The uplink module in EX4500 switches is a hot-removable and hot-insertable
field-replaceable unit (FRU): You can remove and replace it without powering off the
switch or disrupting switch functions.
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 those ports.
