25-8 Fabric OS Message Reference
Publication Number: 53-1000242-01
FW-1041
25
Probable
Cause
Indicates that the receive power value of the SFP has changed from a value outside of the acceptable
range to a value within the acceptable range. The receive performance area measures the amount of
incoming laser to help you determine if the SFP is in good working condition or not. If the counter often
exceeds the threshold, the SFP is deteriorating.
Recommended
Action
No action is required. Respond to this message as is appropriate to the particular policy of the end-user
installation.
Severity INFO
FW-1041
Message
Probable
Cause
Indicates that the transmit power value of the SFP has changed. The transmit performance area
measures the amount of outgoing laser to help you determine if the SFP is in good working condition or
not. If the counter often exceeds the threshold, the SFP is deteriorating.
Recommended
Action
Transmitting laser fluctuations usually indicate a deteriorating SFP. If this message occurs repeatedly,
replace the SFP.
Severity INFO
FW-1042
Message
Probable
Cause
Indicates that the transmit power value of the SFP has fallen below the low boundary. The transmit
performance area measures the amount of outgoing laser to help you determine if the SFP is in good
working condition or not. If the counter often exceeds the threshold, the SFP is deteriorating.
Recommended
Action
Verify that your optical components are clean and function properly. Replace deteriorating cables or
SFPs. Check for damage from heat or age.
