Page 31: Uplink Modules
The 32-port EX4300 switches provide two slots for installing an optional uplink module. You can either use the uplink module ports 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.
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 of EX4300 switches. You can operate these interconnected switches as a single, logical device with a single IP address.
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 pre-installed in the rear panel of the switches.
