Resumen

Product Overview

The Juniper QFX5120-48T-AFO is a high-performance, 1U fixed-configuration top-of-rack data center switch designed for demanding leaf-spine architectures. It features 48 x 10GbE RJ-45 copper ports for server connectivity and 6 x QSFP28 uplinks supporting 40/100GbE speeds, delivering 2.16 Tbps bidirectional throughput and 1 Bpps forwarding performance. Optimized for front-to-back airflow (AFO), it supports Virtual Chassis configurations of up to 2 devices, making it ideal for scalable, high-density 10GbE/100GbE deployments in enterprise and cloud data centers.

Architecture & Performance

The QFX5120-48T-AFO offers wire-rate L2/L3 performance with extensive scale: 288k MAC addresses, 4094 VLAN IDs, 64k ARP entries, 351k IPv4 FIB prefixes, 172k IPv6 FIB prefixes, 64 LAGs (up to 64 ports per LAG), and jumbo frames up to 9216 bytes. It supports advanced features like MSTP (64 instances), VSTP (509 instances), and up to 4 mirroring sessions. Powered by a 2.2 GHz quad-core Intel CPU with 16 GB DRAM and 100 GB SSD storage, it runs Junos OS for reliable operations.

Port Configuration

48 x RJ-45 10GbE network ports for direct server attachments. 6 x QSFP28 uplinks for high-speed aggregation. Additional ports include 1 x RJ-45 console, 1 x RJ-45 management, 1 x USB Type A, 10 MHz port, and PPS port.

High Availability & Management

Supports Virtual Chassis with 2 devices. Redundant 4+1 fan modules and 1+1 PSUs, all hot-insertable/removable. Comprehensive environmental monitoring and Junos OS management.

Power, Cooling & Physical

Front-to-back airflow with 132 CFM. Dual hot-swap PSUs (AC: JPSU-650W-AC-AO, max 251 W; HVAC: JPSU-850W-HV-AFO, max 440 W). 1U chassis: 1.72 in (H) x 17.36 in (W) x 20.48 in (D), 24.25 lb fully loaded.
