QFX5110-48S-AFO Overview
Exact AC and airflow identity
QFX5110-48S-AFO is the AC-powered, front-to-back airflow order of the QFX5110-48S. AFO means air exits from the port side toward the field-replaceable-unit side; do not mix it with AFI or DC variants in the same airflow plan.
Port and capacity boundary
Juniper identifies 48 SFP+ ports and four QSFP28 ports. The 48S platform supports 1/10GbE access and 40/100GbE high-speed interfaces; the selected optics, breakout mode and Junos release determine the usable link configuration.
Published platform scale
The Hardware Compatibility Tool lists a fixed 1U chassis, 1.76 Tbps bidirectional throughput, 1.32 Bpps forwarding capacity, five QFX5110-FANAFO fan modules, 16 GB DRAM and 64 GB SSD storage for this order.
Receiving and fabric acceptance
Match QFX5110-48S-AFO on the chassis, both AC supplies and every AFO fan. Record optic PIDs, port speeds, Junos image, EVPN or Virtual Chassis role, management reachability and a full link test. Reject mixed airflow modules and do not substitute a QFX5100-96S-DC-AFO based only on port count.
