Description

The EX4200-48T is a 1RU Layer 2/Layer 3 managed Gigabit Ethernet access switch from the Juniper EX4200 series, running Junos OS. It suits branch, campus and data centre access deployments, wiring closets, top-of-rack use and Gigabit aggregation, with the PoE ports well matched to low-density converged networks carrying IP phones, cameras and wireless access points.

This 48-port variant provides 48 x 10/100/1000BASE-T RJ-45 ports, of which the first 8 deliver 802.3af PoE at 15.4 W per port from a 130 W PoE budget. It is powered by a 320 W AC supply and offers 136 Gbps packet switching capacity, 264 Gbps aggregate switch capacity and 101 Mpps of wire-speed Layer 2/Layer 3 throughput. A front-panel slot accepts optional uplink modules for Gigabit SFP or 10 Gigabit XFP and SFP+ uplinks.

Virtual Chassis technology lets up to 10 EX4200 units be interconnected over a 128 Gbps backplane and managed as a single logical device. The base software includes the full Layer 2 and Layer 3 feature set, while the EX-48-AFL Advanced Feature Licence adds IS-IS, BGP and MPLS.

FAQs

Q: Does the EX4200-48T need a licence to run Layer 3 features?
A: No. The base Junos software includes the full Layer 2 and Layer 3 feature set, including RIP, OSPF, PIM and VRRP. The optional EX-48-AFL Advanced Feature Licence adds IS-IS, BGP and MPLS.

Q: How many ports provide PoE and what is the budget?
A: The first 8 ports provide 802.3af PoE at up to 15.4 W each, from a total PoE budget of 130 W. The remaining 40 ports are standard non-PoE Gigabit ports.

Q: What power supply does this model use?
A: It uses a 320 W AC power supply with autosensing 100-120 V / 200-240 V input. A second power supply can be added for redundancy, and 600 W AC, 930 W AC and 190 W DC supplies are available across the family.

Q: Which uplink modules does it work with?
A: The switch has a front-panel uplink module slot. Supported modules are the EX-UM-4SFP (4-port GbE SFP), EX-UM-2XFP (2-port 10GbE XFP), EX-UM-2X4SFP (2-port 10GbE SFP+ / 4-port GbE SFP) and EX-UM-2X4SFP-M, which adds MACsec.

Q: Can it be stacked or combined with other switches?
A: Yes. Virtual Chassis lets up to 10 EX4200 units be interconnected over a 128 Gbps backplane and managed as a single logical device. Virtual Chassis cables come in 0.5 m, 1 m, 3 m and 5 m lengths (EX-CBL-VCP-xx), and EX4200 units can also be combined with EX4500 switches.
