Method used to query the gain of an OA board

4

In the NE Explorer of the U2000, choose Configuration > WDM Interface. Then query or set the value of the Nominal Gain parameter.

Querying the nominal gain and actual gain of an E3OAU board through the CLI
1. Query/Set the current nominal gain of the board by running the :cfg-get/set-stdgain:bid,4,1 command. 2. Query the current actual gain of the board by running the :cfg-get-gain:bid,4,1 command. 3. The actual gain is the optical power of the OUT port minus the optical power of the IN port.

Alarm threshold modification for E4 and E5 series OA boards
1. Run the following command to query the alarm thresholds. Pay attention that the board slot ID must be replaced with the actual slot ID and the slot ID must be in decimal format. :cfg-get-almth:5,1,1,sumiop PER-ALM-TH BID PORT PATH TH-TYPE TH-HIGH TH-LOW 5 1 1 sumiop 10 -320 Total records :1 2. Run the following nptp command to query the alarm thresholds on the board side. Pay attention that the board slot ID must be replaced with the actual slot ID and the slot ID must be in hexadecimal format. In the command outputs, TH-HIGH indicates the upper threshold in decimal format and TH-LOW indicates the lower threshold in hexadecimal format. After the lower threshold in hexadecimal format is converted into a value in decimal format, the lower threshold must correspond to the threshold queried in step 1. :nptp:5,13,31,1,0,1,0,94 ncmd 0: 05 13 31 00 00 01 00 01 00 94 00 00 00 0a ff ff fe c0 In the command outputs, 00 00 00 0a is the upper threshold and ff ff fe c0 is the lower threshold. 3. Run the following nptp command to query the alarm thresholds on the board side. Pay attention that the board slot ID must be replaced with the actual slot ID and the slot ID must be in hexadecimal format. The upper threshold is 0x12 in hexadecimal format, which is 18 in decimal format. That is, the upper threshold is 1.8 dB. :nptp:$bid,13,30,1,0,1,0,94,0,0,0,12,ff,ff,fe,c0 ncmd 0: 05 13 30 00 00 In the command outputs, 00 00 00 12 is the upper threshold and ff ff fe c0 is the lower threshold. 4. Query the alarm threshold again to check whether the alarm threshold is successfully modified. :cfg-get-almth:5,1,1,sumiop PER-ALM-TH BID PORT PATH TH-TYPE TH-HIGH TH-LOW 5 1 1 sumiop 18 -320 Total records :1 5. Replace the nptp command in step 2 with the sptp command and then deliver the command again without changing other parameters. In this manner, the command is saved to the NE software and will not be lost during a board reset. :sptp:5,13,30,1,0,1,0,94,0,0,0,12,ff,ff,fe,c0

Calculation of the total input optical power of an OA board
The total input optical power of an OA board can be calculated using the following formula: Total input optical power = Single-wavelength nominal input optical power + 10lgN (N: number of in-service wavelengths).

Method used to query board manufacturer information
You can view the board manufacturer information in the board manufacturer information report on the NMS.

Method used to query board power consumption on the U2000
On the U2000, choose Configuration > NE Batch Configuration > Power Management from the main menu. Then, click the Board Power tab to query the nominal power consumption and the current power consumption of the board. The nominal power consumption of a board is a fixed value and has been calibrated in board software. The current power consumption of a board is the actual power consumed during board operation. The value is calculated based on the actual voltage and current.
