28 port Gigabit Ethernet switch with 4x GbE/10GbE uplink ports

28 port Gigabit Ethernet switch with 4x GbE/10GbE uplink ports
28 port Gigabit Ethernet switch with 24x 100/1000MBit/s Fast / Gigabit Etherne SFP slots and 4x 1GbE / 10GbE SFP+ uplink ports. The switch is suitable as central hub for a flexible fiber optic connection with diverse transmission speeds. 4 of the 24 Gigabit Ethernet ports are equipped with RJ-45 sockets for local server connections. Four 10 Gigabit Ethernet ports enable the uplink to central backbone distributors or powerful servers.
