Juniper Networks EX4400-EM-4S Uplink Expansion Module – 4x 10GbE SFP+ Ports for EX4400 Series (Hardware Only, Optional 1–3 Year Support)

Description

The Juniper Networks EX4400-EM-4S is a high-performance uplink expansion module designed specifically for the EX4400 Series Ethernet switches. This module provides enhanced network scalability by adding four 10 Gigabit Ethernet SFP+ ports. As a result, it enables flexible high-speed uplink connectivity for enterprise campus and branch deployments.

Engineered for seamless integration, the EX4400-EM-4S installs directly into the dedicated expansion slot on compatible EX4400 switches. This allows organizations to scale bandwidth and improve aggregation capacity without replacing existing hardware. Furthermore, it supports both 1GbE and 10GbE speeds via SFP+ interfaces. This offers flexibility for mixed network environments and gradual infrastructure upgrades.

The module is ideal for connecting access switches to aggregation or core layers. It supports high-throughput applications such as cloud services, VoIP, video streaming, and large data transfers. With four SFP+ ports, it enables fiber uplinks over long distances using compatible transceivers. This ensures reliable and high-speed communication across distributed networks.

Weighing approximately 0.09 kg (0.2 lb), the EX4400-EM-4S is lightweight and designed for easy installation and maintenance. It is fully supported on EX4400 platforms running Junos OS. Therefore, it ensures consistent performance, advanced Layer 2/Layer 3 functionality, and compatibility with Juniper’s automation and management ecosystem.

As part of the EX4400 modular ecosystem, this uplink module enhances network flexibility. It allows organizations to adapt to growing bandwidth demands while maintaining cost efficiency and operational simplicity.

Optional Juniper Care support services (1-Year, 3-Year, or 5-Year) are available. They provide 24/7 technical support, software updates, and hardware replacement to ensure uninterrupted network operations.
