Product Overview
The FS980M Series switch is a managed Fast Ethernet switch with SFP
slots. This series switch provides a simple solution to replace an edge
switch in small and medium-sized enterprises.
The eco-friendly feature automatically saves power consumption on each
port when the port has not established a link.
