We use inexpensive unmanaged switches (Netgear, Dell PowerConnect) on our company's manufacturing floor. The electricity gets shut off every night, and the next day we get connection problems. Sometimes we have to unplug the Source cat 5 cable and plug it back in to fix the problem. I've had experience in the past where I've had to turn a switch on without anything else plugged into it and *then* plug in all of the cat 5 cables into it after it was already on. I'm trying to fix this problem without having to run a constant electrical source that doesn't get shut off at night to all of the switches if possible. Are there inexpensive switches that respond better to being shut off and turned back on? Is there a feature of certain switches that I should be looking for that will resolve this problem?
