The SSN1EGS4 is a 4-port Gigabit Ethernet Switching Processing Board with Part Number03051249.The SSN1EGS4 is available in three functional versions, namely, N1, N3 and N4.
Here is the solution of the problem:
【Problem Summary】OSN3500 NE degrade fail（V1R10 > V1R9）
【Problem Details】OSN3500 use simulation package loading from V1R10C03SPC203 down V1R9SPC200, N4EGS4 board fails to start after activation, leading to activation of overtime

Some configuration of data board can not be smooth downgrade, so be sure to hard reset when downgrading re-initialize the configuration, even without updating the logical file also needs a hard reset.
【Resolution Details】There are two ways: 1) simulation package upgrade task to force load FPGA file, make a hard reset board downgrading; 2) after the downgrade failed hard reset using optp command once again, the specific command: optp: 8,0,1 b, 1 ,1,14,0 (first parameter is the board id, modify the corresponding hexadecimal value to other unchanged)When the data board downgrading requires a hard reset, or it may appear board not start properly.
