Furthermore, because this card relies completely on the master controller for communication links and configuration parameters, its onboard RS-232 port cannot be independently utilized for broad network mapping or logic modification. Ensure the onboard 1756-BA2 lithium battery cell is monitored regularly; low energy levels can corrupt clock operations during complete system power blackouts.\n\u003c\/p\u003e\n\n\u003ch3 style=\"color: #1a365d; border-bottom: 2px solid #2b6cb0; padding-bottom: 0.25rem; margin-top: 1.5rem; margin-bottom: 1rem;\"\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cdiv style=\"background-color: #fff5f5; border-left: 4px solid #c53030; padding: 1rem; margin-bottom: 1.5rem; color: #9b2c2c;\"\u003e\n  \u003cstrong\u003eCRITICAL WARNING:\u003c\/strong\u003e De-energize and lock out all main backplane paths and external auxiliary supply voltages before mounting or extracting the co-processor hardware.
