Ethernet ports and
four QSFP+ ports
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 Understanding
EX Series Virtual Chassis. For more information about VCFs, see
page 2.

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 (model number:
EX-UM-2QSFP) that can house two QSFP+ transceivers or an 8-port 10-Gigabit Ethernet SFP+ uplink
module (model number: EX-UM-8X8SFP) that can house eight SFP+ transceivers, eight SFP transceivers,
or a combination of SFP and SFP+ transceivers in the eight ports on the uplink module.
