Gigabit Ethernet board Power Requirements:
The Gigabit Ethernet board
utilizes approximately 2.5 Watts of power.
•
5.0VDC input, approximately 500mA
1.3.5
Power Section Testing
NOTE: The connectors and components on the bottom of the Gigabit Ethernet board
have pins that are connected to internal supply voltages and ground. If these pins are
inadvertently shorted together or to a common chassis ground, the board fuse (F1) will
trip/reset.
If both the “+5V” LED and the “+3.3V” LED is out:
•
Check for continuity of PTC fuse F1 with an ohmmeter.
•
Replace PTC fuse if open.
If only the “+3.3V” LED is out:
•
5VDC voltage is present at the source
•
Replace the board with a spare, nothing repairable.
