If the LED is on, the link between the port and the next piece of network equipment is OK. If the LED is off, nothing is connected, or the connected device is switched off, or there is a problem with the connection (refer to the “Problem Solving” section). If flashing, the port is partitioned, possibly due to a network loop.
