EX4600 Switch Hardware Overview

The Juniper Networks EX4600 Ethernet switch is a highly versatile, second generation solution for campus environments. The EX4600 can be deployed in these environments:

  • Campus distribution
  • Small campus core
  • Top-of-rack in small, low -density data centers
  • Data center distribution in small, low -density data centers

In addition to operating as a standalone switch, the EX4600 switch can act as a member switch in a non-mixed Virtual Chassis, a Virtual Chassis composed entirely of EX4600 switches, as well as participate as member switches in a mixed Virtual Chassis with EX4300 switches. The switch offers a flexible configuration of high-performance 10-gigabit and 40-gigabit ports to add higher port densities, additional scalability, and improved latency to the EX Series of switches.

EX4600 Hardware

The EX4600 switch is a compact 1 U model that provides wire-speed packet performance, very low latency, and a rich set of Layer 2 and Layer 3 features. In addition to a high-throughput Packet Forwarding Engine, the performance of the control plane running on the EX4600 model is enhanced by the 1.5 -GHz dual-core Intel CPU with 8 GB of memory and 32 GB of solid-state drive (SSD) storage.

The port panel of the EX4600 features 24 fixed small form-factor pluggable (SFP) or SFP+ access ports and 4 fixed quad SFP+ (QSFP+) high-speed uplinks.

In addition, the switch has two module bays where you can install optional expansion modules. The EX4600 switch supports two expansion modules to increase port density:

  • QFX-EM-4Q–Adds four additional QSFP+ ports to the chassis. When fully populated with QFX-EM-4Q expansion modules, the EX4600 is equivalent to one with 72 interfaces (24 + 16 + 16 + 16). See Figure 2.

  • EX4600-EM-8F–Adds a total of eight additional SFP+ ports to the chassis. When fully populated with EX4600-EM-8F expansion modules, the EX4600 is equivalent to one with 56 interfaces (24 + 16 + 8 + 8). See Figure 3.

The EX4600 switch can be used as:

  • A standalone switch.
  • A master, backup, or linecard member in a Virtual Chassis with EX4600 switches or EX4300 switches. When in a mixed Virtual Chassis consisting of EX4600 switches and EX4300 switches, the EX4600 switches can be the master, backup, or in the linecard role, while the EX4300 switches must be in the linecard role. An EX4600 Virtual Chassis enables you to interconnect up to 10 switches into one logical device and manage the device as a single chassis. An EX4600 Virtual Chassis is cabled in a ring topology.

    In a mixed Virtual Chassis of EX4600 and EX4300 switches, the Junos OS release dictates whether the EX4600 is best used in the master role. For Junos OS releases between 13.2X50-D10 and 14.1X53-D25, use the use the EX4300 as a master and backup RE in the Virtual Chassis. For Junos OS Release 14.1X53-D25 and later, the EX4600 is fully supported as the master in a mixed Virtual Chassis of EX4600 and EX4300.

System Software

EX Series switches run the Junos operating system (OS), which provides Layer 2 and Layer 3 switching, routing, and security services. An EX4600 switch ships with Junos OS installed on it. The same Junos OS code base that runs on EX4600 switches also runs on all Juniper Networks QFX Series devices, M Series, MX Series, and T Series routers.

You manage the switch by using the Junos OS CL), which is accessible through the console and out-of-band management ports on the switch.

All models of the EX4600 run on Junos OS Release 13.2X51-D25 or later.
