System compatibility

220-12p-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 routes. Suitable for enterprise branch, classroom and wireless AP access layer deployment.

Function

220-12p-10GE2 is compact stackable PoE+ gigabit switch for enterprise edge access network. 12 PoE+ copper ports supply power and data to wireless APs, IP cameras and VoIP phones. Two 10G SFP+ ports provide high-speed fiber uplink to aggregation switch. Stacking capability combines multiple physical switches as one logical device to simplify management. It supports VLAN, MSTP/RSTP, 802.1X authentication, LLDP, QoS and traffic filtering. Fanless optional design is suitable for quiet office environment. Widely used for campus wireless access, IP surveillance 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, PoE power priority and routing functions as needed. Verify port status, PoE output and stack connection after power on.

DiagnosticSwitch no power: Check AC power cable and wall outlet voltage, inspect power supply connection. PoE port no power: Check PoE power budget, port PoE enable status and copper cable quality. 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, fan operation if fan equipped. Port link flapping: Inspect copper/fiber cable, auto-negotiation and peer device state.
