Description

The Juniper EX4100-48T is a fixed 1U non-PoE access switch from the EX4100 line, built for campus, branch and data centre access layers. It runs Junos OS and can be managed from the cloud with Juniper Mist or on premises, with EVPN-VXLAN campus fabric support for larger deployments.

It provides 48 x 10/100/1000BASE-T ports, 4 x 1/10GbE SFP+ MACsec-capable uplinks and 4 x 10/25GbE SFP28 ports used for Virtual Chassis stacking, allowing up to 10 members in one logical switch. Switching capacity is 188 Gbps unidirectional (376 Gbps bidirectional) at 279 Mpps. This variant has no PoE and uses a 150 W AC power supply with AFO (front-to-back) airflow, with a second internal slot available for 1+1 redundancy.

Uplink and stacking ports are SFP+ and SFP28, and the switch requires Junos OS 22.2R1 or later. It uses Juniper software subscription licensing, and Mist Wired Assurance is available as a separate subscription for cloud management.

FAQs

Q: Does the EX4100-48T support PoE?
A: No. This is a non-PoE model with 0 PoE ports, so it provides no PoE budget. Powered devices will need a separate power source or a PoE-capable model.

Q: How do I stack multiple units?
A: Use the 4 x 10/25GbE SFP28 Virtual Chassis ports. Up to 10 members can be combined into a single Virtual Chassis.

Q: Which airflow direction does this model have?
A: AFO, which is front-to-back airflow (air out at the rear), using two fan modules.

Q: Which Junos OS version does it need?
A: The EX4100 family requires Junos OS 22.2R1 or later. It uses Juniper software subscription licensing, and Mist Wired Assurance is a separate subscription for cloud management.
