Data-centre spine and leaf switch

The Juniper QFX5110-48S-AFO2 is a 1U rack-mountable Ethernet switch built for high-density 10GbE, 40GbE and 100GbE connectivity in data centre spine and leaf topologies. It provides Layer 2, Layer 3 and MPLS features plus L3 gateway capabilities for bridging virtualised and bare-metal servers.

SFP+ and QSFP28 port limits

The chassis offers 48 SFP+ expansion slots for 10 Gigabit Ethernet and 4 QSFP28 uplink slots for 100 Gigabit Ethernet, all using optical fibre media. Total expansion slots reach 52, supporting 10GBase-X and 100GBase-X network technologies in a modular, manageable platform.

Front-to-back airflow with dual power supplies

The unit uses front-to-back cooling and accepts 120 V AC or 230 V AC input through up to two redundant power supplies, drawing 300 W. It fits a 1U rack space measuring 1.7 inches high, 17.4 inches wide and 20.5 inches deep, weighing 22.99 lb, and meets RoHS-6 and China RoHS environmental certifications.

Questions about this item

Should I pick the 48 SFP+ version or a model with fewer 10GbE ports?

The QFX5110-48S-AFO2 provides 48 SFP+ slots for 10GbE density plus four QSFP28 uplinks for 100GbE, giving maximum 10GbE port count in a 1U chassis.

What does the 300 W power draw mean for my rack power budget?

The switch consumes up to 300 W and supports dual redundant 120 V or 230 V AC power supplies, so plan for that load per unit in your PDU capacity.

How do the QSFP28 uplinks limit my 100GbE connectivity?

Four QSFP28 uplink slots carry 100GBase-X traffic, capping the switch at four 100GbE links while the 48 SFP+ slots handle 10GBase-X connections.
