Juniper Networks EX2200 manual Port Parameters State and Description

Chapter 2: Component Descriptions

The LEDs labeled Status LED in Figure 5 on page 12 and Figure 6 on page 12 indicate the status of one of the four port parameters—speed, duplex mode, administrative status, and Power over Ethernet (PoE) status. Use the mode button below the POE LED on the far right side of the front panel to toggle the Status LED to show the different port parameters. You can tell which port parameter is indicated by the Status LED by seeing which port status mode LED (SPD, DX, EN, and POE) is lit. (See Figure 6 on page 12).

Table 6 on page 13 describes the Status LED.

Table 6: Status LED on the Network Ports and Uplink Ports in EX2200 Switches

Port Parameters	State and Description
Speed	Indicates the speed. The speed indicators for network ports are:

•One blink per second—10 Mbps

•Two blinks per second—100 Mbps

•Three blinks per second—1000 Mbps

The speed indicators for uplink ports are:

	•	On steadily—1000 Mbps
	•	Off—10/100 Mbps
Duplex mode	Indicates the duplex mode. The status indicators are:
	• On steadily—Port is set to full-duplex mode.
	• Off—Port is set to half-duplex mode.
Administrative status	Indicates the administrative status. The status indicators are:
	• On steadily—Port is administratively enabled.
	• Off—Port is administratively disabled.
PoE status	Indicates the PoE status. The status indicators for network ports are:
	• On steadily—PoE is available on the port, a device that draws power from the port
		is connected to the port, and the device is drawing power from the port.
	• Blinking—PoE is available on the port, but no power is drawn from the port because
		of one of the following:
		• No device that draws power from the port is connected to the port.
		• A device that draws power from the port is connected to the port, but the device
		is not drawing any power from the port.
	• Off—PoE is not available on the port.
	PoE is not available on uplink ports; therefore, the LED for those ports is always unlit.

You can tell which port parameter is indicated by the Status LED on network ports and uplink ports by issuing the operational mode command show chassis led.
