Method to clear the parameter settings and database of the system control board in a slave subrack using jumpers or DIP switches

16

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 jumpers and DIP switches on the SCC board
The battery jumpers on the SCC board maintain the configurations of the board in case of a power failure. If the SCC board is in use, cap the battery jumpers to make a short circuit, which enables the battery to supply power normally. The BIOS jumpers and DIP switches help clear the board parameter area and database on the SCC board.

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.

Method used to clear the NE database of the system control board in OTN equipment
Set the jumper on the system control board to 1011.

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.

Processing of the LAN_LOC alarm reported by the AUX board in a slave subrack
The handling suggestions are as follows: 1. If network cables are normal, check whether the network port related to the alarm needs to be used. 2. If the network port does not need to be used but has been falsely configured as used, choose Communication > Access Control in the NE Explorer. On the page that is displayed, set the ETH/NMETH port to disabled. 3. If the alarm persists, the AUX board may be faulty. When this occurs, replace the AUX board.
