3.7.2.3 Activating The System
To activate the 3100-P Portable Sub-Bottom Profiling System after making all necessary connections:
1. Operate the ON/OFF switch to the ON position (switch position = UP).
Figure 3-6: Portable Processor Case Interface
NOTE:
The ON/OFF switch operates in both the AC and DC power input
modes.
2. Observe the side panel LEDs. The desired LED status for normal operation should be:
Power RED = ON
System Ready GREEN = ON
Ping (transmit) YELLOW = OFF or FLASHING
3. The LEDs on the topside processor should display the following under normal circumstances:
RED LED = Power
The RED Power LED should always light up when power (AC or DC) is applied to the 3100-P Topside
and the side panel power switch is in the ON position.
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.
NOTE: Listen for cooling fan activity inside the unit to determine if the
unit is fully powered.
