Transmit Performance Area Messages

Probable Cause

The Transmitted Optical Power of the SFP transceiver is outside of the factory set
normal range. The transmit performance area measures the amount of outgoing
laser (in milliamp) to help you determine if the SFP is in good working condition
or not. If the counter often exceeds the threshold then the SFP is deteriorating.

FW-EXCEEDED, 3, sfpRX<element index> (Sfp RX power <element
index>) exceeded boundary, current value: <value> µWatts. (info)
Explains that the receive power value has risen above or fallen below the
acceptable range. Provides the new value.
This error indicates that you must replace the SFP before it deteriorates.
FW-BELOW, 3, sfpRX<element index> (Sfp RX power <element index>)
is below low boundary, current value: <value> µWatts. (info)
Explains that the receive power value has fallen below the low boundary.
Provides the new value.
This error indicates that you must replace the SFP before it deteriorates.
FW-ABOVE, 3, sfpRX<element index> (Sfp RX power <element index>)
is above high boundary, current value: <value> µWatts. (info)
Explains that the receive power value has risen above the high boundary.
Provides the new value.
This error indicates that you must replace the SFP before it deteriorates.
FW-INBETWEEN, 3, sfpRX<element index> (Sfp RX power <element
index>) is between high and low boundaries, current value: <value>
µWatts. (info)
Explains that the receive power value has changed from a value outside of
the acceptable range to a value within the acceptable range. Provides the
new value.
