BenefitsoftheEX2200Switch

Support for Virtual Chassis—EX2200 switches support Virtual Chassis technology. You can interconnect up to four EX2200 switches to form a Virtual Chassis and manage and operate them as a single network entity.

High flexibility—EX2200 switches provide a flexible solution that supports converged data, voice, and videoenvironments.EX2200switchesprovide15.4wattsofClass3PoEtoVoIPtelephones,closed-circuit security cameras, wireless access points, and other IP-enabled devices.

Economical—EX2200 switches offer an economical, entry-level, stand-alone solution for access layer deployments in branch and remote offices, as well as campus networks.

EX2200SwitchesFirstView

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,fanlessmodel),24,or48built-innetworkportswith10/100/1000BASE-TGigabitEthernet 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, calleda VirtualChassis. ForinformationaboutunderstandingandconfiguringVirtualChassis,see Virtual ChassisUserGuideforEX2200,EX3300,EX4200,EX4500andEX4550Switches.

•Power over Ethernet (PoE or PoE+) on all network ports (in PoE-capable models)

UplinkPorts

Only one of the ports can be active at a time. By default, if you connect a copper Ethernet cable to the RJ-45port,thisportbecomestheactiveportprovidedthatthereisnoconnectionmadeontheotherport. If you plug a transceiver into the SFP port, this port becomes the active port whether or not a copper Ethernetcableisconnectedtotheotherport.Youcanchangethisdefaultbehaviorbyexplicitlyconfiguring a media type—copper or fiber—for the dual-purpose port by using the media-type command. For more information, see ConfiguringtheMediaTypeonDual-PurposeUplinkPorts .

20

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 connectedasaVCP. See SettinganUplinkPortonanEXSeriesorQFXSeriesSwitchasaVirtualChassisPort.

Forinformationaboutthesupportedopticalandcopperinterfaces,see“PluggableTransceiversSupported on EX2200 Switches” on page 55.

ConsolePort

Each EX2200 switch except the EX2200-C switch model has an RJ-45 console port that accepts a cable with RJ-45 connector.

TheEX2200-Cswitchhastwoconsoleports:anRJ-45portandaMini-USBType-Bport.TheRJ-45console port accepts a cable with an RJ-45 connector and the Mini-USB Type-B console port accepts a Mini-B plug(5-pin)connectortoconnecttotheconsolemanagementdevice.Theswitchactivatesonlyoneconsole port at a time, either the RJ-45 console port or the Mini USB type-B console port.

PoweroverEthernet(PoE)Ports

EX2200 switches are available in models with or without PoE/PoE+ capability. Models that support PoE/PoE+providethatsupportonallnetworkports.PoEportsprovideelectricalcurrenttodevices—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.

21

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,youcanexecutePoEcommandsfromanon-PoE-capableswitchthatistheprimary,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.

FrontPanelofanEX2200Switch

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

Table 6 on page 30 describes the chassis status LEDs in an EX2200 switch, their colors and states, and the status they indicate.

Table6:ChassisStatusLEDsinanEX2200Switch

LED Label	Color	State and Description
SYS	Green	• On steadily—The switch is functioning normally.
		• Blinking—The switch is booting.
		• Off—The switch is powered off or is halted.
ALM	Unlit	There is no alarm or the switch is halted.
	Amber	There is a minor alarm.
	Red	There is a major alarm.

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

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

Both LEDs can be lit simultaneously.

You can view the colors of the two LEDs remotely through the CLI by issuing the operational mode command showchassisled.

ManagementPortLEDsinEX2200Switches

The management port on an EX2200 switch has two LEDs that indicate link/activity and port status. The EX2200 switches except the EX2200-C switch models have the management port on the rear panel and the EX2200-C switch has the management port on the front panel. See Figure 9 on page 31 and Figure 10 on page 31.
