour).
b. Temporarily disconnect the external power supply.
c. Verify that the red Battery light on the front of the enclosure cover is lit. This indicates
that the NetPort IS is receiving power from the internal battery.

7. Verify that the gasket on the enclosure cover is in place and properly seated as you close the
cover and lock the pawl latches. Refer to Figure 4, below.
Note: Before you close the cover, ensure that the NetPort IS is turned on, since you cannot
open the unit in a gassy environment to access the power switch.
8. Ensure that the battery is fully charged. You have two options: you can reconnect the NetPort
IS to the local 12V power supply for 24 hours, or you can install it in the mine and allow the
battery to charge there. Note: The NetPort IS will not have full backup power until the
batteries are fully charged.

2.3.1 Mounting the NetPort IS
The method you choose to mount the NetPort IS units depends on the conditions at each location
in the mine. The NetPort IS comes with standard mounting brackets welded to the enclosure, and
Figure 5 (above) provides the measurements you need to correctly position the mounting holes
20
NetPort IS—Configuration, Installation, and Maintenance
2 Installing a NetPort IS node
for these brackets, using M8 bolts or studs. Your installation, however, may require additional
wall-mounted devices on which to mount the NetPort IS.
2.3.2 Mounting and connecting the antennas
The NetPort IS allows for the connection of two antennas per NetPort IS. These antennas provide
the 802.11b/g Wi-Fi coverage around each installed NetPort IS location. Note: You do not need to
install two antennas with each NetPort IS, but this is recommended to assist with providing
extended and more reliable coverage. Only one of the two antennas is ever used by the NetPort
IS. The NetPort IS automatically checks signal strength from each antenna and selects the
antenna with the strongest signal. Because of this, it is best to place one antenna in the location
that is judged to be best and the other offset in another location.
NL Technologies offers two types of antenna:
•
Directional (helical) and
•
Omni-directional (compact Yagi).
The antennas you choose to install on at each NetPort IS location depends on the layout of your
mine and the coverage you require. Consult your network plan.
Warning
•
The distance between the antenna and any 1 ohm electric detonator must not be
less than 33 centimeters (13 inches).
•
The coaxial cable used to connect the antenna to the NetPort IS must not be more
that 15.24 meters long (50 feet).
•
The antenna cable must be enclosed in flame-resistant hose conduit.
To install an antenna follow these steps:
1. Before mounting the antenna, check to see if it has a weep hole. This is a small hole in the
antenna casing that allows moisture to escape. Make sure this hole is pointing downwards,
otherwise moisture and dust could enter the antenna and damage it.
NetPort IS—Configuration, Installation, and Maintenance
21
2 Installing a NetPort IS node
2. Before positioning the antenna, make sure the cable length is adequate to connect to the
NetPort IS with some slack. Refer to page 85 for antenna cable specifications.
3. Antennas can be hung from a mine’s roof, mesh, service cables or mounted to a mast or the
wall of the mine using an appropriate mounting bracket. To mount an omni-directional
antenna, consult the manufacturer’s instructions. To mount a directional antenna, follow
these steps:
a. Assemble the mount and attach it to the antenna as shown in Figure 7. Loosely tighten
the bolts in the joint to allow for adjustment later.
b. Ensure that the antenna is pointing in the required direction and affix the bracket in
place. Tighten the bolts on the joint. The best location is close to the ceiling with the
antenna pointing parallel to the ceiling and straight down the tunnel.
4. Connect the antenna cable by carefully threading the cable’s connector onto the antenna’s
connector. Note: This connector has a very fine thread and it is easy to cross-thread it. Make
sure the connector is properly screwed on before attempting to tighten it down.
5. Route the cable to the NetPort IS. Loosely coil the excess cable; making the loops too tight
can cause some signal loss or even damage the cable.

2.3.3 Connecting the network cables
Warning: The fiber-optic cables installed outside the NetPort IS (field fiber) must meet
the specifications described in “Fiber-optic cables” on page 86.
Each NetPort IS location should already be equipped with two fiber-optic network cables. These
cables must be terminated by a certified installer, using LC connectors, and following the
instructions contained in Tyco Electronics Instruction Sheet #408-10079.

