the package is to rack mounting kitthese desktop switches are designed for soho and workgroup. provide 16/24 10/100 ports for computers in the workplace or server. on the switch can also connect the hub. all ports automatically detect the transmission speed (10 mbps or 100 mbps) of connected devices. the ports also automatically distinguish operating full- and half-duplex and flow-control support. both switches are easily upgradeable via auto uplink and provide a quick and safe way to enlarge the network. flow-control according to ieee 802.3x provides a direct connection between the server and the switch for fast, reliable data transfer. with 200 mbps in full-duplex operation, these switches provide your server to provide high-speed data channels with very small portions of data loss.device manages without a fan and are thus optimally suited for use also in the workplace or as a switchboard cables. using the supplied installation kit can be installed in 19-inch rack or shelf.high port density in a table format16x/24-fold higher data throughput compared with the hubauto mdi/mdix uplink on every port, no crossover cable neededfull-/half-duplex autonegotiationsecure store-and-forward switchingieee 802.3x flow control provides data8k mac address table200 mbit full duplex speed serverback-pressure in half-duplex operationthe integrated cable managementa cache of automatic allocation for each port
