The Juniper EX4100-48MP delivers enterprise campus access for dense wired and wireless environments. With multigig connectivity and PoE support, it helps consolidate endpoints and improve capacity in busy shared areas while keeping the access layer simple to manage.
As endpoint counts rise and wireless demand becomes more concentrated, access layers need to carry more powered devices and higher-capacity traffic without adding switch sprawl.
The Juniper EX4100-48MP is an access switch for production networks that need high port density, PoE, and stronger wireless headroom in campuses, offices, and operational spaces. Its 48×Multigig ports and 1620 W PoE budget suit mixed edge builds where phones, cameras, and access points share the same closet.
With 4×SFP+ uplinks and support for up to 25G port speed, the platform gives network teams room to place more demanding devices without redesigning the access layer. Stacking support also helps keep closely related switches managed as a single operational domain.
This combination helps reduce split-switch planning, supports busier wireless zones, and creates a more flexible edge for mixed workloads. It is a practical fit where access density and PoE demands are both part of normal operations.
If you are planning a deployment around the Juniper EX4100-48MP, our team can help align the switch design to your port mix, power needs, and uplink requirements.
Juniper EX4100-48MP is an enterprise access switching platform for wired and powered edge deployments, designed to support modern campus environments with scalable network operations and resilient connectivity.
Multigig Access Layer
The switch provides 48 Multigig ports to support high-speed access for endpoints that need more than standard gigabit connectivity.
Power Delivery at the Edge
Built-in PoE support with a 1620 W budget enables the network to deliver power and data from a single access layer platform.
Uplink Aggregation
Four SFP+ uplinks provide dedicated high-speed connectivity for upstream switching and aggregation designs.
Stackable Architecture
Stacking support allows multiple switches to operate as a coordinated access system for broader campus deployment needs.
Integrated Platform Continuity
The stackable design helps preserve service continuity by extending control across multiple access switches in one operational domain.
Edge Power Planning
The high PoE budget supports consistent power allocation for connected devices across dense access environments.
Scalable Deployment Model
The platform is suited to growth at the edge by combining multigig access, uplink capacity, and stacking in one switch family.
If you are planning a campus refresh or high-density edge rollout, our team can help align Juniper EX4100-48MP design choices with access, power, and scaling requirements.

Juniper EX4100-48MP is an access switch for dense edge deployments that need many PoE connections and extra wireless headroom. It fits larger floors and shared spaces where endpoint count, camera traffic and AP performance must be balanced without moving into a higher-tier access platform.
On large hotel floors, the EX4100-48MP can consolidate room devices, cameras and access points in one closet while leaving multi-gigabit capacity for lobby or conference wireless. That helps avoid uneven coverage and port shortages during peak guest demand.
Healthcare teams can use it in larger ward and clinic closets where many powered endpoints share the same edge switch. The added multi-gigabit support is useful for busy clinical areas with high-capacity APs and fewer tolerance for bottlenecks.
In finance, this switch suits office floors with high user counts, VoIP handsets and meeting rooms, plus wireless zones that see heavier traffic. It gives teams a single access layer when gigabit-only switching starts to constrain performance.
Manufacturing sites often need one switch to feed cameras, terminals and APs across production-office edges and plant-floor cells. The EX4100-48MP supports that mix where mobile and IoT traffic can outgrow standard gigabit access.
For professional services offices, it provides a practical fit for desks, VoIP, AV and collaboration rooms from a shared access closet. The 48-port count reduces switch sprawl, while multi-gigabit ports protect busier meeting spaces.
We can help design and deploy Juniper EX4100-48MP access switching for hotel floors, clinical closets, office estates, plant edges and collaboration-heavy workspaces, aligned to your port count, wireless demand and recovery needs.
