Basic Troubleshooting
LED Indicators
The LED indicators on the router are useful for diagnosing various problems:
■The Fibre Channel port LEDs indicates Fibre Channel activity and link status. If one of these indicators does not light or stays continually lit without any corresponding SCSI bus activity, it may indicate a problem with the Fibre Channel link. Verify the Fibre Channel configuration.
■The SCSI bus LEDs indicates SCSI activity. These indicators are lit during power up, configuration, and when the unit is transferring data. If the SCSI indicator stays continually lit without any corresponding Fibre Channel LED activity, it may indicate a problem with the SCSI bus configuration. Verify the SCSI bus configuration.
■The Ethernet LEDs indicates activity and link status. If one of these indicators does not light or stays continuously lit, it may indicate a problem with the network connection. Verify the network connection. The port must be connected to a 10/100BaseT Ethernet network to function properly.
Additional information on the specific LEDs is available in Chapter 1, "External Features Overview."
