2. Connect your OM3/OM4 cables to the transceivers you plugged in as follows:
– Connect System 1, System Interconnect 1, port 49 to System 2, System Interconnect 1, port 51.
– Connect System 1, System Interconnect 2, port 49 to System 2, System Interconnect 2, port 51.
– Connect System 2, System Interconnect 1, port 49 to System 1, System Interconnect 1, port 51.
– Connect System 2, System Interconnect 2, port 49 to System 1, System Interconnect 2, port 51.

6.4 Cabling Three Systems
