Description

The Juniper EX4400-24T-DC is a fixed 1U access and distribution switch from the EX4400 line, built for branch and campus networks. It suits sites that run on -48 V DC supply, such as telecom rooms and industrial locations, and it also fits campus fabric deployments using EVPN-VXLAN.

This SKU provides 24 x 10/100/1000BASE-T RJ-45 ports with no PoE, plus 2 x 100GbE QSFP28 ports used for uplink or Virtual Chassis. An optional extension module slot adds 1x100GbE QSFP28, 4x10GbE SFP+ or 4x25GbE SFP28. It is powered by a 550 W DC supply with a 48-60 V input and front-to-back (AFO) airflow, with typical draw of 94 W idle and 99 W at maximum traffic. Packet switching capacity is 324 Gbps unidirectional. It runs Junos OS, and MACsec AES-256 is available with a licence.

The 100GbE QSFP28 ports accept 100G and 40G optics. Extension modules are EX4400-EM-1C, EX4400-EM-4S and EX4400-EM-4Y, and up to 10 members can be joined in a Virtual Chassis.

FAQs

Q: Does the EX4400-24T-DC provide PoE?
A: No. The 24T has 24 non-PoE Gigabit copper ports. Its 550 W supply powers the switch only.

Q: What power input does this model use?
A: It uses a 550 W DC power supply with a 48-60 V DC input. A second hot-swappable supply can be added for load-sharing redundancy.

Q: Does MACsec need a licence?
A: Yes. Hardware MACsec AES-256 is supported but requires a separate licence. The switch runs Junos OS under Juniper software feature licensing.

Q: What are the 100G ports used for?
A: The 2 x 100GbE QSFP28 ports are Virtual Chassis ports by default and can be used for uplinks. They accept 100G and 40G optics.

Q: Which extension modules does it work with?
A: EX4400-EM-1C (1x100GbE QSFP28), EX4400-EM-4S (4x10GbE SFP+) and EX4400-EM-4Y (4x25GbE SFP28).

Q: How does it differ from the EX4400-24T-DC-AFI?
A: The EX4400-24T-DC uses AFO front-to-back airflow, while the -AFI variant uses back-to-front airflow.
