EX4200 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 J Series, M Series,

MX Series, and T Series routers and SRX Series devices.

• Uplink Modules on page 4

• Power over Ethernet Ports on page 4

EX4200 Switches

Juniper Networks EX4200 Ethernet Switches provide connectivity for medium- and

high-density environments and scalability for growing networks. These switches can be

deployed wherever you need 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 andmanage the

unit as a single chassis, called a Virtual Chassis. You can addmore member switches to

the Virtual Chassis as needed, up to a total of 10 members.

EX4200switchesareavailable inmodelswith24or48portswitheitherall portsequipped

for Power over Ethernet (PoE/PoE+) or only 8ports equipped for PoE. Allmodels 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.

Additionally, a 24-port model provides 100Base-FX/1000Base-X SFP ports. This model

is typically used as a small distribution switch.

All EX4200 switches have dedicated 64-Gbps Virtual Chassis ports (VCPs) that allow

you to connect the switches to each other. You can also use optional uplinkmodule ports

to connect members of a Virtual Chassis across multiple wiring closets.

To provide carrier-class reliability, EX4200 switches include:

• Dual redundant power supplies that are field-replaceable and hot-swappable. An

optional additional connection to an external power source is also available.

• A field-replaceable fan tray with three fans. The switch remains operational if a single

fan fails.

• RedundantRoutingEngines inaVirtualChassis configuration. This redundancyenables

graceful Routing Engine switchover (GRES) and nonstop active routing (NSR).

• Junos OSwith its modular design that enables failed system processes to gracefully

restart.

EX4200 switches have these features:

• Run under Junos OS for EX Series switches

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

• Have options of full (all ports) PoE/PoE+ capability or partial (8 ports) PoE capability

• Have optional uplink modules that provide connection to distribution switches

Uplink Modules

Optional uplink modules are available for all EX4200 switches. Uplink modules provide

two ports for installing 10-gigabit small form-factor pluggable (XFP) transceivers, four

ports for installing 1-gigabit small form-factor pluggable (SFP) transceivers, or two ports

for installing 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 or to

interconnect member switches of a Virtual Chassis across multiple wiring closets.

Power over Ethernet Ports

PoEportsprovideelectrical current todevices through thenetworkcables so that separate

power cords for devices such as IP phones, wireless access points, and security cameras

are unnecessary.

PoE was first defined in the IEEE 802.3af standard. Starting with Junos OS Release 11.1,

EX4200 switches support enhanced PoE, a Juniper Networks extension to the IEEE

302.3af PoE standard that increases the amount of power per PoE port. A later standard,

IEEE 802.3at, defined PoE+. An IEEE 802.3af powered device operates normally when

connected to an IEEE 802.3at (PoE+) power sourcing equipment.



EX4200 switches with an AC power supply installed have options of full (all 24 or 48

ports) PoE/PoE+ capability or partial (8 ports) PoE capability. EX4200 switches with a

DC power supply installed do not provide PoE.

Full PoE/PoE+models are primarily used in IP telephony environments. Partial PoE

models are used in environmentswhere, for example, only a fewports forwireless access

points or security cameras are required.

Field-Replaceable Units in EX4200 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

• SFP transceiver

• SFP+ transceiver

• XFP transceiver

NOTE: Uplinkmodules are not part of the standard package andmust beordered separately.

The power supply, fan tray, uplink module, and transceivers are hot-removable and

hot-insertable: You can remove and replace themwithout 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 athttps://www.juniper.net/customers/csc/management/updateinstallbase.jsp.

Failure to do so can result in significant delays if you need replacement parts.This note applies if you change the type of power supply or add a new typeof uplinkmodule. It does not apply if you replace these componentswith thesame type of component.

Chassis Status LEDs in EX4200 Switches

The front panel of an EX4200 switch has three LEDs on the far right side of the panel,

next to the LCD panel (see Figure 6 on page 19).

Figure 6: Chassis Status LEDs in an EX4200 Switch

Table 5 on page 19 describes the chassis status LEDs in an EX4200 switch, their colors

and states, and the status they indicate. You can view the colors of the three LEDs

remotely through the CLI by issuing the operational mode command show chassis lcd.

State and DescriptionColorLED Label

There is no alarm.UnlitALM (Alarm)

There is a major alarm.

NOTE: When you connect power to the switch, the Alarm(ALM) LED lights red. This behavior is normal. Plugging anactive Ethernet cable into the management (MGMT) port onthe switch completes the network link and turns off the ALMLED. (See “Connecting an EX Series Switch to a Network forOut-of-Band Management” on page 154.)

Connecting the switch to a dedicatedmanagement consoleinstead of a network does not affect the ALM LED. The LEDremains red until the switch is connected to a network.

Red

There is a minor alarm.

NOTE: The Alarm (ALM) LED lights amber if you commit aconfiguration to make it active on the switch and do not alsocreate a rescue configuration to back it up. To save themostrecently committed configuration as the rescue configuration,enter the operational mode command request systemconfiguration rescue save.
