Juniper EX4600-40F-AFO Ethernet Switch

Description

The Juniper EX4600-40F-AFO is a compact, high-density 10GbE Ethernet switch designed for enterprise campus, data-center, and aggregation-layer deployments. Part of the Juniper Networks EX4600 family, it combines high-speed fiber connectivity, expansion flexibility, redundant components, and a compact 1U form factor.

The switch provides 24 SFP+/SFP ports for 1GbE or 10GbE connectivity and 4 QSFP+ ports that can provide high-speed 40GbE connectivity or be used for additional network capacity depending on the selected optics and configuration.

Two dedicated expansion slots provide additional flexibility for expanding network capabilities, while redundant fans and dual AC power supplies improve hardware availability and service continuity.

24 SFP+/SFP Ports

The EX4600-40F-AFO provides 24 SFP+/SFP ports, allowing organizations to deploy high-density fiber connections.

These ports can support compatible SFP or SFP+ transceivers, enabling flexible connectivity options based on the network requirements and selected optical modules.

Typical applications include:

• Server connectivity
• Switch-to-switch uplinks
• Fiber aggregation
• Data-center connections
• Enterprise backbone links
• Storage networking

The use of pluggable optics allows network administrators to select appropriate transceivers based on required speed, fiber type, distance, and network architecture.

Four QSFP+ Ports

The switch includes 4 QSFP+ ports for high-bandwidth uplink and aggregation requirements.

QSFP+ interfaces are commonly used for 40GbE connectivity, making them suitable for high-speed connections between aggregation switches, core switches, servers, and other network infrastructure.

These ports can provide additional network capacity for organizations migrating from 10GbE toward higher-speed infrastructure.

Expansion Flexibility

The EX4600-40F-AFO includes two expansion slots, allowing the switch to accommodate supported expansion hardware and provide additional connectivity or functionality depending on the selected configuration.

This modular approach helps organizations adapt the switch to changing network requirements without replacing the complete chassis.

Redundant Cooling

The EX4600-40F-AFO incorporates redundant fans to improve cooling reliability.

Redundant cooling is particularly important in data-center and enterprise environments where networking equipment is expected to operate continuously and where thermal management is critical.

The fan configuration helps maintain appropriate operating temperatures and provides additional resilience in the event of a fan failure.

Dual AC Power Supplies

The switch is supplied with two AC power supplies, providing a redundant power configuration.

Dual power supplies can be connected to separate power sources or circuits to improve system availability. If one power source or power supply becomes unavailable, the redundant configuration can help maintain switch operation.

This makes the EX4600-40F-AFO suitable for environments where network availability is a high priority.

Front-to-Back Airflow

The front-to-back airflow configuration is designed for data-center rack environments where equipment is typically arranged so that cool air enters from the front of the rack and heated air is exhausted toward the rear.

This airflow orientation can help integrate the switch into standard data-center cooling architectures.

High-Density Network Aggregation

With its combination of 10GbE-capable SFP+/SFP interfaces and high-speed QSFP+ connectivity, the EX4600-40F-AFO is well suited for network aggregation.

It can be deployed between access-layer switches and higher-level core or distribution infrastructure, providing a high-capacity aggregation point for multiple network connections.

Typical Applications

Data Centers
High-speed server, storage, and switch connectivity.

Enterprise Networks
