ZyXEL ES-1528 仕様ガイド

ZyXEL ES1528/ES1552 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 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, “Auto DoS 

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

security protection and VoIP-friendliness. 

In addition, the ZyXEL ES1528/ES1552 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 ES1528/ES1552 provides valuable features and 

convenience for SMBs.

ZyXEL is highly aware that network security is a top priority for SMBs and have therefore enable the 

ES1528/ES1552 to effectively combat DoS attacks. A few mouse clicks is all it takes to initiate protection, 

handling the once-complicated ACL setting and dramatically reducing operational issues.

The ES1528/ES1552 supports 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 ES1528/ES1552 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. In 

terms of bandwidth management, users can choose from several options and pick the most appropriate 

with just a mouse click.
