Question about Dell PowerConnect 2016 (pct2016) Networking Switch
Does anyone know what it means when all the LED's on the front pannel are solid green. User manual has no answer. Was working fine until today computers will have a connection no problem, then the LED's all turn solid green and i have no connection.
Had same problem with my Dell Pwoerconnect 2016, power it on and all LEDs light up but nothing works.
The problem was traced to one or both output capacitors ( 10v 680uf ) on the ( tiny ) power supply.
Capacitor symptoms include bulging or rounded tops instead of flat like new one and the rubber plug in base of capacitor protruding.
Capacitors need to be replaced.
I have successfully replaced with 10v 1000uf and 10v 1200uf, both Rubycon and Sanyo brands.
Power to the switch board is now restored and the switch is able to function just fine.
Give it a go and see if it works for your Powerconnect.

Are all three rows of lights on solid green?? This is either some sort of switch failure or possibly a broadcast storm, network loop condition, or defective NIC card in an attached computer.
With the lights on, try removing all of the data cables...slowly, one at a time. If the lights go off, check to see where the cable goes that you just removed. If all of the lights remain on even with no network cables attached, then the switch has probably failed. Confirm this by unplugging power and plugging back in...with no data cables...if problem returns...the switch will need to be replaced.

The Lights blinking with no cables in it? There is a problem with the power. The power to the mainboard must be 3.3 volts.
I've solved it with new condensators in the powersupply,
