You can use the built-in QSFP+ ports as network ports or as VCPs to connect the switch
in a Virtual Chassis or a VCF. By default, the built-in QSFP+ ports are configured as VCPs.
You can also use the uplink module ports to connect members of a Virtual Chassis or a
VCF across multiple wiring closets by configuring these ports as VCPs. For more
information about Virtual Chassis, see EX Series Virtual Chassis Overview. For more
information about VCFs, see Virtual Chassis Fabric Overview.

48-Port EX4300 Switches

The 48-port EX4300 switches provide 48 built-in 10/100/1000BASE-T Ethernet network
ports, with or without PoE+ depending on the switch model, and four built-in QSFP+
ports. These switches support AC or DC power supply with different airflow directions.
Each switch provides a slot for installing an optional 4-port 10-Gigabit Ethernet SFP+
uplink module, which has four SFP+ ports that can house four SFP+ transceivers, four
SFP transceivers, or a combination of four SFP+ and SFP transceivers.
