EX4500 switches support SFP+ uplink modules. The SFP+ uplink module is a
hot-insertable and hot-removable field replaceable unit (FRU).
NOTE: Uplink modules and transceivers are not part of the EX4500 switch's
shipping configuration. You must order them separately.
You can install up to two SFP+ uplink modules in an EX4500 switch. Both uplink modules
install horizontally on the front of the chassis. The uplink module slot on the left is PIC 1.
The uplink module slot on the right is PIC 2. See

Each SFP+ uplink module provides four ports. Each module can house four 10-gigabit
small form-factor pluggable (SFP+) transceivers or four 1-gigabit small form-factor
pluggable (SFP) transceivers.
NOTE: When a new uplink module is installed in the switch or an existing
uplink module is replaced with another uplink module, the switch detects
the newly installed uplink module. The switch creates the required interfaces
when new transceivers are installed in uplink module ports.
The operating mode for an SFP+ uplink module is shown in the output of the
pic fpc-slot slot number pic-slot 1
You can use the uplink module ports to connect an access switch to a distribution switch.
Figure 10 on page 26 shows the SFP+ uplink module.
