Installing Components 6.1 Installing Boards Installing an interface board Installing a main control board CAUTION Wear ESD wrist straps or ESD gloves before installing or removing a board. Filler panels must be installed in vacant slots to ensure good electromagnetic compatibility and meet dust-proof and heat dissipation requirements. - Page 12 Installing Components 6.2 Installing Optical Modules NOTICE Huawei-certified optical modules need to be used. This is because the reliability of non-Huawei-certified optical modules cannot be ensured, and using such modules may affect service stability. Wear ESD wrist straps or ESD gloves before installing optical modules.
