Whether there is a method used to replace an unprotected system control board rather than using jumpers

4

When replacing an unprotected system control board of a master subrack, you need to use its jumpers to clear the database in its system parameter area (by setting jumpers to 1010) and in its flash memory. This database clearance prevents the NE from becoming abnormal due to a residual database after the system control board is replaced. Database clearance can only be implemented by setting jumpers onsite and cannot be implemented using the NMS.
The database clearance script provided in the Downgrade Guide applies to scenarios in which the system control board is normally running. (The Downgrade Guide also applies to such scenarios in which the NE can be managed by the NMS). During system control board replacement, however, the new system control board has not been started and the NE cannot be managed yet. Therefore, commands in the database clearance script cannot be used.

Methods for setting battery jumpers on system control boards of SSE2SCC boards
Locate the battery jumper J1 on the E2SCC board. The pins of J1 are numbered 1, 2, and 3 from bottom to top. When the battery power supply is required (the board is in dry run mode or normal running mode), pins 1 and 2 need to be capped. When the battery power supply is not required (the board is placed at the warehouse), pins 2 and 3 need to be capped.

Methods used to recover services after the system control board is replaced on the OSN 1800
THE OSN 1800 does not support data downloading. Services can be recovered only by restoring database data.

Methods used to set the battery jumper on the SSE2SCC board
Locate the battery jumper J1 on the E2SCC board. The pins of J1 are numbered 1, 2, and 3 from bottom to top. When the battery power supply is required (the board is in trial running or normal running mode), pins 1 and 2 need to be capped. When the battery power supply is not required (the board is placed at the warehouse), pins 2 and 3 need to be capped.

Method to clear the parameter settings and database of the system control board in a slave subrack using jumpers or DIP switches
The method for clearing parameter settings and database data on the system control board in a slave subrack is the same as that in the master subrack. For details, see the related topic in the product documentation.

Method used to set the jumpers on the TN11AUX02 board of the OSN 6800
The J16, J15, J4, J3, and J2 jumpers can be set in 32 combinations, representing decimal values 0-31. The default setting of the five jumpers is 00000. The value 0 indicates the master subrack and the other values indicate slave subracks.
