C. Take proper measures to help persons who are hit by the disaster.
Artificial respiration is needed if necessary.
D. Seek for medical help, or judge the loss and seek for available help.

2.2.4 Electrostatic Discharge Damage Prevention

Electrostatic discharge may damage devices and circuits. Improper treatment may
cause the switch to malfunction completely or discontinuously.
Move or locate the devices according to the measures of electrostatic discharge
prevention, ensuring the machine box connects the ground. Another measure is to
correctly wear the static-proof wristband. If there is no wristband, use the metal clip
with the metal cable to clip the unpainted metal part of the machine box. In this case,
the static is discharged to the ground through the metal cable of the clip. You can
also discharge the static to the ground through your body.

2.3 Requirements for Common Locations

This part describes the requirements for the installation locations.

2.3.1 Environment

The switch can be installed on the desk or the cabinet. The location of the machine
box, cabinet planning and indoor cabling are very important for normal system's
function. Short distance between devices, bad ventilation and untouchable control
plate will cause maintenance problems, systematic faulty and breakdown.
For location planning and device locating, refer to section 2.3.2 "Location
Configuration Prevention". If the device crashes frequently or errors occur, this
preventive information can help you prevent the problem from recurring.

2.3.2 Location Configuration Prevention

The following preventive measures assist you to design the proper environment for
the switch.

Make sure that the workshop is well-ventilated, the heat of electrical devices
is well-discharged and sufficient air circulation is provided for device cooling.

Avoid to damage devices by following the electrostatic discharge prevention
procedure.

Put the machine box at the place where cool air can blow off the heat inside
the machine box. Make sure the machine box is sealed because the opened
machine box will reverse the cool air flow.
