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 1 shows the LEDs on the 10/100/1000BASE-T and 100/1000/2500/5000/10000BASE-T Ethernet network ports.

  • Figure 2 shows the LEDs on the SFP network ports on EX4300-32F switches.

  • Figure 3 shows the LEDs on the built-in QSFP+ ports.

  • Figure 4 shows the LEDs on the SFP+ uplink ports and on the uplink module ports on the 4-port 1-Gigabit Ethernet/10-Gigabit Ethernet SFP+ uplink module for EX4300 switches except EX4300-48MP and EX4300-48MP-S switches.

  • Figure 5 shows the LEDs on the ports on the 2-port 40-Gigabit Ethernet QSFP+ uplink module for EX4300-32F switches.

  • Figure 6 shows the LEDs on the ports on the 8-port 10-Gigabit Ethernet SFP+ uplink module for EX4300-32F switches.

  • Figure 7 shows the LEDs on the ports on the 2-port 40-Gigabit Ethernet QSFP+/1-port 100-Gigabit Ethernet QSFP28 uplink module for EX4300-48MP and EX4300-48MP-S switches.

  • Figure 8 shows the LEDs on the ports on the 4-port 10-Gigabit Ethernet SFP+ uplink module for EX4300-48MP and EX4300-48MP-S switches.

Status LED

There are four LEDs for each port (labeled 2, 3, 4, and 5 in Figure 7). If a port is configured to operate at 10-Gbps speed by using breakout cables, four 10-Gbps interfaces are created and the four LEDs for that port becomes operational. Each of these LEDs indicates the link activity on the corresponding interface. If a port is configured to operate at 40-Gbps or 100-Gbps speed, the LED labeled 2 for that port in Figure 7 becomes operational and indicates the link activity on the corresponding port.

The Table 1 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, QSFP+ uplink module ports, and QSFP+/QSFP28 uplink module ports.

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.

On EX4300 switches except EX4300-48MP and EX4300-48MP-S switches, 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.

Table 2 describes the Status LED on 10/100/1000BASE-T Ethernet network ports and SFP network ports on EX4300 switches except EX4300-48MP and EX4300-48MP-S switches.

LCD Indicator/Status Mode LED

State and Description

Status

LED: ADM/EN

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

  • Green—Port is administratively enabled.

  • Unlit—Port is administratively disabled.

LED: DPX/DX

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/SPD

Indicates the speed. The speed indicators 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/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 3 describes the Status LED on SFP+ uplink ports and SFP+ uplink module ports on EX4300 switches except EX4300-48MP and EX4300-48MP-S switches.

Status

Green

Indicates the status. The status indicators are:

  • Unlit—40-Gigabit port is down.

  • Steadily green—40-Gigabit port is up.

Table 5 describes the Status LED on 100/1000/2500/5000/10000BASE-T Ethernet network ports on EX4300-48MP and EX4300-48MP-S switches. Use the Factory Reset/Mode button on the far right side of the front panel to toggle the Status LED to show the different port parameters for the RJ-45 network ports. You can tell which port parameter is indicated by the Status LED by looking at which port status mode LED (SPD, DX, EN, and PoE) is lit.
