as member ID 8 or 9 before connecting to a Virtual Chassis, it will not work until one of
these member IDs is configured.
The master and backup roles for XRE200 External Routing Engines are determined by
external Routing Engine uptime; the external Routing Engine that has been up the longest
is selected for the master role. The role has no correlation to member ID; a master or
backup XRE200 External Routing Engine can be member ID 8 or 9.

The roles of Virtual Chassis members in an EX8200 Virtual Chassis are defined by uptime
and hardware type. The XRE200 External Routing Engine with the most uptime assumes
the master role; the external Routing Engine with less uptime assumes the backup role.
EX8200 member switches are always in the linecard role.
