Standard, VLAN and Extend Operation Modes Offered
The GSD/GSW 802.3at PoE+ Switch series provides Standard, VLAN and Extend
operation modes. The GSD/GSW 802.3at PoE+ Switch series operates as a normal
IEEE 802.af/at PoE Switch in the Standard operation mode. The VLAN operation
mode features the port-based VLAN function that can help to prevent the IP
camera's multicast or broadcast storm from influencing each other.

In the Extend operation mode, the GSD/GSW 802.3at PoE+ Switch series operates
on a per-port basis at 10Mbps duplex operation but can support 20-watt PoE
power output over a distance of up to 250 meters overcoming the 100m limit on
Ethernet UTP cable. With this brand-new feature, the GSD/GSW Series provides
an additional solution for 802.3af/at PoE distance extension, thus saving the cost
of Ethernet cable installation. Its VLAN isolation function isolates ports so as to
prevent broadcast storm and defend DHCP spoofing in the Extend operation mode.
