Description

The Juniper EX4400-48F-AFI is a fixed 1U fibre access and aggregation switch from the EX4400 Series. It suits enterprise branch, campus and data centre deployments that need dense fibre connectivity, including campus fabric builds using EVPN-VXLAN.

The switch provides 36 x 100/1000BASE-X SFP ports and 12 x 1000/10000BASE-X SFP+ ports, plus 2 x 100GbE QSFP28 ports for Virtual Chassis or uplink use. Switching capacity is 456 Gbps unidirectional and 912 Gbps bidirectional. This is a non-PoE model with a 550 W AC power supply and back-to-front (AFI) airflow, with two PSU slots for 1+1 redundancy and two EX4400-FAN-AFI fan modules. A 2.2 GHz quad-core x86 CPU, 4 GB ECC DRAM and 20 GB of storage support Junos OS.

Extension module slots accept the EX4400-EM-1C (1x100GbE QSFP28), EX4400-EM-4S (4x10GbE SFP+) and EX4400-EM-4Y (4x25GbE SFP28) for additional uplinks. Virtual Chassis supports up to 10 members, and the platform requires Junos OS 21.1R1 or later.

FAQs

Q: Does this switch need a software licence?
A: It runs Junos OS, and advanced features use Juniper software licences. The MACsec AES-256 licence is a separate licence line item.

Q: Does it support PoE?
A: No. The EX4400-48F is a non-PoE fibre model, so it does not supply power to connected devices.

Q: What power supply and airflow does this SKU use?
A: It uses a 550 W AC power supply (JPSU-550-C-AC-AFI) with back-to-front AFI airflow. The chassis has two PSU slots for 1+1 redundancy.

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

Q: Can it be stacked?
A: Yes. Virtual Chassis supports up to 10 members over the 100GbE ports with a 400 Gbps interconnect.
