Description

The EX4400 48-port fibre switch is a fixed 1U Layer 3 access and aggregation switch from the Juniper EX4400 line. It suits enterprise branch, campus and data centre networks that need secure, cloud-ready fibre connectivity, including campus fabric deployments using Virtual Chassis and EVPN-VXLAN.

This SKU provides 12 x 1/10GbE SFP+ ports and 36 x 100M/1GbE SFP ports, plus two 100GbE QSFP28 ports for Virtual Chassis and uplink use. Packet switching capacity is 456 Gbps unidirectional (912 Gbps bidirectional). It is the 550 W DC power supply, AFI (back-to-front airflow) variant, with dual load-sharing hot-swappable PSU bays and no PoE. It runs Junos OS with a base licence and can be managed from the cloud through Juniper Mist Wired Assurance.

An optional extension module adds 4 x SFP+, 4 x SFP28 or 1 x QSFP28 ports (EX4400-EM-4S, EX4400-EM-4Y and EX4400-EM-1C). The 100GbE ports support Virtual Chassis of up to 10 members.

FAQs

Q: Does this switch provide PoE?
A: No. This model has no PoE ports. It is a fibre access switch with SFP and SFP+ ports.

Q: What power does the EX4400-48F-DC-AFI use?
A: It uses a 550 W DC power supply with a 48-60 V input range. There are two PSU bays with load sharing, and one PSU is enough for a fully loaded chassis.

Q: What does AFI airflow mean?
A: AFI is back-to-front airflow, so air enters at the power supply and fan side and exits at the port side. Choose it when your rack cooling layout requires that direction.

Q: Can I add more ports?
A: Yes. The optional extension modules EX4400-EM-4S (4 x SFP+), EX4400-EM-4Y (4 x SFP28) and EX4400-EM-1C (1 x QSFP28) fit this switch.

Q: How do I stack or uplink this switch?
A: The two 100GbE QSFP28 ports are used for Virtual Chassis of up to 10 members or as uplinks. DAC cables and optics are ordered separately.
