1. Introduction
24+2G switch is a high performance web-managed SNMP Layer 2 switch that provides users with 24
10/100Mbps Ethernet and 2 1000Mbps Gigabit ports. This Switch has SNMP management and
remote control capabilities such as “Web Cluster”. The Gigabit module, which can be copper or fiber
media, supports 1000BASE-SX, 1000BASE-LX or 1000BASE-T, allowing users to increase their
network response time at gigabit speeds and with great flexibility. A RS-232 serial port provides an
easy way for installation and initial set-up.
Non-blocking and maximum wire speed performances are designed on all ports. The Switch not only
supports Auto-Negotiation, but also Auto-MDIX function on all switched 24 10/100M RJ-45 ports
and two Gigabit Copper ports in both half or full duplex mode. The Auto-MDIX function makes it
convenient for the user, because it eliminates cabling on straight-line or cross-line issues.
24+2G switch provides a convenient way to operate Layer 2 management through the browser. The
User-friendly drop-down menu allows the user to easily learn, control and monitor. It supports not
only traditional SNMP function, but also RMON 1,2,3,9 groups for advanced network analysis. A
new management tool called “Single IP” is implemented here to provide the administrator an access
right to enter private IP domain through a single real IP. By this management tool, network manager
can remotely control his far-side servers in private IP domain without being there.
The Switch also supports both port-based VLAN and Tag-based. To increase bandwidth application,
it supports 7 groups with up to 4 ports Trunk, and moreover, these trunk ports provide fair-over
function to provide back up when one or more ports malfunction. A stacking mode is introduced
here to enhance the ability of VLAN. An integrated UI not only displays the link status of the
stacking sets, but also gives the easy way to set up their VLAN.
Totally front access design and full LED status display ease user’s installation and inspection and
maintenance efforts at rack mount environments. The extra LED display reflecting the fan status
allows for quick diagnosis of over-heat issues.
