What is acSysModulePresence?

This OID indicates whether a module is physically present in its slot or missing, using integer values for present or not-present states. Network teams use this to detect hardware removal or failure before it causes service interruption. For example, a value of 1 means the module is present and healthy, while 0 means the slot is empty or the module failed.
