You can mount an EX6210 switch on two or four posts of a standard 19-in. rack or a standard 800-mm enclosed cabinet. Up to three EX6210 switches can be installed in a standard (42 rack unit (U)) rack provided the rack can handle their combined weight.

Field-Replaceable Units in an EX6210 Switch

Field-replaceable units (FRUs) are switch components that you can replace at your site. The switch uses these types of FRUs:

  • Hot-insertable and hot-removable—You can remove and replace these components without powering off the switch or disrupting the switching function.

  • Hot-pluggable—You can remove and replace these components without powering off the switch, but the switching function is interrupted until you replace the component.

Table 2 lists the FRUs for the EX6210 switch and their types.

Note

If you have a Juniper J-Care service contract, register any addition, change, or upgrade of hardware components at https://www.juniper.net/customers/support/tools/updateinstallbase/ . Failure to do so can result in significant delays if you need replacement parts. This note does not apply if you replace existing components with the same type of component.

Understanding EX6210 Switch Component and Functionality Redundancy

The Juniper Networks EX6210 Ethernet Switch is available as a fully redundant system. A redundant switch configuration is so designed that no single point of failure can cause the entire switch to fail. See EX6210 Switch Configurations.

Hardware Components That Provide Redundancy

The following hardware components provide redundancy to an EX6210 switch:

  • SRE modules—An EX6210 switch can have either one or two Switch Fabric and Routing Engine (SRE) modules. At least one SRE module must be installed in the switch. If two SRE modules are installed, one SRE module functions as the master and the other functions as the backup. If the master SRE module fails or is removed the backup module takes over as the master SRE module.

    When the SRE modules are configured for graceful switchover, the backup SRE module automatically synchronizes its configuration and state with those of the master SRE module. Any update to the master SRE module is replicated on the backup SRE module. If the backup module assumes mastership, packet forwarding continues through the switch.

    Each SRE module provides 64 Gbps of full-duplex bandwidth per line card slot. If only one SRE module is installed in a chassis, it supports 384 ports on eight line cards with 3:2 oversubscription. If two SRE modules are installed in a chassis, they provide 128 Gbps of full-duplex bandwidth to each line card slot, allowing all 384 ports to operate at wire speed.

  • Power supplies—You can install up to four AC or four DC power supplies in an EX6210 switch. Each power supply connects to the backplane of the chassis, which distributes the output power produced by the power supplies to different switch components. (See Backplane in an EX6210 Switch.) Each power supply provides power to all the components in the switch.

    An N+1 power configuration is recommended for EX6200 switches. By default, the power management feature in EX6200 switches is configured to manage the power supplies for N+1 redundancy, in which one power supply is held in reserve for backup if any one of the other power supplies is removed or fails. In an N+1 power configuration, if one power supply fails or is removed, the remaining power supplies continue to supply power for the entire system without interruption.

    If dual power feed redundancy is required, you can configure power management to manage the power supplies for N+N redundancy. In N+N redundancy, power management allocates half of the online power supplies to normal operating power and half to redundant power. If you have an odd number of online power supplies, power management allocates one more power supply to normal operating power than to redundant power. To configure the power supply redundancy of your switch, see Configuring Power Supply Redundancy (CLI Procedure).

    For details about the power supply, see AC Power Supplies in an EX6200 Switch and DC Power Supply in an EX6200 Switch.

    Caution

    Mixing different types (AC and DC or AC power supplies of different wattage) of power supplies in the same chassis is not supported.

    Mixing low-voltage input line and high-voltage input line power feeds in the same chassis is not supported.

  • Cooling system—The cooling system in an EX6210 switch consists of a single fan tray. The fan tray contains six fans, three rows of two fan each. Under normal operating conditions, the fans in the fan tray run at less than full speed.

    The fans in the fan tray continue to operate indefinitely and provide sufficient cooling even when a single fan fails provided the room temperature is within the operating range. See EX6210 Switch Cooling System.

