The devices at both ends of the link are powered-up.
●
Both ends of the Gigabit link are set to the same autonegotiation state.
●
The Gigabit link must be enabled or disabled on both sides. If the two sides are different, typically
the side with autonegotiation disabled will have the link LED lit, and the side with autonegotiation
enabled will not be lit. The default configuration for a Gigabit port is autonegotiation enabled. Verify
by entering the following command:

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 the power,
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.
