A case for handling CFGDATA_OUTRANGE alarm on OSN6800

Publication Date:  2012-07-25 Views:  36 Downloads:  0
Issue Description
Engineer  found  three CFGDATA_OUTRANGE alarms reported on  slot 18 SCC board of OSN6800 
Alarm Information
123804      18    CFGDATA_OUTRANGE                  MJ          start       2010-06-02 11:32:28      None                     0x04   0x0f   0x01   0x00   0x01   
 
 123805      18    CFGDATA_OUTRANGE                  MJ          start       2010-06-02 11:32:28      None                     0x04   0x0f   0x02   0x00   0x01   
 
 123806      18    CFGDATA_OUTRANGE                  MJ          start       2010-06-02 11:32:28      None                     0x04   0x0f   0x04   0x00   0x01   
Handling Process
1. query the logic board and the physical board, engineer confirmed the slot  15 is MR8
2. query the add/drop wavelengths on slot 15 MR8 with navigator.   
for { set i 1 } { $i < 9 } { incr i } {
:cfg-get-mdwave:15,$i;
:cfg-get-cfgmdwave:15,$i;
}
3. Engineer found wrong configuration wavelength in MR8 
 MR8 realize add/Drop of 8 wavelength from lambda 1 (192.1THz) to lambda 8 (192.8THz), Engineer found that there was some wavelength configured in MR8 out 
of this range 
4. Engineer  set the wavelength in T2000 with the value queried. The alarms were disappeared.
Root Cause
OSN6800 SCC's version is  5.51.04.14
According to the product manual, 
The first parameter 0x04 denotes the add/drop wavelengths.
The second parameter 0x0f denotes the faulty board's slot is 15.
Suggestions
The CFGDATA_OUTRANGE  alarm should be handled duiring engineering. the add/drop wavelength should be carefully checked.