2 Installing a NetPort IS node
To connect these network cables to the NetPort IS, follow these steps for each cable:
1. Remove the protective caps from both of the fiber conductors at the end of the cable. Figure
7 shows a typical fiber-cable plug with both caps removed.
Figure 8— Fiber cable plug
2. Insert the fiber cable plug into one of the fiber receptacles (fiber ports) at the bottom of the
NetPort IS cabinet, as seen in Figure 6, and twist the coupling ring to the right until the plug
is locked into place. (It does not matter which port you choose for each cable.)
Note: The fiber plug consists of two LC connectors labeled Rx and Tx. Make sure to align the
plug so that its Rx connector plugs into the Tx socket in the receptacle, and that the Tx
connector plugs into the Rx socket.

3 Installing the external power supply
The external power supply receives 120 VAC input and provides 12 VDC output to power the
NetPort IS. NLT offers two kinds of external power supplies: a non-IS power supply for fresh-air
locations, and an IS power supply for gassy locations.
This chapter describes how to connect these power supplies to the mine’s 120VAC
infrastructure, and how to connect the NetPort IS to the 12VDC power supply.

3 Installing the external power supply
The non-IS power supply requires you to terminate the AC and DC cables inside the power
supply’s enclosure.
For the IS power supply, NL Technologies offers two options for installing the AC cable: (i) with an
external receptacle to receive the AC input; and (ii) with a packing gland on the AC cable that
requires you to terminate the cable inside the power supply’s enclosure. The DC output from
each of these models is provided through an external DC receptacle.
•
To install and mount a non-IS power supply (part number DT4500), refer to the instructions
beginning on page 27. These include the instructions for terminating the DC cable from the
NetPort IS inside the power supply’s enclosure.
•
To install and mount an IS power supply with an AC receptacle (part number DT4501),
refer to the instructions beginning on page 33. These include instructions for terminating the
AC cable with the appropriate female line plug.

