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
wear the static-proof hand ring. If there is no hand ring, 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”.
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.
2.3.3 Cabinet Configuration
The following content assists you to make a proper cabinet configuration:

Each device on the cabinet gives off heat when it runs. Therefore, the sealed
cabinet must have the heat-discharge outlet and the cooling fan. Do not put
the devices too close, avoiding bad ventilation.
When you install the machine box at the open cabinet, prevent the frame of
the cabinet from blocking the airway of the machine box.
Ensure that nice ventilation is provided for the devices installed at the bottom
of the cabinet.
The clapboard separates exhaust gas and inflow air, and boost cool air to
flow in the machine box. The best location of the clapboard is decided by the
air flow mode in the machine box, which can be obtained through different
location tests.
2.3.4 Power Requirements
Make sure that the power supply has nice grounding and the power at the input
side of the switch is reliable. The voltage control can be installed if necessary. At
least a 240 V, 10A fuse or a breaker is provided in the phase line if you prepare the
short-circuit prevention measures for a building.
Caution:
If the power supply system does not have good grounding, or the input power
disturbs too much and excessive pulses exist, the error code rate of communication
devices increases and even the hardware system will be damaged.

Chapter 5 Hardware Fault Analysis
The part describes how to remove the fault from the switch.
5.1 Fault Separation
The key for resolving the systematic faults is to separate the fault from the system.
You can compare what the system is doing with what the system should do to
detect the fault. You need to check the following subsystems:
Power and cooling systems—power and fan
Port, cable and connection—ports on the front template of the switch and the
cables connecting these ports
5.1.1 Faults Relative with Power and Cooling System
Do the following checkups to help remove the fault:
When the power on-off is at the “ON” location, check whether the fan works
normally. If the fan does not work well, check the fan.
The working temperature of the switch is from 0 to 40 Celsius degrees. If the
switch is too hot, check whether the air outlet and air inlet are clean and then
do relative operations in section 2.3 “Requirements for Common Locations”.
If the switch cannot be started and the PWR indicator is off, check the power.
5.1.2 Faults Relative with Port, Cable and Connection
Do the following checkups to help remove the fault:
If the port of the switch cannot be linked, check whether the cable is correctly
connected and whether the peer connection is normal.
If the power on-off is at the “ON” location, check the power source and the
power cable.
If the console port does not work after the system is started up, check
whether the console port is set to a baud rate of 9600 bps, eight data bits, no
sum check bit, one stop bit and no traffic control.
