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 Figure 13 on page

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 show chassis pic fpc-slot
slot number pic-slot 1 command.
You can use the uplink module ports to connect an access switch to a distribution switch.
Figure 14 on page 50 shows the SFP+ uplink module.
