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.

Uplink Modules in EX3200 Switches

EX3200 switches support three types of uplink modules:

•

SFP uplink module—Providesfour ports for 1-gigabit small form-factorpluggable(SFP) transceivers. The model number of the uplink module is EX-UM-4SFP.

NOTE: On an EX3200 switch, if you install a transceiver in an SFP uplink

module, a corresponding network port from the last four built-in ports is disabled. For example, if youinstall an SFP transceiverin port 2 on the uplink module (ge-0/1/2) on 24-port models, then ge-0/0/22 is disabled. Thedisabled port is not listed in the output of the show interface command.

On an EX3200 switch, if you replace a transceiver multiple times in quick succession in a port that uses fiber-optic connectors, the switch might not create an interface for that port and that port might be disabled. For example, if you replacean SFP transceiverin port 2 on the uplink module (ge-0/1/2) multiple times in quick succession, then ge-0/1/2 might be disabled. Thedisabled port is not listed in the output of the show interface command.

Chapter 2: Chassis Components and Descriptions

•

SFP+ uplink module—Provides two ports for 10-gigabit small form-factor pluggable (SFP+) transceivers when configured to operate in 10-gigabit mode or four ports for 1-gigabit small form-factor pluggable (SFP) transceivers when configured to operate in 1-gigabit mode. The model number of the uplink module is EX-UM-2X4SFP.

NOTE: On an EX3200 switch, if you install a transceiver in an SFP+ uplink

module when the uplink module is operating in the 1-gigabit mode, a corresponding network port from the last four built-in ports is disabled. For example, if youinstall an SFP transceiverin port 2 on the uplink module (ge-0/1/2), then ge-0/0/22 is disabled. Thedisabled port is not listed in the output of the show interface command.

•

XFP uplink module—Provides two ports for 10-gigabit small form-factor pluggable (XFP) transceivers.

NOTE: When a new uplink module is installed in the switch or an existing

uplink module is replaced with another uplink module, the switch detects the newlyinstalled uplink module.The switch creates the requiredinterfaces if the uplink module has transceivers in its ports and when new transceivers are installed in uplink module ports.

EX3200 Switch Hardware Guide

SFP Uplink Module

When connecting uplink module ports, you can install an SFP uplink module at one end of the connection and install an SFP+ uplink module configured to operate in the 1-gigabit mode at the other end. Likewise, you can install an XFP uplink module at one end of the connection and install an SFP+ uplink module configured to operate in the 10-gigabit mode at the other end.

Figure 5 on page 16 shows the SFP uplink module, which provides four ports for 1-gigabit

SFP transceivers.

Figure 5: SFP Uplink Module

SFP uplink modules are shipped with dust covers preinstalled in the ports.

The SFP uplink module requires Junos OS for EX Series switches, Release 9.0 or later.

SFP+ Uplink Module and SFP+ MACsec Uplink Module

The SFP+ uplink module and the SFP+ MACsec uplink module can be used for either SFP+ or SFP transceivers. You configure the operating mode on the module to match the type of transceiveryou want to use—for SFP+ transceivers,youconfigure the 10-gigabit operating mode, and for SFP transceivers, you configure the 1-gigabit operating mode. See Setting the Mode on an SFP+ or SFP+ MACSec Uplink Module (CLI Procedure).

By default, the SFP+ uplink module and the SFP+ MACsec uplink module operate in the 10-gigabitmode and support only SFP+ transceivers.If youhave not changed the module from the default setting and you want to use SFP+ transceivers, you do not need to configure the operating mode.

Chapter 2: Chassis Components and Descriptions

If the operating mode and the configured mode for the uplink module are different, it is shown in the output of show chassis pic fpc-slot slot number pic-slot 1.

Figure 6 on page 17 shows the SFP+ uplink module and the SFP+ MACsec uplink module.

Figure 6: SFP+ and SFP+ MACsec Uplink Module

The following transceivers can be installed in the uplink module ports:

•

SFP+ transceivers are supported in ports 0 and 2.

•

SFP transceivers are supported in all four ports.

The ports that support SFP+ transceivers are labeled 10 G on the uplink module’s faceplate (see Figure 6 on page 17).

NOTE: When an SFP+ uplink module or an SFP+ MACsec uplink module is

operating in 10-gigabit mode:

•

Only the 10-gigabit ports (ports 0 and 2) are enabled.

