Why buy it?

The Juniper Networks EX4300-48P is a member of the EX4300 virtual chassis switch series. A step up from the EX3300, this is a top-end, managed Power over Ethernet Plus (PoE+), stack-able, network switch with advanced routing features. It is designed to run in a rack and can operate as an access or distribution layer device, but thrives when collapsing the two topologies together. Advanced functionality in the form of Virtual Chassis, OSPF, BGP and redundant trunk groups means the system is highly fault tolerant. It is a high quality 1U rack mount unit (delivered complete with mounting "ears") with 48 built-in RJ45 PoE+ ports ports and 4 x 40Ge uplink ports (separate purchase QSFP+ optics required).

This great value switch has many of the features of high-end chassis systems, providing the following benefits:

  1. PoE+ delivers up to 30 watts of power per port for devices such as telephones, video cameras or Wireless Access Points
  2. It is managed so you can build segmented networks for better performance and security.
  3. Create resilient systems using Virtual Chassis technology:
    • You can improve resilience by spanning connections to critical servers across multiple chassis members
    • You can grow network capacity without the need to separately manage each unit - thus saving cost
  4. The EX4300-48P supports advanced routing features such as OSPF - to provide resilience between distribution layer devices and the core

The technical stuff

The EX4300-48P has 48 fully configurable PoE/PoE+ Gigabit ethernet ports. These support multiple encapsulations including - L2, L3 VLAN's and (LACP) aggregated interfaces. It is high performance; supporting packet switching capacity at 496Gbs, more than 4000 VLANS, multicast and other advanced network functions. It is also highly secure and supports access control lists (ACL), MAC and other security controls. Together with the dedicated management port, the system can be fully secured.

The EX4300-48P also provides advanced stateless firewall functions. You can specify QoS settings such as bandwidth control and traffic queuing and priority - this means VoIP and other specialised types of traffic can be easily accommodated.

The EX4300-48P supports sFlow & RPM (Real-time response time monitoring) that allows detailed performance monitoring of traffic to ensure that your network is operating at maximum efficiency and, should any occur, problems can quickly be isolated and resolved.

Key Features of the EX4300-48P:

  • 48 fully configurable 10/100/1000Mbs RJ45 Ethernet ports
  • IEEE 802.3af & at standards for up to 30 watts of power per port
  • 4 dual purpose 40Ge ports (at the rear) can be used as uplink or Virtual Chassis connectors. The 40Ge ports require QSFP+ optics (the QSFP 50CM Cable should be used for creating local Virtual Chassis connections).
  • Optional Front uplink module providing 4 x 1Ge or 10Ge SPF uplink ports also configurable as Virtual Chassis connections
  • Up to 10 Virtual Chassis members in an EX4300 cluster
  • Support for 4093 VLAN's
  • IPV4 routing (inc OSPF & RIP)
  • 32,000 routes
  • Up to 1000 802.3ad (LACP) ports (max ports per LAG: 112)
  • Multicast support
  • Quality of Service
  • Dedicated management port
  • Limited lifetime switch hardware warranty


  • Extended Feature License includes support for OSPFv4/v6, PIM-SM/SSM/DM, IGMP v1/v2/v3 and VRF-Lite
  • Advanced Feature License includes support for IS-IS and BGP (EFL needs to be purchased and installed separately before installing AFL)
  • A minimum of 2 licenses must be purchased if operating in a Virtual Chassis mode (one for Master & one for Backup roles)
