Network Port LEDs in EX3200 and EX4200 Switches

Each network port on an EX3200 or EX4200 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.

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.

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.

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.

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.
