It provides 48 SFP28 ports at 25 GbE and 8 QSFP28 ports at 100 GbE, delivering flexible bandwidth options for spine-and-leaf architectures.
What does “port side intake and PSU side exhaust” airflow mean?
Port side intake means cool air enters through the front-facing ports, and PSU side exhaust directs warm air out the rear power-supply side, matching front-to-back data center airflow.
What is the switching capacity and throughput of this model?
The EX4650-48Y-AFO delivers up to 3.2 Tbps of switching capacity and forwards at up to 2.38 Bpps, ensuring low-latency packet processing at scale.
Which power supplies are supported and what is the typical power draw?
It supports dual redundant AC power supplies (AC-560W or AC-875W) and consumes approximately 300–450 W under full load, depending on traffic and optics.
What are the dimensions and rack space requirements?
The switch occupies 1U of rack space, measures 438 mm (W) × 438 mm (D) × 43.6 mm (H), and fits standard 19-inch server racks.
What environmental conditions does the EX4650-48Y-AFO require?
It operates between 0 °C and 45 °C with 5%–90% non-condensing humidity and is rated for standard data center air-conditioning and airflow patterns.
