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.
Do not use water, alcohol, oil, or other solvents to clean electrical components inside and
outside a cabinet.
Personal Safety
If there is a probability of personal injury or equipment damage during operations on the
equipment, immediately stop the operations, report the case to the supervisor, and take
feasible protective measures.
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to
telecommunication network voltage (TNV) circuits.
Do not power on the equipment before it is installed or confirmed by professionals.
