24-Port Managed Layer 3 Switch

Description

24 10/100Mbps Ports
The switch comes with 24 auto-sensing 10/100Mbps ports for direct connection to desktops.  With this high port density, you can easily group workstations together for intra-domain Layer 2 packet switching, or inter-domain Layer 3 local packet routing. 
 
2 Optional Gigabit Ports
An expansion slot allows for installation of 2 optional Gigabit ports, which are useful for Layer 3 switching.  These ports inter-connect the domains, routing packets to/from servers or other switches connected to the Gigabit backbone. Gigabit options installable include the fiber and twisted-pair copper Gigabit ports.  
 
Wire-speed IP Routing
The switch is designed for basic IP routing, with instant support for Windows, Unix and Internet environments. It provides wire-speed non-blocking switch fabrics with hardware-based packet filtering/forwarding.  Packet routing is performed by on-board ASICs at speeds many times faster than CPU-based routers.  
 
Ready for Voice, Video Applications
With Priority Queues and  IP multicast (IGMP snooping) support, Quality of Services (QoS) can be guaranteed for successful execution of delay-sensitive applications like videoconference and IP telephony. 

Easy Integration
With this switch, you can start with Layer 2 switching, then upgrade to Layer 3 routing anytime by simply re-configuring the ports.  The switch can be seamlessly integrated into any existing Ethernet network.  To filter extraneous traffic, your network can be segmented into (1) VLANs (Layer 2) with custom filters based on users' physical MAC addresses, or (2) domains (Layer 3) using subnet IDs and user IP numbers for packet routing.
 
Port Trunking
Port trunking provides an easy and economical alternative solution for server connection to attain near-Gigabit bandwidth.  Up to 8 10/100Mbps ports can be combined together to create a multi-link load-sharing trunk.  With low cost per port, domain servers can be cost-effectively connected on Fast Ethernet port trunks for wire-speed Layer 3 routing.  
 
Redundant Power Supply

The switch can operate with or without a redundant power supply.  For mission-critical applications, an optional RPS can be connected to the back of the switch to provide added reliability against power interruption risks.
