Description

The Juniper EX4100 is a fixed 1U non-PoE access switch for campus and branch networks, including DC-powered sites. This EX4100-48T-DC model is cloud-ready with Juniper Mist and supports 10-member Virtual Chassis and EVPN-VXLAN campus fabrics.

It provides 48 x 10/100/1000BASE-T RJ-45 ports, 4 x 1GbE/10GbE SFP+ MACsec-enabled uplink ports and 4 x 10GbE/25GbE SFP28 Virtual Chassis ports. Packet switching capacity is 188 Gbps unidirectional and 376 Gbps bidirectional, with 279 Mpps throughput. It has no PoE ports. This DC variant uses a 150 W DC power supply (JPSU-150-DC-AFO) with front-to-back (AFO) airflow, rated for -48 to -60 VDC input, and the chassis supports up to two power supplies for load-sharing redundancy.

The SFP+ uplinks run at 1GE or 10GE, while the SFP28 ports operate at 10GE or 25GE and serve as Virtual Chassis or stacking ports. The switch runs Junos OS 22.2R1 or later, and advanced features and Mist cloud management require software or subscription licensing.

FAQs

Q: Does this switch provide PoE?
A: No. The EX4100-48T-DC is a non-PoE model with 48 standard Gigabit copper ports. PoE-capable versions of the EX4100 are separate SKUs.

Q: What power does the EX4100-48T-DC need?
A: It uses a 150 W DC power supply (JPSU-150-DC-AFO) rated for -48 to -60 VDC input at 4.7 A to 2.8 A. The chassis supports up to two power supplies, which load-share when both are fitted.

Q: What is AFO airflow on this model?
A: AFO means front-to-back airflow, with the fan modules and power supply moving air out of the front of the switch. It suits racks arranged for front-to-back cooling.

Q: Does it need a licence for Junos features or Mist?
A: The switch runs Junos OS 22.2R1 or later. Advanced features and Juniper Mist cloud management (Wired Assurance) require software or subscription licences.

Q: What are the SFP28 ports used for?
A: The four 10GbE/25GbE SFP28 ports act as Virtual Chassis or stacking ports, supporting up to 10 members. The four SFP+ ports are 1GE/10GE MACsec-enabled uplinks.
