ZyXEL ES-1528/ES-1552 come with 24/48 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 SMB/SB networks, 

and their multi-function design fit 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 around. For most 

SMB/SB, inadequate IT expertise and complicated configuration are the major pains to overcome before 

getting connected. Powered by newest hardware platform with smart ACL technology behind, “Auto DoS 

Attack Prevention” and “Auto VoIP” empowers hassle-free operations required by a network with strict 

protection and VoIP-friendliness. 

In addition, ZyXEL ES-1528/ES-1552 come with a streamlined intuitive Web-GUI for features demanded by 

SMB/SB; such as 802.1Q VLAN, 802.1p traffic priority and static port aggregation. Without awkward 

configurations and bulky user guide, the ES-1528/ES-1552 give real stuff for SMB/SB networks to enjoy the 

convenience.

Security is the top priority for SMB/SB networks. Equipped with Auto DoS Attack Prevention, the ES-1528/ 

ES-1552 are capable of fighting against ubiquitous DoS attacks. A few mouse clicks are all it takes to initiate 

the protection, complete the once-complicated ACL setting and reduce operating efforts dramatically. 

The ES-1528/ES-1552 support 802.1Q VLAN for traffic isolation, as well as Static MAC forwarding and 

dynamic ARP to establish a strictly protected network.

VoIP is a key to differentiate business competitiveness. It usually requires IT expertise to optimize a network 

for VoIP applications. With the emergence of the “Auto VoIP”, however, the ES-1528/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 WFQ 

scheduling algorithm allow users to optimize network bandwidth usage and quality of services. In term of 

bandwidth management, users can choose from several options and pick the most appropriate with just a 

mouse click.
