Description

The EX4400-24T is a cloud-ready 1U access switch from the Juniper EX4400 line, driven by Mist AI. This SKU is the spare chassis, supplied without power supplies or fan modules, making it suited to replacing or expanding EX4400-24T access switches in campus, branch and data centre top-of-rack deployments, including EVPN-VXLAN campus fabrics and Virtual Chassis builds.

It provides 24 x 10/100/1000BASE-T RJ-45 non-PoE ports and 2 x 100GbE QSFP28 ports that serve as uplinks or Virtual Chassis interconnects. Packet-switching capacity is 324 Gbps unidirectional and 648 Gbps bidirectional, with 333 Mpps throughput and a 400 Gbps Virtual Chassis backplane. Up to 10 members can be joined in a Virtual Chassis. An optional 4 x 10G or 4 x 25G uplink module is available separately. This is a non-PoE model, so there is no PoE budget.

The switch runs Junos OS with the base feature set. MACsec AES-256 encryption requires an optional licence, and cloud management through Juniper Mist Wired Assurance is subscription-based. To operate, the chassis needs separately ordered EX4400 power supplies (550 W AC in AFO or AFI airflow, or 550 W DC) and fan modules.

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 encryption needs an optional licence sold separately, and Juniper Mist Wired Assurance cloud management is subscription-based.

Q: What power supplies and fans does it need?
A: The chassis needs separately ordered EX4400 power supplies and fan modules to operate. The EX4400-24T uses a 550 W AC power supply (AFO or AFI airflow) or a 550 W DC power supply (48-60 V). It has dual load-sharing hot-swappable PSU slots, and one PSU is the minimum for a fully loaded chassis.

Q: Does it support PoE?
A: No. The EX4400-24T is a non-PoE model, so it has no PoE budget. Connected devices must be powered separately.

Q: What can the 100G QSFP28 ports be used for?
A: They work as uplinks or as Virtual Chassis ports. A DAC for Virtual Chassis is ordered separately, and up to 10 members can be joined.

Q: Can I add 10G or 25G uplinks?
A: Yes. An optional 4 x 10G or 4 x 25G uplink module is available separately for the EX4400 line.
