If a display device contains displays for both maintenance and operations personnel, then the maintenance displays should have a separate location in the display network.
Additional Information:
Maintenance displays should not be located within the same part of the display network as operational displays because their presence may interfere with the ability of operators to promptly access operational displays. Displays used by maintenance personnel generally should not be accessible by operational personnel, unless operators need them to perform their tasks. Access to maintenance displays should be protected by passwords, key locks, or similar measures.
