2.3. General Requirements for Location
This part discusses the requirements for the location of safe installation and use of the
system. Before installation, ensure that the location has been properly prepared.
2.3.1. Environment of the Location
By adoption of card-track installation method, EPON access device can be xed on DIN card
track. The equipment adopts fan-free design. Please note that installation environment
should be well-ventilated to facilitate equipment heat dispersion.
When planning location arrangement and equipment placement, please remember to
discuss the precautions as set forth in «Precautions for Allocation of the Location». If the
equipment often breaks down or error often occurs, such precaution information may help
you isolate failure and avoid recurrence of the problem.
2.3.2. Precautions for Allocation of the Location
Precautions listed below may help you design a suitable environment for EPON access
device to avoid system failure caused by the environment.
• Ensure air is well circulated and electrical equipment heat is well dispersed in the work
room. Air circulation must be sucient to provide a good cooling environment;
• Equipment should be better placed in such a way that cool air frequently passes by the
equipment. Ensure the outer casing of the equipment is complete and xed. If it is open,
air circulation inside the equipment will be damaged, which may interrupt airow or
change the direction of the cool air that should cool down heat-emitting the internal
elements.

2.3.3. Rack Configuration
The following content helps you design a suitable rack conguration.
• Each equipment on the rack will emit heat during working. To ensure good ventilation,
closed rack must be provided with heat dispersion port and cooling fan, and equipment
should be closely placed from each other;
• When installing equipment on the open rack, pay attention not to make the rack frame
obstruct the vent holes of EPON access device. Please carefully check the equipment
location after the equipment is installed to avoid such case.
• Ensure that eective ventilation measure has been provided for the equipment installed
at the lower part of the rack.
2.3.4. Power Supply Consideration
Check power supply. Ensure that power supply system is well grounded. Input voltage
range should be AC110V~240V. Too high voltage will damage the machine.
Warning:
If the power supply system is not well grounded, or input power uctuates greatly with excessive pulse, false code
rate of the communication equipment will increase, or even hardware system will be damaged!
2.4. Installation tools and equipment
Tools and equipment required for installation of A-GEAR P1004T EPON are not included in
standard conguration of A-GEAR P1004T EPON. User needs to prepare them by himself.
The following are typical tools and equipment required for installation of A-GEAR P1004T
EPON:
• Screw driver

5.1. Failure Isolation
The key to settle system failure is to isolate failure from the system. Failure isolation and
settlement becomes easy by comparison between what the system should do and what the
system is doing. The following sub-systems should be considered in solving the problems:
• Power connection;
• Port, cable and link - ports on the front panel of EPON access device and cables
connected to the ports.
5.1.1. Power failure
Check the following items to facilitate isolation of problems:
• Conrm that power cable is reliably connected and power is supplied.
• Check the environmental conditions. Note that temperature required for work location
of EPON access device should be -5°C ~ 45°C.

• If power supply is normal for a certain circuit of EPON access device, the power indicator
lamp Power should be lit, otherwise power supply for this circuit is abnormal. When the
system is normally registered on OLT, PON lamp should be lit and LOS lamp should be
o.
5.1.2. Failure in port, cable and link
Check the following items to facilitate isolation of problems:
• If EPON access device port cannot be linked, check if the link cable is correct and if
opposite terminal connection is normal or not.
