NOTE: If you have a Juniper J-Care service contract, register any addition,
change, or upgrade of hardware components at
https://www.juniper.net/customers/csc/management/updateinstallbase.jsp
Failure to do so can result in significant delays if you need replacement parts.
This note applies if you change the type of power supply or add a new type
of uplink module. It does not apply if you replace these components with the
same type of component.
Installing and Removing EX4500 Switch Hardware Components on page 121
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 10 on page 24 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 11 on page 25 shows the location of the LEDs on the uplink module ports on the
SFP+ uplink module.
