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 Understanding EX Series Virtual Chassis. For
more information about VCFs, see “Virtual Chassis Fabric Overview” on page 2.
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+ uplink module (model number:
EX-UM-4X4SFP), which has four SFP+ ports that can house four SFP+ transceivers, four SFP transceivers,
or a combination of SFP and SFP+ transceivers in the four ports on the uplink module.
The 48-port EX4300 switches with multigigabit ports—EX4300-48MP and EX4300-48MP-S—provide 24
built-in 10/100/1000BASE-T Ethernet network ports, 24 built-in 100/1000/2500/5000/10000BASE-T
Ethernet network ports, and four built-in Virtual Chassis Ports (VCPs) that house 40-Gbps quad small
form-factor plus (QSFP+) transceivers. The 24 built-in 10/100/1000BASE-T Ethernet network ports
support 10 Mbps, 100 Mbps, and 1 Gbps speeds. The 24 built-in 100/1000/2500/5000/10000BASE-T
Ethernet network ports support 100 Mbps, 1 Gbps, 2.5 Gbps, 5 Gbps, and 10 Gbps speeds. All network
ports are equipped for PoE+ and provide up to 95 watts of power. The four VCPs can be used to connect
the switches to other devices in a Virtual Chassis configuration.
These switches support AC power supply with front-to-back airflow.
Each switch provides a slot for installing an optional 2-port 40-Gigabit Ethernet QSFP+/100-Gigabit
Ethernet QSFP28 uplink module (model number: EX-UM-2QSFP-MR) or a 4-port 1-Gigabit
Ethernet/10-Gigabit Ethernet SFP+ uplink module (model number: EX-UM-4SFPP-MR). The 2-port
