LAN Interface
See the “System Configuration” section of the FieldFox Analyzer User’s Guide
(Part Number N9927-90001) for details on reviewing and configuring LAN
settings.
The LAN interface supports Auto MDIX. When a LAN cable is connected to the
FieldFox, if the other end of the cable supports Auto MDIX, there is no need for
a cross-over cable.
There are two LEDs on the LAN connector. When there is successful
communication over a LAN cable, both LEDs are active. If both LEDs are not
active, consider using a cross-over cable.
LAN LEDs (N995xA and N996xA only)
When FieldFox is connected to the LAN, the flashing LAN LEDs have the
following definitions:
Green: Flashing indicates packets are being transferred.
Yellow:
— Flash, pause = 10 Mbit link speed
— Flash, flash, pause = 100 Mbit link speed
— Flash, flash, flash, pause = 1 GBit link speed
