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.

EX2200 switches provide:

  • Up to four uplink ports
  • 12 (compact, fanless model), 24, or 48 built-in network ports 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.

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.

Console Port

Each EX2200 switch except the EX2200-C switch model has an RJ-45 console 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).

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.

Security Slots

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

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.

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

Front Panel of an EX2200 Switch

The front panel of an EX2200 switch except the EX2200-C switch models consists of the following components:

  • Network ports—depending on the switch model, either of:
    • 24 or 48 10/100/1000BASE-T Gigabit Ethernet ports, with Power over Ethernet (PoE) not available in EX2200-24T, EX2200-24T-DC, and EX2200-48T models
    • 24 or 48 10/100/1000BASE-T Gigabit Ethernet ports, with Power over Ethernet (PoE) available in EX2200-24P and EX2200-48P models

Rear Panel of an EX2200 Switch

The rear panel of the EX2200 switch except the EX2200-C switch models consists of the following components:

  • Management Ethernet port
  • USB port
  • Console port
  • Protective earthing terminal
  • Redundant power system (RPS) port
  • ESD point
  • Air exhaust
  • Serial number ID label
  • AC power cord inlet or DC power terminals

Figure 5 shows the rear panel of an EX2200 switch with an AC power supply.

All EX2200 switches except the EX2200-C switch model have three exhaust openings on the rear panel. The two exhaust openings on the left have fans behind them and are open. The exhaust opening on the right has no fan within it. This opening is exposed on Power over Ethernet (PoE) models and sealed on non-PoE models. On PoE models, this opening exhausts the air from the fan at the air intake for the power supply on the side panel.

The power cord retainer clips extend out of the chassis by 3 in.

  • ESD point
  • Serial number ID label
  • AC power cord inlet
  • Heatsink—only in PoE+ models

Figure 6 shows the rear panel of an EX2200-C-12P switch with heatsink.

EX2200-C switches being fanless models have no exhaust openings. The switch has vents on the top and on both the sides of the chassis. The PoE+ models have a heatsink installed in the rear panel to dissipate the heat, while non-PoE models have no heatsink.
