Safety recommendations
To avoid equipment damage or bodily injury, 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.
• Ensure good ventilation at the installation site 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 power source voltage is as required.
• To avoid electrical shocks, do not open the chassis while the switch is operating or when the switch
is just powered off.
• To avoid ESD damage, wear an ESD wrist strap to hot-swap a power module.
Examining the installation site
The S5130-EI switches must be used indoors. You can mount your switch in a rack or on a workbench, but
make sure:
• Adequate clearance is reserved at the air inlet and exhaust vents for ventilation.
• The rack or workbench has a good ventilation system.
• The rack is sturdy enough to support the switch and its accessories.
• The rack or workbench is reliably grounded.
