Network Port and Uplink Port LEDs in EX2200 Switches

Each network port and uplink port on the front panel of an EX2200 switch has two LEDs that indicate link/activity and port status. Each dual-purpose uplink port in an EX2200-C switch has two pairs of LEDs that indicate the link/activity status, one pair for each of the two ports that constitute the dual-purpose uplink port. See Figure 9, Figure 10, and Figure 11.

Figure 9: LEDs on the Network Port

Table 7 describes the Link/Activity LED.

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.

In Figure 9, Figure 10, and Figure 11 show the LEDs that 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 10).

Table 8 describes the Status LED.

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

The speed indicators for dual-purpose uplink ports of EX2200-C switch model are:

  • One blink per second—10 Mbps
  • Two blinks per second—100 Mbps
  • Three blinks per second—1000 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.

Note: PoE Status LED is available on the following EX2200 switch models:

  • EX2200-C-12P-2G
  • EX2200-24P-4G
  • EX2200-48P-4G

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, uplink ports, and dual-purpose uplink ports by issuing the operational mode command show chassis led.
