Complete Hardware Guide for EX4500 Ethernet Switches

EX4500 Switches First View

EX4500 switches provide connectivity for high-density 10-Gigabit Ethernet data center top-of-rack and aggregation deployments. Typically, EX4500 switches are used in data centers where they can be positioned as the top device in a rack to provide connectivity for all devices in the rack.

The EX4500 switch is 2 rack units (2 U) in size. Each EX4500 switch is designed to optimize rack space utilization and cabling. See Figure 1 on page 4, Figure 2 on page 4, and Figure 3 on page 5.

NOTE: The side of the switch where the networkports are locatedis the front

of the switch.

Figure 1: EX4500 Switch Front

Figure 2: EX4500 Switch Rear with Intraconnect Module Installed

Chapter 1: EX4500 Switch Overview

Figure 3: EX4500 Switch Rear with Virtual Chassis Module Installed

EX4500 switches are availablein models with either front-toback airflowor back-to-front airflow and hardware that either supports or does not support Data Center Bridging (DCB), also known as Converged Enhanced Ethernet (CEE). See “EX4500 Switch Models”

on page 7. All eight models provide40 wire-speed10-gigabit small form-factorpluggable

(SFP+) network ports that can house either 1-Gigabit Ethernet transceivers or 10-Gigabit Ethernet transceivers. All models support two optional high-speed uplink modules.

To provide carrier-class reliability, EX4500 switches include:

•

Dual redundant, load-sharingpower supplies that are hot-insertableand hot-removable field-replaceable units.

•

An FRU fan tray with five fans. The switch remains operational if a single fan fails.

•

RedundantRouting Engines in a Virtual Chassis configuration. This redundancy enables graceful Routing Engine switchover (GRES).

•

Junos OS with its modular design that enables failed system processes to gracefully restart.

Intraconnect Module and Virtual Chassis Module

EX4500 switches ship with either the intraconnect module or the Virtual Chassis module preinstalled in the switch. Only one of the modules can be installed on the rear side of the switch chassis at a time. Both modules are offline FRUs.

•

Intraconnect module—The intraconnect module helps the switch achieve line rate on all its ports. See “Intraconnect Module in EX4500 Switches” on page 38.

•

Virtual Chassis module—The Virtual Chassis module has two dedicated Virtual Chassis ports (VCPs) that can be used to interconnect the EX4500 switch with EX4200 switches,EX4500 switches, or EX4550 switches to form a Virtual Chassis. See “Virtual

Chassis Module in EX4500 Switches” on page 39.

Complete Hardware Guide for EX4500 Ethernet Switches

NOTE: Operating an EX4500 switch without the intraconnect module or the

Virtual Chassis module is not supported. EX4500 switches running Junos OS Release 10.4R2 or later 10.4 releases will not boot if you do not install the intraconnect module in the switch. EX4500 switches running Junos OS Release 11.1R1 or later releases will not boot if you install neither the intraconnect module nor the Virtual Chassis module in the switch.

NOTE: The VirtualChassis module is supported on EX4500switches in Junos

OS Releases 11.1 and later.

Virtual Chassis

The number of EX4500 switches that can be interconnected into a Virtual Chassis composed exclusively of EX4500 switches depends on the Junos OS release running on the switches. See “Understanding EX4200, EX4500, and EX4550 Virtual Chassis

Hardware Configurations” on page 103.

Uplink Modules

EX4200,EX4500, and EX4550 switches can be connected together into the same Virtual Chassis to form a mixed Virtual Chassis. The number of EX4200, EX4500, and EX4550 switches that can be interconnected into a mixed Virtual Chassis depends on the Junos OS release running on the switches. See “Understanding EX4200, EX4500, and EX4550

Virtual Chassis Hardware Configurations” on page 103.

You can use the following ports to configure an EX4500 switch in a Virtual Chassis composed exclusively of EX4500 switches or in a mixed Virtual Chassis:

•

Dedicated VCPs on the Virtual Chassis module installed in the switch

•

SFP+ uplink module ports configured as VCPs

•

SFP+ fixed network ports configured as VCPs

For information about understanding and configuring VirtualChassis, see EX2200, EX3300, EX4200, EX4500 and EX4550 Virtual Chassis.

Optional uplink modules are available for EX4500 switches. You can install up to two uplink modules in an EX4500 switch. Each uplink module provides four SFP+ ports for connecting to core devices in a data center. You can install SFP or SFP+ transceivers in these ports. You can also configure the uplink module ports as VCPs to form a Virtual Chassis. For more information, see “Uplink Modules in EX4500 Switches” on page 36.

Power Supplies

EX4500 switches support both AC and DC power supplies. Each AC power supply is available in two different airflow models, front-to-back and back-to-front. DC power supplies are available only in the front-to-back airflow model.

Chapter 1: EX4500 Switch Overview

EX4500 switches ship with one AC or DC power supply installed. Youcan install a second AC or DC power supply in your EX4500 switch. See “AC Power Supply in EX4500

Switches” on page 27 and “DC Power Supply in EX4500 Switches” on page 30.

CAUTION: Mixing different types (AC and DC) of power supplies or power

supplies with front-to-back and back-to-front airflow in the same chassis is not supported.

CAUTION: Verify that the direction of airflow through the power supply

matches the direction of airflow through the fan tray to prevent overheating of the chassis.

Each AC power supply provides power to all components in the switch. The two power supplies provide full power redundancy to the switch. If one power supply fails or is removed, the second power supply balances the electrical load without interruption. The switch reassesses the power required to support the switch configuration and issues error messages if the available power is insufficient.

