Network Port and Uplink Module Port LEDs in EX4500 Switches
Each network port and uplink module port on an EX4500 switch has two LEDs that
indicate link/activity and status. The figures in this topic show the location of these
LEDs:
■ Figure 7 on page 15 shows the location of the LEDs on the network ports on the
front panel of an EX4500 switch. The LEDs point toward the port to which the
LEDs belong.
■ Figure 8 on page 15 shows the location of the LEDs on the uplink module ports
on the SFP+ uplink module.
