CSS610-8G-2S+IN SFP+ Overheating Risk?

Tue Jan 26, 2021 1:38 pm

I'm still holding out hope that the CSS610-8G-2S+IN will be a viable product for me, despite the dumpster fire that is SwOS Lite, but I have another concern. In my experience, SFP+ Transceivers tend to run really hot. Given that the CSS610-8G-2S+IN is passively cooled, are they going to turn into little hot plates with two SFP+ port being fully utilized? Any anecdotes will be appreciated as some of my use case locations will not have any active cooling.

Thank you,

I run two 10Gb MMf SR ports admittedly not at a constant high load and temps are fine on the optics 36-40c if going by what's reported in webgui.

Edit: 10Gbase-t SFP+ will almost certainly be a bit hotter but I would imagine fine.

My data from RB260GS, CSS610-8G-2S+IN, CSS326-24G-2S+RM, CRS305-1G-4S+IN and CRS326-24G-2S+RM
Room temperature: 21-24°C
  • SFP: 6x Mikrotik S-31DLC20D >> High load >>Temperature: 60-65°C
  • SFP+: 4x OEM (Cisco Compatible) 100-35SM 10G >> Low load >> Temperature: 29-36°C
  • SFP+: 4x Mikrotik S+RJ10 (1G/2,5G/5G/10G) >> Medium load (at 10G) >> Temperature: 75-92°C
S+RJ10 general guidance
