Power Over Ethernet
LAN Switch
LS820GR is a low cost high performance Managed Gigabit Ethernet switch. This switch supports remote management by Http interfaces. LS820GR supports lots of L2 switch management functions, e.g. 802.1Q VLAN, Rate Control, Port Configuration, Port Mirroring, IGMP Snooping, Loop Protection, QoS functions, ... etc. Auto-MDIX function is supported for every TX port of the switch for easy cable connection. EEE power saving is supported for Green Switch request.
