Description

The EX4400-24T-DC-AFI is a fixed-configuration 24-port Gigabit Ethernet switch from the Juniper EX4400 line, built for campus and branch access or aggregation where DC power and back-to-front airflow are required.

It provides 24 x 10/100/1000BASE-T RJ-45 ports with no PoE, plus 2 x 100G QSFP28 ports for uplinks or Virtual Chassis stacking. An optional extension module adds 4 x 10G or 4 x 25G ports. The chassis is powered by a 550 W DC supply and uses AFI (back-to-front) airflow with two fan modules, which suits rear-aisle-cooled rack layouts. The 1U unit offers 880 Gbps of switching capacity and 660 Mpps of forwarding, and runs Junos OS from release 21.1R1. MACsec AES-256 is available through an optional licence.

Virtual Chassis over the 100G ports uses DAC cables, and the QSFP28 ports accept 100G optics and DACs.

Enquire with XS Network Tech for new or used pricing and availability.

FAQs

Q: Does this switch provide PoE?
A: No. The EX4400-24T-DC-AFI is a non-PoE model, so it has no PoE budget and will not power PoE devices.

Q: What power supply does it use?
A: It uses a 550 W DC power supply, so it needs a DC feed rather than a standard AC mains supply.

Q: What does AFI airflow mean?
A: AFI means back-to-front airflow. The two fan modules draw air in from the rear of the chassis, which suits racks cooled from the rear aisle.

Q: Can I stack this switch?
A: Yes. The 2 x 100G QSFP28 ports can be used for Virtual Chassis stacking, with DAC cables ordered separately.

Q: Is MACsec included?
A: The hardware is MACsec AES-256 capable, but MACsec is enabled through an optional licence sold separately.

Q: Can I add 10G or 25G ports?
A: Yes. An optional extension module adds 4 x 10G or 4 x 25G ports and is sold separately.