Figure 18: Fan Tray Used in an EX4500 Switch

The fan tray installs horizontally in the rear of the chassis. The fan tray has two handles, one on each side that facilitate handling of the fan tray.

You remove and replace the fan tray from the rear of the chassis. The switch continues to operate for a limited time (30 seconds) during the replacementof the fan tray without thermal shutdown.

The fan tray provides front-to-back or back-to-front airflow depending on the switch model you purchase.

NOTE: The side of the switch where the networkports are locatedis the front

of the switch.

Chapter 2: Component Descriptions

Figure 20: Back-to-Front Airflow Through the EX4500 Switch Chassis

Each fan tray has colored intake or exhaust labels that are visible through the fan tray vents. The INTAKE label is orange. The EXHAUST label is green.

NOTE: Only one of the labels, INTAKE or EXHAUST, is visible through the

vents of the installed fan tray.

The color of the label visible through the vents of the installed fan tray must match the color of the ejector lever on the installed power supply. The color match indicates that the powersupply has the correct airflow for this model. See “ACPowerSupply in EX4500

Switches” on page 27.

CAUTION: To prevent overheating of the chassis, verify that the color of the

label visible through the vents of the installed fan tray matches the color of the ejector lever of the installed power supply. A color match indicates that the direction of airflow through the fan tray matches the direction of airflow of the power supply.

Temperature sensors in the chassis monitor the temperature within the chassis. The fan tray used in the switch comes with load-sharing redundancy that can tolerate a single fan failure at room temperature (below 113° F/45° C) to still provide sufficient cooling.

Under normal operating conditions, the fans in the fan tray run at less than full speed. If a fan fails or the ambient temperature rises above the threshold 113° F (45° C), the speed of the remaining fans is automatically adjusted to keep the temperature within the acceptable range, 32° F (0° C) through 113° F (45° C).

The system raises an alarm if the fan fails or if the ambient temperatureinside the chassis rises above the acceptable range. If the temperature inside the chassis rises above the threshold temperature, the system shuts down automatically.

Uplink Modules in EX4500 Switches

EX4500 switches support SFP+ uplink modules. The SFP+ uplink module is a hot-insertable and hot-removable field replaceable unit (FRU).

NOTE: Uplink modules and transceivers are not part of the EX4500 switch’s

shipping configuration. You must order them separately.

You can install up to two SFP+ uplink modulesin an EX4500 switch. Both uplink modules install horizontally on the front of the chassis. The uplink module slot on the left is PIC 1. The uplink module slot on the right is PIC 2. See Figure 21 on page 36.

Figure 21: Uplink Module Slots in an EX4500 Switch

Each SFP+ uplink module provides four ports. Each module can house four 10-gigabit small form-factor pluggable (SFP+) transceivers or four 1-gigabit small form-factor pluggable (SFP) 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 required interfaces when new transceivers are installed in those ports.

Pluggable Transceivers Supported on EX4500 Switches

Uplink module ports on EX4500 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.

Complete Hardware Guide for EX4500 Ethernet Switches

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

connectors purchased from Juniper Networks with your Juniper Networks device.

CAUTION: If you are having a problem running a Juniper Networks device

that is using a third-party optic or cable, the Juniper Networks Technical Assistance Center (JTAC) can help you diagnose the source of the problem. Your JTAC engineer might recommend that you check the third-party optic or cable and potentially replace it with an equivalent Juniper Networks optic or cable that is qualified for the device.

The Gigabit Ethernet SFP and SFP+ transceivers installed in EX4500 switches support digital optical monitoring (DOM): Youcan view the diagnostic details for these transceivers by issuing the operational mode CLI command show interfaces diagnostics optics.

NOTE: The transceivers support DOM even if they are installed in uplink

module ports configured as Virtual Chassis ports.

Grounding Cable and Lug Specifications for EX4500 Switches

For installations that require a separate grounding conductor to the chassis, the switch must be adequately grounded before power is connected to ensure proper operation and to meet safety and electromagnetic interference (EMI) requirements. To ground an EX4500 switch, connect a grounding cable to earth ground and then attach it to the chassis grounding points.

CAUTION: For installations that require a separate grounding conductor to

the chassis, use the protective earthing terminal on the switch chassis to connect to earth ground. Before switch installation begins, a licensed electrician must attach a cable lug to the grounding cables that you supply. See “Connecting Earth Ground to an EX Series Switch” on page 137. A cable with an incorrectly attached lug can damage the switch.

A pair of threaded inserts (PEM nuts) is provided on the left side towards the rear corner of the chassis for connecting the switch to earth ground. The grounding points fit UNC 10-32 screws. The grounding points are spaced at 0.625 in. (15.86 mm).

The grounding cable that you provide for an EX4500 switch must be 14 AWG (2 mm2), minimum 90°C wire, or as permitted by the local code.

NOTE: Grounding is provided to an AC-powered switch when you plug its

power supplies into grounded AC power receptacles.

Chapter 4: Site Preparation

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.

•

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.

Table28 on page 80 describes the factors you must consider whileplanning the electrical

wiring at your site.

WARNING: It is particularly important to provide a properly grounded and

shielded environment and to use electrical surge-suppression devices.

Complete Hardware Guide for EX4500 Ethernet Switches

Table 28: Site Electrical Wiring Guidelines

GuidelinesSite Wiring Factor

Signaling limitations

Radio frequency interference

Electromagnetic compatibility

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).

•

Damagefrom lightning strikesoccurswhen wires exceedrecommended distances or pass between buildings.

•

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

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-paircablewith 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 switch

•

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

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 29 on page 82 provides the required environmental conditions for normal switch

operation.
