OS for EX Series Ethernet Switches, Release 10.3
One EX4200-24P switch (SWA-2) with 24 access ports, all of which support PoE
One uplink module with two 10-gigabit ports is installed in the EX4200-48P switch.
These ports can be configured as trunk ports to connect to a distribution switch or
customer edge (CE) router or as Virtual Chassis ports (VCPs) to interconnect with a
member switch that is located too far for dedicated VCP cabling. (The uplink module
ports on the SFP and SFP+ uplink modules and the SFP network interfaces on the
EX4200-24F switches can also be used for these purposes.) For information on
configuring the uplink ports as trunk ports to a distribution switch, see "Configuring
Gigabit Ethernet Interfaces (CLI Procedure)" on page 1153 or "Configuring Gigabit Ethernet
Interfaces (J-Web Procedure)" on page 1143. For information on configuring uplink ports
as Virtual Chassis ports, see "Setting an Uplink Module Port as a Virtual Chassis Port
(CLI Procedure)" on page 1023.
Table 146 on page 954 shows the configuration settings for the expanded Virtual Chassis.

Figure 17 on page 954 shows that the three member switches ( SWA-0, SWA-1 and SWA-2)
are interconnected with their dedicated VCPs on the rear panel. The LCD on the front
displays the member ID and role. SWA-0 also includes an uplink module. Its uplink ports
can be used to connect to a distribution switch.
