●
Before installing, operating, or maintaining a cabinet, clean up any water, ice,
snow, or other sundries on the top of the cabinet to prevent sundries from
falling into the cabinet when you open the cabinet door.
●
Do not install, use, or operate outdoor equipment and cables (including but
not limited to moving equipment, operating equipment and cables, inserting
connectors to or removing connectors from signal ports connected to outdoor
facilities, working at heights, and performing outdoor installation) in harsh
weather conditions such as lightning, rain, snow, and level 6 or stronger wind.
●
Before handling a conductor surface or terminal, measure the contact point
voltage and ensure that there is no risk of electric shock.
●
Ensure that all slots are installed with boards or filler panels. Avoid hazards
caused by hazardous voltages or energy on boards. Ensure that the air
channel is normal, control electromagnetic interference, and prevent dust and
other sundries on the backplane, baseplate, and boards.
●
After installing the equipment, remove idle packing materials such as cartons,
foam, plastics, and cable ties from the equipment area.
●
In the case of a fire, immediately leave the building or the equipment area,
and turn on the fire alarm bell or make an emergency call. Do not enter the
building on fire in any case.
●
Do not stop using protective devices. Pay attention to the warnings, cautions,
and related precautionary measures in this document and on the equipment.
Promptly replace warning labels that have worn out.
●
Keep irrelevant people away from the equipment. Only operators are allowed
to access the equipment.
●
All cable holes should be sealed. Seal the used cable holes with firestop putty.
Seal the unused cable holes with the caps delivered with the cabinet. The
following figure shows the criteria for correct sealing with firestop putty.
