LED Diagnostics

6.2.1.
RED LED = Power
The RED Power LED should always light up when power (AC or DC) is applied to the 3100P
Topside and the side panel power switch is in the ON position. Troubleshooting If the RED
Power LED does not light up when power is applied, check the position of the side panel
ON/OFF switch and all power connections to the unit. If the RED Power LED does not light up
when power is applied, but the YELLOW LED still lights up to indicate system initialization, the
most likely cause is that the RED Power LED or its own circuitry is faulty, in which case the rest
of the system might still be fully operational.
Tip: Listen for cooling fan activity inside the unit to determine if the unit is fully powered.
Tip: Discover 3100 Software provides diagnostics for 3100P Portable Topside power levels.
6.2.2.
GREEN LED = System Ready
The GREEN System Ready LED lights up solidly, and remains on, when the system is ready to
run. On startup, the GREEN System Ready LED is off while the system performs power-on
selftests. If any of these self-tests fail, the GREEN System Ready LED remains off. If all self-
tests pass, the GREEN System Ready LED lights up and remains on. Since these power-on self-
tests also test the Tow Vehicle interface, the Tow Vehicle must be attached to the 3100P Portable
Topside for these power-on self-tests to pass.
Troubleshooting:
If the GREEN System Ready LED never lights up, but stays OFF permanently, check the Tow
Vehicle cabling. If a problem is found and corrected, then cycle power to run the power-on self-
tests again.
6.2.3.
YELLOW LED = Ping
The YELLOW Ping LED lights up during startup to indicate that the system is initializing. After
the system has initialized the yellow light turns off. The YELLOW Ping LED flashes while the
