Uplink Modules - Juniper QFX5110 Series Hardware Documentation

In EX4300-48MP and EX4300-48MP-S switches, you can use only the built-in QSFP+ ports as VCPs to
connect the switch in a Virtual Chassis. You cannot configure the ports on the uplink module in
EX4300-48MP and EX4300-48MP-S switches to Virtual Chassis ports (VCPs). You cannot configure the
built-in QSFP+ ports as network ports.
NOTE: EX4300-48MP switches can be a part of an EX4300 Virtual Chassis with other EX4300
switches only. If you want to create a Virtual Chassis comprising EX4300-48MP switch and other
EX4300 switches, you must connect it to a 40-Gbps port on the other EX4300 switches in the
Virtual Chassis configuration. In a Virtual Chassis configuration comprising EX4300-48MP
switches, EX4300 switches can be configured only in the line card role.

about VCFs, see "Virtual Chassis Fabric Overview" on page

Uplink Modules

EX4300 switches provide one slot for installing an optional uplink module. You can use the uplink module
ports to connect the switch to other devices. You can also configure these ports on EX4300 switches
except EX4300-48MP and EX4300-48MP-S switches as VCPs and use them to interconnect EX4300
switches to form a Virtual Chassis or a VCF configuration by using SFP+ transceivers.
NOTE: You cannot configure the ports on the uplink module in EX4300-48MP and
EX4300-48MP-S switches as Virtual Chassis ports (VCPs).