Routing Engine and Control Redundancy

Each SRE module contains switch fabric circuitry, Routing Engine circuitry, and switch control and management circuitry. An EX6210 switch can have one or two SRE modules. If the switch has two SRE modules, one functions as the master while the other functions as a backup. This provides the switch with full redundancy (1+1) for Routing Engine, and switch control functionality. The switch fabric circuitry on the backup SRE module is active; this allows the ports on the switch to operate at wire speed. You can also use the uplink ports on the backup SRE module.

Table 3 shows the available slots in the EX6210 chassis and the Routing Engine and control redundancy associated with different SRE module combinations.

LCD Panel in an EX6200 Switch

The LCD panel is on the front faceplate of the Switch Fabric and Routing Engine (SRE) module on the right side. Your switch can have up to two LCD panels, one for each SRE module installed in the chassis.

The LCD panel on the master SRE module shows two lines of text with a maximum of 16 characters in each line. This LCD panel displays a variety of information about the switch and provides menu options to perform basic operations such as initial configuration and switch reboot.

Note

The LCD menu on the backup SRE module displays the text BACKUP. No menu options are displayed on the backup LCD panel.

There are two navigation buttons—Menu and Enter—to the right of the LCD panel on each SRE module.

See Figure 4.

Figure 4: LCD Panel in an EX6200 Switch

Backplane in an EX6210 Switch

The backplane is a printed circuit board that forms the back of the line card cage. The Switch Fabric and Routing Engine (SRE) modules, power supplies, and line cards plug into the backplane from the front of the chassis. The backplane contains an EEPROM that stores the serial number and revision level of the backplane.

The backplane performs the following functions:

  • Power distribution—The backplane distributes power to all the switch components from the power supplies that plug into it.

  • Control-signal connectivity—The backplane transports the control signals exchanged by system components for monitoring, control, and management purposes.

  • Transfer of data between line cards and SRE modules—The backplane provides connectivity for data traffic to and from the line cards and the SRE modules.

Warning

High levels of electrical energy are distributed across the switch backplane. Do not touch the backplane connectors, or any component connected to the backplane, with any metallic object while servicing components installed in the switch or while replacing the fan tray.

Switch Fabric and Routing Engine (SRE) Module in an EX6200 Switch

The Switch Fabric and Routing Engine (SRE) module performs switching and system management functions in an EX6200 switch. It also provides uplink connectivity through four 10-gigabit SFP+ uplink ports. See Figure 5.

You can install one or two SRE modules in an EX6200 switch. A non-redundant EX6210 switch configuration has only one SRE module. You can add a second SRE module to the configuration for Routing Engine and switch control redundancy. See Understanding EX6210 Switch Component and Functionality Redundancy.

The SRE modules install horizontally into the front of the chassis in slots labeled 4 and 5.

Figure 5: SRE Module in an EX6200 Switch
SRE Module in an EX6200
Switch
Note

We recommend that you install two SRE modules for redundancy. If you install only one SRE module, we recommend that you install it in slot 4. See Slot Numbering for an EX6210 Switch.

If two SRE modules are installed, one functions as the master and the other acts as the backup. If the master SRE module fails or is removed, the backup takes over as the master. The switch fabric circuitry on the backup SRE module is active; this allows the ports on the switch to operate at wire speed. You can also use the uplink ports on the backup SRE module.

If two SRE modules are installed, the master and backup SRE modules are hot-pluggable. If only one SRE module is installed, you must halt the SRE module before removing it. See Taking the SRE Module Offline in an EX6200 Switch.

Each SRE module provides 64 Gbps of full duplex bandwidth per line card slot. If only one SRE module is installed in a chassis, it supports 384 ports on eight line cards with 3:2 oversubscription. If two SRE modules are installed in a chassis, they provide 128 Gbps of full duplex bandwidth to each line card slot, allowing all 384 ports to operate at wire speed.

