Description

The Juniper EX4200-48PX is a 1 RU, 48-port Gigabit Ethernet access switch from the EX4200 series. Every port supplies 802.3at PoE+, making it a strong fit for branch, campus and data centre access deployments with dense IP telephony, IP cameras and 802.11n wireless access points. It runs Junos OS and supports Virtual Chassis, so a site can start with one switch and grow by adding units.

The 48 10/100/1000BASE-T RJ-45 ports can each deliver up to 30 W, drawn from a 740 W PoE budget supplied by the 930 W AC power supply (autosensing 100-120 V / 200-240 V). Packet switching capacity is 136 Gbps with 101 Mpps wire-speed throughput, and the 128 Gbps Virtual Chassis backplane lets up to 10 EX4200 members operate as one logical device. The base Junos software licence provides full Layer 2 plus IPv4 and IPv6 Layer 3 routing, including RIP, OSPF, PIM and static routing.

Uplinks are added through optional modules: 4 x GbE SFP, 2 x 10GbE XFP, or the dual-mode 2 x 10GbE SFP+ / 4 x GbE SFP module. A MACsec uplink module variant is also available.

Enquire with XS Network Tech for new or used pricing and availability.

FAQs

Q: Does this switch need a separate licence for Layer 3 routing?
A: No. The base Junos licence provides full Layer 2 plus IPv4 and IPv6 Layer 3 routing, including RIP, OSPF, PIM and static routing. Advanced features such as BGP and IS-IS need the optional Advanced Feature License, and MACsec needs its own software licence.

Q: How much PoE can it supply?
A: All 48 ports support 802.3at PoE+ at up to 30 W each, drawn from a 740 W total PoE budget. Not every port can run at 30 W at once, as the budget is shared across the ports.

Q: What power supply does it use?
A: It uses a 930 W AC power supply with autosensing 100-120 V / 200-240 V input. A second power supply can be fitted for load-sharing redundancy.

Q: Which uplink modules and optics does it work with?
A: Uplink modules are EX-UM-4SFP (4 x GbE SFP), EX-UM-2XFP (2 x 10GbE XFP) and EX-UM-2X4SFP (dual-mode 2 x 10GbE SFP+ / 4 x GbE SFP), plus a MACsec variant. These accept 100BASE-FX/LX/BX and 1000BASE-T/SX/LX/LH/ZX/BX SFP optics, 10GbE XFP and 10GbE SFP+ optics.

Q: How many switches can be joined in a Virtual Chassis?
A: Up to 10 EX4200 units can be interconnected over the 128 Gbps Virtual Chassis backplane and managed as a single device. EX4200 switches can also be combined with EX4500 switches in the same Virtual Chassis.
