3. Troubleshooting with TICU installation 3-1. Input power problem 1) Phenomenon All LEDs are off status after Power ON. 2) Corrective Action (1) Connect the - terminal of DMM to RTN(Red) marked pin on TICU front panel. (2) Connect the + terminal of DMM to –48V(Blk) marked pin on TICU front panel. (3) And check that the input DC voltage is in the range -36~-60V. (4) If the input DC voltage is not in the range -36~-60V, check the PDU unit status of RAS rack. (5) If the input DC voltage is in the range +36~+60V, please twist the cable from RAS rack. (6) If the input DC voltage is in the range -36~-60V, check that the POWER switch is exactly ON status. (7) If the switch is normal and the input DC voltage is in the range -36~-60V with no operation of all LEDs, contact us. Refer to chapter 5 about the contact information.

Communication Error in WEB GUI 1) Phenomenon There is no response when you are typing 192.168.0.2 in Internet explorer. 2) Corrective Action (1) First of all, check the Ethernet cable status and the LINK led status of TICU. (2) And then check that Device scan process is now processing. Please be cautious that there is no response from TICU during device scan process. (3) The first device scan process will start 5 seconds later after power ON. And then next device scan process will start every 20 minutes. (4) The normal scanning time is illustrated below. It might be different according to the combination of the unique ID of ALDs. The maximum time of Device scan is about 5 minutes. This is only the case of the first scan process. -. No ALD: about 5 seconds -. 2 ALDs: about 45 seconds -. 4 ALDs: about 1minute 25 seconds -. 6 ALDs: about 2minute 5 seconds (5) The cable and LED status are abnormal, please replace the cable. (6) If the status is normal, check the network configuration of your laptop PC. (7) If you click the properties of Local Area Connection, figure 4-1-2 will be showed. (8) And then select the item Internet Protocol (TCP/IP). (9) And then click the Properties button. (10) Verify the IP address setting is same as figure 4-1-3. (11) If not, please set the IP address setting like as figure 4-1-3.
