I acquired a Linksys SD205 5-port 10/100 network switch that's missing its AC/DC adapter (power supply). The label on the switch case by the power input says "DC 12V/500mA." I dug through my spare parts and came up with a power supply rated at 9 volts and 500mA. It had been used for a cordless phone base station. I plugged it in and my volt meter indicated 14.23 volts. I checked some other power supplies of different ratings and they were all outputting above their rated levels, so this doesn't seem to be unusual. I'd feel more comfortable using a power supply that was putting out less voltage, but I wonder if the Linksys power supply also outputs about 14 volts.
Does anyone out there have a Linksys SD205 5-port 10/100 network switch power supply that they could check the voltage at the output and tell me what they discover? Also, what are the consequences of slightly excessive voltage for a network switch such as this? Can it harm the computers on the network or will it just fry itself?
I'd appreciate any assistance provided.
