Description

The EX4100-F is a compact, fanless Layer 2 and Layer 3 access switch from the Juniper EX4100 line. It suits branch offices, campuses and remote sites, particularly noise-sensitive or space-constrained access-layer deployments where silent operation matters.

This 12T variant provides 12 x 10/100/1000BASE-T access ports without PoE, plus 2 x 100M/1G/2.5G/5G/10GBASE-T uplink ports and 4 x 10G SFP+ ports that can be used as uplinks or Virtual Chassis connections. It offers an 80 Gbps backplane, 107 Mpps throughput and a maximum system power draw of 55 W. It ships with the Junos Base software feature set. Mist cloud management and Wired Assurance are optional subscriptions.

Up to 10 EX4100-F switches can be joined in a Virtual Chassis and managed as a single device. The SFP+ ports accept 10G optics, and the switch can be managed through Juniper Mist or the Junos CLI.

FAQs

Q: Does the EX4100-F-12T support PoE?
A: No. This model has no PoE ports and no PoE budget, so powered devices need a separate power source. Maximum system power consumption is 55 W.

Q: Which software licence does this model use?
A: It runs the Junos Base feature set. Mist cloud management and Wired Assurance are optional subscriptions and are not part of the base SKU.

Q: Can the SFP+ ports be used for stacking?
A: Yes. The 4 x 10G SFP+ ports support Virtual Chassis connections for up to 10 EX4100-F switches, or can be reconfigured as Ethernet uplink ports.

Q: How does the 12T differ from other EX4100-F models?
A: The 12T is the non-PoE, fanless 12-port variant with 2 x 10GBASE-T uplinks and 4 x 10G SFP+ ports. PoE-capable siblings are separate SKUs.

Q: How is the switch managed?
A: It can be managed through the Juniper Mist cloud platform or the Junos CLI, with zero-touch provisioning supported.
