Hi,
I need a switch that when initially powered on delays its output for 30 minutes.
I have a situation where my Ubiquiti UDM SE switch doesn't like to be powered off for a short time. It never successfully reboots unless it is turned off for at least 20 minutes, but 30 is safe. I have it plugged into a UPS, but if the power comes back on shortly after UPS runs out of power, then the switch hangs with "taking a little longer" notice forever. The thought is to plug it into the switch described. I could build something, but off the shelf would be better. Ideas?
I am planning to exchange the switch, but some logistical problems necessitate an alternate short-term solution.
