ZyXEL ES-1552 comes with 48 Fast Ethernet copper ports plus four Gigabit uplinks (two 1000Base-T ports and two SFP slots) that fire up the non-blocking connection power to 17.6Gbps on SMB/SB networks and its multi-function design fits into copper or fiber networks easily. By utilizing 4G uplinks and port aggregation, bandwidth on critical paths can be expanded flexibly by merging multiple traffic pipelines into a logical one to dramatically improve network stability.

 

 

	While many legacy Web Smart switches improve manageability, complexity is still a challenge. For most SMBs, inadequate IT expertise and complicated configurations are the major obstacles to overcome before getting connected. Powered by the newest hardware platform with smart ACL technology
	The ZyXEL ES-1552 comes with a streamlined and intuitive Web-GUI for features demanded by SMB; such as 802.1Q VLAN, 802.1p traffic priority and static port aggregation. Requiring no awkward configurations or bulky user guide, the ES-1552 provides valuable features and convenience for SMBs
	ZyXEL is highly aware that network security is a top priority for SMBs and has therefore enabled the ES1552 to effectively combat DoS attacks. Equipped with Auto DoS Attack Prevention, the ES-1552 is capable of fighting against ubiquitous DoS attacks
	ES-1552 supports 802.1Q VLAN for traffic isolation, as well as static MAC forwarding and dynamic ARP to establish a strictly protected network
	It usually requires IT expertise to optimize a network for VoIP applications. With the emergence of the "Auto VoIP", however, the ES-1552 can identify VoIP packet patterns and grant the highest priority to establish a VoIP-friendly communication automatically
	Auto VoIP offers IP telephony without configuration headaches. Features like four priority queues and a WFQ scheduling algorithm allows users to optimize network bandwidth usage and Quality of Services
	Advanced features with a simplified interface makes configuration a snap: Auto DoS Attack Prevention & Auto VoIP
	17.6 Gbps Non-blocking Switching Fabric for the fastest speeds
	Flexible 4 GbE Uplink Interfaces provide maximum speed between switches