4 Powering up the network
This chapter describes how to power up a network of NetPort IS access nodes.
4.1 Preliminary precautions
After installing all NetPort IS access nodes, verify the following connections prior to powering up
the network:
•
Power supplies to 120VAC supply.
•
Power supplies to NetPort IS access nodes.
•
Antennas to NetPort IS access nodes.
•
NetPort IS access nodes to fiber network. Verify that RX endpoints are connected to the TX
endpoints, and that the TX endpoints are connected to RX ones.
•
Underground network to above-ground Northern Light Digital Network.
Before attempting to power up the system, verify that:
•
All NetPort IS enclosures and power supplies have been mounted as indicated in the network
design.
•
Each NetPort IS is connected to at least one antenna using the supplied antenna cable. (A
second antenna is optional.)
•
Each directional antenna is pointing in the correct direction.
•
The disconnect switch on all IS power supplies is in the ON position. Non-IS power supplies
do not have an external switch.
4.2 Powering up the network
After all the above preparations have been made, each NetPort IS can be powered up by turning
on the AC power to each location.
4.3 Testing procedures
Once you’ve powered up the network, follow these procedures to verify each unit is operating
normally, that it is communicating with other nodes in the network, and that it is transmitting and
receiving Wi-Fi signals:
NetPort IS—Configuration, Installation, and Maintenance
49
4 Powering up the network
1. Verify that the green Power light on the front of enclosure cover is lit. This indicates the
NetPort IS is receiving power from the external power supply and that the NetPort IS is
operating normally. Refer to “Status lights” on page 89 for more information.
Figure 18 — Status lights
2. Verify that the two blue Ethernet lights are both flashing or steadily lit.
3. Disconnect each fiber-optic cable, one at a time, and verify that data can still reach this
NetPort IS. One of the Ethernet lights should continue to flash or remain steadily lit
(depending on the network traffic), while the light that monitors the cable you disconnected
should remain off. Note: When you disrupt the network in this way, you may experience a
delay of up to 60 seconds before proper communication is restored.
4. Ping all nodes and all PLC/Modbus clients to confirm the connections. This is done from the
above-ground workstation.
5. Verify that the blue WLAN light is flashing and that your Wi-Fi client devices are connected
and communicating correctly with the NetPort IS.
50
NetPort IS—Configuration, Installation, and Maintenance
5 Configuring the NetPort IS
Each NetPort IS on your network must be configured with its own, unique IP address. If your
network has been pre-configured, each NetPort IS should be labeled with a sticker that includes
its IP address, or you may have to consult your network plan.
If the network has not been pre-configured, this chapter describes the procedures for configuring
a NetPort IS. You may also use the same procedures should you need re-configure a node, as
described in “Troubleshooting and maintenance” beginning on page 65.
5.1 Establishing a connection
The NetPort IS node is configured using a command-line interface. You can establish a
connection to the node over the network (provided you know the IP address for that node, or you
can connect directly to the node using the RS422 port inside the enclosure.
Warning: To configure the NetPort IS through its RS422 port, you must open the
enclosure. The NetPort IS node must only be opened in a dust-free, fresh-air
environment.
5.1.1 Connecting over the network
It is also possible to connect to an NetPort IS node over an existing network if its configuration is
partially known. The important detail is the IP address. Any IP address associated with the
NetPort IS node can be utilized. To establish a connection, use Telnet or SSH, depending on your
security settings. We recommend Putty, which is an application that supports either protocol and
can be downloaded at no charge from the following website:
http://www.putty.org
The NetPort IS uses the default TCP ports for these protocols: port 23 for Telnet; port 22 for SSH.
The NetPort IS node is VLAN-aware, according to the 802.1Q IEEE specifications. This means that
the whole NLT Digital Network can be divided into smaller logical groupings. For example, all NLT
Messenger devices can connect to one VLAN, while all PLC devices can connect to another VLAN.
NetPort IS—Configuration, Installation, and Maintenance
51
5 Configuring the NetPort IS
This allows information to be segregated on the network, allowing easier and faster traffic
prioritizing and filtering.
When configuring the NLT IS Node, each interface can only be associated with one VLAN. The
NetPort IS node supports up to four virtual interfaces, and therefore supports up to four separate
VLANs.
Configuration on the NetPort IS node is based on configuring individual Basic Service Sets (BSS).
Each BSS corresponds to one wireless network. As such, each wireless network will have its own
set of configurable options. This includes options such as SSID and encryption details, but does
not include IP addressing.
5.1.2 Using the RS422 port
To configure the NetPort IS using the RS422 port, follow these steps:
1. Set your terminal (or a computer running a terminal application) to the following
specifications.
Baud rate
115,200
Bits
8
Stop bits
1
Parity checking
None
Error checking/correction
None
2. Attach your terminal to the RS422 connector shown in Figure 19, labeled J7 on the printedcircuit board. If necessary, use an RS422-to-RS232 adaptor.

