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."
