Only drill with the approval of the customer, contractor, and Huawei.
Remove interior cables before drilling holes into a cabinet.
Wear goggles when drilling holes to protect your eyes from metal shavings.
Wear protective gloves when drilling holes.
After drilling, clean up the metal shavings immediately to prevent them from entering
the cabinet.
When replacing a component, keep the component, screws, and tools at a safe place. If
any of them falls into running fans, the fans may be damaged.
When replacing a component near fans, do not insert your fingers or boards into the fans
unless the fans are switched off and stop running.
Choose railways, sea, or roads with good condition for transportation. Ensure that the
equipment is transported safely and securely. Excessive tilting or jolting during
transportation is not allowed. During transportation, the equipment must not be tilted
more than 15 degrees.
Only trained personnel are allowed to move the equipment.
Incorrect operations may cause excessive pressure, which may result in breakage or
exploration of the cooling system.
High-temperature and high-pressure components: compressor, refrigerant pipe.
To avoid frostbite caused by refrigerant leaks, take protective measures such as wearing
antifreeze gloves when handling refrigerant.
Low-temperature component: evaporator.
