Network Port and Uplink Port LEDs in EX3300 Switches

Each network port and uplink port on the front panel of an EX3300 switch has two LEDs that indicate link/activity and port status. See Figure 7 and Figure 8.

Table 8 describes the Link/Activity LED.

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.

The LEDs labeled Status LED in Figure 7 and Figure 8 indicate the status of one of the four port parameters—speed, administrative status, duplex mode, and Power over Ethernet Plus (PoE+) status. From the Idle menu of the LCD, use the Enter button on the LCD panel to toggle between the SPD, ADM, DPX, and POE, indicators.

Table 10 describes the Status LED on the network ports and table describes the Status LED on the uplink ports.

LCD Indicator

State and Description

Status

LED: SPD

Indicates the speed.

The status indicators are:

  • Unlit—10 Mbps
  • Blinking—100 Mbps
  • On steadily—1000 Mbps

LED: ADM

Indicates the administrative status. The status indicators are:

  • On steadily—Port is administratively enabled.
  • Off—Port is administratively disabled.

LED: DPX

Indicates the duplex mode.

The status indicators are:

  • Green—Port is set to full-duplex mode.
  • Unlit—Port is set to half-duplex mode.

LED: POE

Indicates the PoE status.

The status indicators are:

  • On steadily—PoE is available on 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.
  • Unlit—PoE is not enabled on the port.

State and Description

Status

LED: SPD

Indicates the speed.

The status indicators are:

  • Unlit—10/100 Mbps
  • Blinking—1000 Mbps
  • On steadily—10 Gbps

LED: ADM

Indicates the administrative status. The status indicators are:

  • On steadily—Port is administratively enabled.
  • Off—Port is administratively disabled.

LED: DPX

Indicates the duplex mode.

The uplink ports are always set to full-duplex; therefore, the LED for uplink ports is always green.

LED: POE

Indicates the PoE status.

PoE is not enabled on uplink ports; therefore, the LED for uplink ports is always unlit.
