What is chasModuleSerialNumber?

This object reports the serial number of the physical module in a given chassis location. An admin managing warranty claims or asset tracking pulls this value remotely to log exactly which physical unit is installed where, without needing to physically read a label buried in a rack. When filing an RMA for a failing line card, the admin would read chasModuleSerialNumber via SNMP to include the exact serial in the support ticket.