5 Configuring the NetPort IS
Figure 19 — The RS422 port
Power switch
RS422 connector J7
5.2 Default settings
The NetPort IS node ships with a default configuration which must be changed before use. The
default IP address is 192.168.0.1, and a default wireless network is also set up but disabled.
Generally this default network will need to be deleted, which can easily be completed by running
the following command:
del bss 0
5.3 Scenario A
In this scenario, the NetPort IS node is required to broadcast two separate wireless networks,
each on their own VLAN. The details are defined below:
Generic NetPort IS node settings:
•
IP address: 172.25.0.1
NetPort IS—Configuration, Installation, and Maintenance
53
5 Configuring the NetPort IS
•
Subnet mask: 255.255.0.0
Settings for first wireless network:
•
SSID: “Messaging”
•
Security: WPA with pre-shared key
•
Passphrase: “NLT_Mining”
Settings for second wireless network:
•
SSID: “Monitoring”
•
Security: WEP
•
WEP Key: “ABCDE12345”
To configure this scenario, first set up the IP address and subnet mask, since these are not
related to a wireless interface:
wlan[0,0]-> set ipaddr 172.25.0.1
wlan[0,0]-> set ipmask 255.255.0.0
We then need to add some default wireless settings:
wlan[0,0]-> set wirelessmode 11b
wlan[0,0]-> set dualap 1
A new wireless network, or BSS, must be added:
wlan[0,0]-> add bss
This creates the first wireless network, named “Messaging.” This network must now be selected
as being the one to be configured:
wlan[0,0]-> config bss 0
54
NetPort IS—Configuration, Installation, and Maintenance
5 Configuring the NetPort IS
The appropriate settings must now be set. For further information on the different options
available, see the instructions beginning on page 56.
wlan[0,0]-> set ssid Messaging
wlan[0,0]-> set encryption enable
wlan[0,0]-> set authentication WPA-AUTO-PSK
wlan[0,0]-> set passphrase NLT_Mining
This completes the set up of the first wireless network. A second wireless network (BSS must be
added:
wlan[0,0]-> add bss
Select this new network as the active network, so changes in settings apply to it. Note how the
prompt changes to indicate which BSS is being configured:
wlan[0,0]-> config bss 1
wlan[0,1]->
Set the appropriate settings:
wlan[0,1]-> set ssid Monitoring
wlan[0,1]-> set authentication auto
<mapping sub-ioctl authmode to cmd 0x8BE0-3>
wlan[0,1]-> set key 1 40 ABCDE12345
wlan[0,1]-> set key 1 default
Next save the changes to memory:
wlan[0,1]-> commit
Restart the access point to make the changes take effect:
wlan[0,1]-> reboot
NetPort IS—Configuration, Installation, and Maintenance
55
5 Configuring the NetPort IS
5.4 Scenario B
In this situation, the NetPort IS node from the previous network must have it’s IP address
changed from 172.25.0.1 to 172.25.0.5. In addition, the “Messaging” network is being renamed
to “Messenger.”
First, set the new IP address:
wlan[0,0]-> set ipaddr 172.25.0.5
Check setting:
wlan[0,0]-> get ipaddr
ipaddr: 172.25.0.5
Then, select the “Messaging” network:
wlan[0,0]-> config bss 0
Check the original setting to make sure the correct network is being changed:
wlan[0,0]-> get ssid
ssid: Messaging
Set the new SSID:
wlan[0,0]-> set ssid Messenger
Save and restart:
wlan[0,0]-> commit
wlan[0,0]-> reboot
5.5 Configuring hardware settings
5.5.1 Dual Ethernet
set dualenet option
56
NetPort IS—Configuration, Installation, and Maintenance
5 Configuring the NetPort IS
This enables or disables the use of the second ethernet device. Requires rebooting the NetPort
IS. The options can be “enable” for enable or “disable” for disable. For example the following
enables the second ethernet device.
set dualenet enable
5.5.2 Dual Access Points
set dualap option
This enables or disables the use of the second wireless device. Requires rebooting the NetPort
IS. The options can be “enable” for enable or “disable” for disable. For example, the following
disables the second wireless device.
set dualap disable
5.6 Configuring IP settings
5.6.1 Setting the IP address
set ipaddr address
Sets the IP address of the NetPort IS node to address. For example, to set the IP address to
172.25.0.1:
set ipaddr 172.25.0.1
5.6.2 Reading the IP address
get ipaddr
Shows the current IP address of the NLT IS Node. For example,
wlan[0,0]-> get ipaddr
ipaddr: 172.25.0.1
5.6.3 Setting the subnet mask
set ipmask mask
NetPort IS—Configuration, Installation, and Maintenance
57
5 Configuring the NetPort IS
Sets the subnet mask of the NetPort IS node to mask. For example, to set the subnet mask to
255.255.0.0:
set ipmask 255.255.0.0
5.6.4 Reading the subnet mask
get ipmask
Shows the current subnet mask. For example:
wlan[0,0]-> get ipmask
ipmask: 255.255.0.0
5.6.5 Setting the Wireless Mode
set wirelessmode mode
This sets the wireless mode to mode, that is, it selects the frequency and operating bandwidth.
The first column of the table below lists the various values that mode can take, and the second
column shows the respective details of that mode. Note that the NetPort IS node as a whole must
use one single mode; separate interfaces cannot use different modes.
Wireless mode
Description
auto
Auto select
11b
802.11b mode (2.4GHz, 11Mbps)
11g
802.11g with 802.11b compatibility (2.4GHz 54Mbps)
108g
802.11g Dynamic Turbo mode (2.4GHz 108Mbps)
For example, to set the mode to 802.11b mode, which runs at 2.4GHz and provides up to
11Mbps:
set wirelessmode 11b
<mapping sub-ioctl turbo to cmd 0x8BE0-1>
58
NetPort IS—Configuration, Installation, and Maintenance
5 Configuring the NetPort IS
Note also that the NetPort IS software defaults to 802.11a mode which operates at 5GHz. While
this mode can be selected, the hardware does not support it so it cannot be connected to. This
default mode must be changed to allow any wireless network to be usable.
5.6.6 Reading the Wireless Mode
get wirelessmode
This shows the current mode that the interface is operating at. Use the table from the previous
section to translate a mode into a description. For example:
wlan[0,0]-> get wirelessmode
Wireless LAN Mode: 11b
From the table, we can see that “11b” means that the NetPort IS is using the 802.11b standard,
using 2.4GHz and providing up to 11Mbps.
5.6.7 Creating and configuring a wireless network
add bss
This command adds a new wireless network which can be configured. It will usually be referred
to as “BSS 0” but this depends on how many wireless networks you have configured. If a
wireless network only needs to be reconfigured, not created fresh, then this command is not
required.
All of the below options only apply to the current wireless network (BSS). Therefore, a wireless
network must be selected before running any of the following commands.
config bss number
Selects the wireless network number as the active network. For example, to set the active
network to BSS 0:
config bss 0
NetPort IS—Configuration, Installation, and Maintenance

