Uplink Modules

Optional uplink modules are available for EX4500 switches. Two uplink modules can
be installed in an EX4500 switch. Each uplink module provides four SFP+ ports for
connecting to core devices in a data center. You can install SFP or SFP+ transceivers
in these ports.

The EX4500 switch is available in two models—one with front-to-back airflow and
the other with back-to-front airflow. Table 1 on page 5 lists the two models for an
EX4500 switch and the components included in each model.
