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.
•
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 modules and fan trays, wear an ESD wrist strap to
avoid damaging the units.
Examining the installation site
The switch must be used indoors.
Mount your switch in a rack and verify the following items:
•
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.
To ensure correct operation and long service life of your switch, install it in an environment that meets
the requirements described in the following subsections.
