You can confirm activation by watching the Comm LED to see if it goes solid. You may also confirm activation by entering AT command
The activation sequence for an
LTE Verizon
modem would therefore look as follows:
The LMU must be registered on the Verizon network. Having the device roaming or in poor Verizon coverage will not allow the execution of the
activation process.
The activation is an automatic process where Verizon pushes the APN to the modem.
In some cases, there might be a delay up to 15 minutes until the unit gets activated and is able to make a data call.
For Verizon LTE, parameter 2306 (APN) is currently disabled.

Preparing for Installation
Be sure you have received all the LMU components you need. This must include:
The LMU to be installed
A power harness
24 Pin Molex I/O Connector
16 Pin Molex VBUS Connector
Optional Components:
Input and output cables
Relays
LMU peripherals (i.e. Serial adapter, jPOD, TetheredLocator)
Host serial devices (e.g. PDAs, laptops, other serial devices)

Plan The Installation
Verify Power, Ground and Ignition.
Be sure to check each source (power, ground and ignition) to ensure that the proper signaling exists. This is
typically accomplished with a multi-meter.
Before drilling any holes or running any wires, decide where each hardware component will be located (LMU, antennas, peripherals, etc.). Be sure
that the cables to the LMU are not bent or constricted in any way. Also make sure that the LMU is kept free from direct exposure to the elements
(sun, heat, rain, moisture etc...).
Be advised that an installation that violates the environmental specifications of the LMU will void the warranty.
The best way to ensure a trouble-free installation is to consider your options and make some decisions before you start. Take a look at the vehicle
and determine how to best install the LMU for the following purposes:
Accurate data gathering and simulation of how customers actually use your solution
Ongoing monitoring and maintenance of LMU equipment
Accidental or intentional alteration of the equipment or cable connections
The following sections cover some of the issues to consider when planning your LMU installation.
5.4.1
Size and Placement of LMU Unit
The dimensions of the LMU should be taken into account, particularly when installing in a vehicle:
Whether you intend to place the LMU under a seat or into a cavity behind the vehicle’s interior molded trim, be sure the LMU will fit before
drilling any holes or running cable
