Elected" on page 898. Therefore, we recommend that you start by powering on only one
member switch, the one that you want to function as the master.
NOTE: We recommend that you use the
save any configuration changes that you make to a multimember Virtual
Chassis.
The Virtual Chassis configuration provides networking access for 50 onsite workers, who
are sitting within range of a single wiring closet. The workers all use personal computers
and VoIP phones. As the office grows, you can add more EX4200 switches to meet
increased needs for access ports.
The topology for this example consists of two switches, one of which contains an uplink
module:
One EX4200-48P switch (SWA-0) with 48 access ports, all of which support PoE
One EX4200-24T switch (SWA-1) with 24 access ports, including eight ports that
support PoE
One XFP uplink module, with two 10–Gigabit Ethernet ports, is installed in the
EX4200-48P switch
Table 147 on page 919 shows the default configuration settings for the two-member Virtual
Chassis.

Figure 16 on page 919 shows that SWA-0 and SWA-1 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.
