Virtual Chassis Control Interface (VCCI) Modules in an XRE200 External
Routing Engine
Virtual Chassis Control Interface (VCCI) modules provide Virtual Chassis ports (VCPs) within an EX8200
Virtual Chassis.
The 4-port 10/100/100BASE-T RJ-45 VCCI modules are used to connect the XRE200 External Routing
Engine to EX8200 switches to form an EX8200 Virtual Chassis. The VCPs are also used to connect XRE200
External Routing Engines together to provide a backup external Routing Engine for an EX8200 Virtual
Chassis. See Figure 14 on page 42

The 4-port 1000BASE-X GbE SFP VCCI module is used to connect two XRE200 External Routing Engines
in the same EX8200 Virtual Chassis together. You can use the SFP ports to connect XRE200 External
Routing Engines over distances up to 43.5 miles (70 km). You can also use the SFP VCPs to connect an
XRE200 External Routing Engine to an EX8200 switch within a Virtual Chassis only if an intermediary
switch is used. The intermediary switch is required because the management (MGMT) port on the Routing
Engine (RE) modules or Switch Fabric and Routing Engine (SRE) modules of an EX8200 switch do not
support SFP connections. See Understanding Long-Distance Virtual Chassis Port Configuration for an EX8200
Virtual Chassis for additional information on long-distance EX8200 VCP connections. See
Figure 15 on page 42 for an illustration of the 4-port 1000BASE-X GbE SFP VCCI module.

Each VCCI module can be installed in one of the two VCCI slots on the front panel of the XRE200 External
Routing Engine. The XRE200 External Routing Engine supports up to two VCCI modules and any combination
