Description

The Juniper EX4400 is a fixed 1U fibre access and aggregation switch for enterprise campus, branch and data centre networks. This DC-powered model suits telecom and remote sites where DC feeds are standard, and it also fits EVPN-VXLAN campus fabric deployments.

There are 36 x 100/1000BASE-X SFP ports and 12 x 1/10GbE SFP+ ports, plus 2 x 100GbE QSFP28 uplink/Virtual Chassis ports. It has no PoE. Switching capacity is 456 Gbps unidirectional (912 Gbps bidirectional) with 678 Mpps of Layer 2/3 throughput. Power comes from a 550 W DC supply (48-60 V DC input) with front-to-back (AFO) airflow, and the chassis has dual load-sharing hot-swappable PSU bays, with a single PSU sufficient for a fully loaded unit.

Up to 10 EX4400 units can be joined over a 400 Gbps Virtual Chassis interconnect and managed as one logical device. An optional 4-port 1/10GbE or 10/25GbE extension module is available separately, and MACsec AES-256 is supported with the appropriate licence.

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

FAQs

Q: Does this switch need a licence?
A: It runs Junos OS with the base feature set. MACsec AES-256 requires a separately sold licence, and advanced Layer 3 and EVPN-VXLAN features are covered by Juniper software licences.

Q: Does it provide PoE?
A: No. This is a non-PoE model with 0 PoE ports, so it suits fibre access and aggregation rather than powering endpoints.

Q: What power does it need?
A: It uses a 550 W DC power supply with a 48-60 V DC input. The chassis has dual load-sharing hot-swappable PSU bays, and one PSU is enough for a fully loaded unit.

Q: What airflow does this model use?
A: It is the AFO variant with front-to-back airflow, so it should be racked with the port side facing the cold aisle.

Q: Can I add more uplink or 10G ports?
A: Yes. An optional extension module adds 4 x 1/10GbE or 10/25GbE ports, bringing the total to 16 x 10GbE or 4 x 25GbE. The module is sold separately.

Q: Can it be stacked with other EX4400 switches?
A: Yes. The 100GbE ports support a 400 Gbps Virtual Chassis interconnect, joining up to 10 EX4400 units into one logical device.
