Please note:
1. When four E9612 all-optical subracks are installed in a cabinet, that is, only optical-layer boards are installed in the four subracks, and only optical-layer boards are installed in the four subracks, no regeneration board or OTU board is installed, you are advised to set all E9612 subracks to the low-power mode to reduce power consumption.
2. The low-temperature mode is applicable to extreme scenarios, such as high altitude and extremely low-temperature environments, to improve board reliability. The common mode is used by default in all scenarios except the low-power consumption mode.
