Specifications

Description

The Juniper EX4550-EM-2QSFP is a high-performance expansion module built for the Juniper EX4550 Series Ethernet switches. It adds two 40GbE QSFP+ ports, enabling ultra-high-speed uplinks, stacking, or inter-switch connections. Supporting hot-swappable installation, this module enhances bandwidth without interrupting live network operations.
With support for virtual chassis, MPLS, QoS, Layer 2/3 protocols, and Junos OS integration, the module is ideal for enterprise networks and data centers requiring high-throughput, low-latency, and scalable connectivity.

Features

2x 40GbE QSFP+ ports — ideal for ultra-fast uplinks or stacking
Hot-swappable design — upgrade without disrupting network services
Compatible with EX4550 series (e.g., EX4550-32T, EX4550-32F models)
Supports Virtual Chassis technology for stacking up to 10 switches
Flexible deployment — use for spine-leaf, core-to-aggregation, or east-west traffic
Enterprise features — supports VLANs, MPLS, QoS, link aggregation, and access control
Seamless integration with Junos OS and existing EX4550 infrastructure
Compatible with various QSFP+ optics (not included; sold separately)

Specifications

Brand: Juniper
Model Number: EX4550-EM-2QSFP
Module Type: Expansion Module
Ports: 2x 40 Gigabit Ethernet QSFP+
Performance: Up to 40 Gbps per port (80 Gbps total)
Hot Swappable: Yes
Designed For: Juniper EX4550, EX4550-32T, EX4550-32F series
Transceivers: Not included (supports QSFP+ SR, LR, DAC, etc.)
Use Case: Uplinks, switch-to-switch backbone, Virtual Chassis stacking

Ideal Use Cases

High-Speed Uplinks: Connect EX4550 switches to core or spine switches with 40Gbps bandwidth for rapid data movement.
Virtual Chassis Stacking: Use 40GbE links as high-bandwidth interconnects in a Virtual Chassis cluster.
Data Center Interconnect (DCI): Efficiently link racks or zones with minimal latency and maximum throughput.
Enterprise Aggregation/Backbone: Aggregate multiple 10GbE links into a 40GbE backbone for cleaner, faster inter-switch traffic.
High-Density Virtualized Environments: Perfect for environments with high I/O demands such as cloud computing or big data analytics.

Why Choose the EX4550-EM-2QSFP?

Boosts bandwidth with 40GbE uplinks — ideal for modern workloads
Non-disruptive upgrades via hot-swappable module support
Ideal for stacking or uplink aggregation, especially in leaf-spine designs
Flexible deployment with wide QSFP+ optics compatibility
Integrated with Juniper's Virtual Chassis for simplified, resilient network management
Future-ready connectivity for growing data demands without chassis replacement
