The XS505M and XS508M come with Copper Ethernet ports that provide either FastEthernet 1-Gigabit 2.5-Gigabit 5-Gigabit or 10-Gigabit connectivity as well as 1 SFP+ Fiber port with 1-Gigabit or 10-Gigabit connectivity. 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 XS505M gives the exact speed required no downgrade. Also the new NETGEAR Multi-speed switch ports can be connected with regular Cat5E Ethernet cables without the need to upgrade to Cat6 wiring therefore reducing wiring costs and hassle.
