If the cards need to be replaced during normal operation, the following guidelines
should be followed:
Hot-remove the the card to be repleaced. the master control board will
display a message of “pull out”,and the card status becomes destroyed.
Insert the new card. the master control board will display a message of
“push in”.After the card run nomally,the master control board will display the
link state of the card’s port.
Note:
Active Master control board can not be removed online.
3.5 Configuration Restoration Rules
When the switch starts up, the system will reload the information saved in the
“StartUp-Config” configuration file from the FLASH. If the card in slot N mismatches the
card type saved in “StartUp-Config”, then the configuration for that card will not be
reloaded.
When the system is operating normally and a user removes a card, the system
keeps all the information configured for that card but won’t write to FLASH, the
information will be lost upon system restart.
When the system is operating normally and the user hot-inserts a card into a slot
with a different card inserted previously, the system will not reload configuration; if the
slot has a same type of card as the one inserted previously, then the system will try to
reload the saved card’s configuration; if the saved card’s configuration is empty, the slot
configuration information recorded in "StartUp-Config" configuration file will be loaded.
3.6 Active-Standby Alternation
The switch supports Active-Standby alternation, i.e., when master management
cards are present and working normally, the user can switch the master control board
role between Active Master and Standby Master. The “show slot” command can be used
to determine the Active Master, non-Active master is the Standby Master. When
performing Active-Standby alternation, the user should press the SWAP button of Active
Master and remove the board, or just remove the Active Master directly, the Standby
Master will then become Active Master. After Active-Standby alternation, the configuration
of the switch will revert to the configuration saved in “startup-config”.
