The 8 gigabit PoE ports provide a fast gigabit connection to the server or network backbone. The effective connectivity of the 10/100/1000Mbps ports enables benefits on any type of network due to superior performance by encouraging network expansion. This high-performance switch features non-blocking switching capacity, and switching speeds of up to 20Gbps. All PoE RJ45 ports can automatically adjust the maximum connection speed for normal operation, Auto Uplink technology can ensure proper network connection.

These devices enable simplified wireless access point (AP) installations and video surveillance installations. Devices away from the power outlet are powered directly from the switch. PoE eliminates the need to connect these devices to the power outlet. So it makes installation more flexible by preferring it for all those devices to be connected where the AC outlet is far away. It is an ideal choice for those who wish to set up a small commercial network or a home network using IP-based surveillance cameras.

If the VLAN dip-switch on the 3000/451 is ON then the 3000/451 switch does not do packet routing between PoE ports so as to speed up routing to and from the Uplink ports; in this case an NVR needs to be connected only to the Uplink ports in order to see the cameras connected on the PoE ports.
