If the temperature of the optical module is too high, the indicator of the corresponding port will be set to red. In this guide, we will cover everything from what causes heat, to monitoring your SFP module temperatures in real time, techniques for managing heat, and preventative maintenance. Is this normal behaviour of router or smth is going wrong? BR, Dmitry Add cooling fan to CRS-326-24P-2S+ ? Impossible to get more than 5. Excess heat can push the laser outside its optimal wavelength and reduce optical power.
