EX2300 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 Juniper Networks EX2300 Ethernet Switches run the Juniper Networks Junos operating system (Junos OS), which provides Layer 2 and Layer 3 switching, routing, and security services.

EX2300 switches provide connectivity for low-density environments.

EX2300 Switches First View

EX2300 switches are available in models with 12 or 24, or 48 built-in network ports that support RJ-45 cableconnectors.The compact, fanlessEX2300-C switches have12 RJ-45 network ports.

Page 26

EX2300-C and EX2300 Switches Hardware Guide

EX2300 switches provide:

•

Up to four 10-Gigabit Ethernet uplink ports that support small form-factor pluggable plus (SFP+) transceivers and small form-factor pluggable (SFP) transceivers.

•

12 (in EX2300-C switches), 24, or 48built-in Gigabit Ethernet RJ-45 network ports with 10/100/1000 BASE-T connectors.

•

Virtual Chassis capability—You can connect up to four EX2300 switches (including EX2300-C switches) to form one unit that you manage as a single chassis, called a Virtual Chassis.

•

Power over Ethernet (PoE) or Power over Ethernet Plus (PoE+) on all RJ-45 network ports (in PoE-capable models).

Uplink Ports

EX2300-C switches have two 10-Gigabit Ethernet uplink ports that support SFP and SFP+ transceivers. EX2300 switches except the EX2300-C switch model have four 10-Gigabit Ethernet uplink ports that support SFP and SFP+ transceivers. You can use these uplink ports as network ports or configure these ports as Virtual Chassis ports (VCPs) and use them to connect up to four switches by using SFP+ transceivers to form a Virtual Chassis.

Console Ports

Cable Guard

NOTE: You cannot form a Virtual Chassis by using SFP transceivers.

For forming a Virtual Chassis, you must explicitly configure an uplink port on each of 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 EX2300 Switches” on page 73.

EX2300 switches havetwo console ports—an RJ-45 consoleport and a Mini-USB Type-B console port. The RJ-45 port accepts a cable that has an RJ-45 connector and the Mini-USB Type-B port accepts a Mini-B plug (5-pin) connector to connect the switch to a 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).

On an EX2300-C switch, 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 EX2300 Switch on a Desk or Other Level Surface” on

page 129, “Mounting an EX2300-C Switch Under a Desk or Other Level Surface by Using

Page 27

Screws” on page 131, and “Mounting an EX2300-C Switch on or Under a Surface Made of Ferrous Material” on page 149.

Security Slot

An EX2300-C switch has a security slot on the right panel of the chassis. You can use the security slot to lock and secure the chassis in the installation site with a standard cable lock. See “Mounting an EX2300 Switch on a Desk or Other Level Surface” on

page 129, “Mounting an EX2300-C Switch Under a Desk or Other Level Surface by Using Screws” on page 131, and “Mounting an EX2300-C Switch on or Under a Surface Made of Ferrous Material” on page 149.

Power over Ethernet (PoE) Ports

EX2300 switches areavailablewith or without PoE/PoE+capability.Models that support PoE/PoE+ provide that support on all RJ-45 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. Uplink ports do not support PoE.

Chapter 1: System Overview

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

Ethernet cables.

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

There is a major alarm.

NOTE: When you connectpower to the switch,

the alarm LED (ALM) glows red. This behavior is normal. Plugging an active Ethernet cable into the management port (MGMT) on the switch completes the network link and turns off the ALM LED. (See “Connecting a Device

to a Network for Out-of-Band Management” on page 167.)

Connecting the switch to a dedicated management console instead of a network does not affectthe ALM LED. The LED remains red until the switch is connected to a network.

There is a minor alarm.

NOTE: The ALM LED glows yellow if you

commit a configuration to make it active on the switch without creating a rescue configuration to back it up. To save the most recentlycommitted configuration as the rescue configuration, enter the operational mode command request system configuration rescue

•

Blinking—The switch is functioning normally and is the backup in the Virtual Chassis configuration.

•

Off—The switch is a linecard member in the Virtual Chassis configuration or is halted.

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

A minor alarm (yellow) indicates a noncritical condition that requires monitoring or maintenance. A minor alarm that is left unchecked might cause interruption in service or performance degradation.

All three LEDs can be lit simultaneously.

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.

Chapter 6: Preparation Overview

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 30 on page 53 provides the required environmental conditions for normal switch

operation.

Rack connection to buildingstructure

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 in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310–D) published by the Electronics Industry Association (http://www.eia.org).

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 in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310–D) published by the ElectronicsIndustry Association (http://www.eia.org).

•

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.

Requirements for Mounting an EX2300 Switch On or Under a Desk or Other Level Surface or On a 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.

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.

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 analysisto 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. 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 analysisto 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 budget is 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

Page 93

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 70.

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 38 on page 71 (here, the link is 2 km long and multimode, and the (PB) is 13 dBm):

Thisexampleassumes 2 splices.Loss for 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

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

PB– LL = P

) by subtracting (LL) from (PB):

Page 94

EX2300-C and EX2300 Switches Hardware Guide

(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.

Pluggable Transceivers Supported on EX2300 Switches

Uplink ports on the front panel in EX2300 switches support SFP and SFP+ transceivers. This topic describes the optical interfaces supported for those transceivers. It also lists the copper interface supported for the SFP transceivers. For the full specifications of these transceivers, see The Hardware Compatibility Tool.

NOTE: We recommend that you use only optical transceivers and optical

connectors purchased from Juniper Networks with your Juniper Networks device.

CAUTION: If you face a problemrunning a Juniper Networks device that uses

a third-party optic or cable, the Juniper Networks TechnicalAssistanceCenter (JTAC)can help you diagnose the source of the problem. Your JTAC engineer might recommend thatyou checkthe third-party optic or cableand potentially replaceit with an equivalent Juniper Networks optic or cable that is qualified for the device.

NOTE: EX2300-C switchesensure normal operationin the temperature range

32° F (0° C) through 104° F (40° C) at altitudes up to 5,000 ft (1,524 m). In the temperature range 104° F (40° C) through 113° F (45° C) at altitudes up to 5,000 ft (1,524 m), use extended temperature range SFP transceivers.
