Description

The Juniper EX4400-24X-DC is a fixed 1U Layer 3 switch from the EX4400 Series, built for enterprise campus and branch access, aggregation and distribution or core layers. The DC power input makes it a good fit for DC-powered sites such as telco and data centre environments, and for 10GbE fibre aggregation where MACsec-encrypted links are required.

It provides 24 x 1/10GbE SFP+ ports and 2 x 100GbE/40GbE QSFP28 uplinks, with hardware MACsec AES256 encryption. Switching capacity is 540 Gbps unidirectional (1080 Gbps bidirectional) with 803 Mpps Layer 2/Layer 3 throughput, and a 400 Gbps Virtual Chassis interconnect. This variant is non-PoE and uses a 550 W DC power supply (48-60 V DC input) with front-to-back (AIR OUT) airflow. It runs Junos OS, with the base feature set, from release 23.1R1.

An optional uplink extension slot accepts the EX4400-EM-4S (4x10G), EX4400-EM-4Y (4x25G) or EX4400-EM-1C (1x100G) modules. Sibling SKUs include the AC-powered EX4400-24X and the back-to-front airflow EX4400-24X-DC-AFI.

FAQs

Q: What licensing does the EX4400-24X-DC use?
A: It runs Junos OS with the base feature set. Advanced features such as EVPN-VXLAN and Juniper Mist cloud management require additional Juniper software licences or subscriptions.

Q: What power does this switch need?
A: It uses a 550 W DC power supply with a 48-60 V DC input. There are two hot-swappable load-sharing PSU slots. It is non-PoE and provides no PoE budget.

Q: Which optics and modules does it work with?
A: The 24 ports take 1/10GbE SFP+ optics and the two uplink ports take 100GbE/40GbE QSFP28 optics. The optional uplink modules are the EX4400-EM-4S, EX4400-EM-4Y and EX4400-EM-1C.

Q: How does this differ from the other EX4400-24X variants?
A: This SKU is DC-powered with front-to-back (AIR OUT) airflow. The EX4400-24X is AC-powered, and the EX4400-24X-DC-AFI is DC-powered with back-to-front airflow.

Q: Can it be part of a Virtual Chassis?
A: Yes. It supports a 400 Gbps Virtual Chassis interconnect and can form a Virtual Chassis with other EX4400 models.