•

You can use only SFP+ transceivers in those ports.

When an SFP+ uplink module or an SFP+ MACsecuplink module is operating in 1-gigabit mode:

•

All four ports are enabled.

•

You can use only SFP transceivers in all four ports.

The SFP+ uplink module and the SFP+ MACsec uplink module have an LED on the faceplate (labeled Operating mode LED in Figure 6 on page 17) that indicates the operating mode. If the uplink module is operating in the 10-gigabit mode, the LED is lit. If the uplink module is operating in the 1-gigabit mode, the LED is unlit.

Power Supply in EX3200 Switches

The power supply in EX3200 switches is a field-replaceable unit (FRU) that you can install on the rear panel. The power supply in EX3200 switches is not redundant.

EX3200 switches use power supplies that provides two DC output voltages: 12 V for system and logic power and 48–51 V (or higher, to compensate for voltage drops along the path from the power supplies to the RJ-45 connector) for PoE ports.

NOTE: After powering on an the switch, wait for at least 60 seconds before

powering it off. After powering off the switch, wait for at least 60 seconds before powering it back on.

AC Power Supplies

After the switch is powered on, it can take up to 60 seconds for status indicators—suchasLEDs on the power supply,show chassis commandoutput, and messages on the LCD panel—to indicate that the power supply is functioning normally. Ignore error indicators that appear during the first 60 seconds.

This topic describes:

•

PoE Power Budget and AC Power Supplies on page 31

All the EX4200 switches that are powered by AC power supplies except the EX4200-24F-S and EX4200-48T-S switches are shipped with one AC power supply pre-installed in the rear panel of the switches. EX4200-24F-S and EX4200-48T-S switches are not shipped with pre-installed power supplies; you must order them separately.

EX3200 Switch Hardware Guide

The AC power supply for the switch is available in 320 W, 600 W, and 930 W models (see Figure 16 on page 30 and Figure 17 on page 30). The exterior of the 600 W model is identical in appearance to that of the 930 W model. The 320 W power supply is flush with the chassis. The 600 W power supply and 930 W power supply extend out of the chassis by 2.25 in. The power cord retainer clips extend out of the power supply by 3 in. The number of ports on which PoE is enabled determines the minimum power requirements of different switch models.

All the EX4200 switches that are powered by DC power supplies except the EX4200-24F-S and EX4200-48T-S switches are shipped with one DC power supply pre-installed in the rear panel of the switches. EX4200-24F-S and EX4200-48T-S switches are not shipped with pre-installed power supplies; you must order them separately.

The DC power supply for the switch is available in a 190 W model, with dual input feeds for power resiliency (see Figure 18 on page 31).

Chapter 4: Power Supplies

NOTE: The DC power supply in the switch does not support Power over

Ethernet (PoE); you can use either an external power injector or an AC power supply to supply power to PoE devices that you connect to the switch.

NOTE: The DC power supply in the switch has four terminals labeled A+, B+,

A–, and B– (see Figure 18 on page 31) for connecting DC power source cables labeled positive (+) and negative (–). The DC power supplies are shipped with jumpers from A+ input to B+ input tied together and jumpers from A– input to B– input tied together.

NOTE: The A+ and B+ terminals are referred to as +RTN and A– and B–

terminals are referred to as –48 V in “DC Power Wiring Sequence Warning”

on page 247 and “DC Power Electrical Safety Guidelines for Switches” on page 242.

or Installing a Power Supply in an EX4200 Switch or Removing a Power Supply from an EX4200 Switch carefully.

PoE Power Budget and AC Power Supplies

The PoE power budget for a PoE switch model is determined by the capacity of its power supply. For EX3200 switches, the capacity of the power supply provided with a PoE model is sufficient to supply each PoE-capableport with up to 15.4 W in compliance with the IEEE 802.3af PoE standard. Table 12 on page 32 lists the EX3200 switch PoE models, their power supply ratings, and the associated PoE power budgets.

Starting with Junos OS Release 11.1, EX3200 switches support enhanced PoE, a Juniper Networks extension to the IEEE 302.3af PoE standard. Enhanced PoE permits up to 18.6 W per PoE port. Because the power supply provided with a switch is designed to supply

EX3200 Switch Hardware Guide

a maximum of 15.4 W per PoE port, if you connect a powered device that draws more than 15.4 W, the PoE power budget might not be sufficient to supply a full 15.4 W to the remaining PoE ports.

