The Juniper EX4100-48T delivers managed access for enterprise campus networks where wired endpoints need reliable connectivity without PoE overhead. With stacking support and hot-swappable PSUs, it helps keep office and back-office environments resilient and easier to scale.
As wired access layers expand to support more fixed endpoints, infrastructure teams need dense, manageable connectivity that fits the room and the budget without adding unnecessary complexity.
The Juniper EX4100-48T is a 48-port access switch for production networks that need reliable RJ45 1G connectivity across office floors, back-office areas, dispatch desks, and control rooms.
Its non-PoE design keeps the platform aligned to environments where PCs, printers, terminals, and test equipment already have local power. SFP+ uplinks and stacking support help it slot into wider access architectures without complicating day-to-day operations.
That combination gives IT a practical way to add port density, standardise access, and avoid spending on power capacity that would remain unused. It also supports cleaner expansion when teams need more wired endpoints on the same access layer.
If the Juniper EX4100-48T matches your access-layer requirement, our team can help you assess fit and plan deployment.
Juniper EX4100-48T is a campus access switch designed for enterprise edge deployments, providing a platform for building scalable wired access infrastructure in distributed environments.
Access Layer Design
The switch is positioned for campus access use cases, aligning wired connectivity with enterprise edge access requirements.
Enterprise Port Mix
It provides 48 RJ45 1G access ports and 4 SFP+ uplinks to support user and aggregation connectivity in one platform.
Wired Edge Consolidation
The access-oriented design supports endpoint attachment and upstream handoff within a single switching layer for campus deployments.
Deployment Fit
Its campus deployment profile makes it suitable for structured access switching where predictable network placement matters.
Infrastructure Standardisation
A defined access-switch role helps maintain consistent edge design across campus network builds and refresh cycles.
Uplink Integration
The SFP+ uplink interfaces provide upstream connectivity options for integrating the access layer into the wider network fabric.
Lifecycle Flexibility
The platform can be applied across new and refurbished deployments, supporting consistent product selection for different procurement models.
When you need to align campus access switching with your network design, our team can help match the EX4100-48T to your connectivity and deployment requirements.

The Juniper EX4100-48T is a 48-port managed copper access switch for wired office and operations environments where endpoints already have local power. It is a practical choice for dense 1GbE access layers that do not need PoE.
In professional services offices, IT teams often need high-port wired access for PCs and printers across busy floors. The EX4100-48T keeps the access layer cost-focused by avoiding unused PoE capacity.
Finance teams typically run fixed terminals, shared printers and audit workstations on stable wired connections. This switch fits those areas where security, consistency and auditability matter more than endpoint power delivery.
Healthcare estates often separate non-clinical offices from PoE-heavy clinical zones. The EX4100-48T supports records and admin spaces with dense wired connectivity, keeping local IT operations simpler and better contained.
Logistics sites need reliable ports for depot PCs, label printers and fixed terminals in office and dispatch areas. This model gives those spaces plenty of copper connectivity without spending budget on powered ports.
Manufacturing environments use wired PCs and test equipment in control rooms and engineering areas where devices already have local power. The EX4100-48T delivers 48-port density while avoiding unnecessary PoE overhead.
Our team can help design and deploy Juniper EX4100-48T access layers for office floors, finance back offices, healthcare admin spaces, logistics hubs and manufacturing control areas.
