The QFX5100-48T-AFI is a high-performance data center switch from Juniper featuring 48 100M/1G/10G Base-T ports, 6 QSFP ports, redundant fans and power supplies, and front-to-back airflow to support demanding enterprise and cloud environments.
It provides 48 Base-T ports that auto-negotiate 100 Mbps, 1 Gbps, or 10 Gbps, plus 6 QSFP uplink ports for 40 Gbps connectivity, allowing flexible server and spine links.
The switch includes dual, hot-swappable AC or DC power supplies and redundant, front-to-back cooling fans, enabling uninterrupted operation during component maintenance or failure.
With a 1.44 Tbps backplane and up to 1.07 billion packets per second (bpps) forwarding performance, the QFX5100-48T-AFI handles large east-west data flows with low latency.
It uses front-to-back airflow, drawing cool air in from the front and exhausting warm air out the back, optimized for hot-aisle/cold-aisle data center layouts.
It runs Juniper’s Junos OS, offering consistent CLI, automation APIs, modular architecture, and a rich feature set for Layer 2/Layer 3 protocols.
Yes, it supports Virtual Chassis technology, allowing you to interconnect up to 10 QFX5100 switches and manage them as a single logical device for simplified operations.
It supports VLAN, VXLAN, MLAG, Spanning Tree, OSPF, BGP, IS-IS, VRF-Lite, and advanced MPLS capabilities, delivering full data center fabric flexibility.
Management options include Junos CLI, Junos Space, Juniper Network Director, REST APIs, Ansible modules, and native Python scripting for end-to-end network automation.
Six QSFP ports support 4×10 GbE breakout or native 40 GbE, enabling spine-leaf architectures with flexible uplink speeds.
No, the QFX5100-48T-AFI does not provide PoE or PoE+; it is optimized for data center leaf and spine deployments where power over Ethernet is not required.
Ideal use cases include top-of-rack leaf switches, campus aggregation, NFV infrastructure, and spine-leaf fabrics in cloud and enterprise data centers.
In typical operation, the switch consumes around 250 W; maximum power draw with all modules and fans installed is approximately 350 W, depending on environment.
Operating temperature ranges are 0 °C to 40 °C (32 °F to 104 °F), with relative humidity from 5% to 90% non-condensing, suitable for standard data center conditions.
Yes, Juniper provides a limited lifetime hardware warranty and offers optional support tiers through Juniper Care for software updates, 24×7 support, and advance replacement.
