ms430580mMesrLine\

This article gives the transmit power value of the SFP plugged into Line 1 and Line 2,

read from the Digital Diagnostic Monitoring (Unit = dBm). The actual Transmit Power

in dBm or mW can be obtained by applying the following formula to the returned

value:

Tx_Pwr(mW) = AV/10000

Tx_Pwr(dBm) = 10xlog(AV/10000)

Parameter Meaning Format

AV Article Value Unsigned word (16 bits)

For example:

A listing of the ms430580mMesrportaTxPower outputs the following:

***** SNMP QUERY STARTED *****

1: ms430580mMesrportaTxPower (integer) 30

***** SNMP QUERY FINISHED *****

The value returned from the SFP in Line 1 is: 30.

So applying the formula: Tx_Pwr(mW) = 30/10000

Gives an actual value of: 0.003mW

And applying the formula: Tx_Pwr(dBm) = 10xlog(30/10000)

Gives an actual value of: -25.23dBm
