Description

The Juniper EX4100-48P is a fixed 1U cloud-ready access switch from the EX4100 line, built for enterprise branch and campus access layers. It suits PoE+ powered endpoints such as IP phones, cameras and Wi-Fi access points, and is managed through Juniper Mist AI with EVPN-VXLAN campus fabric support.

It provides 48 x 10/100/1000BASE-T PoE+ ports delivering up to 30 W per port, plus 4 x 1/10GbE SFP+ uplinks and 4 x 10/25GbE SFP28 ports that can be used for Virtual Chassis or uplinks. The PoE budget is 740 W with one power supply and 1440 W with two. This SKU uses 920 W AC power with front-to-back (AFO) airflow, and the switch delivers 188 Gbps unidirectional switching capacity and 279 Mpps throughput.

Up to 10 units can be combined into a Virtual Chassis over a 200 Gbps interconnect. The SFP+ ports support MACsec, and the base SKU is listed with Standard software. Optional Juniper Mist Wired Assurance subscriptions are available for cloud management.

FAQs

Q: What PoE budget does the EX4100-48P provide?
A: The PoE budget is 740 W with one power supply and 1440 W with two. The 920 W AC power supply (JPSU-920-AC-AFO) is the one this SKU uses, and PoE+ delivers up to 30 W per port.

A: The base SKU is listed with Standard software. Optional Juniper Mist Wired Assurance subscriptions are available if you want cloud management.

Q: What can the SFP28 ports be used for?
A: The 4 x 10/25GbE SFP28 ports can be used for Virtual Chassis stacking or as uplinks. Up to 10 members can be combined in a Virtual Chassis over a 200 Gbps interconnect.

Q: What is the difference between the EX4100-48P and the EX4100-48P-TAA?
A: The EX4100-48P-TAA is the TAA-compliant variant of this model. It is a separate SKU.

Q: Can I add a second power supply?
A: Yes. The chassis has two load-sharing hot-swappable internal PSU slots, and adding a second 920 W AC supply raises the PoE budget from 740 W to 1440 W.
