I’m not sure what is it with tech manufacturers these days. They have to make the LED’s brighter and brighter. Below you will see four switches. The bottom two Cisco units have resonable brightness LED’s but Dell EMC went over the top with the S4100 series. They want us to know those fans are working.
Whats funny though is that they are so bright you can hardly see. Plugging in the Ethernet cable and console cable while half blinded was well interesting. Another day in the life.
