FW-1041
Probable
Indicates that the receive power value of the SFP has changed from a value outside of the acceptable
Cause
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 No action is required. Respond to this message as is appropriate to the particular policy of the end-user

<Label>, is below low boundary(High=<High value>, Low=<Low value>).
Current value is <Value> <Unit>.
Probable Indicates that the transmit power value of the SFP has fallen below the low boundary. The transmit
Cause 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
Verify that your optical components are clean and function properly. Replace deteriorating cables or
