temperature, optical input power, etc. provided by the DDM. The DDM or Digital

Diagnostic Monitoring in each SFP provides real-time monitoring of voltage and

temperature readings of each optical component, together with thresholds and alarms.

A description of all the available measurements can be found in Appendixes.

The following describes the method of interpretation of the different types of

measurements:

Temperature

The object:

• ms430580mMesrportaTemperature

Location:..\microsens\modulems430580m\ms430580mmeasures\

ms430580mMesrClient\

The object:

• ms430580mMesrportbTemperature

Location:..\microsens\modulems430580m\ms430580mmeasures\

ms430580mMesrLine\

Give the temperature value of the SFP plugged into Line 1 and Line 2, read from the

Digital Diagnostic Monitoring (Unit = °C) . The following formula must be applied to

the returned value in order to obtain the actual temperature:

T (°C) = MSB + LSB/256

Parameter Meaning Format

MSB Most Significant Byte Signed Byte

LSB Least Significant Byte Unsigned Byte

For example:

A listing of ms430580mMesrportaTemperature outputs the following:

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

1: ms430580mMesrportaTemperature (integer) 11066

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

The value returned from the SFP in Line 1 is: 11066. This is a decimal value,

the Hexadecimal equivalent is: 2B3A

2B (hex) = 43 (dec) and 3A (hex) = 58 (dec)

So applying the formula: T = 43 + 58/256

Gives an actual temperature of: + 43.23°C

Voltage

The object:

• ms430580mMesrportaVolt

Location:..\microsens\modulems430580m\ms430580mmeasures\

ms430580mMesrClient\

The object:

• ms430580mMesrportbVolt
