Juniper EX4600-40FAccess Switches

Enterprise-Class Network Backbone: High-Performance Juniper EX4600-40F Managed Ethernet Switch.

The Juniper EX4600-40F is a high-performance, data center-class managed Ethernet switch engineered for enterprise, campus, and modern data center deployments. It delivers ultra-high throughput with 24×10 GbE SFP+ ports and 4×40 GbE QSFP+ uplinks, all powered by Juniper’s Junos OS — a solid, secure, and programmable networking operating system. With support for Virtual Chassis technology, advanced Layer 2 and Layer 3 routing, MPLS, and high availability features, the EX4600-40F scales to support demanding workloads and resilient network topologies. Redundant power supplies and cooling, flexible airflow options, and expandable uplink modules make this switch a versatile choice for enterprise edge, aggregation, and core fabrics.

Model: EX4600-40F

Key Features & Highlights

Ports & Connectivity

• 24 × 10 GbE SFP+ ports — high-speed fiber connections for servers, aggregation, or data center access.

• 4 × 40 GbE QSFP+ ports — high-capacity uplinks, Virtual Chassis links, or backbone connectivity (each can also breakout to four 10 GbE ports with breakout cables).

• 2 Expansion Slots — for optional uplink modules like additional 40 GbE QSFP+ or 8×10 GbE modules (sold separately).

• Management & Console Ports: 1 RJ-45 management, 1 SFP management + console port.

Performance & Capacity

• Switching Capacity: ~1.44 Tbps (bidirectional) — very high throughput for modern networks.

• Forwarding Rate: ~1.07 Bpps (billion packets per second) at wire-speed performance.

• MAC Address Table: High capacity for large enterprise networks (often reported many thousands).

• VLAN Support: Up to 4,096 VLANs for segmentation.

• Jumbo Frame Support: Up to ~9,216 bytes.

Layer 2 / Layer 3 & Software Capabilities

• Full Layer 2 features: VLANs, STP/RSTP/MSTP, Link Aggregation (LACP), QoS, ACLs and more.

• Layer 3 routing: Static routes by default; full routing (OSPF, BGP, IS-IS) available depending on Junos feature set.

• Virtual Chassis Technology: Stack up to 10 EX4600 switches as a single logical device — simplifies scaling and management.

• High Availability & Resiliency: Features like GRES/NSR/NSB, ISSU, and redundant power/fans keep networks up in fault scenarios.

• Advanced Networking: MPLS, FCoE support, MACsec ready hardware (license/software dependent).

Hardware & Design

• Form Factor: 1 RU rack-mountable chassis.

• Airflow Options: Front-to-back or back-to-front for proper cooling in various data center setups.

• Power: Dual, redundant, hot-swappable PSUs included (options for AC or DC).

• Fans: Redundant, variable-speed and hot-swappable.

• Dimensions: ~1.72″ H × 17.36″ W × 20.48″ D.

• Weight: ~21.7 lbs (9.84 kg) with PSUs & fans installed.

Typical Use Cases

• Campus distribution & core networks requiring very high throughput.

• Data center top-of-rack (ToR) or aggregation layers.

• Scalable enterprise networks with Virtual Chassis stacking across multiple switches.

• Environments needing advanced Layer 3 routing, MPLS, or secure segmentation.
