ZyXEL GS-1548 is a 48-port L2 Gigabit switch with advanced Web-based management support and it's specially designed for SMB/Enterprise networks where extra bandwidth and advanced QoS or security features are required. To cope with the diverse requirements of SMB/Enterprise businesses, the ZyXEL GS-1548 Web-managed switch comes with 40 Gigabit copper ports plus 4 dual-personality (RJ-45/SFP) Gigabit ports to provide 96 Gbps of non-blocking connectivity for SB/SMB networks. With the flexible multi-function design, GS-1548 fits any network with very little effort.

 

 

	ZyXEL GS-1548 is a 48-port L2 Gigabit switch with advanced Web-based management support and it's specially designed for SMB/Enterprise networks where extra bandwidth and advanced QoS or security features are required
	To cope with the diverse requirements of SMB/Enterprise businesses, the ZyXEL GS-1548 Web-managed switch comes with 40 Gigabit copper ports plus 4 dual-personality (RJ-45/SFP) Gigabit ports to provide 96 Gbps of non-blocking connectivity for SB/SMB networks
	While many legacy Web-based Smart Switches improve manageability, configuration complexity is still an issue; for most SB/Enterprise, inadequate IT expertise and complicated configuration are the major concerns to overcome
	Security is becoming increasingly important in SMB/Enterprise networks. Equipped with Auto DoS Attack Prevention, the GS-1548 is capable of protection against ubiquitous DoS attacks. A few mouse clicks are all it takes to initiate the protection
	The GS-1548 supports 802.1Q VLAN for traffic isolation, as well as Static MAC forwarding and dynamic ARP to establish a strictly protected network
	"Auto VoIP" offers IP telephony without configuration headaches; features such as four priority queues and the WRR (Weighted Round Robin) scheduling algorithm are usually deployed on enterprise networks, allowing users to optimize network bandwidth usage and implement QoS

	96 Gbps Non-blocking Switching Fabric for the fastest speeds
	Flexible 4 GbE Uplink Interfaces provide maximum speed between switches
