Method used to determine whether database clearance starts or ends on the system control board for the OSN 8800/6800/3800

20

In versions earlier than the OSN 8800/6800/3800 V100R006C03, there is no indicator blinking. Therefore, you need to clear the database at a specific time. Specifically, insert the spare part into the original slot and wait 2 minutes so that the database clearance is complete.
For the OSN 8800/6800/3800 V100R006C03 and later versions, the STAT indicates the database clearance progress. To be specific, database clearance starts when the STAT indicator is quickly blinking green and ends when the STAT indicator is steady green.

Whether a system control board is required in an OSN 8800 platform subrack when it is used as a slave subrack
When an OSN 8800 platform subrack functions as a slave subrack, it does not require a system control board. Its IU17 and IU18 slots can be used to house service boards. When it functions as a master subrack, a system control board is required.

Way in which the indicator blinks when the database is being cleared during system control board replacement on the OSN 6800/8800
During system control board replacement, the DIP switches 1011 and 1010 are used to clear the database. V100R006C03 has a different indicator status from V100R006C01. The description in the Product Documentation for the OSN 6800/8800 V100R006C03 is as follows: Insert the spare SCC board in the slot housing the original SCC board. The database is being cleared when the STAT indicator on the SCC board is blinking quickly, and the database clearing is complete when the STAT indicator is steady green.
