To troubleshoot a loss of Ethernet connectivity, perform the following steps:
Troubleshooting loss of Ethernet connectivity
1 |
Verify that the connector crimps on the Ethernet cable are not loose. |
2 |
Verify that the Ethernet cable is not damaged. |
3 |
If the Ethernet cable connects the module to a network interface card (NIC), verify that the cable is pinned out as a straight-through cable. |
4 |
If the Ethernet cable connects the module to a hub, switch, or router, verify that the cable is pinned out as a crossover cable. |
5 |
Verify that the Ethernet port to which the cable connects the module is set to auto-negotiate speed. |
6 |
Verify VLAN configuration in the network, which may cause loss of module access if the accessing device is on a separate VLAN from the radio. |
7 |
Power cycle the module. |
8 |
In this latter case and if the module has encountered no customer-inflicted damage, then request an RMA for the module. |
