System compatibilityB3G124-48P belongs to Extreme Networks B3 stackable switch family, formerly Enterasys. Multiple B3 units can be stacked together via dedicated stacking ports. Compatible with Extreme validated 1G SFP transceivers and fiber patch cords. Widely used for enterprise campus access, IP phone and wireless AP deployments.

FunctionB3G124-48P is a high-performance Layer3 managed gigabit PoE access switch. It supports static routing, VLAN segmentation, STP/RSTP/MSTP, LACP link aggregation, ACL, QoS, IGMP snooping and SNMP monitoring. It automatically detects powered devices and allocates PoE power budget. It monitors port link status, transceiver DDM optical data, chassis temperature, fan speed and power supply health. Used to build stacked resilient gigabit PoE access networks for campus buildings.

InstallationMount the switch on 19-inch 1U rack. Connect AC power cord; external EPS-C2 redundant power supply is optional. Insert SFP transceivers and fiber cables for uplink. Connect Cat5e/Cat6 cables to PoE RJ45 ports. Connect DB9 serial console port for EOS configuration. Verify boot sequence, port link and PoE status before putting into production.

FeatureOriginal Extreme Networks B3 series 1U rackmount 48-port gigabit PoE stackable Layer3 switch, combo SFP uplink design, dedicated high-speed stacking ports, transceiver DDM monitoring, external redundant power support,EOS operating system,built-in self-diagnostic function. This spare supports enterprise voice, wireless AP and IP camera access network deployment.

DiagnosticSwitch fails to boot: check AC power cord and wall power supply. PoE port no power: verify PD detection, total PoE budget and port enable status. Port link down: check Cat5e/Cat6 cable, SFP transceiver and port admin status. Transceiver no DDM data: confirm Extreme validated SFP transceiver. Stacking failure: verify consistent firmware version among stacked B3 switches. Over-temperature alarm: inspect chassis ventilation and clear dust.

Product BriefB3G124-48P is Extreme Networks 1U rackmount 48-port gigabit PoE stackable managed Layer3 switch with 4×combo SFP uplink and dedicated stacking ports, classic spare part for enterprise wiring closet PoE access network overhaul.
