Unmanaged Switch Juniper EX4100-48MP 48 Ports PoE 1U Grey

The Juniper EX4100-48MP is an unmanaged 1U Ethernet access switch with 48 RJ-45 ports and Power over Ethernet (PoE) capability, designed for enterprise campus, branch, and data center access environments. It provides a switching capacity of 376 Gbit/s and supports advanced networking standards. Although the device can be managed as part of Juniper’s EX4100 family when paired with cloud services, this specific model is sold as an unmanaged switch suitable for providing reliable wired connectivity and PoE power to endpoints such as phones, cameras, and access points.

Advantages

This switch offers high-density 48-port connectivity with PoE/PoE+/PoE++ support and a total PoE budget capable of serving power-hungry devices. It follows industry standards for Ethernet and PoE, supports 10G uplinks, and uses the EX4100 platform design that allows Virtual Chassis configurations and compatibility with Juniper features in managed deployments. The unit’s grey 1U form factor and a MAC address table sized for typical enterprise needs make it suitable for rack installations where space and power delivery are important.

Suitable for

• Office and campus wired access where multiple PoE endpoints (IP phones, Wi‑Fi 6 APs, surveillance cameras) are required
• Branch and small data center top-of-rack deployments that need high port density
• Environments requiring 10G uplink support for aggregation

How to use

Install the EX4100-48MP in a standard 19-inch rack using its 1U mounting brackets. Connect power and attach Ethernet cables to the RJ-45 ports for endpoints. Use the 10G-capable uplink ports to connect to aggregation or core switches. Because this model is unmanaged, configuration is minimal: connect devices and verify link/activity LEDs to confirm connectivity and PoE power delivery. For deployments requiring cloud management, consider pairing with Juniper-managed EX4100 models and Juniper Mist Wired Assurance where applicable.

Recommendations

Place the switch in a ventilated rack space and ensure the total PoE power draw of connected devices does not exceed the available power budget. Verify compatibility of powered devices with IEEE PoE standards and use 10G uplinks for high-throughput aggregation. For network monitoring or advanced features, use a managed EX4100 model or integrate this switch into a Virtual Chassis with compatible EX4100 units where management is required.
