This section discusses basic methods of identifying problems in the
setup and configuration of the Interface Controller.
Most problems occur during the initial installation of the Interface
Controller. Before proceeding with advanced troubleshooting
techniques, verify all connections and review the configuration.
The following topics are discussed in this section:

LED Indicators
0
The LED indicators on the Interface Controller are useful for
diagnosing various problems:
• 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
Fibre Channel port
LEDs
indicate Fibre Channel activity
(ACT) and link (LNK) 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 a Fibre Channel link.
Verify the Fibre Channel port 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.
Caution:
Confirm there is no activity, such as a backup in
progress, before initiating a reboot as the Interface
Controller activities will be disrupted.
