Identifying Hardware Location String
The Windows Device Manager reports the hardware location in the following format:
CBHSS = value
where value is a numeric string that starting from the left indicates the cabinet number, bay
number, chassis number, and two-digit slot number. For example, CBHSS = 81107 indicates
cabinet 8, bay 1, chassis 1, and slot 07.
NOTE: The Windows OS does not show leading 0s. For example, if CBHSS = 1107 is displayed,
it denotes cabinet 0, bay 1, chassis 1, and slot 7.
