E nvi ron m e n t of t h e Lo c at io n
By adoption of card-track installation method, EPON access device can be fixed 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.
P re c a u t io ns fo r A l l oc at io n of t he Lo c atio n
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 sufficient 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 fixed. If it is open,
air circulation inside the equipment will be damaged, which may interrupt airflow or
change the direction of the cool air that should cool down heat-emitting the internal
elements.
