Dell PowerEdge FX2 and FX2s Enclosure Owner's Manual

Troubleshooting I/O modules

1. Check that the pass-through module or switch ports are cabled correctly.
2. Ensure that the network daughter cards/LOM cards on the sleds are mapped to the I/O module.
3. Verify that the switch or pass-through module is fully booted, and verify the firmware revision and IP address of the switch or pass-through module.
4. Verify that the switch or pass-through module has a valid IP address for the subnet. Verify by using the ICMP ping command.
5. Check the network connector indicators on the network switch module:
   • If the link indicator displays an error condition, check all cable connections.
   • Try another connector on the external switch or hub.
   • If the activity indicator does not light, replace the network switch module.
6. Using the switch management interface, verify the switch port properties. If the switch is configured correctly, back up the switch configuration and replace the switch. See the switch module documentation for details.
7. Ensure that the appropriate Network Daughter Card(s) (NDC) are installed in the sled(s). If the network link indicator on the sled is green, then the sled has a valid link to the I/O module.
8. Ensure that the appropriate operating system drivers are installed and that the protocol settings are configured to ensure proper communication.
