Introduction
Easily boost your networking throughput, the rack-mountable switch provides you 24 10/100/1000Mbps
ports that lead you to a real Gigabit connection. Users are now able to transfer large and high
bandwidth-needed files faster and hence get a real efficiency improvement. In addition to the cooper ports,
2 ports support fiber connection with the 2 equipped Mini-GBIC ports for obtaining long-distance
communication.
The switch offers users with fast and reliable network. The store-and-forward architecture filters errors and
forwards packets in a non-blocking environment. Flow control ensures the correctness of data transmitting.
The 802.3x and backpressure flow control mechanisms work respectively for full and half duplex modes.
The switch features with easy installation and maintenance. It supports N-Way auto-negotiation protocol,
which detects the networking speed (either 10/100/1000 Mbps) and the duplex modes (Full or Half duplex
mode) automatically and do an immediately adjustment to advance the capability and performance.
Auto-MDI/MDI-X function alleviates the effort to use crossover cables. Users need not to prepare
crossover cables for equipment connectivity. Also, rich diagnostic LEDs are provided for users to get
real-time information of the connection status that helps to do quick response and correction.

RJ-45 Ports
All the RJ-45 ports in the device are auto-negotiating and auto-crossover. An auto-negotiating port can
detect and adjust to the optimum Ethernet speed (10/100/1000 Mbps) and duplex mode (full duplex or half
duplex) of the connected device. An auto-crossover (auto-MDI/MDI-X) port automatically works with a
straight-through or crossover Ethernet cable.
Mini-GBIC Slots
There are two slots for mini-GBIC (Gigabit Interface Converter) transceivers. You can plug the SFP port
modules into the switch. The SPF port modules are to be used with fiber-optical transceiver cabling in
1 V1
