The LED functionality of the TC2201E 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 TC2201E
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
