31.5.6 Module Does Not Establish Ethernet Connectivity
To troubleshoot a loss of Ethernet connectivity, perform the following steps.
Procedure 53: 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. Power cycle the module.
7. RESULT: Approximately 25 seconds after the power cycle, the green LED
labeled LNK should light to indicate that the link has been established. If the
orange LED labeled SYN is lit instead, then the module is in Alignment mode
because the module failed to establish the link.
8. In this latter case, and if the module has encountered no customer-inflicted
damage, then request an RMA for the module.
