Preparing for installation

Safety recommendations

To avoid any equipment damage or bodily injury caused by improper use, read the following safety
recommendations before installation. Note that the recommendations do not cover every possible
hazardous condition.

General safety recommendations

Keep the chassis clean and dust-free.
•
• Make sure that the ground is dry and flat and anti-slip measures are in place.
Do not place the switch in a moist area and avoid liquid surrounding the switch.
•
Keep the chassis and installation tools away from walk areas.
•
Do not wear loose clothing, jewelry (for example, necklace) or any other objects that could get
•
caught in the chassis when you install and maintain the switch.

Safety with electricity

Clear the work area of possible hazards, such as ungrounded power extension cables, missing
•
safety grounds, and wet floors.
Locate the emergency power-off switch in the room before installation. Shut the power off at once in
•
case any accident occurs.
Unplug all the external cables (including power cords) before moving the chassis.
•
• Do not work alone when the switch has power.
Always check that the power has been disconnected.
•

Safety with switch moving

To move a WX3024E switch:
Remove all the external cables (including the power cords) before moving the chassis.
•
Move the switch carefully.
•

ESD prevention

To prevent the electronic components from being damaged by the electrostatic discharge (ESD), take the
following precautions:
• Hold an interface card by its edges. Do not touch any electronic components or printed circuit.
Put an interface card into an antistatic bag.
•
• Make sure the switch is well grounded. For how to ground the switch, see the chapter "Installing the
switch (page 14)."
Always wear an ESD-preventive wrist strap when installing components.