The SRE module provides these functions:

  • Provides full fabric connectivity to all line cards installed in the chassis

  • Powers the line cards on and off

  • Controls system resets and boot sequence for the switch

  • Monitors and controls the fan speed, power status for various chassis components, LCD panel and chassis status LEDs

  • Provides uplink connectivity



The SRE module has these components:

  • Four uplink ports—Four 10-gigabit Ethernet SFP+ uplink ports. The ports are labeled from left to right, 0 through 3. Since the switch fabric circuitry on the backup SRE module is active, you can use the four uplink ports on the backup SRE module for uplink connectivity.

  • Two management ports—A Gigabit Ethernet SFP management port and a 10/100/1000 BASE-T copper management port. The management ports can be used to connect the SRE module to a management LAN for out-of-band management. See Connecting a Device to a Network for Out-of-Band Management.

    Note

    Only one of the two management ports can be used for out-of-band management at any given time. If an SFP transceiver is plugged into the SFP management port, the copper management port is disabled.

  • Console port—Connects the SRE module to a system console through a cable with an RJ-45 connector. See Connecting a Device to a Management Console by Using an RJ-45 Connector.

  • USB port—Provides an interface through which you can install the Junos OS or a configuration file manually. See USB Port Specifications for an EX Series Switch.

  • Recessed reset button—Power cycles the SRE module when pressed.

    Take the SRE module offline using the CLI before pressing the reset button. See Taking the SRE Module Offline in an EX6200 Switch.

  • LCD Panel—Displays status information for the switch. See LCD Panel in an EX6200 Switch.

  • Chassis Status LEDs—Indicate SRE module status and system status. See Chassis Status LEDs in an EX6200 Switch.

  • Ejector levers—Used for installing and removing the SRE module.

  • Captive screws—Secure the SRE module in place.



SRE Module LEDs in an EX6200 Switch

Each Switch Fabric and Routing Engine (SRE) module has three groups of LEDs on the module’s front panel (see Figure 6):

  • Uplink port LEDs—The SRE module has four 10-gigabit SPF+ uplink ports on the module’s front panel. Each uplink port has two LEDs. Uplink Port LEDs in EX6200 Switches describes these LEDs, their colors and states, and the status they indicate.

  • Management port LEDs—Each SRE module has two management ports. Each management port has two LEDs: link/activity and status. Management Port LEDs in EX6200 Switches describes these LEDs, their colors and states, and the status they indicate.

  • Chassis Status LEDS—Each SRE module has three LEDS to the right of the LCD Panel: Alarm (ALM), System (SYS), and Master (MST). Chassis Status LEDs in an EX6200 Switch describes these LEDs, their colors and states, and the status they indicate.

Grounding Cable and Lug Specifications for EX6200 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 EX6200 switch, connect a grounding cable to earth ground on one side, attach the other side to the cable lug, and then attach the cable lug to the chassis grounding point.

Note

Grounding is required for DC systems and recommended for AC systems. An AC-powered switch gets additional grounding when you plug the power supply installed in the switch into a grounded AC power outlet using the appropriate power cord.

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. A cable with an incorrectly attached lug can damage the switch.

A pair of threaded inserts (PEM nuts) is provided on the rear towards the bottom of the EX6210 chassis for connecting the switch to earth ground. The grounding points fit UNC ¼-20 screws. The grounding points are spaced at 0.625 in. (15.86 mm). See Figure 11 for the location of the protective earthing terminal.

Note

A grounding lug (Panduit LCD2-14A-L), two ¼-20 x 0.5 screws and two flat washers are shipped with the EX6210 chassis.

The grounding cable that you provide for the switch must be the same gage as the power source cables or as permitted by the local code.

Warning

The switch is pluggable type A equipment installed in a restricted-access location. It has a separate protective earthing terminal provided on the chassis in addition to the grounding pin of the power supply cord. This separate protective earthing terminal must be permanently connected to earth ground for installations that require a separate grounding conductor to the chassis.
