Standard, VLAN and Extend Operation Modes Offered
The GSW 802.3at PoE+ Switch series provides Standard, VLAN and Extend
operation modes. The GSW 802.3at PoE+ Switch series operates as a normal IEEE
802.at/af 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 GSW 802.3at PoE+ Switch series operates on
a per-port basis at 10Mbps duplex operation but can support 30-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 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.
