connectivity. When you connect your network devices, do not exceed
the maximum cabling distance of 100 meters (328 feet). It can take up to
one minute for the attached devices or the LAN to be operational after it
is connected. This is normal behavior.

Power over Ethernet Considerations

The switch is to be connected only to PoE networks without

routing to the outside plant.
If your switch is one of the Power over Ethernet (PoE) models, consider the
following power requirement:
