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 acvity and status of the port.
The following gures in this topic shows the locaon of those LEDs:
• Figure 30 on page 75 shows the LEDs on the 10/100/1000BASE-T and
100/1000/2500/5000/10000BASE-T Ethernet network ports.
• Figure 31 on page 75 shows the LEDs on the SFP network ports on EX4300-32F switches.
• Figure 32 on page 75 shows the LEDs on the built-in QSFP+ ports.
• Figure 33 on page 76 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 34 on page 76 shows the LEDs on the ports on the 2-port 40-Gigabit Ethernet QSFP+ uplink
module for EX4300-32F switches.
• Figure 35 on page 77 shows the LEDs on the ports on the 8-port 10-Gigabit Ethernet SFP+ uplink
module for EX4300-32F switches.
• Figure 36 on page 77 shows the LEDs on the ports on the 2-port 40-Gigabit Ethernet QSFP+/100-
Gigabit Ethernet QSFP28 uplink module for EX4300-48MP and EX4300-48MP-S switches.
