INTRODUCTION
The 3Com Baseline Switch 2824 and the 3Com Baseline Switch can operate in half or full duplex mode. At 1000 Mbps, the 2816 are versatile, easy-to-use switches. It is ideal for users who ports operate in full duplex mode only. want the high-speed performance of 10/100/1000 switching but do not need sophisticated management functions. The Switch is shipped ready for use. No configuration is necessary. Your 3Com Dual Speed Switch Baseline Switch incorporates the latest in Green technology to with 10/100 Mbps yield more than 25% power savings over the previous connection technology.
The Switch can be rack-mounted or free standing.
Your Switch includes: Switch 2824
One power cord
Rack mounting kit
Four standard height, self-adhesive rubber pads 1000Mbps Servers with connections This User Guide and warranty card 1000Mbps connections The Switch is powered from the AC mains supply. 10/100Mbps Switch with Gigabit Connection The Switch provides high performance switched connections to 10 Mbps, 100 Mbps, and 1000 Mbps hubs, switches, servers and workstations that need a dedicated switched link. The following figure illustrates one possible configuration. Each port has a shielded RJ-45 connector on the front panel. Each port is capable of operating at 10 Mbps, 100 Mbps or 1000 Mbps. The ports can automatically determine the speed and the duplex mode of the connected equipment and provides a suitable switched connection. At 10 Mbps and at 100 Mbps, the ports
