What is the PoE capacity and port configuration of EX4300-24P?

EX4300-24P features 24x 10/100/1000BASE-T PoE+ ports with a 715W AC PSU providing 565W PoE budget. This supports up to 30W per port for devices like Wi-Fi APs and IP cameras, with autosensing and MDI/MDIX for easy deployment in campus wiring closets.

What performance metrics define the EX4300-24P switching capacity?

It delivers 448Gbps bidirectional data rate, 333Mpps wire-speed throughput, and 224Gbps unidirectional packet switching capacity with 64-byte packets. The single EX-PFE ASIC ensures non-blocking forwarding across all ports, ideal for bandwidth-intensive access layers.

How does Virtual Chassis work on EX4300-24P?

320Gbps backplane enables stacking up to 10 EX4300 switches as one logical device using dedicated QSFP+ VCPs. This provides unified management, GRES for hitless failover, and scales to 240x 1GbE ports with simplified cabling and LCD slot identification.

What uplink options are available on EX4300-24P?

Four integrated rear 40GbE QSFP+ ports support native uplinks or VCPs, with optional 4-port 1/10GbE SFP+ uplink module for flexibility. Supports SFP/SFP+ optics including SX/LX for multimode/single-mode fiber connectivity to aggregation layers.

Is the EX4300-24P suitable for data center top-of-rack?

Yes, its 1RU form, 333Mpps L2/L3 performance, and 40GbE uplinks make it effective for ToR access connecting servers to spine. Junos OS features like QoS, MAC limiting, and low latency suit east-west traffic in virtualized environments.

What resiliency features does EX4300-24P offer?

Includes internal hot-swappable redundant PSU option, field-replaceable fans, and GRES in Virtual Chassis for control plane failover. LCD panel displays alarms, slot number, and RE status for rapid troubleshooting in production networks.
