EX3200 Switches Hardware Overview

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

EX3200 Switches on page 3 Uplink Modules on page 4 Power over Ethernet (PoE) Ports on page 4

EX3200 Switches

Juniper Networks EX3200 Ethernet Switches provide connectivity for low-densityenvironments. Typically, you deploy these switches in branch environments or wiringclosets 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. EX3200switches with a DC power supply installed do not provide PoE. All models provide portsthathave 10/100/1000Base-T Gigabit Ethernet connectors and optional 1-gigabit smallform-factor pluggable(SFP) transceivers,10-gigabit small form-factor pluggable(SFP+)transceivers, or 10-gigabit small form-factor pluggable (XFP) transceivers for use withfiber connections.

EX3200 switches include:



28/254

A field-replaceable power supply and an optional additionalconnection to an externalpower source.

A field-replaceable fan tray with single fan.

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

EX3200 switches have these features:

Run Junos OS for EX Series switches

Have options of 24-port and 48-port models

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

Have optional uplink modules that provide connection to distribution switches

Uplink Modules

Optional uplink modules are available for all EX3200 switches. Uplink modules providetwo 10-gigabit small form-factor pluggable (XFP) transceivers, four 1-gigabit smallform-factor pluggable (SFP)transceivers, or two10-gigabit small form-factor pluggable(SFP+) transceivers. You can use XFP, SFP, or SFP+ ports to connect an access switchto a distribution switch.

Power over Ethernet (PoE) Ports

PoE portsprovide electrical current todevices through thenetworkcablesso that separatepowercords for devices such as IP phones, wireless access points, and security camerasare unnecessary. EX3200 switches with an AC power supply installed have options offull (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 areused in environments where, for example, only a few ports for wireless access points orsecurity cameras are required.

LCD Panel Modes

The LCD panel operates in four modes: boot, idle, status, and maintenance.

TheLCD panel operates in boot mode duringswitch reboot. Theboot mode displays thekey milestones in the switch boot process. The boot mode does not have any menuoptions. After the boot process is complete, the LCD panel automatically reverts to theIdle menu.

In an EX3200 switch, the first line of the LCD panel displays the hostname.

In the idle mode, thesecondline displays themode of thenetwork ports Status LEDandthe number of chassis alarms. The number of alarms is updated every second.

In the status mode, the second line displays:

Field-Replaceable Units in EX3200 Switches

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

Power supply

Fan tray

Uplink module

SFP transceiver

SFP+ transceiver

XFP transceiver

NOTE: Uplink modules are not part of the standard package and must beordered separately.

The power supply, fan tray, uplink module, and transceivers are hot-removable andhot-insertable: You can remove and replace them without powering off the switch ordisrupting 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/csc/management/updateinstallbase.jsp . Failure todo so can resultinsignificant delays if you need replacement parts. This note applies if youchangethe type of power supplyor add a new type of uplink module.

This LED is always on and is meaningful only on EX4200switches.

GreenMST (Master)

A major alarm (red) indicates a critical error condition that requires immediate action.




42/254

A minor alarm (amber) indicates a noncritical condition that requires monitoring ormaintenance. A minor alarm that is left unchecked might cause interruption in service orperformance degradation.

NOTE: The amberglowof theAlarm LEDthatindicates a minoralarmcloselyresembles the redglow that indicates a major alarm.

All three LEDs can be lit simultaneously.

Network Port LEDs in EX3200 Switches

Each network port on the switch has two LEDs. The four figures in this topic show thelocation of those LEDs:

Figure 6 on page 18 shows the location of the LEDs on the network ports on the frontpanel.

Figure 7 on page 19 shows the location of the LEDs on the uplink module ports on theSFP uplink module.

Figure 8 on page 19 shows the location of the LEDs on the uplink module ports on theSFP+ uplink module.

Figure 9 on page 19 shows the location of the LEDs on the uplink module ports on theXFP uplink module.

Table 7: Status LED on Network Ports

State and DescriptionLCD IndicatorLED

Indicates the administrativestatus (enabled or disabled). Thestatus indicators are:

GreenAdministrative status enabled. UnlitAdministrative status disabled.

LED: ADMStatus

Indicates the duplex mode.

The uplink module ports are always setto full-duplex;therefore, the LEDis always green.

The status indicators fornetwork ports on the front panel are:

GreenPort is setto full-duplex mode. UnlitPort is set to half-duplex mode.

LED: DPX

Indicates the PoE status on switcheswith PoE-enabledports.

PoE is not enabled on uplink module ports; therefore, the LEDfor those ports is always unlit.

The status indicators fornetwork ports on the front panel are:

GreenPoE is enabled on the port. AmberPoE is enabled on the port, but no power is drawn

from theport because of one of the following: No device that draws powerfrom the port is connected

to the port. A device that draws power from the port is connected to

the port, but the device is not drawing any power fromthe port.

UnlitPoE is not enabled on theport.

LED: POE

Indicates the speed.LED: SPD

The speed indicators for network ports on the front panel are:

One blink per second10 Mbps Two blinks per second100 Mbps Three blinks per second1000Mbps

The speed indicators for network ports on the SFPuplinkmodule are:

Green1000 Mbps Unlit10/100 Mbps

The speed indicators for network ports on the SFP+ uplinkmodule are:

GreenThe speed of the transceiver installed in the port isthe same asthe speed atwhich the uplink moduleportisconfigured to operate.

UnlitThe speed of the transceiver installed in the port is
