Figure 2-9. SERIAL/ETHERNET I/O Page
The SERIAL/ETHERNET I/O Page displays Ethernet communication statistics. If Ethernet communication
issues are suspected, this pages displays errors being logged as they occur. A couple of errors are generally not
cause for unit rejection. If there are a substantial, growing number of errors logged, it indicates an Ethernet
communication issue. Use the FMS knob to check all three Ethernet ports. Generally you should see a
continually increasing number in the RCV GOOD FRAMES and XMT GOOD FRAMES to show Ethernet
communications are ok. This page is protected and cannot be changed.
If the number of errors are continually increasing, check Ethernet wiring between GDU's and GIA's for any
disconnects. If none are found, troubleshoot which LRU (PFD, MFD, GIA 1, GIA2, or GDL) is causing the
problem.
