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 16 on page 52 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 17 on page 52 shows the location of the LEDs on the uplink module ports on the SFP+ uplink
module.
