LED indicators
The LED indicators on the e2400-160 FC, e2400-FC 2G, and e2400–FC 4G 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.
