Testing Card Installation
Testing the Network
Once installed, check the on-board indicator Light Emitting Diodes (LEDs).
Normally:
•
red LED2 should be flashing, indicating network traffic from the card.
•
green LED3 should be steady ON, indicating receive activity on the
network and that your Smart Trac AC1 is an active participant in
network activities.
On-board Indicator Lights
Two LEDs on the Smart Trac Ethernet Card indicate network activity and status
information. For location, see "Appendix B – Card Layout."
