Juniper EX4300-48P Overview EX4300-48P is a fixed-configuration 1RU Juniper EX4300 access switch designed for enterprise campus and service provider edge environments that require reliable Gigabit Ethernet PoE at the access layer. This model is commonly deployed in IDFs and wiring closets where power delivery to endpoints (wireless APs, IP phones, cameras, and IoT) is required alongside consistent Layer 2/Layer 3 access switching. The EX4300 family supports Juniper’s Virtual Chassis architecture for operational simplicity and scale. Key Hardware Characteristics Form factor: 1RU fixed-configuration switch Platform: Juniper EX4300 series Ports: 48 x 10/100/1000BASE-T (PoE ) PoE: 802.3at PoE for powered endpoints (budget varies by configuration) Operations: Virtual Chassis capable (stacking for simplified management) Network OS: Junos OS Operational Use Cases The EX4300-48P is typically used as a campus access switch where endpoint power and predictable switching behavior are required. Common deployments include powering wireless access points, VoIP phones, security cameras, and other PoE endpoints while providing stable access-layer connectivity back to distribution or core switches. In environments standardizing on Juniper campus designs, the EX4300-48P is frequently selected for sites that need PoE on most or all access ports without moving to a higher-cost chassis-based access platform. Related Variant If you don’t require PoE , the EX4300 family also includes non-PoE access models (for example, the EX4300-48T). For higher-powered or specialized access requirements, other EX4300 variants may be a better fit depending on endpoint power needs and uplink design.
