For Temperature, Tx Power, Rx Power, and Tx Bias Current, values are displayed along with one of the following
status values: Low-Alarm, Low-Warn, Normal, High-Warn or High-Alarm. The thresholds that determine these
status values are set by the manufacturer of the XFPs. Table 5.2 describes each of these status values.
NOTE: This function takes advantage of information stored and supplied by the XFP device. This information is
an optional feature of the Multi-Source Agreement standard defining the XFP interface. Not all component
suppliers have implemented this feature set. In such cases where the XFP device does not supply the information,
a “Not Available” message will be displayed for the specific port that the device is installed
