EX3300 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 EX3300 Ethernet Switches provide connectivity for low-density environments.

•

EX3300 Switches First View on page 3

•

Uplink Ports on page 4

•

Power over Ethernet Plus Ports on page 4

EX3300 Switches First View

EX3300 switches provide:

•

Either 24 or 48 built-in network ports with 10/100/1000BASE-T Gigabit Ethernet connectors (ports labeled 0 through 23 or 0 through 47)

•

Four uplink ports (ports labeled 0 through 3)

•

Virtual Chassis capability—You can connect up to ten EX3300 switches together to form one unit that you manage as a single chassis, called a Virtual Chassis.

•

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

EX3300 Switch Hardware Guide

Uplink Ports

Each EX3300 switch has four autosensing uplink ports. You can use the uplink ports on the switch to:

•

Connect an access switch to a distribution switch

•

Interconnect member switches of a Virtual Chassis

The uplink ports labeled 0 and 1 (interfaces ge-0/1/0 and ge-0/1/1 or xe-0/1/0 and

xe-0/1/1) are configured by default as network ports. To use uplink ports 0 and 1 to

interconnectVirtual Chassis members, you must configure them as Virtual Chassis ports (VCPs).

The uplink ports labeled 2 and 3 (interfaces ge-0/1/2 and ge-0/1/3 or xe-0/1/2 and

xe-0/1/3) are configured by default as VCPs. You can use these uplink ports to

interconnect Virtual Chassis members. To use uplink ports 2 and 3 as network ports, you must configure them as network ports.

The uplink ports support SFP and SFP+ transceivers. For a list of supported transceivers, see “Pluggable Transceivers Supported on EX3300 Switches” on page 71.

Power over Ethernet Plus Ports

EX3300 switches are available in models with or without PoE+ capability. Models that support 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.

Documentation

Under normal operating conditions, the fans operate at moderate speeds for minimal 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.

Power Supply in EX3300 Switches

The power supply in EX3300 switches is built in along the rear panel of the chassis, with an AC power cord inlet or DC power terminal block on the rear panel to connect power to the switch.

NOTE: After powering on 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.

Afterthe switch has beenpowered on, it cantake up to 60 secondsfor status indicators—suchasshow chassis command outputand messageson the LCD panel—toindicate that the power supplyis functioning normally. Ignore error indicators that appear during the first 60 seconds.

Table 14 on page 27 lists the power consumed by each EX3300 switch model. The

maximum power available on a PoE+ port is 15.4 W.

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 53 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 airflowguidelines toensure 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.

Documentation

You can mount the device on a rack that providesbracket 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

Cabinet Requirement

Cabinet clearance

Guidelines

•

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.

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 themaximum amount of powerthe link cantransmit. When youcalculate

EX3300 Switch Hardware Guide

the powerbudget, youuse a worst-caseanalysis 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 valuesfor thelink's minimum transmitterpower (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 powermargin, 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 powerbudget 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 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 67.

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 40 on page 69 (here, the link is 2 km long and multimode, and the (PB) is 13 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

(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 greater than 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.
