Why Sys-Admins Are Disabling The Lights on WiFi Access Points (networkworld.com)

More than a dozen IT professionals said they've disabled the LEDs on wireless access points, according to a Network World article shared by Slashdot reader alphadogg: Some users don't want a beacon shining in their eyes as they try to get to sleep and others worry about the health effects of a blue light glowing all night. Some even resort to unplugging the gear when they're not using it.... "It seems when you are sick and laying in a hospital bed and have trouble sleeping, the single LED shining in your eyes is an issue," [says the wireless network staff specialist for Penn State College of Medicine]. "I get it and understand it..."

Network pros say they have begun asking vendors such as Cisco if they can provide an easier way to dim, rather than turn off the lights on the access points entirely, via wireless controllers. And some would like to see more granular control, such that the power light could be left on to comfort end users that the device is working, but blinking lights could be turned off or dimmed to avoid bothering them.

End users have tried "all sorts of makeshift fixes -- from Post-it notes to bandages to condom wrappers," but one network architect complains that when they disable the LEDs altogether, "I invariably get a ticket (or more) that the access point is offline and wireless is broken because there are no lights on..." On the plus side, when they then re-enable the LED lghts, "magically the wireless performance and coverage is perfect!"

E-paper is plenty fast to show plugged-in status or activity. Activity LEDs don't blink based on data anyway.

      Even cheap electronic paper can be updated once per second with fairly low power requirements. For activity, the lights have basically been useless for decades: unless you're the only one on the network and are sending pings one per second, they're basically always on. It would be far more use to have a few more pixels and display a logarithmic scale bar of total throughput. For power on, something that alternated between - and | once per second would let you know that there was power flowing, without needing a static light.

      It's also worth noting that electronic paper does fade over time, just far more slowly than a conventional LCD. If you requirements are only that it holds its image for 10 seconds, then you could manufacture the paper to far lower tolerances and end up with something that would be completely white (well, uniform pale grey) well under a minute after power off.

It would be far more use to have a few more pixels and display a logarithmic scale bar of total throughput. For power on, something that alternated between - and | once per second would let you know that there was power flowing, without needing a static light.

I don't know what their actual blink rate is but I can say for sure it's greater than 10Hz on a highly active port.