5 Configuring the NetPort IS
5.6.8 Setting the SSID
set ssid name
Sets the SSID to name. For example, to set the SSID to NLT_Mining:
set ssid NLT_Mining
5.6.9 Reading the SSID
get ssid
Shows the current SSID of the selected network. For example:
wlan[0,0]-> get ssid
ssid: NLT_Mining
5.6.10 Setting the authentication

NetPort IS—Configuration, Installation, and Maintenance
5 Configuring the NetPort IS
For example, to set the mode to WPA with pre-shared key
set authentication WPA-PSK
5.6.11 Reading the Authentication
get authentication
Shows the current authentication mode. Refer to the table above for the description. For
example:
wlan[0,0]-> get authentication
authentication: open
From the table, “open” refers to the Open-System WEP authentication mode.
5.6.12 Setting the WEP key
set key number length key
Sets the WEP key with index number to have a length of length, and sets the actual key to key.
•
The index is generally 1, but can also be 2, 3 or 4 as WEP supports 4 different keys.
•
The length designates how long, or how many characters, are in the key. It can take values
of 40 (for 10 characters), 104 (for 26 characters) or 124 (for 31 characters). The number
designates how many bits in the key.
For example, to set the first code to “ABCDE12345”:
set key 1 ABCDE12345
Up to 4 different keys can be set, and the network needs to know what key to use. This is set as
follows
set key number default
NetPort IS—Configuration, Installation, and Maintenance
61
5 Configuring the NetPort IS
This sets the default key to number, where number is the index used to create the key. Note that
the key must be created before it can be set. For example, to set key 1 to be default:
set key 1 default
5.6.13 Reading the WEP key
get key
This shows all WEP keys that have been set, as well as the default key. For example:
wlan[0,0]-> get key
key 1: 12345ABCDE
default key index: 1
5.6.14 Setting the WPA passphrase
set passphrase key
This sets the WPA passphrase to key. The passphrase must be at least 8 characters long, and at
most 63 characters long. For example, to set the passphrase to “MiningUnderground”:
set passphrase MiningUnderground
5.6.15 Setting the VLAN
set pvid vlan
This sets the VLAN associated with this wireless network to vlan. It must be a number between 1
and 4095 inclusive, and must be the same for every device on the same VLAN. For example, to
set the VLAN ID to 5:
set pvid 5
5.6.16 Reading the VLAN
get pvid
This shows the current VLAN ID associated with the wireless network. For example:
62
NetPort IS—Configuration, Installation, and Maintenance
5 Configuring the NetPort IS
wlan[0,0]-> get pvid
pvid: 5
5.6.17 Setting the Encryption
set encryption option
This sets whether encryption is to be used on the selected wireless network. This is required for
any form of security. The options are “enable” or “disable”:
set encryption enable
5.6.18 Reading the Encryption
get encryption
This shows whether encryption is enabled on the wireless network. For example:
wlan[0,0]-> get encryption

