Description

The Juniper EX4400-24T-AFI is a fixed-configuration 1U access switch from the EX4400 Series. It suits large branch offices, campus wiring-closet access and data-centre top-of-rack, including campus-fabric (EVPN-VXLAN) and Virtual Chassis deployments.

The switch provides 24 x 10/100/1000BASE-T RJ-45 ports with no PoE, plus 2 x 100GbE QSFP28 uplink/Virtual Chassis ports. An optional extension module adds 4 x 1/10GbE SFP+ or 4 x 25GbE SFP28 ports. This AFI model uses back-to-front airflow with a 550 W AC power supply, and a second PSU slot allows optional redundancy. Virtual Chassis interconnect runs at 400 Gbps with up to 10 members managed as one logical device. MACsec AES-256 is supported in hardware and is enabled with the optional perpetual licence S-EX-MACSEC-C2-P, sold separately.

The 100GbE QSFP28 ports accept 100G and 40G optics and DACs, and they default to Virtual Chassis ports. The switch runs Junos OS and can be managed through Juniper Mist cloud or the Junos CLI.

FAQs

Q: Does MACsec need a licence on this switch?
A: MACsec AES-256 is supported in hardware on the RJ-45 ports. It is enabled with the optional perpetual licence S-EX-MACSEC-C2-P, which is ordered separately.

Q: Does this switch provide PoE?
A: No. The EX4400-24T-AFI is a non-PoE model, so it has no PoE budget and the 550 W AC supply powers the switch only.

Q: What does AFI airflow mean?
A: AFI is back-to-front airflow. Air is drawn in at the power and fan side and exhausted at the port side, which suits racks with ports facing the hot aisle.

Q: What can I connect to the 100G QSFP28 ports?
A: The 100GbE QSFP28 ports accept 100G and 40G optics and DACs. They default to Virtual Chassis ports, and a Virtual Chassis DAC is ordered separately.

Q: Can I add more uplink ports?
A: Yes. An optional extension module adds 4 x 1/10GbE SFP+ or 4 x 25GbE SFP28 ports.

Q: How many switches can be stacked together?
A: Up to 10 EX4400 switches can form a Virtual Chassis with a 400 Gbps interconnect, managed as one logical device.
