EX2200 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 and SRX Series Services Gateways.

Juniper Networks EX2200 Ethernet Switches provide connectivity for low-density environments.

EX2200 Switches First View

EX2200 switches are available in models with 12 , 24, or 48 built-in network ports. The compact, fanless model, EX2200-C switches have 12 network ports.

Page 24

EX2200 and EX2200-C Switches Hardware Guide

EX2200 switches provide:

•

Up to four uplink ports

•

12 (compact, fanless model), 24, or 48 built-in networkports with 10/100/1000BASE-T Gigabit Ethernet connectors

•

Virtual Chassis capability—Starting with Junos OS Release 12.2, you can connect up to four EX2200 switches (including EX2200-C switches) together to form one unit that you manage as a single chassis, called a Virtual Chassis. For information about understanding and configuring Virtual Chassis, see Virtual Chassis Feature Guide for EX2200, EX3300, EX4200, EX4500 and EX4550 Switches.

•

Power over Ethernet (PoE or PoE+) on all network ports (in PoE-capable models)

Uplink Ports

Each EX2200 switch except the EX2200-C switch model has four uplink ports that support 1-gigabit small form-factor pluggable (SFP) transceivers for use with fiber connections and copper connections.

Console Port

Each EX2200-C switch has two dual-purpose uplink ports. Each dual uplink port consists of an RJ-45 port (in which you can connect a copper Ethernet cable) and an SFP port (into which you can plug a transceiver). Only one of the ports can be active at a time. By default, if you connect a copper Ethernet cable to the RJ-45 port, this port becomes the active port provided that there is no connection made on the other port. If you plug a transceiver into the SFP port, this port becomes the active port whether or not a copper Ethernet cable is connected to the other port. You can change this default behavior by explicitly configuring a media type—copper or fiber—for the dual-purpose port by using the media-type command. For more information, see Configuring the Media Type on Dual-Purpose Uplink Ports (CLI Procedure).

You can use an SFP uplink port connection between EX2200 switches to interconnect the switches into an EX2200 Virtual Chassis. For this, you must explicitly configure an SFP port each on the switches to be connected as a VCP. See Setting an Uplink Port on an EX Series Switch as a Virtual Chassis Port (CLI Procedure).

For information about the supported optical and copper interfaces, see “Pluggable

Transceivers Supported on EX2200 Switches” on page 67.

Each EX2200 switch exceptthe EX2200-C switch model has an RJ-45console port that accepts a cable with RJ-45 connector.

The EX2200-C switch has two console ports: an RJ-45 port and a Mini-USB Type-B port. The RJ-45 console port accepts a cable with an RJ-45 connector and the Mini-USB Type-B console port accepts a Mini-B plug (5-pin) connector to connect to the console management device. The switch activates only one console port at a time, either the RJ-45 console port or the Mini USB type-B console port. By default, the RJ-45 port is the active console port and the Mini-USB Type-B port is the passive console port. You can change the default setting of a console port by using the port-type command. See Configuring the Console Port Type (CLI Procedure).

Page 25

Cable Guard

On an EX2200-C switch model, you can install a cable guard to secure the cables connected to the switch. The cable guard has slots in the front of it through which you can pass all the cables to prevent them from being accidently unplugged or removed after they are connected. See “Mounting an EX2200 Switch on a Desk or Other Level

Surface” on page 92.

Security Slots

Each EX2200-C switch model has security slots on the left and right panels of the chassis. Use the security slots tolock and secure the chassis in the installationsite with a standard cable lock . See “Mounting an EX2200 Switch on a Desk or Other Level Surface” on

page 92.

Power over Ethernet (PoE) Ports

EX2200 switches are available in models with or without PoE/PoE+ capability. Models that support PoE/PoE+ provide that support on all network ports. PoE ports provide electrical current to devices—such as IP phones, wireless access points, and security cameras—through network cables, thus eliminating the need for separate power cords for those devices.

Chapter 1: System Overview

EX2200 switches with DC power supply do not provide PoE.

NOTE: Starting with Junos OS Release 12.2R1, PoE commands are enabled

on all non-PoE-capable EX2200 switch models. The PoE commands do not provide any meaningful information on standalone non-PoE-capable switch models. However, in an EX2200 Virtual Chassis, you can execute PoE commands from a non-PoE-capable switch that is the master, to configure PoE on PoE-capable Virtual Chassis members.

PoE-capable EX2200 switches running Junos OS Release 10.3 or later support powered devices that comply with IEEE 802.3af (PoE) and IEEE 802.3at (PoE+).

NOTE: IEEE 802.3at class 4 powered devices require category 5 or higher

Ethernet cables.

EX2200 switches running Junos OS Release 10.2 or earlier support powered devices that comply with IEEE 802.3af (PoE).

The remainder of this topicuses the term PoE to refer to both PoE and PoE+ unless there is a need to distinguish between the two.

Cooling System and Airflow in an EX2200 Switch on page 19

Cooling System and Airflow in an EX2200 Switch

Thecooling system in EX2200 switches,exceptEX2200-C, the compact, fanless models, consists of two fans along the rear of the chassis that provide side-to-rearchassis cooling. In the PoE models of these switches, there is an additional fan in the power supply.

