1. Introduction
CERIO CS-2000 Series Model: CS-2424G is a powerful high-performance 4 SFP Gigabit 24
port 10/100/1000Mbps web managed switch and supports Remote control and management
through a web-based User Interface. This Layer 2 Web Managed switch supports Spanning
Tree / Rapid Spanning Tree protocol, Port base IEEE802.1Q VLAN Tagging, IGMP snooping,
IEEE802.1p port-based QoS, and Bandwidth control / Loop Detection. CS-2424G’s high
performance gigabit design provides reliable performance and allows for easy management of
auto-negotiation speeds.
The CERIO CS-2000 Series CS-2424G Web Managed Switch is ideal for minimizing network
downtime, connecting subnets for improved performance, and enabling the bandwidth
demanded for multimedia and imaging applications. CS-2424G effectively reduces operational
costs by allowing network administrators to remotely access and monitor their network,
ultimately eliminating the need for constant on-site maintenance staff. CS-2424G’s layer 2 web
managed design also increases network security by providing enhanced network control
through port management and visible MAC table addresses/clients. This device’s high feature
and high performance design, paired with an easy to use web interface, effectively improves
both network management and efficiency for medium and large sized applications
