5.10 Ignition of Flammable Atmospheres

Warnings for Use of Wireless Devices

Observe all warning notices regarding use of wireless devices.

Potentially Hazardous Atmospheres

Observe restrictions on the use of radio devices in fuel depots, chemical plants, etc. and areas where
the air contains chemicals or particles, such as grain, dust, or metal powders, and any other area
where you would normally be advised to turn off your vehicle engine.

Safety in Aircraft

Switch off the wireless device when instructed to do so by airport or airline staff. If the device offers
a ‘flight mode’ or similar feature, consult airline staff about its use in flight.

Safety in Hospitals

Wireless devices transmit radio frequency energy and may affect medical electrical equipment.
Switch off wireless devices wherever requested to do so in hospitals, clinics, or health care facilities.
These requests are designed to prevent possible interference with sensitive medical equipment.

Pacemakers

Pacemaker manufacturers recommended that a minimum of 15cm (6 inches) be maintained
between a handheld wireless device and a pacemaker to avoid potential interference with the
pacemaker. These recommendations are consistent with independent research and
recommendations by Wireless Technology Research.

Persons with Pacemakers:

n Should ALWAYS keep the device more than 15cm (6 inches) from their pacemaker when

turned ON.

n Should not carry the device in a breast pocket.

n If you have any reason to suspect that the interference is taking place, turn OFF your device.

Configure Ethernet interfaces

To configure an Ethernet interface, you must configure the following items:

Required configuration items

n Enable the Ethernet interface. The Ethernet interfaces are all enabled by default.

Additional configuration options

The following additional configuration settings are not typically configured to get an Ethernet
interface working, but can be configured as needed:

n A description of the Ethernet interface.

n The duplex mode of the Ethernet interface. This defines how the Ethernet interface

communicates with the device to which it is connected. The duplex mode defaults to auto,

which means the TransPort LR device negotiates with the connected device on how to

communicate.

n The speed of the Ethernet interface. This defines the speed at which the Ethernet interface

communicates with the device to which it is connected. The Ethernet speed defaults to auto,

which means it negotiates with the connected device as to what speed should be used.

From the command line

1. Enable the Ethernet interface. By default, all of the Ethernet interfaces are enabled.

eth 1 state on

2. Optional: Set the description for the Ethernet interface. For example:

eth 1 description “Connected to DSL WAN router”

TransPort LR User Guide 28

Interfaces

3. Optional: Set the duplex mode.

eth 1 duplex {auto | full | half}

4. Optional: Set the speed.

eth 1 speed {auto | 1000 | 100 | 10}

Cellular interfaces

The TransPort LR device has two cellular interfaces, named cellular1 and cellular2. These cellular
interfaces correspond to the physical SIMcard slots SIM1 and SIM2 respectively.

Both cellular interfaces cannot be up at the same time. If both cellular interfaces are enabled to on,
then cellular1 interface takes precedence.

A typical use case would be to have cellular1 (SIM1) configured as the primary cellular interface and
cellular2 (SIM2) as a backup cellular interface. If the TransPort LR device cannot connect to the
cellular network using SIM1, it will automatically failover to try to connect using SIM2.

For the TransPort LR device to automatically configure a default route for the cellular interface when
it is up and for it to be able to failover to and from the cellular interface, it must be assigned to a WAN
interface.

Configure cellular interfaces

To configure a cellular interface, you need to configure the following:

Required configuration items

Enable the cellular interface. By default, the cellular interfaces are disabled.

n The Access Point Name (APN). The APN is specific to your cellular service.

n Depending on your cellular service, you may need to configure an APN username and

password. This information is provided by your cellular provider.

n Assign the cellular interface to a WAN interface. For more information on the WAN

configuration, see Wide Area Networks (WANs) on page 52.

Additional configuration options

Additional configuration settings are not typically configured, but you can set them as needed:

n Preferred mode. The preferred mode locks the cellular interface to use a particular

technology, for example, 4G or 3G. Depending on your cellular service and location, the cellular

interface can automatically switch between the different technologies. You may want to lock

the cellular interface to a particular technology to minimize disruptions.

n A description of the cellular interface.

TransPort LR User Guide 32

n Connection attempts. This is the number of attempts the cellular module will attempt to

connect to the cellular network before indicating a failure. It defaults to 20, but you may want

to configure this so that the WAN failover can switch to another interface more quickly.

From the command line

1. Enable the cellular interface.

cellular 1 state on

2. Configure an APN.

cellular 1 apn your-apn

3. If necessary, configure the APN username and password.

cellular 1 apn-username your-apn-username

cellular 1 apn-password your-apn-password

4. Optional: Set a preferred mode.

Interfaces

cellular 1 preferred-mode 3G

5. Optional: Set a description for the cellular interface.

cellular 1 description "AT&T Connection"

6. Optional: Configure the number of connection attempts. For example, to set the number of

attempts to 10, enter:

cellular 1 connection-attempts 10

Configure DSL

To configure the DSL interface to connect to your DSL network, you need to configure the following:

Required configuration items

n Enable the DSL interface.

n Virtual Path Identifier (VPI) and Virtual Circuit Identifier (VCI) parameters. These parameters

are specific to each DSL provider and must be configured to match your provider’s settings.

n Data encapsulation for the DSL interface. This parameter is specific to each DSL provider and

must be configured to match your provider’s settings.

n Username and password. The username and password relate to your account with your DSL

provider. A password is not always needed.

Additional configurable options

The following additional configuration settings are not typically configured to get the DSL interface
connected to the DSL network, but you can set them as needed:

n The technology used on the DSL line, known as the line mode.

n The Maximum Transmission Unit (MTU). The MTU defines the maximum size (in bytes) of a

packet that can be sent over the DSL interface.

n Network Address Translation (NAT).

n A description of the DSLinterface.

n Whether to delay bringing up the DSL for a specified number of seconds. This delay allows the

DSL provider network to propagate network changes after the device has connected to the

network, and before packets can be sent and received. This delay prevents the device from

assuming the network is fully operational before it actually is fully operational, which could in

turn cause problems with other features, such as interface failover. During this delay, the

DSLLED flashes, to indicate the interface is not fully up. Because characteristics can differ

among provider networks, use of the delay-up parameter is provider-specific.
