When we test OSN1800 II compact chassis before delivery, but we cannot login OSN1800 II, it shows wrong account. After consult our engineer, that it need to set DIP switch and jumpers on TNF1SCC or TNF3SCC board.
This article will describe how to set DIP switch and jumpers.
DIP Switch and Jumpers
Figure 1 and Figure 2 show the positions of the DIP switch and jumpers on the SCC board.
Figure 3 Position of the DIP switch on the TNF3SCC board
The hardware configuration of the SCC board can be implemented through a four-bit DIP switch SW1 on the SCC board. See Figure 3 and Table 1.

States and functions of SW1 DIP switch
|Value||DIP Switch Setting||Function Description|
|0||0000||When the value is 0, the SCC board runs with the watchdog enabled.|
|1||0001||When the value is 1, 2, or 3, the SCC board is in debugging state.
When the SCC board is in debugging state with the watchdog disabled, the BIOS is running and the NE software is not started.
|4||0100||When the value is 4, the SCC board runs with the hardware watchdog disabled.|
|5||0101||When the value is 5, the SCC board runs in BIOS state and the IP address is always 126.96.36.199. In addition, the NE software is not started.|
|6||0110||When the value is 6, the SCC board is in demonstration state. In this state, indicators on the board blink, the BIOS is running and the NE software is not started.|
|7||0111||The value 7 is reserved. When the value is 7, or 8, the SCC board runs with the hardware dog enabled.|
|8||1000||When the value is 8, the SCC board copies databases in the CF card or data in the system parameter area to the flash memory.|
|9||1001||When the value is 9, the chassis works in non-master/slave mode.|
|10||1010||Erases the system parameter areas.|
|11||1011||When the value is 11, the SCC board deletes the NE database.|
|12||1100||When the value is 12, the SCC board deletes the NE software including the patch software.|
|13||1101||When the value is 13, the SCC board deletes the NE database and the NE software including the patch software.|
|14||1110||When the value is 14, the SCC board erases all the contents in the flash memory.|
|15||1111||When the value is 15, the SCC board deletes all the data in the flash memory except the board manufacturing information. The data includes the system data, system parameter areas, and extended BIOS data.|
By default, the factory DIP switch setting is 0000. The SCC board is normal state and the DIP switch setting does not need to be changed unless otherwise required.
Every time you change the DIP switch setting, perform a power-off reset on the SCC board to validate the new setting.
After the board completes the operation specified by setting the BIOS DIP switch to a specific value, clear the DIP switch setting (that is, set the DIP switch to binary value 0000) before restarting the board; otherwise, the board cannot enter the normal running state.
Jumpers are present on the SCC board and are preset at factory. You do not need to change the jumper setting.
- J8 and J9 are used to specify whether the equipment is powered by a -48 V or -60 V power source. When pins 1 and 2 are capped, the power supply is -48 V, when no pin is capped, the power supply is -60 V.
- J48 is used to specify whether the EEPROM, which saves the board manufacturing information, is write-protected. When pins 2 and 3 are capped, the EEPROM is write-protected; when pins 1 and 2 are capped, the EEPROM is not write-protected.
- If pins 1 and 2 of J51 are capped, it indicates that the SCC board is intended for the global market.
