Function

5420F-48P-4XE is high-performance Layer3 gigabit PoE+ edge switch. 48 PoE+ copper ports transmit data and supply power to powered end devices. Four SFP+ ports support 1G/10G fiber uplink to aggregation layer; dual SFP-DD ports implement high-speed stacking. Hardware MACsec provides end-to-end link encryption. It supports static & dynamic 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 secure PoE access networks.

Installation

Mount the switch on standard 19-inch 1U rack. Connect AC power cable, optional secondary PSU for power redundancy. Insert SFP/SFP+ transceivers and fiber patch cords for uplink. Install SFP-DD stacking modules if stacking deployment required. Connect console port for initial configuration. Verify boot,port optical link,PoE output and stacking function before commissioning.

FeatureOriginal ExtremeSwitching 5420F series 1U rackmount gigabit PoE+ Layer3 edge switch,48 802.3at PoE+ ports plus four multi-rate SFP+ uplink slots,dual SFP-DD stacking interfaces,740W PoE budget,hardware MACsec encryption,cloud & local dual management,three built-in fan modules,built-in self-diagnostic function. This spare fits secure high-density enterprise edge access deployment.

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. MACsec negotiation failure: Verify MACsec security key and peer device configuration. Over-temperature alarm: Check fan modules running status and rack ventilation,clean dust buildup. Stacking failure: Verify matched firmware version and SFP-DD stacking module connection.