In the EX2200-C switch the cooling is done by the vents on top and sides of the chassis in non-PoE models and by heatsinks in PoE+ models. Do not block the vents on the chassis. Doing this can lead to overheating of the switch chassis

Documentation

Under normal operating conditions, the fans operate at a moderate speed to reduce noise. Temperature sensors in the chassis monitor the temperature within the chassis. If any fan fails or if the temperature inside the chassis rises above the threshold, the switch raises an alarm and all functioning fans operate at a higher speed than normal. If the temperature inside the chassis rises above the threshold, the switch shuts down automatically.

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.

Page 69

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 29 on page 49 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.

•

Requirements for Mounting an EX2200 Switch on a Desktop or Wall

You can install the switch on or under a desk or other level surface or on a wall. When choosing a location, allow at least 6 in. (15.2 cm) of clearance between the front and back of the chassis and adjacent equipment or walls.

Ensure that the wall onto which the switch is installed is stable and securely supported.

If you are mounting the switch in sheetrock (wall board with a gypsum plaster core) or in wall board not backed by wall studs, use hollow wall anchors capable of supporting the combined weight of two fully loaded chassis. Insert the screws into wall studs wherever possible to provide added support for the chassis.

Use the wall-mount kit from Juniper Networks to mount the switch on a wall. The wall-mount kit is not part of the standard package and must be ordered separately.

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, even though 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. Determine values forthe 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

) 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 power margin (PM) greater than zero indicatesthat the power budget is sufficient to operate the receiver and that it does not exceed the maximum receiver input power.

Page 85

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 64.

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 37 on page 65 (here, the link is 2 km long and multimode, and the (PB) is 13 dBm):

Understanding EX Series Switches Fiber-Optic Cable Signal Loss, Attenuation, and Dispersion

To determine the power budget and power margin needed for fiber-optic connections, you need to understand how signal loss, attenuation, and dispersion affect transmission. EX Series Switches use various types of network cable, including multimode and single-mode fiber-optic cable.

•

Signal Loss in Multimode and Single-Mode Fiber-Optic Cable on page 70

•

Attenuation and Dispersion in Fiber-Optic Cable on page 70

Signal Loss in Multimode and Single-Mode Fiber-Optic Cable

Multimode fiber is large enough in diameter to allow rays of light to reflect internally (bounce off the walls of the fiber). Interfaces with multimode optics typically use LEDs as light sources. However, LEDs are not coherent light sources. They spray varying wavelengths of light into the multimode fiber, which reflects the light at different angles. Light rays travel in jagged lines through a multimode fiber, causing signal dispersion. When light traveling in the fiber core radiates into the fiber cladding (layers of lower refractive index material in close contact with a core material of higher refractive index), higher-order mode loss (HOL) occurs. Together, these factors reduce the transmission distance of multimode fiber compared to that of single-mode fiber.

Single-mode fiber is so small in diameter that rays of light reflect internally through one layeronly. Interfaces with single-mode optics use lasers as light sources. Lasers generate a single wavelength of light, which travels in a straight line through the single-mode fiber. Compared to multimode fiber, single-mode fiber has a higher bandwidth and can carry signals for longer distances. It is consequently more expensive.

Exceedingthe maximum transmission distancescan result in significant signal loss, which causesunreliable transmission. For information about the maximum transmission distance and supported wavelength range forthe types of single-mode and multimode fiber-optic cables that are used on different EX Series switches see “Pluggable Transceivers

Supported on EX Series Switches” on page 68.

Attenuation and Dispersion in Fiber-Optic Cable

An optical data link functions correctlyprovidedthat modulated light reaching the receiver has enough power to be demodulated correctly. Attenuation is the reduction in strength of the light signal during transmission. Passive media components such as cables, cable splices, and connectors cause attenuation. Although attenuation is significantly lower for optical fiber than for other media, it still occurs in both multimode and single-mode transmission. An efficient optical data link must transmit enough light to overcome attenuation.

Dispersion is the spreading of the signal over time. The following two types of dispersion can affect signal transmission through an optical data link:

•

Chromatic dispersion, which is the spreading of the signal over time caused by the different speeds of light rays.

Page 91

Chapter 8: Transceiver and Cable Specifications

•

Modal dispersion, which is the spreading of the signal over time caused by the different propagation modes in the fiber.

For multimode transmission, modal dispersion, rather than chromatic dispersion or attenuation, usually limits the maximum bit rate and link length. For single-mode transmission, modal dispersion is not a factor. However, at higher bit ratesand overlonger distances, chromatic dispersion limits the maximum link length.

An efficient optical data link must have enough light to exceed the minimum power that the receiver requires to operate within its specifications. In addition, the total dispersion must be within the limits specified for the type of link in Telcordia Technologies document GR-253-CORE (Section 4.3) and International Telecommunications Union (ITU) document G.957.

When chromatic dispersion is at the maximum allowed, its effect can be considered as a power penalty in the power budget. The optical power budget must allow for the sum of component attenuation, power penalties (including those from dispersion), and a safety margin for unexpected losses.

Console Port Connector Pinout Information

The console port on a Juniper Networks device is an RS-232 serial interface that uses an RJ-45 connector to connect to a console management device. The default baud rate for the console port is 9600 baud.

Table 39 on page 73 provides the pinout information for the RJ-45 console connector.

NOTE: If your laptopor PC does not have a DB-9 male connector pin and you

want to connect your laptop or PC directly to a device, use a combination of the RJ-45 to DB-9 female adapter and a USB to DB-9 male adapter. You must provide the USB to DB-9 male adapter.
