7 Ethernet switch ports 0–7 Layer 2 switch ports that provide flexible VLAN configuration.
Note Ethernet switch ports 6 and 7 also support PoE devices. If
a PoE device is not attached, power is not supplied to the
port and the device must be powered on its own.
8 PoE switch ports 6–7 Can be used for PoE devices, that is, devices that can be powered by
the network interface, such as IP phones.
These ports are the only ports that can be used for IP phones or other
PoE devices. However, these ports are not restricted to that use.
They can also be used as Ethernet switch ports, as are the ports
numbered 0 through 5. If a PoE device is not attached, power is not
supplied to the port and the device must be powered on its own.
