The last submitted configuration changes will also take effect after the TC2201E powers on again. Select the Submit button to finalize your choice. Figure 59 Reboot Page 86 Quantum TC2201E User's Guide Chapter 4 4Troubleshooting Various problems can arise when configuring and using the TC2201E. This section is provided to help guide the user through some of the basic methods of identifying faults in the setup and configuration of the unit. Most problems are found in the initial installation. In general, it is wise to check all connections and review the configuration before proceeding with further trouble analysis. Simplify the installation if possible, reducing it to the most basic configuration then adding elements one at a time and verifying the operation at each step. Indicators 4 The TC2201E is equipped with rear panel LED indicators for monitoring overall unit status. Quantum TC2201E User's Guide 87 Chapter 4 Troubleshooting Indicators Figure 60 TC2201E LEDs Ethernet Activity iSCSI Link Status Power/Fault SCSI Activity for Bus 0 iSCSI Activity SCSI Activity for Bus 1 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. 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. 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 Quantum TC2201E User's Guide · · · 88 Chapter 4 Troubleshooting Basic Verification connection or configuration. Verify the network connection and configuration. [. . . ] The SCSI address of a device dictates the device's priority when arbitrating for the SCSI bus. SCSI address "7" has the highest priority. The next highest priority address is "6" followed by 5, 4, 3, 2, 1, 0, 15, 14, 13, 12, 11, 10, 9, 8, with "8" being the lowest priority address. The narrow SCSI adapter is factory set to address 7.
