Note that the recommendations do not cover every possiblehazardous condition.• Before cleaning the switch, remove all power cords from the switch. Do not clean the switchwith a wet cloth or liquid.• Do not place the switch near water or in a damp environment. Prevent water or moisture fromentering the switch chassis.• Do not place the switch on an unstable case or desk. The switch might be severely damaged incase of a fall.• Ensure good ventilation of the equipment room and keep the air inlet and outlet vents of theswitch free of obstruction.• Connect the yellow-green protection grounding cable before power-on.• Make sure the operating voltage is in the required range.• To avoid electrical shocks, do not open the chassis while the switch is operating or when theswitch is just powered off.• When replacing field replaceable units (FRUs), including expansion cards, power modules, andfan trays, wear an ESD wrist strap to avoid damaging the units.Examining the installation siteThe switch must be used indoors. You can mount your switch in a rack or on a workbench, but makesure:• Adequate clearance is reserved at the air inlet and outlet vents for ventilation.• The rack or workbench has a good ventilation system.• Identify the hot aisle and cold aisle at the installation site, and make sure ambient air flows intothe switch from the cold aisle and exhausts to the hot aisle.• Identify the airflow designs of neighboring devices, and prevent hot air flowing out of theneighboring device from entering the device.• The rack is sturdy enough to support the switch and its accessories.• The rack or workbench is reliably grounded.
