System compatibility

X440-G2-12t-10GE4 belongs to Extreme X440-G2 enterprise edge switch family. Compatible with Extreme validated 1G SFP and 10G SFP+ optical transceivers. Managed via local CLI / web GUI and ExtremeCloud IQ. Widely used for branch office, small wiring closet, factory workshop access network spare replacement.

Function

X440-G2-12t-10GE4 is compact non-PoE Layer3 stackable access switch. 12 gigabit RJ45 ports connect local network terminals. Four rear SFP+ ports work as 1G fiber uplink by default, and can be upgraded to 10G after activating license; two ports can be configured for stacking. It supports static & dynamic routing, VLAN, STP/RSTP/MSTP, Fabric Connect, LACP link aggregation, ACL, QoS and multicast protocols. It monitors port link state, optical DDM parameters, system temperature and fan health, and generates hardware fault alarms. Used for small branch office edge networks.

Installation

Mount the switch on standard 19-inch 1U rack or deploy on desktop. Connect AC power cord. Insert SFP/SFP+ transceivers and fiber patch cords. Connect console port for initial configuration, license activation and stacking setup. Verify boot,port link and routing function before commissioning.
