Juniper EX4650-48Y-AFO 48x SFP28 25GbE + 8x QSFP28 100GbE Switch 1U

Juniper EX4650-48Y-AFO — 25GbE/100GbE Campus and Data Center Switch

Technical Identity

The Juniper Networks EX4650-48Y-AFO is a 1U switch with 48x 25GbE/10GbE/GbE SFP28/SFP+/SFP ports and 8x 100GbE/40GbE QSFP28/QSFP+ ports, shipping with redundant fans, two AC power supplies, and front-to-back (AFO) airflow. Per the Juniper EX4650 datasheet the platform delivers 2 Tbps switching capacity and up to 1.49 Bpps forwarding, supports EVPN-VXLAN, and runs Junos OS. Condition: Refurbished.

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.
