Description

The EX4200 is a 1 RU, 48-port Gigabit access switch built around Juniper Virtual Chassis technology and Junos OS. This DC-powered variant is aimed at branch, campus and data centre access, Gigabit Ethernet aggregation and wiring closets where space and power are tight. NEBS certification also suits telco and central-office environments.

The EX4200-48T-DC provides 48 x 10/100/1000BASE-T RJ-45 access ports with no PoE. It is powered by a 190 W DC supply (36 to 72 V DC, dual input feed) with dual load-sharing, hot-swappable internal redundant power supplies, and one supply is the minimum for a fully loaded chassis. The 128 Gbps Virtual Chassis backplane joins up to 10 units as one logical switch, with 136 Gbps of packet switching capacity, 264 Gbps aggregate capacity and 101 Mpps of wire-speed Layer 2/Layer 3 throughput. The base Junos licence includes Layer 2 and Layer 3 features with RIP and OSPF, and the optional EX-48-AFL Advanced Feature License adds IS-IS, BGP and MPLS.

Optional front-panel uplink modules add GbE or 10GbE connectivity: EX-UM-4SFP, EX-UM-2XFP, EX-UM-2X4SFP and the MACsec-capable EX-UM-2X4SFP-M. It can be combined in a Virtual Chassis with other EX4200 units and with EX4500 switches.

FAQs

Q: Does the EX4200-48T-DC support PoE?
A: No. This variant has 48 non-PoE Gigabit ports and no PoE budget. The PoE model in this range is the EX4200-48P.

Q: What power input does it need?
A: It uses a 190 W DC power supply (EX-PWR-190-DC) with a 36 to 72 V DC input and a dual input feed. One supply is the minimum for a fully loaded chassis, and a second can be fitted for redundancy.

Q: Which licence does it need for BGP, IS-IS or MPLS?
A: The base Junos software includes Layer 2 and Layer 3 features with RIP and OSPF. The optional EX-48-AFL Advanced Feature License adds IS-IS, BGP and MPLS.

Q: Which uplink modules does it work with?
A: It accepts the EX-UM-4SFP, EX-UM-2XFP, EX-UM-2X4SFP and EX-UM-2X4SFP-M uplink modules, which give GbE SFP or 10GbE XFP and SFP+ uplinks.

Q: Can it be stacked with other switches?
A: Yes. Virtual Chassis lets up to 10 units operate as one logical switch over the 128 Gbps backplane. It can be combined with other EX4200 units and with EX4500 switches.
