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.

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.

Complete Hardware Guide for EX4200 Ethernet Switches
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.

LCD Panel Modes
The LCD panel operates in four modes: boot, idle, status, andmaintenance.
The LCD panel operates in bootmode during switch reboot. The bootmode displays the
key milestones in the switch boot process. The boot mode does not have any menu
options. After the boot process is complete, the LCD panel automatically reverts to the
Idle menu.
In an EX4200 switch that is not a member of a Virtual Chassis, the first line of the LCD
panel displays the slot number, the role of the switch, and hostname. For a standalone
EX4200 switch, the slot number is always 00 and the role is always RE (for master).
In an EX4200 switch that is amember of a Virtual Chassis, the first line of the LCD panel
displays:
• The slot number (the member ID for the Virtual Chassis member)
• Role of the switch in aVirtual Chassis (RE formaster,BK for backup, and LC for linecard
member)
• Hostname
In the idlemode, the second line displays themode of the network ports’ Status LED and
the number of chassis alarms. The number of alarms is updated every second.
In the status mode, the second line displays:
• Virtual Chassis port (VCP) status (for an EX4200 switch that is amember of a Virtual
Chassis)
• Status of the power supply

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.

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.
Table 5: Chassis Status LEDs in an EX4200 Switch
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.
