Safety recommendations
To avoid any equipment damage or bodily injury caused by incorrect use, read the following safety
recommendations before installation. Note that the recommendations do not cover every possible
hazardous condition.
• Before cleaning the switch, remove all power cords from the switch. Do not clean the switch with wet
cloth or liquid.
• Do not place the switch near water or in a damp environment. Prevent water or moisture from
entering the switch chassis.
• Do not place the switch on an unstable case or desk. The switch might be severely damaged in case
of a fall.
• Ensure good ventilation of the equipment room and keep the air inlet and outlet vents of the switch
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 the switch
is just powered off.
• When replacing FRUs, including power supplies, fan trays, and interface modules, wear an ESD
wrist strap to avoid damaging the units.
Examining the installation site
The switch must be used indoors.
You can mount your switch in a rack. To rack-mount your switch, make sure the following requirements are
met:
• Adequate clearance is reserved at the air inlet and outlet vents for ventilation.
• The rack has a good ventilation system.
• Identify the hot aisle and cold aisle at the installation site, and make sure ambient air flows into the
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 the bottom
device from entering the top device.
• The rack is sturdy enough to support the switch and its accessories.
• The rack is reliably grounded.
