Switch does not power up:
All products manufactured by Extreme Networks use digital power supplies with surge protection. In
the event of a power surge, the protection circuits shut down the power supply. To reset, unplug the
switch for 1 minute, plug it back in, and attempt to power up the switch.
If this does not work, try using a different power source (different power strip/outlet) and power cord.
