Juniper Networks manual EX3200 Switches, EX4200 Switches

Complete Hardware Guide for EX3200 and EX4200 Ethernet Switches

Typically, EX4200 switches are used in large branch offices, campus wiring closets, and top-of-rack locations in a data center.

Both lines have these features:

■Run under JUNOS Software for EX Series switches

■Have options of 24-port and 48-port models

■Have options of full (all ports) or partial (8 ports) Power over Ethernet (PoE) capability

■Have optional uplink modules that provide connection to distribution switches

EX3200 Switches

EX3200 switches provide connectivity for low-density environments. Typically, you deploy these switches in branch environments or wiring closets where only one switch is required.

EX3200 switches are available in models with either 24 or 48 ports and with either all ports equipped for Power over Ethernet (PoE) or only 8 ports equipped for PoE. All models provide ports that have 10/100/1000Base-T Gigabit Ethernet connectors and optional 1-gigabit small form-factor pluggable (SFP) transceivers, 10-gigabit small form-factor pluggable (SFP+) transceivers, or 10-gigabit small form-factor pluggable (XFP) transceivers for use with fiber connections.

EX3200 switches include:

■A field-replaceable power supply and an optional additional connection to an external power source.

■A field-replaceable fan tray with single fan.

■JUNOS Software with its modular design that enables failed system processes to gracefully restart.

EX4200 Switches

EX4200 switches provide connectivity for medium- and high-density environments and scalability for growing networks. These switches can be deployed wherever you need a high density of Gigabit Ethernet ports (24 to 480 ports) or redundancy.

Typically, EX4200 switches are used in large branch offices, campus wiring closets, and data centers where they can be positioned as the top device in a rack to provide connectivity for all the devices in the rack.

You can connect individual EX4200 switches together to form one unit and manage the unit as a single chassis, called a Virtual Chassis. You can add more member switches to the Virtual Chassis as needed, up to a total of 10 members.

EX4200 switches are available in models with 24 or 48 ports and with either all ports equipped for Power over Ethernet (PoE) or only 8 ports equipped for PoE. All models provide ports that have 10/100/1000Base-T Gigabit Ethernet connectors and optional 1-gigabit small form-factor pluggable (SFP) transceivers, 10-gigabit small form-factor