6 Troubleshooting and maintenance
The NetPort IS is designed for a long life and low maintenance. The units are easy to upgrade
and new software is easy to install. And since each NetPort IS enclosed in a tough stainless-steel
shell, there is little chance of damage.
Should you encounter a problem with one of your NetPort IS units, this section contains
instructions that will help you track down and solve the problem, together with a guide to userserviceable parts and how the components of the NetPort IS interact.
This section is not, however, intended as a comprehensive guide to diagnosing and repairing a
NetPort IS, and instead should primarily be used in emergency situations where experienced
personnel trained in the network’s operation are not available. It may provide you with enough
information to perform quick repair procedures, but these repairs should always be verified by
experienced personnel at a later time.
Warning: Should a procedure require you to open the NetPort IS enclosure, you must
first relocate the unit to a dust-free, fresh-air environment. When opened, the NetPort
IS is not intrinsically safe.

Should a NetPort IS shut off unexpectedly or if the network shuts down, refer to the following
diagnostic procedures to help you identify the and solve the problem.
Note: The following diagnostic procedures are intended to be only a guide in providing suggested
solutions to the most common NetPort IS and networking problems. For best results, contact your
NLT maintenance and support personnel who can provide immediate assistance by remotely
accessing the network through a VPN (Virtual Private Network) and connecting directly with the
system to diagnose the actual problem.

6 Troubleshooting and maintenance
6.1.1 Problems with the NetPort IS
The Power light on the NetPort IS is off
In a normally operating, powered-up NetPort IS, the green Power light, located on the front of the
NetPort IS enclosure, should be brightly lit. This indicates that the external 12VDC power supply
is powering the NetPort IS, and that the NetPort IS is connected properly and operating. If the
Power light is not lit, this suggests that there is no DC current coming to the NetPort IS. In this
case:
•
Check the power switch inside the NetPort IS to verify that the switch is turned on.
Note: This must be done in a fresh-air location.
Power switch
•
Check that the external power supply is properly connected and undamaged.
•
Contact NL Technologies Technical Support.
The Battery light does not light when the AC power is off
When the AC power goes down, the NetPort IS should automatically switch to its internal backup
battery for power. When the NetPort IS is being powered by its internal battery, the red Battery
light, located on the front of the NetPort IS enclosure, should be brightly lit. If the Battery light
66

6 Troubleshooting and maintenance
does not light, this suggests that the Carrier Board is not receiving DC power from the internal
batteries. In this case:
•
Check that the battery cable is connected to connector J3 on the Power Path Switch.
Note: This must be done in a fresh-air location.

Contact NL Technologies Technical Support.
Ethernet 1 or Ethernet 2 status lights are not lit
Flashing Ethernet lights indicates that there is traffic between a node and its neighboring nodes,
while a steady light indicates that the corresponding fiber cable is connected to the fiber port but
that there is no traffic. If one of these lights is not flashing or steadily lit, do the following:
•
Check the corresponding cable connector at the bottom of the NetPort IS to verify that it is
tight and properly seated.
•
If the connector is properly seated, and the light remains off, then it may be a defective fiber
cable. Troubleshoot the fiber cable.
•
Contact NL Technologies Technical Support.
The network software applications do not detect the NetPort IS.
•
Verify that the NetPort IS is receiving power: either the green Power light or the red Battery
light, located on the front of the NetPort IS enclosure, should be brightly lit. If neither are lit,
follow the trouble-shooting procedures beginning on page 66.
68
NetPort IS—Configuration, Installation, and Maintenance
6 Troubleshooting and maintenance
•
Verify that the Ethernet 1 and Ethernet 2 status lights are flashing or steadily lit. If not, follow
the trouble-shooting procedures in the previous section.
•
Recheck and re-install the configuration parameters for that NetPort IS.
•
Contact NL Technologies Technical Support. There may be a defect in the Carrier Board or
the Abicom Processor Board.
The NetPort IS does not respond during attempts to
remotely view its operations
To verify connectivity, ping the NetPort IS using a remote diagnostic tool such as Ping, Traceroute
(trace/rt), SNMP, or Telnet. If you receive no reply, the NetPort IS may possibly be dead and need
replacing, there may not be a network connection at the NetPort IS, or the IP address for that
NetPort IS may have been improperly entered. Rectify this by re-establishing a network
connection or by re-configuring a new IP address.
6.1.2 Network connectivity problems
The Northern Light Digital Network is configured in an Ethernet ring topology. This allows the
network to recover from a single point of failure in the network. Should a failure occur, traffic
traveling in one direction is routed in the other direction on the ring so that it reaches the
destination node. The network cannot recover from a two-point failure; any NetPort IS between
the failed parts of the network will not be reachable.
Damage to the fiber, failure of the connectors,
or defective fiber board (transceiver)
If a fiber run is defective it must be replaced. If a connector has failed, the fiber run must be reterminated. If a fiber board (transceiver) is defective, it must be replaced; refer to the parts list on
page 75 (part number DT0315-S or DT0315-M).
Incorrect fiber cable connections.
•
The plug at the end of the field fiber cables consists of two LC connectors labeled Rx and Tx.
Ensure that the Rx connector on the plug is plugged into the Tx socket in the receptacle and
that the Tx connector is plugged into the Rx socket. If not, reverse the connection.
NetPort IS—Configuration, Installation, and Maintenance

