The following system bus and OptiConnect informational SRCs are the most common OptiConnect network-related messages that are posted in the Product Activity Logs of systems in a cluster.
B600 69A8 Link Operational
This informational SRC indicates that a fiber-optic link has become operational again. The satellite system will post the message. This is normally seen after reconnecting the redundant link cable.
B600 69C1 Loss of Contact With the Remote System
This informational SRC indicates that a remote system in an OptiConnect network has been brought down, or has crashed. To prevent this SRC during normal shutdown of a system in the cluster, run an ENDSBS QSOC *IMMED before bringing the system down.
B600 69D8 Link Non-operational
This informational SRC indicates that the fiber-optic link between two systems has become non-operational. Pulling a fiber-optic cable will result in this SRC. Since the OptiConnect hardware provides for redundant links, the hardware will switch over to the other fiber-optic link and continue to operate both buses on the one remaining cable.
During a Hub system power up, this SRC may occur during initial program load prior to completion and can be ignored.
