Each port automatically detects which speed is needed by the connected device and provides the adequate speed. As opposed to regular 10-Gigabit switches that will only provide 1-Gigabit connectivity to any device that require less than 10-Gigabit,the switch gives the exact speed required,with no downgrade. Also,the NETGEAR Multi-Gigabit switch ports can connect regular CAT5e Ethernet cables,without the need to upgrade to CAT6 wiring,therefore reducing wiring costs and hassle. Access,aggregation or collapsed core:you can now have your PCs,printers and routers/firewalls connected at 1G and aggregate Multi-Gigabit Ethernet devices on the same switch,all line-rate. 10G copper and fiber ports are ready for local servers and storage,or high-speed aggregation to your network core.
