Description

The EX4200-48T is a 1 RU, 48-port 10/100/1000BASE-T Layer 2 and Layer 3 access switch from the Juniper EX4200 Series. It suits branch, campus and data centre access, wiring closets and top-of-rack deployments, and the 8 PoE ports can power IP phones, cameras and wireless access points in low-density converged networks.

This -S SKU is the spare chassis variant: 48 RJ45 ports, 8 of which provide 802.3af PoE at 15.4 W per port from a 130 W PoE budget, supplied by a 320 W AC power supply. The datasheet lists it with a 50cm Virtual Chassis cable. Packet switching capacity is 136 Gbps with 101 Mpps wire-speed throughput. Up to 10 units can be joined as one logical device over a 128 Gbps Virtual Chassis backplane.

Base Junos OS includes the full Layer 2 and Layer 3 feature set. The optional EX-48-AFL Advanced Feature License adds IS-IS, BGP and MPLS. The front-panel slot accepts EX-UM-4SFP, EX-UM-2XFP and EX-UM-2X4SFP uplink modules for 1G or 10G fibre connectivity.

FAQs

Q: Does the EX4200-48T-S need a software licence?
A: No. Base Junos OS includes the full Layer 2 and Layer 3 switching feature set. The optional EX-48-AFL Advanced Feature License adds IS-IS, BGP and MPLS, and EX-QFX-MACSEC-ACC is a separate optional MACsec licence.

Q: How much PoE does it provide?
A: PoE is available on the first 8 ports only, using 802.3af at 15.4 W per port. The total PoE budget is 130 W from the 320 W AC power supply.

Q: Which uplink modules does it work with?
A: It accepts EX-UM-4SFP (4 x GbE SFP), EX-UM-2XFP (2 x 10GbE XFP), EX-UM-2X4SFP (2 x 10GbE SFP+ or 4 x GbE SFP) and EX-UM-2X4SFP-M (same with MACsec).

Q: Can it be stacked with other switches?
A: Yes. Up to 10 EX4200 units can be combined in a Virtual Chassis over the 128 Gbps backplane, and EX4200 units can also be combined with EX4500 units.

Q: What does the -S suffix mean?
A: The -S SKU is the spare chassis variant of the EX4200-48T. It is a 48-port switch with 8 PoE ports and a 320 W AC power supply, and the datasheet lists it with a 50cm Virtual Chassis cable.
