Description

The EX4400-48F is a 1U fibre access and aggregation switch from Juniper's EX4400 line, built for enterprise campus, branch and data centre networks. It suits 10G and 1G fibre-attached endpoints, building distribution and MACsec-encrypted links.

Port density is 36 x 100/1000BASE-X SFP ports and 12 x 1/10GbE SFP+ ports, with two 100GbE QSFP28 ports for Virtual Chassis or uplinks. Switching capacity is 456 Gbps unidirectional (912 Gbps bidirectional) and the forwarding rate is 678 Mpps. This is the non-PoE variant with a 550 W AC power supply and AFO front-to-back airflow, which separates it from the back-to-front AFI and 550 W DC versions. The chassis has two PSU slots for redundancy and load sharing. MACsec AES-256 is supported on the SFP and SFP+ ports with an optional licence.

It works with 1G SFP and 1/10G SFP+ optics, and the 100GbE ports also accept 40GbE optics. An optional extension module adds 4 x 10GbE SFP+ or 4 x 25GbE SFP28 ports, and up to 10 units can be combined in a Virtual Chassis managed as one device.

FAQs

Q: Does the EX4400-48F need a licence for MACsec?
A: The hardware supports MACsec AES-256 on the SFP and SFP+ ports, but it needs an optional licence. It runs Junos with the base feature set included.

Q: Does this switch provide PoE?
A: No. The EX4400-48F is a non-PoE fibre model, so it has no PoE budget.

Q: What power supply does it use?
A: It uses a 550 W AC power supply. The chassis has two PSU slots for redundancy and load sharing.

Q: What is the difference between the -AFO and -AFI variants?
A: The -AFO has front-to-back airflow, while the -AFI has back-to-front airflow. A separate -DC version uses a 550 W DC supply.

Q: Which optics and modules does it work with?
A: It takes 1G SFP and 1/10G SFP+ optics, and the 100GbE QSFP28 ports also accept 40GbE optics. An optional extension module adds 4 x 10G SFP+ or 4 x 25G SFP28 ports.
