48-Port Gigabit Switch

The Juniper EX4200-48T-DC delivers 48 ports of 10/100/1000Base-T connectivity for rackmount deployments. It suits network administrators building managed access layers in enterprise or campus environments. A 190W DC power supply is included for direct current infrastructure. The unit ships with a 50cm Virtual Chassis cable for stacking.

Rackmount Build with SFP Uplinks

The 1U rackmount chassis fits standard cabinets and provides four dedicated SFP uplink interfaces for fibre or copper transceivers. Four additional Gigabit Ethernet expansion slots allow future port density growth. Front-to-rear airflow matches typical data centre cooling designs. DC power input simplifies installation in telecom or industrial facilities using -48V busbars.

Check DC Power and Stacking Needs

Verify your site provides -48V DC power feeds with adequate amperage for the 190W supply. Confirm that SFP transceivers match the required fibre type and reach for uplink connections. Ensure rack space and cable management allow for the 50cm Virtual Chassis cable when stacking multiple units. The switch requires Junos OS licensing for advanced Layer 3 features.

Questions about this item

What does the SFP uplink interface limit in practice?

The four SFP uplink ports accept 1 Gbps transceivers, so each uplink caps at 1 Gbps full-duplex regardless of the SFP module used.

What rack space and cabling does the 48-port DC model require?

It mounts in a standard 19-inch rack and ships with a 50 cm virtual-chassis cable for stacking; DC power leads must reach the 190 W supply terminals.

How is the switch initially configured, and which step is often missed?

Connect the console cable, run the JunOS setup wizard to assign an IP address, then commit the configuration — forgetting to commit leaves the switch unreachable after reboot.
