["Cost-effective 16 port managed Gigabit Layer-2 switch + 4x SFP MiniGbic slots without fan for desktop and 19\" rack installation The new ALLNET ALL-SG8420M switch represents an optimal basis for small and medium-sized workgroups with high network and data volumes and enables fast data transfer in the network. With a total of 16 backwards compatible Gigabit ports + 4x MiniGBIC slots, the connected computers and servers are reliable and powerful Thanks to the fanless design, the ALL-SG8420M is also ideal for use in an office environment, as no annoying noise is generated. The switch can be managed smartly and therefore supports all necessary standards such as QoS, VLAN, storm control or IGMP snooping.
