3. Trace the DC input from the source (battery) and check the following:
That a 12VDC Input from the source (12VDC Automotive Battery) is being
applied to the High Current System ON/OFF Switch, and the High Current
Barrier Strip. Verify the following
10AWG wire is used between the battery and the high-current barrier strip
10AWG wire is used between the high-current barrier strip and the
distribution barrier strip.
4. Verify that 22AWG wire (Positive and Negative) is routed from the barrier strip to
the Garrett Ethernet Switch.
5. Verify that positive and negative 18AWG wire is routed from the barrier strip to the
DC input of the Gateway Router. If mounted outdoors, ensure power connection is
shielded for outdoor use.
6. Verify that positive and negative 18AWG wire is routed from the barrier strip to the
DC input of the MMR System.
7. Verify that positive and negative 18AWG wire is routed from the barrier strip to the
DC input of the Gateway Server.
9.2 System Operation
The following procedure is provided to allow the installer/operator to verify proper
system operation in a simple straightforward manner. Troubleshooting is included within
the body of this procedure. When reading the procedure you will notice information
within a heavily bordered box. This information is applicable only when the operator
does not get the desired result at a given step. In these instances, the operator shall adhere
to the information within the bordered area. When the resulting actions are complete the
operator shall continue performance of the steps outside the bordered area. Information
within these borders shall be ignored as long as the desired result for each step is taking
place.
1. Power up the system by placing the high-current system on/off switch to the On
position.
2. The GW Router will power up. At the time of printing this document, the only way to
confirm power to the GW router is by connecting a laptop to the Ethernet switch and
“pinging” the GW Router. Installations that take place in the near future will include
a new GW Router that has a group of indicators on the bottom of the unit. The PWR
indicator can be observed in order to verify that power is applied to the GW Router.
3. Is the GW Router the only DC powered device that is not powered up?
Troubleshoot the wiring between the DC power supply and the GW Router
and, if necessary, make wiring repairs. Otherwise replace the GW Router.
The GW Server will be powered up. Power to the GW Server can be confirmed by
