Best Fit Applications

DC-Powered Campus Access

Juniper positions the EX3400 as an access-layer switch for campus fabric deployments. With 24 Gigabit Ethernet ports, four SFP/SFP+ uplinks, two 40GbE QSFP+ ports, and a 150W DC power supply, EX3400-24T-DC fits access cabinets that use DC power and require higher-speed uplink options.

Non-PoE Wiring Closet Access

EX3400-24T-DC provides 24 10/100/1000BASE-T access ports without PoE, making it suitable for wired endpoints that have their own power source. Its SFP/SFP+ and QSFP+ interfaces provide uplink capacity for distribution or aggregation connections.

Virtual Chassis Access and Distribution

The EX3400 platform supports up to 10 EX3400 switches in one Virtual Chassis. The two QSFP+ ports are configured as Virtual Chassis ports by default, while SFP+ uplink ports can also be configured as VCPs when the required transceivers and configuration conditions are met.

Why EX3400-24T-DC

Native DC Power Configuration

The model uses a 150W DC power supply, making it a direct hardware choice for network environments built around -48 to -60VDC power systems.

High-Speed Uplink Flexibility

The combination of SFP/SFP+ ports and 40GbE QSFP+ ports provides an upgrade path from Gigabit access connectivity to 10GbE and 40GbE switch interconnection or upstream aggregation.

Virtual Chassis Expansion

Up to 10 EX3400 switches can operate as one logical device through Virtual Chassis, simplifying management and enabling multi-switch expansion within the same platform family.

Field-Replaceable Power and Cooling

The EX3400 supports hot-removable and hot-insertable power supplies and fan modules. EX3400-24T-DC uses front-to-back airflow and EX3400-FAN-AFO fan modules.
