Indicator LED ex3200 Switch Junipers

Each network port on the switch has two LEDs. The four figures in this topic show the location of those LEDs:

• Figure 1 shows the location of the LEDs on the network ports on the front panel.
• Figure 2 shows the location of the LEDs on the uplink module ports on the SFP uplink module.
• Figure 3 shows the location of the LEDs on the uplink module ports on the SFP+ uplink module.
• Figure 4 shows the location of the LEDs on the uplink module ports on the XFP uplink module.

Figure 1: LEDs on the Network Ports on the Front Panel

Figure 2: LEDs on the Uplink Module Ports on the SFP Uplink Module

Figure 3: LEDs on the Uplink Module Ports on the SFP+ Uplink Module

Figure 4: LEDs on the Uplink Module Ports on the XFP Uplink Module

The LEDs labeled Link/Activity LED in Figure 1, Figure 2, Figure 4, and Figure 3 indicate link activity. The LEDs labeled Status LED in Figure 1, Figure 2, Figure 4, and Figure 3 indicate the status of one of the four port parameters. The port parameters are administrative status, duplex mode, Power over Ethernet (PoE) status, and speed.

Table 1 describes the Link/Activity LED.

Table 1: Link/Activity LED on Network Ports

LED	Color	State and Description
Link/Activity	Green	Blinking—The port and the link are active, and there is link activity. On steadily—The port and the link are active, but there is no link activity. Off—The port is not active.

Table 2 describes the Status LED. From the Idle menu of the LCD, use the Enter button on the LCD panel to toggle between the ADM, DPX, POE, and SPD indicators.

Table 2: Status LED on Network Ports

LED	LCD Indicator	State and Description
Status	LED: ADM	Indicates the administrative status (enabled or disabled). The status indicators are: Green—Administrative status enabled. Unlit—Administrative status disabled.
	LED: DPX	Indicates the duplex mode. The uplink module ports are always set to full-duplex; therefore, the LED is always green. The status indicators for network ports on the front panel are: Green—Port is set to full-duplex mode. Unlit—Port is set to half-duplex mode.
	LED: POE	Indicates the PoE status on switches with PoE-enabled ports. Here the term POE refers to both PoE and PoE+ as applicable. PoE is not enabled on uplink module ports; therefore, the LED for those ports is always unlit. The status indicators for network ports on the front panel are: Green—PoE is enabled on the port. Amber—PoE is enabled 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. Unlit—PoE is not enabled on the port.
	LED: SPD	Indicates the speed. The speed indicators for network ports on the front panel are: One blink per second—10 Mbps Two blinks per second—100 Mbps Three blinks per second—1000 Mbps The speed indicators for network ports on the SFP uplink module are: Green—1000 Mbps Unlit—10/100 Mbps The speed indicators for network ports on the SFP+ uplink module are: Green—The speed of the transceiver installed in the port is the same as the speed at which the uplink module port is configured to operate. Unlit—The speed of the transceiver installed in the port is not the same as the speed at which the uplink module port is configured to operate. The speed of the XFP uplink module ports is always 10 Gbps; therefore, the LED is always green.