6 Troubleshooting and maintenance
6.1.3 Data Communications
Failure of data communications can be much more complex than a simple break somewhere in
the system. Diagnostics must be performed by a competent, NLT-approved network engineer.
6.1.4 Antennas
The antennas are very robust and NLT has never had the helical antenna type fail. If the weep
hole is facing down, as it should be when correctly installed, moisture will not enter the interior
of the antenna. It has not yet been established if rock dust can enter the weep hole and cause
any kind of problems for the antenna.
Damaged antenna
If an antenna is damaged mechanically, such as, for example, being struck by a mining vehicle, it
will have to be replaced. If a dual-antenna setup is used, the second antenna will continue to
function.

6.2.1 Replacing the 12VDC cable
To install a new 12VDC cable in a NetPort IS, follow these steps:
Warning: Before opening the NetPort IS enclosure, you must first relocate the unit to a
dust-free, fresh-air environment. When opened, the NetPort IS is not intrinsically safe.
1. Open the NetPort IS enclosure.
2. Remove the old 12VDC cable, making note of its connections to the Power Path Switch
circuit board inside the NetPort IS (see Figure 25, below) and the configuration of the gland
through which it passes at the base of the NetPort IS enclosure.
Figure 25 — 12VCD screw terminals and cable polarity

Screw terminals
3. Thread the new cable through the gland at the base of the enclosure, up the inside wall and
across the top of the cabinet so that the connectors can reach the terminals on the Power
Path Switch circuit board.
4. Identify the positive and negative screw terminals on the Power Path Switch. See Figure 25,
above.
5. Connect the positive (black) wire to the positive terminal.
6. Connect the negative (white) wire to the negative terminal.

Appendix C Status lights
The status lights are located on the front of the NetPort IS cabinet, as shown below. These lights
indicate when a NetPort IS is functioning correctly and are a useful diagnostic tool should you
encounter problems with your network, as described in “Troubleshooting and maintenance”
beginning on page 65.
Figure 28 — Status lights
Power (green): A steady light indicates that the NetPort IS is receiving power from the external
12VDC power supply, and the batteries are in standby mode.
Battery (red): When the external power supply is down, a steady light indicates that the NetPort
IS is receiving power from the internal backup supply (batteries).
WLAN (blue) : A flashing light indicates that there is wireless traffic between the NetPort IS and
one or more Wi-Fi clients. A steady light indicates that the WLAN interface is functioning but that
there is no wireless traffic.
Ethernet 1 and 2 (blue): Flashing lights indicates that there is traffic between this node and its
neighboring nodes. A flashing light on Ethernet 1 indicates that there is traffic in the fiber cable
connected to Fiber Port #1. A flashing light on Ethernet 2 indicates that there is traffic in the fiber

cable connected to Fiber Port #2. A steady light indicates that the corresponding fiber cable is
connected to the fiber port but that there is no traffic.
Serial (blue): During normal operation this light is OFF. The light blinks only when the serial port
is being used during configuration and troubleshooting.
