System compatibility

220-12t-10GE2 belongs to ExtremeSwitching 220 series. It can stack with other 220 series switches, maximum 4 units in one stack, managed by single IP address. Compatible with Extreme certified SFP+ optical modules and DAC cables. Supports Layer2 switching and Layer3 routing including static route and RIP, up to 64 static routes. Suitable for enterprise branch, computer room and wired access layer deployment without PoE demand.

Function

220-12t-10GE2 is compact stackable non-PoE gigabit switch for enterprise edge access network. 12 copper gigabit ports connect workstations, PCs and network devices. Two 10G SFP+ ports provide high-speed fiber uplink to aggregation switch. Stacking capability combines multiple physical switches as one logical device to simplify network management. It supports VLAN, MSTP/RSTP, 802.1X authentication, LLDP, QoS and traffic filtering. Widely used for office wired network, server room access and branch office network.

Installation

Mount the switch to standard 19-inch rack or place on desktop. Connect AC power cord. Use console cable for initial CLI configuration. Insert SFP+ transceiver and fiber/DAC cable for 10G uplink. Configure stacking parameters if multi-switch cluster required. Set VLAN and routing functions as needed. Verify port status and stack connection after power on.

DiagnosticSwitch no power: Check AC power cable and wall outlet voltage, inspect power supply connection. Port no link: Verify copper cable quality, auto-negotiation and peer device state. SFP+ uplink no link: Verify SFP+ module certification, fiber end face cleanliness and optical attenuation. Stacking abnormal: Confirm stacking configuration, same firmware version on all stack members and cable integrity. Temperature warning: Check ambient temperature and fan operation. Port link flapping: Inspect copper/fiber cable, auto-negotiation and peer device state.
