5.1.8.11 Serial/Ethernet I/O Page

The Serial/Ethernet I/O Page displays Ethernet communication statistics (Figure 5-16). If
Ethernet communication symptoms are suspected, this page logs errors as they occur and
displays them. A few 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. There should generally be a continually increasing
number in the RCV GOOD FRAMES and XMT GOOD FRAMES to show Ethernet
communications are working. This data on this page is protected and cannot be changed.
If the number of errors are continually increasing, check the Ethernet wiring between GDU's and
GIA's for any disconnects. If none are found, troubleshoot which LRU or GDL is causing the
problem (PFD, MFD, GIA 1, or GIA2).
