LED Indicators
The LED indicators on the router are useful for diagnosing various problems:
■
The Power LED indicates when power is applied to the router.
If the power LED is not lit, verify the power supply source or check for an
internal problem with the power module.
■
The Fault LED indicates that the router detects a fault condition on the power
module.
If the fault indicator stays lit, contact Systems Support.
■
The Fibre Channel LEDs indicate 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 indicate 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 indicate 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.
■
The System Status LED indicates system power is on.
An amber light indicates a system fault condition. System faults can occur as
a result of a Power On Self Test (POST) failure or operational failures. It is
normal for this indicator to flash when the unit is powered up or reset. When
the LED continuously alternates between green and amber, this indicates the
router is in Beaconing Mode.
Additional information and illustrations of the specific LEDs is available in
