FC interface controller problems
Most problems occur during the initial installation of the interface controller.
Before proceeding with advanced troubleshooting techniques, verify all
connections and review the configuration.
LED indicators
The LED indicators on the e2400-160 FC and e2400-FC 2GB interface controllers
are useful for diagnosing various problems:
■
SCSI bus LEDs (e2400-160 FC interface controller only) — indicate SCSI
activity. These indicators are lit during power on, configuration, and when the
unit is transferring data. If the SCSI indicator stays continually lit without any
corresponding FC LED activity, it may indicate a problem with the SCSI bus
configuration. Verify the SCSI bus configuration.
■
FC port LEDs — indicate FC activity (ACT) and link (LNK) status. If the
link LED does not light it may indicate a problem with a FC link. Verify the
FC port configuration and cabling.
■
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 or cabling. Verify the network connection. The port must
be connected to a 10/100BaseT Ethernet network to function properly.
See
for LED locations and functions on the e2400-160 FC interface
controller.
