EX4300 switches also provide uplink ports and a slot for installing an optional uplink module. You can manage EX4300 switches by using the same interfaces that you use for managing other devices running Juniper Networks Junos operating system (Junos OS)—the CLI, the J-Web graphical interface, and Junos Space.

Page 31: Uplink Modules
EX4300 switches provide one slot for installing an optional uplink module. You can use the uplink module ports either to connect the switch to other devices or configure these ports as VCPs and use them to interconnect EX4300 switches to form a Virtual Chassis or a VCF configuration by using SFP+ transceivers.
Page 32: Virtual Chassis
“Uplink Modules in EX4300 Switches” on page Virtual Chassis You can interconnect a maximum of 10 EX4300 switches to form a Virtual Chassis. You can operate these interconnected switches as a single, logical device with a single IP address. You can use the following ports to configure an EX4300 switch in a Virtual Chassis:...
Page 33: Power Supplies
By default, the built-in QSFP+ ports are configured as VCPs. Power Supplies EX4300 switches support AC or DC power supplies with different airflow directions. Power supplies for the EX4300 switch are fully redundant, load-sharing, and hot-removable and hot-insertable FRUs. All the EX4300 switch models except EX4300-24T-S, EX4300-24P-S, EX4300-32F-S, EX4300-48T-S, and EX4300-48P-S switches are shipped with one power supply preinstalled in the rear panel of the switches.

Page 208 To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect the EX4300 switch to earth ground before you connect it to power. For installations that require a separate grounding conductor to the chassis, use the protective earthing terminal on the switch chassis to connect to the earth ground.

QFX3600 (leaf) QFX3500 (leaf) EX4300 (leaf) Although best practice is to use QFX5100 switches in the VCF, you can use EX4300 switches as leaf devices. Installations with combinations of QFX5100-48T, QFX3600, QFX3500, and EX4300 as leaf devices in the VCF are called mixed mode. All VCF installations can support 20 total devices, of which 4 QFX5100 devices can be configured into spine devices.
Page 221: Connecting Qfx Series And Ex Series Switches In A Qfx Virtual Chassis
In a QFX Virtual Chassis, you can connect up to 10 standalone QFX5100, QFX3600, QFX3500, and EX4300 switches into a QFX Series Virtual Chassis and manage the interconnected switches as a single chassis. Unlike a Virtual Chassis Fabric (VCF), which is cabled in a spine and leaf topology, the QFX Virtual Chassis is cabled in a ring topology.
Page 222: Before You Start
On QFX5100, non-channelized QSFP+ uplink interfaces. All fixed SFP+ interfaces on the QFX5100-96S switches are also available. On EX4300, non-channelized QSFP+ interfaces; Ports 0 and 1 are configured as VCP by default. All fixed SFP+ interfaces can also be configured.
Page 223: Cabling Qfx3500 Switches In A Qfx Virtual Chassis
QFX5100 switches in these roles whenever possible. An all EX4300 member is simply considered an EX4300 Virtual Chassis. See Understanding EX4300 Virtual Chassis. If the QSFP+ interfaces are not available for VCP, 10-Gigbit interfaces can be used.
