4) Do not work alone if potential dangers exist.
5) Cut off the power before checkout.
6) If trouble happens, take the following measures: A. Cut off the system's power.
B. Alarm.
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.
Electrostatic Discharge Damage Prevention
Electrostatic discharge may damage devices and circuits. Improper treatment may cause
the router to malfunction completely or discontinuously.
Move or locate the devicesaccording to the measures of electrostatic discharge prevention,
ensuring the machine box connectsthe ground. Another measureis to wear the static-proof
hand ring. If there is no hand ring, use the metal clip with the metal cable to clip the
unpaintedmetal 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 router 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 router.
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:

Chapter 5 Hardware Fault Analysis
The part describes how to remove the fault from the router.
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——power, cable；
Port, cable and connection—ports on the front template of the router 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 router is from 0 to 40 Celsius degrees. If the
router 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 router 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 router 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.
