Module: COM21-HCXTOP-MIB
OID (symbolic): COM21-HCXTOP-MIB::hcxSerialNumber

Description: The Serial Number is a 32 character number used by COM21 to uniquely identify the device.
What is hcxSerialNumber?
This read-only 32-character DisplayString is the serial number COM21 uses to uniquely identify this ComController, notably longer than the 10-character format used for individual STUs. It's the reference an admin uses when opening a support case or RMA specifically for the headend chassis hardware. For example, when reporting a hardware fault on the headend itself rather than a subscriber's STU, support would quote hcxSerialNumber to identify the exact controller unit.
