2.6 Chassis Cascade
The FRM220 chassis may be cascaded in such a manner that only one single IP address is required to manage
up to 10 chassis in a single location. The connection diagram is shown below. Each chassis is assigned a unique ID
starting at zero for the master chassis and incrementing for each cascaded chassis, up to an ID of nine. The "out" of
the parent chassis connects to the "in" of the child using any standard UTP cable with RJ-45 connectors.
