Juniper EX4300 4‑Port 1GbE/10GbE Uplink Module

The Juniper EX‑UM‑4X4SFP is a modular uplink expansion card engineered to enhance connectivity for the Juniper EX4300 Series Ethernet switches. This flexible module provides four ports that support both 10 Gbps SFP+ and 1 Gbps SFP optics, enabling network architects to tailor uplink capacity to specific throughput demands using a mix of high‑speed and standard fiber or copper transceivers.

Designed for scalability, the EX‑UM‑4X4SFP installs directly into the dedicated uplink slot on compatible EX4300 chassis, giving network administrators the flexibility to add or upgrade uplink bandwidth without replacing the entire switch. Its hot‑plug design allows for insertion or removal without powering down the host switch, minimizing operational disruption during upgrades.

This uplink module broadens the versatility of the EX4300 platform in enterprise campus, data center aggregation, or service provider edge deployments by enabling connectivity diversity — supporting both high‑speed 10 GbE optical links and more conventional 1 GbE interfaces as required by the network topology.

Key Features:
• Four 10 Gbps SFP+ / 1 Gbps SFP configurable uplink ports for flexible deployment.
• Hot‑swappable plug‑in form factor for easy installation and field upgrades.
• Compatible with a wide array of SFP/SFP+ transceivers for fiber or copper links (transceivers sold separately).
• Enhances uplink capacity and scalability on EX4300 Switch Series.
• Supports high‑speed connectivity for enterprise and data center edge networks.
