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 FGSD/FGSW 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 FGSD/FGSW 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.

Flexible Extension Solution
The two mini-GBIC slots built in the FGSD/FGSW 802.3at PoE+ Switch series
are compatible with the 1000BASE-SX/LX SFP (Small Form-factor Pluggable)
fiber transceiver, uplinked to the backbone switch and monitoring center in long
distance. The distance can be extended from 550 meters (multi-mode fiber) to
10/20/40/80/120 kilometers (single-mode fiber or WDM fiber). They are well suited
for applications within the enterprise data centers and distributions.
