FreeWave Technologies Ethernet Addendum
900 MHz
V204
Installation:
To install the modem, proceed as described in the Main Manual, with the following
exceptions:
•Connect the modem to the LAN with a CAT5 RJ45 Ethernet cable.
•Use the "Normal/Crossover" switch to select the polarity of the Ethernet
connection. If connecting to a switch, router or hub, select "Normal". If
connecting to a NIC or a modem, select "Crossover". However, if you are
using a crossover cable, then use the opposite settings of the switch.
•If required, use the top row of LEDs for troubleshooting the Ethernet Interface.
Troubleshooting:
To troubleshoot the modem, proceed as described in the Main Manual. Additionally,
use the top row of LEDs in this Ethernet modem as troubleshooting tools.
•No data is being passed between the LAN’s.
Upon power up, the ethernet interface’s MAC filtering table can become
corrupted, and must be reset, or allowed to timeout. After power up, press
the reset button on the back of the FreeWave ethernet, or allow 4.5 minutes
to pass and the table time to reset.
•The LINK LED is off:
The Modem is not successfully connected to the LAN.
Make sure that the Modem is powered On.
Make sure that the Ethernet device connected to the Modem is On.
Make sure the Modem and the Ethernet device are connected with a good
Ethernet cable.
Try flipping the "Normal/Crossover" switch to the opposite position.
Check that the Ethernet device attached to the Modem is either set for auto-
detect, or for 10BaseT.
•The TX LED stays on:
Data isn't going from this modem's LAN to the other modem's LAN.
Make sure the radio link is working (see Main Manual).
Make sure both modems are linked to their respective LANs (the modems'
LINK LEDs are on).
•The RX LED stays on:
Data isn't going between this modem and its LAN.
The Ethernet device to which this modem is connected isn't receiving data.
•The COL LED flashes:
There are collisions on this modem's LAN
This is normal when the modem's connection to the LAN is through a hub (it
simply means that two Ethernet devices tried to send data through the hub at
the same time). The Ethernet network is designed handle such collisions.
This doesn't happen when the modem's connection to the LAN is directly
through a switch, or to a NIC, or to a router.
•The ERR LED flashes:
