EX-series Switch—SFP Uplink Module Port LEDs

The ports on the small-form factor pluggable transceiver (SFP) uplink module have two LEDs. Figure 1 shows the SFP uplink module port and the location of the LEDs on the port.

The LEDs labeled LED 1 in Figure 1 indicate link status, and the LEDs labeled LED 2 in Figure 1 indicate the status of one of the four port parameters. The port parameters are: administrative status; duplex mode; PoE status; and speed.

State and Description

LED 1

Unlit

No link activity.

Green

  • On steadily—The port is up and the link is active, but there is no link activity.
  • Blinking—The port is up, with active links.

Table 2 describes LED 2, which indicates the administrative status (enabled or disabled), duplex mode, PoE status, or speed, of the SFP uplink module ports. 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.

LCD Indicator

State and Description

LED 2

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 SFP uplink module ports ares always set to full-duplex; therefore, the LED is always green.

    LED: POE

    Indicates the PoE status. PoE is not available on the SFP uplink module ports; therefore, the LED is always unlit.

      LED: SPD

      Indicates the speed. The status indicators are:

      • Green—1000 Mbps
      • Unlit—10/100 Mbps
