System compatibility
X440-48p belongs to Extreme Summit X440 stackable edge switch family. Compatible with Extreme validated 100BASE-FX / 1000BASE-X SFP transceivers. Managed via local CLI / web GUI. Widely used for enterprise campus, smart building PoE access for wireless APs, IP surveillance cameras and IP phones spare replacement.
Function
X440-48p is high-density stackable Layer3 gigabit PoE+ access switch. 48 PoE+ RJ45 ports deliver data and power to powered end terminals. Four combo SFP slots provide flexible gigabit fiber uplink. It supports static & dynamic routing, VLAN, STP/RSTP/MSTP, LACP link aggregation, ACL, QoS and multicast protocols. It monitors port link state, PoE power consumption, system temperature and fan health, and generates hardware fault alarms. Used for enterprise wiring closet high density PoE edge access networks.
Installation
Mount the switch on standard 19-inch 1U rack. Connect AC power cord. Insert SFP transceivers and fiber patch cords for fiber uplink if required. Connect console port for initial configuration and stacking setup. Verify boot,port link and PoE output function before commissioning.

DiagnosticSwitch fails to boot: Check AC power input and power supply health. PoE port no power: Verify PoE total budget,PD 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 peer device configuration. Low optical power alarm: Dirty fiber endfaces or damaged fiber cables. Transceiver undetected: Confirm Extreme compatible SFP module and correct insertion. Over-temperature alarm: Check fan operation and cabinet ventilation,clean dust buildup. Stack group split: Verify stacking cable and matched ExtremeXOS firmware version.