NOTE: Switches upgraded to Junos OS Release 11.1 from a previous release

requirea separateupgradeof the PoEcontrollersoftware to enable enhanced PoE support.

Environmental Requirements and Specifications for EX Series Switches

The switch must be installed in a rack or cabinet housed in a dry, clean, well-ventilated, and temperature-controlled environment.

Ensure that these environmental guidelines are followed:

•

The site must be as dust-free as possible, because dust can clog air intake vents and filters, reducing the efficiency of the switch cooling system.

•

Maintain ambient airflow for normal switch operation. If the airflow is blocked or restricted, or if the intake air is too warm, the switch might overheat, leading to the switch temperature monitor shutting down the switch to protect the hardware components.

Table 32 on page 59 provides the required environmental conditions for normal switch

operation.

General Site Guidelines

Efficient device operation requires proper site planning and maintenance and proper layout of the equipment, rack or cabinet (if used), and wiring closet.

To plan and create an acceptable operating environment for your device and prevent environmentally caused equipment failures:

•

Keep the area around the chassis free from dust and conductive material, such as metal flakes.

•

Followprescribed airflow guidelines to ensure that the cooling systemfunctions properly and that exhaust from other equipment does not blow into the intake vents of the device.

Chapter 6: Preparation Overview

•

Follow the prescribed electrostatic discharge (ESD) prevention procedures to prevent damaging the equipment. Static discharge can cause components to fail completely or intermittently over time.

•

Install the device in a secure area, so that only authorized personnel can access the device.

If your site experiences any of the following problems, consult experts in electrical surge suppression and shielding:

•

Improperly installed wires cause radio frequency interference (RFI).

•

Damage from lightning strikes occurs when wires exceed recommended distances or pass between buildings.

•

Electromagnetic pulses (EMPs) caused by lightning damage unshielded conductors and electronic devices.

Radio frequency interference

Electromagnetic compatibility

Documentation

To reduce or eliminate RFI from your site wiring, do the following:

•

Use a twisted-pair cable with a good distribution of grounding conductors.

•

If you must exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal when applicable.

If your site is susceptible to problems with electromagnetic compatibility (EMC), particularly from lightning or radio transmitters, seek expert advice.

Some of the problems caused by strong sources of electromagnetic interference (EMI) are:

•

Destruction of the signal drivers and receivers in the device

•

Electrical hazards as a result of power surges conducted over the lines into the equipment

Documentation

You can mount the device on a rack that provides bracket holes or hole patterns spaced at 1 U (1.75 in. or 4.45 cm) increments and meets the size and strength requirements to support the weight.

A U is the standard rack unit defined by the Electronics Industry Association.

The holes in the mounting brackets are spaced at 1 U (1.75 in. or 4.45 cm), so that the device can be mounted in any rack that provides holes spaced at that distance.

•

Ensure that the rack complies with the size and strength standards of a 19-in. rack as defined by the Electronics Industry Association.

•

Ensure that the rack rails are spaced widely enough to accommodate the external dimensions of the device chassis. The outer edges of the front-mounting brackets extend the width of the chassis to 19 in. (48.2 cm).

•

The rack must be strong enough to support the weight of the device.

•

Ensure that the spacing of rails and adjacent racks provides for proper clearance around the device and rack.

•

Secure the rack to the building structure.

•

If earthquakes are a possibility in your geographical area, secure the rack to the floor.

•

Secure the rack to the ceiling brackets as well as wall or floor brackets for maximum stability.

Cabinet Requirements

You can mount the device in a cabinet that contains a 19-in. rack.

Cabinet requirements consist of:

•

Cabinet size

•

Clearance requirements

•

Cabinet airflow requirements

Table 35 on page 65 provides the cabinet requirements and specifications.

Table 35: Cabinet Requirements and Specifications

Cabinet Requirement

Cabinet size

Cabinet clearance

Guidelines

•

You can mount the device in a cabinet that contains a 19-in. rack as defined by the Electronics Industry Association.

•

The minimum cabinet size must be able to accommodate the maximum external dimensions of the device.

•

The outer edges of the mounting brackets extend the width of the chassis to 19 in. (48.2 cm).

•

The minimum total clearance inside the cabinet is 30 in. (76.2 cm) between the inside of the front door and the inside of the rear door.

