ZyXEL GS-1524/GS-1548 are 24/48-port L2 Gigabit switch with advanced Web-based management support, 
Auto VoIP
and it’s specially designed for SB/Enterprise networks where extra bandwidth and advanced QoS or 
security features are required. To cope with the diverse requirements of SB/Enterprise businesses, the ZyXEL 
Flexible 4 GbE Uplink Interfaces
GS-1524/GS-1548 Web-managed switch comes with 20/40 Gigabit copper ports plus 4 dual-personality (RJ-
IEEE 802.3ad Static Port  
 
 
45/SFP) Gigabit ports to provide 48/96 Gbps of non-blocking connectivity for SB/SMB networks. With the 
 Aggregation
flexible multi-function design, GS-1524/GS-1548 fits any network with very little effort.

IEEE 802.1Q VLAN
While many legacy Web-based Smart switches improve manageability, configuration complexity is still an 
Port security
issue; for most SB/Enterprise, inadequate IT expertise and complicated configuration are the major 
IEEE 802.1p with 4 Priority   
 
concerns to overcome. Powered by the next-generation hardware platform with a content-aware engine, 
 Queues
ZyXEL GS-1524/GS-1548 delivers stress-free networking. In addition, the streamlined and intuitive Web-GUI 
makes GS-1524/GS-1548 even easier to configure to slash the efforts needed.

Auto DoS Attack Prevention
Security is becoming increasingly important in SB/Enterprise networks. Equipped with Auto DoS Attack 
Prevention, the GS-1524/GS-1548 is capable of protection 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 GS-1524/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 Optimization
Migration to VoIP is the key to differentiate business competitiveness. It usually requires IT expertise to 
24-port/48-port 
optimize a network for VoIP applications. With emergence of the “Auto VoIP” feature, however, the GS-
Web Managed Switch
1524/GS-1548 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 
such as four priority queues and the WRR (Weighted Round Robin) scheduling algorithm are usually 
GS-1524
deployed on enterprise networks, allowing users to optimize network bandwidth usage and implement 
GS-1548
QoS (quality of service). In terms of bandwidth management and switch interconnections, users can choose 
from several options and pick the most appropriate with just a mouse click.
