Description

The EX4100-48MP is a 48-port multigigabit access switch from the Juniper EX4100 line, built for campus, branch and data-centre access. It suits deployments with Wi-Fi access points, IoT devices and multigigabit endpoints that need 802.3bt PoE++ power. Cloud management through Juniper Mist is available as an option.

The access layer provides 16 ports at 100M/1G/2.5GbE and 32 ports at 10M/100M/1GbE, and all 48 RJ-45 ports support PoE++ at up to 90 W per port. The PoE budget is 740 W with one power supply and 1620 W with two. Uplinks are 4 x 1/10GbE SFP+, and 4 x 10/25GbE SFP28 ports carry Virtual Chassis traffic. Switching capacity is 212 Gbps unidirectional (424 Gbps bidirectional) with 315 Mpps throughput. The 920 W AC AFO power supply gives front-to-back airflow in a 1U chassis.

Up to 10 members can be joined in a Virtual Chassis over the SFP28 ports. The switch runs Junos OS, and optics for the SFP+ uplinks are sourced separately.

FAQs

Q: Does this switch need a subscription to run?
A: It runs Junos OS. Cloud management through Juniper Mist Wired Assurance is optional and needs a separate subscription.

Q: How much PoE power does it provide?
A: The PoE budget is 740 W with one power supply and 1620 W with two. Every one of the 48 RJ-45 ports supports 802.3bt PoE++ at up to 90 W per port.

Q: What can I connect to the SFP+ and SFP28 ports?
A: The 4 SFP+ ports are 1/10GbE uplinks and need 1G or 10G optics. The 4 SFP28 ports run at 10/25GbE and are used for Virtual Chassis interconnects.

Q: Can I stack multiple units together?
A: Yes. Up to 10 members can be joined in a Virtual Chassis over the 10/25GbE SFP28 ports.

Q: How does this model differ from other EX4100 48-port variants?
A: The EX4100-48MP combines 16 multigigabit ports (up to 2.5GbE) with 32 x 1GbE ports, all with PoE++ at up to 90 W per port. It ships with a 920 W AC AFO power supply for front-to-back airflow.
