You can use the QSFP+ ports as network ports or as Virtual Chassis ports (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 the 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.
32-Port EX4300 Switches
The 32-port EX4300 switches—EX4300-32F and EX4300-32F-DC—provide 32 built-in
1-Gigabit Ethernet small form-factor pluggable (SFP) network ports that can house SFP
transceivers, four built-in 10-Gigabit Ethernet small form-factor pluggable plus (SFP+)
ports that can house SFP+ and SFP transceivers, and two built-in quad small form-factor
pluggable plus (QSFP+) ports that can house 40-Gigabit QSFP+ transceivers. They
support power supply and fan module with front-to-back airflow direction and have a
slot for installing an optional uplink module—a 2-port 40-Gigabit Ethernet QSFP+ uplink
module that can house two QSFP+ transceivers or an 8-port 10-Gigabit Ethernet SFP+
uplink module that can house eight SFP+ transceivers, eight SFP transceivers, or a
combination of eight SFP+ and SFP transceivers.
