Engineering Context
The EX4650 brings 25GbE server access and 100GbE uplinks into a 1U Junos platform positioned for campus cores and data center access. The 48 SFP28 ports operate at 25GbE, 10GbE, or GbE depending on the inserted optic, and the 8 QSFP28 ports operate at 100GbE or 40GbE, letting the same chassis serve mixed-speed migrations. Juniper documents EVPN-VXLAN overlay support and Junos automation and telemetry on the platform.
Use Cases
25GbE server access with 100GbE uplinks in data center racks
Campus core or aggregation where 25G/100G capacity is replacing 10G/40G
EVPN-VXLAN fabric leaf deployments (verify feature licensing per Juniper policy)
Mixed-speed environments running 1G/10G/25G optics in the same SFP28 ports
What This Is NOT
NOT the AFI or DC variants. This is the AC-powered AFO (airflow-out, front-to-back) model; match airflow and power to your facility.
NOT a 400GbE / QSFP-DD platform. Uplinks are QSFP28 100GbE/40GbE.
NOT the EX4600. The EX4600 is a 1/10GbE + 40GbE platform; the EX4650 adds 25GbE SFP28 access and 100GbE QSFP28 uplinks.
NOT an RJ-45 copper access switch. All 48 access ports are SFP28 cages requiring optics or DACs.
NOT supplied with transceivers or DAC cables unless explicitly stated in the listing.
NO Juniper software licenses or support contracts are included or transferred; advanced features such as EVPN-VXLAN may require Juniper feature licenses per Juniper policy.
Compatibility & Hard Constraints
Optics and cables: Juniper-qualified SFP28/SFP+/SFP and QSFP28/QSFP+ optics and DACs; verify against the EX4650 hardware compatibility list.
Port rates: SFP28 ports support 25GbE/10GbE/GbE and QSFP28 ports support 100GbE/40GbE per the Juniper datasheet; breakout configurations must be verified for your Junos release.
Airflow: AFO — port-side intake, PSU-side exhaust; deploy with ports facing the cold aisle.
Software: Junos OS; confirm the installed release and upgrade path for required features.
Pre-deployment verification: confirm Junos release, feature licensing, PSU type, and airflow against the unit label.
Frequently Asked Questions (FAQ)
Q. What is the Juniper EX4650-48Y-AFO?
The EX4650-48Y-AFO is a 1U Juniper EX4650 switch with 48x tri-rate 25GbE/10GbE/GbE SFP28 ports and 8x 100GbE/40GbE QSFP28 ports, rated at 2 Tbps switching capacity, with two AC PSUs and front-to-back (AFO) airflow.
Q. Can the SFP28 ports on the EX4650-48Y-AFO run at 10GbE or 1GbE?
Yes. Per the Juniper datasheet the 48 access ports accept SFP28, SFP+, or SFP optics and operate at 25GbE, 10GbE, or GbE accordingly.
Q. Do the QSFP28 ports on the EX4650-48Y-AFO support 40GbE?
Yes. The 8 uplink ports are dual-rate 100GbE/40GbE QSFP28/QSFP+ cages. Breakout modes must be verified against Juniper documentation for your Junos release.
Q. What does AFO mean on the EX4650-48Y-AFO?
AFO denotes airflow-out cooling: port-side intake and PSU-side exhaust (front-to-back). Choose AFI models for the reverse direction.
Q. Does the EX4650-48Y-AFO support EVPN-VXLAN?
Juniper documents EVPN-VXLAN support on the EX4650 platform. Feature licensing requirements apply per Juniper policy and are not included with this unit.
