Troubleshooting The I/O Module - Dell PowerEdge VRTX Owner's Manual

Troubleshooting The I/O Module

NOTE: To eliminate the possibility of a hardware problem with the module or its attaching devices, first ensure that
the module is properly initialized and configured.
1. Check that the pass-through module or switch ports are cabled correctly.
2. Ensure that the network daughter cards/LOM cards on the server modules are mapped to the I/O module.
3. Verify that the switch or pass-through module is fully booted, and verify the switch's firmware revision and IP
address.
4. Verify that the switch module has a valid IP address for the subnet. Verify 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 server module(s). If the network
link indicator on the server module is green, then the server module 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.
