EX3200 Switches Hardware Overview

Juniper Networks EX Series Ethernet Switches provide scalable connectivity for the enterprise market, including branch offices, campus locations, and data centers. The switches run the Juniper Networks Junos operating system (Junos OS), which provides Layer 2 and Layer 3 switching, routing, and security services. The same Junos OS code base that runs on EX Series switches also runs on all Juniper Networks M Series, MX Series, and T Series routers.

Power over Ethernet (PoE) Ports on page 4

EX3200 Switches

Juniper Networks EX3200 Ethernet 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. EX3200 switches with a DC power supply installed do not provide 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.

EX3200 Switch Hardware Guide

Uplink Modules

•

Junos OS with its modular design that enables failed system processes to gracefully restart.

EX3200 switches have these features:

•

Run Junos OS for EX Series switches

•

Have options of 24-port and 48-port models

•

Haveoptions of full (all ports) or partial (8 ports) PoweroverEthernet (PoE) capability

•

Have optional uplink modules that provide connection to distribution switches

Optional uplink modules are available for all EX3200 switches. Uplink modules provide two 10-gigabit small form-factor pluggable (XFP) transceivers, four 1-gigabit small form-factor pluggable(SFP) transceivers, or two 10-gigabit small form-factor pluggable (SFP+) transceivers. You can use XFP, SFP, or SFP+ ports to connect an access switch to a distribution switch.

Power over Ethernet (PoE) Ports

PoEports provide electrical current to devices through the network cables so that separate power cords for devices such as IP phones, wireless access points, and security cameras are unnecessary.

PoE is defined in the IEEE 802.3af standard. In this standard, the amount of power that can be supplied to a powered device is limited to 15.4 W. Starting with Junos OS Release

11.1, EX3200 switches support enhanced PoE, a Juniper Networks extension to the IEEE

302.3af PoE standard that permits up to 18.6 W per PoE port.

EX3200 switches with an AC power supply installed have options of full (all 24 or 48 ports) or partial (8 ports) PoE capability. EX3200 switches with a DC power supply installed do not provide PoE.

Full PoE models are primarily used in IP telephony environments. Partial PoE models are used in environments where, for example, only a few ports for wireless access points or security cameras are required.

Field-Replaceable Units in EX3200 Switches

Field-replaceable units (FRUs) are components that you can replace at your site. The FRUs in the switch are:

•

Power supply

•

Fan tray

•

Uplink module

•

Transceivers

NOTE: Uplink modules are not part of the standard package and must be

ordered separately.

Documentation

The fan tray, uplink module, and transceivers are hot-removable and hot-insertable: You can remove and replace them without powering off the switch or disrupting switch functions.

NOTE: If you have a Juniper J-Care service contract, register any addition,

change, or upgrade of hardware components at

https://www.juniper.net/customers/support/tools/updateinstallbase/ . Failure

to do so can result in significant delays if you need replacement parts. This note does not apply if you replace existing components with the same type of component.
