The LED functionality of the TC2201 is detailed below:
•Power and Fault (Pwr)—This indicator is a bi-color LED. When green, this indicator shows that power is currently active. Lack of power indication suggests that the unit is turned off, a problem with the power supplied to the unit, or an internal problem with the unit. When this indicator is amber, this indicator shows that the TC2201 detects a fault condition. Faults can occur as a result of Power On Self Test (POST) failure or operational failures. It is normal for this indicator to flash on when the unit is powered up or reset. If the fault indicator stays lit, contact your product support representative.
•iSCSI (Lnk/Act)—When lit green, the upper indicator signifies a good iSCSI link on the port. When lit green, the lower indicator signifies iSCSI port activity. If the Link indicator fails to light at all, or if the Activity indicator stays continually lit without corresponding SCSI bus activity, there may be a problem with the iSCSI configuration. Verify the iSCSI configuration.
•SCSI Bus (0, 1)—When lit, these green indicators signify SCSI activity on the bus corresponding to the number of the indicator. Activity should be indicated only occur briefly during power up or configuration, and relatively often when the unit is transferring data. If an Activity indicator stays continually lit without corresponding target device activity, there may be a problem with the SCSI bus configuration. Verify the SCSI bus configuration.
•Ethernet (10/100)—When lit, these green indicators signify Ethernet link status and activity. If either of these indicators fail to flicker, or stay continuously lit, there may be a problem with the network connection or configuration. Verify the network connection and configuration. The port must be connected to a 10/100BaseT Ethernet network to function properly.
