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 EX4300-48T and EX4300-48P provide 48 built-in
10/100/1000BASE-T Ethernet network ports, with or without PoE+ depending on the
switch model, and four built-in quad small form-factor pluggable plus (QSFP+) ports
that can house 40-Gigabit QSFP+ transceivers. All network ports in the EX4300-48P
switch are equipped for Power over Ethernet (PoE+), whereas EX4300-48T has no PoE+
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+
