Network Port, Built-In QSFP+ Port, Uplink Port, and Uplink Module Port LEDs on EX4300 Switches

Each 10/100/1000BASE-T network port, SFP network port, SFP+ uplink port, SFP+ uplink module port, built-in QSFP+ port, and QSFP+ uplink module port on an EX4300 switch has two LEDs that show the link activity and status of the port.

The following figures in this topic shows the location of those LEDs:

  • Figure 14 shows the location of the LEDs on the 10/100/1000BASE-T Ethernet network ports.
  • Figure 15 shows the location of the LEDs on the SFP network ports.
  • Figure 16 shows the location of the LEDs on the built-in QSFP+ ports.
  • Figure 17 shows the location of the LEDs on the SFP+ uplink ports and on the SFP+ uplink module ports on the 4-port SFP+ uplink module.
  • Figure 18 shows the location of the LEDs on the QSFP+ uplink module ports on the QSFP+ uplink module.
  • Figure 19 shows the location of the LEDs on the SFP+ uplink module ports on the 8-port SFP+ uplink module.

The Table 14 describes the link activity LED on 10/100/1000BASE-T network ports, SFP network ports, SFP+ uplink ports, SFP+ uplink module ports, built-in QSFP+ ports, and QSFP+ uplink module 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 15 describes the Status LED on 10/100/1000BASE-T Ethernet network ports and SFP network ports. From the Idle menu of the LCD panel, use the Enter button on the LCD panel to toggle between the ADM, DPX, SPD, and PoE+ indicators.

LCD Indicator

State and Description

Status

LED: ADM

Indicates the administrative status (enabled or disabled). The status indicators are:

  • Green—Port is administratively enabled.
  • Unlit—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.

Note: In EX4300 switches, the ports operate in full-duplex mode only.

LED: SPD

Indicates the speed. The speed indicators for 24-port and 48-port EX4300 switches are:

  • Unlit—10 Mbps
  • Blinking green—100 Mbps
  • Steadily green—1000 Mbps

Note: In 32-port EX4300 switches, when an EX-SFP-1GE-T transceiver is installed in the port, the LED is unlit when the speed is 100 Mbps.

LED: PoE

Indicates the PoE mode. The status indicators are:

  • Steadily green—PoE is enabled on the port and a device is drawing power.
  • Blinking green—PoE is enabled on the port, but no power is drawn from the port.
  • Unlit—PoE is not enabled on the port.

Table 16 describes the Status LED on SFP+ uplink ports and SFP+ uplink module ports.
