SFP power messages in log

I'm getting these troubling messages in the log of a EX4200-24F switch

 

chas[663]:  link 1 SFP receive power low  warning set
chas[663]:  link 1 SFP receive power low  warning cleared

 

every hour or so.  What does this mean, and how can I even find out with SFP it is?

Re: SFP power messages in log

"receive power low" means that the level of light being received is getting close to the minimum for operation. You may need a different sort of SFP if it is a long distance or you may have bad quality cables/connectors - or just too long a cable.

Re: SFP power messages in log

Thank you, that is what I had assumed as well. 

Which SFP is it though?  Link 1 refers to the first SFP or what?
