Frequently Asked Questions

What does the F suffix mean in EX4100-F-12T?

The F suffix in EX4100-F-12T indicates the fanless model — silent operation suitable for quiet office environments where fan noise is unacceptable.

Does the EX4100-F-12T support PoE?

Yes — select RJ-45 ports support IEEE 802.3at PoE+ for powering IP phones, Wi-Fi access points, and IP cameras. Verify total PoE budget for your deployment.

Can EX4100-F-12T switches be stacked?

Yes — via Juniper Virtual Chassis, multiple EX4100 switches operate as a single logical managed device for simplified administration and redundancy.
