FAQ-Do the Hardware or Software Settings of the OSN 6800 Need to Be Changed When the Input Voltage of the OSN 6800 Is Changed from –48 V to –60 V

Publication Date:  2012-07-25 Views:  48 Downloads:  0
Issue Description
The standard working voltage of the OptiX OSN 6800 is ?48 V or ?60 V DC, and the normal working voltage ranges from ?38.4 V to ?57.6 V (for the ?48 V standard) or from ?48 V to ?72 V (for the ?60 V standard). Therefore, overlap occurs in the the two voltage ranges (?48 V to ?57.6 V). In addition, the overvoltage and undervoltage alarm thresholds differ when the ?48 V or ?60 V is supplied. Do the hardware or software settings of the OSN 6800 need to be changed after the input voltage is changed from ?48 V to ?60 V? 
Alarm Information
Null
Handling Process
When the OSN 6800 uses ?48 V or ?60 V DC input, its hardware settings need not be changed. The standard input voltage of the PIU board, however, needs to be changed on the T2000. 
Root Cause
Null
Suggestions
 For ?48 V or ?60 V DC input, the settings vary with different types of WDM equipment.
1. For the BWS 1600G, you need to change the settings of the fourth DIP switch of the PMU in the power distribution box. If the DIP switch is OFF (down), the PMU monitors the input power of the 1600G equipment powered by the ?48 V power source; if the DIP switch is ON (up), the PMU monitors the input power of the 1600G equipment powered by the ?60 V power source. By default the PMU monitors the input power of the 1600G equipment powered by the ?48 V power source.
2. For the WDM 6100, you need to change the software settings, that is, set the input voltage of the PMU on the T2000.
3. For the OSN 6800, you need to also change the software settings, that is, set the input voltage of the PIU on the T2000.
