View OCS Diags

The View OCS Diags Sub-Menu displays up to 10 System Diagnostics, all of which are not

editable. The

Net Errors, Network State, Network ID and Dup Net ID System Diagnostics only appear for QX751

models that have a BPxx attached.

The first two System Diagnostics are critical. If any of them indicate a Fault condition, the QX751will not

enter or remain in Run mode, and the problem must be investigated and corrected.
