During initialization, the system mode is determined as follows: The router scans slot 1, 3, 5, and 7 in
sequence; when the first HIC is found, the router determines the system working mode according to the
card type; in the successive scanning, if the router finds that an HIC in a slot breaks the card mixture rule,
the slot is marked as ABNORMAL and is not initialized.
During hot swapping, the system mode is determined as follows: The router detects whether the type of
card that is inserted into slot 1, 3, 5, or 7 conflicts with the current system mode; if yes, the slot is
marked as ABNORMAL and is not initialized.