Chapter 6: Preparation Overview

Cabinet airflow requirements

When you mount the device in a cabinet, ensure that ventilation through the cabinet is sufficient to prevent overheating.

•

Ensure adequate cool air supply to dissipate the thermal output of the device or devices.

•

Ensure that the hot air exhaust of the chassis exits the cabinet without recirculating into the device. An open cabinet (without a top or doors) that employs hot air exhaust extraction from the top ensures the best airflow through the chassis. If the cabinet contains a top or doors, perforations in these elements assist with removing the hot air exhaust.

•

Install the device in the cabinet in a way that maximizes the open space on the side of the chassis that has the hot air exhaust.

•

Route and dress all cables to minimize the blockage of airflow to and from the chassis.

•

Ensure that the spacing of rails and adjacent cabinets is such that there is proper clearance around the device and cabinet.

•

A cabinet larger than the minimum required provides better airflow and reduces the chance of overheating.

Calculating the EX Series Switch Fiber-Optic Cable Power Budget

Calculate the link's power budget when planning fiber-optic cable layout and distances to ensure that fiber-optic connections have sufficient power for correct operation. The powerbudget is the maximum amount of power the link can transmit.When you calculate the power budget, you use a worst-case analysis to provide a margin of error,eventhough all the parts of an actual system do not operate at the worst-case levels.

To calculate the worst-case estimate for fiber-optic cable power budget (PB) for the link:

1. Determinevalues for the link's minimum transmitter power (P

sensitivity (PR). For example, here, (PT) and (PR) are measured in decibels, and decibels are referred to one milliwatt (dBm).

PT= –15 dBm

PR= –28 dBm

NOTE: See the specifications for your transmitter and receiver to find the

minimum transmitter power and minimum receiver sensitivity.

2. Calculate the power budget (P

) by subtracting (PR) from (PT):

–15 dBm – (–28 dBm) = 13 dBm

Calculating the EX Series Switch Fiber-Optic Cable Power Margin

) and minimum receiver

Calculate the link's power margin when planning fiber-optic cable layout and distances to ensure that fiber-optic connections have sufficient signal power to overcome system losses and still satisfy the minimum input requirements of the receiver for the required performance level. The power margin (PM) is the amount of power available after attenuation or link loss (LL) has been subtracted from the power budget (PB).

When you calculate the power margin, you use a worst-case analysis to provide a margin of error, even though all the parts of an actual system do not operate at worst-case levels.A powermargin (PM) greater than zero indicatesthat the power budgetis sufficient to operate the receiver and that it does not exceed the maximum receiver input power.

This means the link will work. A (PM) that is zero or negative indicates insufficient power to operate the receiver. See the specification for your receiver to find the maximum receiver input power.

Before you begin to calculate the power margin:

•

Calculate the power budget. See “Calculating the EX Series Switch Fiber-Optic Cable

Power Budget” on page 72.

To calculate the worst-case estimate for the power margin (PM) for the link:

1. Determine the maximum value for link loss (LL) by adding estimated values for

applicable link-loss factors—for example, use the sample values for various factors as provided in Table 39 on page 73 (here, the link is 2 km long and multimode, and the (PB) is 13 dBm):

Thisexampleassumes 2 splices. Lossfor two splices:

(2) * (0.5 dBm) = 1 dBm

This example assumes the link is 2 km long. Fiber attenuation for 2 km:

•

(2 km) * (1.0 dBm/km) = 2 dBm

•

(2 km) * (0.5 dBm/km) = 1 dBm

1 dBm1 dBmClock Recovery Module (CRM)

NOTE: For information about the actual amount of signal loss caused by

equipment and other factors, see your vendor documentation for that equipment.

2. Calculate the (P

) by subtracting (LL) from (PB):

EX3200 Switch Hardware Guide

Documentation

PB– LL = P

(13 dBm) – (0.5 dBm [HOL]) – ((5) * (0.5 dBm)) – ((2) * (0.5 dBm)) – ((2 km) * (1.0 dBm/km)) – (1 dB [CRM]) = P

13 dBm – 0.5 dBm – 2.5 dBm – 1 dBm – 2 dBm – 1 dBm = P

PM= 6 dBm

The calculatedpower margin is greaterthan zero,indicating that the link has sufficient power for transmission. Also, the power margin value does not exceed the maximum receiver input power. Refer to the specification for your receiver to find the maximum receiver input power.
