System compatibility

220-48p-10GE4 belongs to ExtremeSwitching 220 enterprise access switch family. Compatible with Extreme validated 1G SFP and 10G SFP+ optical transceivers. It supports stacking with other 220 series switches, can be managed via local CLI/web GUI or ExtremeCloud IQ cloud platform. Widely used for enterprise office, campus, hotel PoE access for Wi-Fi APs,IP surveillance cameras and IP phones spare replacement.

Function

220-48p-10GE4 is high-performance Layer3 gigabit PoE+ access switch. 48 PoE+ copper ports deliver data and power to powered terminal devices. Four dedicated SFP+ slots provide 10G high-speed fiber uplink to aggregation switches. It supports static routing,VLAN,STP/RSTP/MSTP,LACP link aggregation,ACL,QoS and multicast snooping. It monitors port link state,PoE power consumption,system temperature and fan health, and generates hardware fault alarms. Used for enterprise wiring closet PoE access networks requiring 10G uplink.

Installation

Mount the switch on standard 19-inch 1U rack. Connect AC power cable, redundant power supply can be installed for power redundancy. Insert SFP/SFP+ transceivers and fiber patch cords for fiber uplink. Configure stacking if multiple switches are required. Connect console port for initial configuration. Verify boot,port link,PoE output and stacking function before commissioning.

FeatureOriginal ExtremeSwitching 220 series 1U rackmount gigabit PoE+ Layer3 access switch,48 802.3at PoE+ ports plus four dedicated 10G SFP+ uplink slots,370W PoE budget,support up to 4 units stacking,optional redundant power supply,cloud & local dual management,smart fan cooling,built-in self-diagnostic function. This spare is suitable for enterprise access scenarios requiring high-speed 10G uplink.

DiagnosticSwitch fails to boot: Check AC power input and power supply health. PoE port no power: Verify PoE budget,PD device classification and port admin status. Copper port link down: Inspect RJ45 cable quality and auto-negotiation settings. SFP+ port no link: Check SFP+ transceiver,fiber cable and port configuration. Low optical power alarm: Dirty fiber endfaces or damaged fiber cables. Transceiver undetected: Confirm Extreme compatible SFP/SFP+ module and correct insertion. Over-temperature alarm: Check fan operation and cabinet ventilation,clean dust buildup. Stacking unstable: Verify matched firmware version and stacking cable connection.
