Cost-Optimized Managed Switch for Small and Medium BusinessesPLANET GS-421 -16T2S is an ideal Gigabit Switch which provides cost-effective advantage to local area network and is widely accepted in the SMB office network. It offers intelligent Layer 2 data packet switching and management functionsfriendly web user interface and stable operation. Besides the hot IPv6 / IPv4 management and abundant L2 / L4 switching functions the GS-421 -16T2S comes with fanless feature and green technology to provide a quiet energy-saving high-speed and reliable office network environment. The GS-421 -16T2S is equipped with 16 1 /1 /1 BASE-T Gigabit Ethernet ports and 2 additional 1 /1 BASE-X SFP interfaces with inner power system. It offers a rack-mountable affordable safe and reliable Gigabit network switch solution for SMBs deploying networks or requiring enhanced data security and network traffic management.Robust Layer 2 FeaturesThe GS-421 -16T2S can be programmed for advanced switch management functions such as dynamic port link aggregation 8 2.1Q VLAN and Q-in-Q VLAN Multiple Spanning Tree protocol (MSTP) Loop and BPDU Guard IGMP Snooping and MLD Snooping. Via the link aggregation the GS-421 -16T2S allows the operation of a high-speed trunk to combine with multiple ports such as a 16Gbps fat pipe and supports fail-over as well. Also the Link Layer Discovery Protocol (LLDP) is the Layer 2 protocol included to help discover basic information about neighboring devices on the local broadcast domain.
