switch. before you install and use this product, please read this manual carefully for fully exploiting the functions of this product. 1.1 product overshow this is a high performance the layer 2 managed gigabit switch, which provides 48 10/100/1000mbps auto-negotiation rj45 port, and four gigabit sfp ports. the switch can be used to link higher bandwidth upstream devices. in order to ensure the effective allocation of bandwidth to each port, store-and-forward technology is used by the switch, also combined with dynamic memory allocation. support vlan port based on acl, easy network monitoring, traffic regulation, priority remark and traffic control. the switch support traditional stp/rstp/mstp layer 2 link protection technology, which could greatly improve the ability of fault
