Dimension GS-2024
Affordability and Availability
ZyXEL Dimension GS-2024, a Managed Layer 2 Wiredspeed Gigabit performance switch, is a cost effective Gigabit
connectivity solution for the SMB and Enterprise LAN market.
With non-blocking 48 Gbps switching fabric, the GS-2024 provides 24-port 1000 Base-T Layer 2 switching capability at
wire-speed over current CAT-5 cabling to the desktops, as well as two open SFP slots providing fiber connectivity for long
loop reach applications.
High Performance
The highly effective switch architecture of ZyXEL GS-2024 offers 48Gbps non-blocking switch fabric, 35.7 million packet-
per-second forwarding rate and wire-speed performance. Ten times bandwidth than traditional Fast Ethernet that offer a
nearly wait network experience which is suitable for Today’s diverse E-Business applications. These benefits allow
customers to enjoy exceptional network speed with little effort.
Industry Standard-based Network Management
ZyXEL GS-2024 features a comprehensive set of network management interface, including Web-based management
interface, CLI management interface (Local/Remoter) and a built-in out-of-band MGMT RJ-45 port. User can easily
configure, troubleshoot and monitor switches through these methods.
The GS-2024 also supports ZyXEL iStackingTM a superior Web-based management software that allows administrators to
remotely manage multiple switches located differently. Administrators can configure, monitor, troubleshoot and manage
up to 24 switches at once with just one IP, regardless of the physical locations.
Enterprise-class Feature Set
With all ports support N-way auto negotiation and MDI/MDI-X crossover, the GS-2024 supports 802.1p priority queue,
802.1Q VLAN, port-based VLAN, 802.3ad port aggregation, 802.1w RSTP and rate limiting. Corporate IT users can also
benefit from the QoS and Security features of ZyXEL GS-2024. For traffic management, the GS-2024 supports IEEE 802.1p
that classifies and prioritizes network traffic by four independent queues. On security, the GS-2024 supports Specific MAC
Addresses Forwarding Per Port, which means only designated subscribers has the privilege to pass through the specific
ports. In addition, the GS-2024 also supports IEEE802.1x port authentication.
