The buildings lightning protectors must be verified as follow:
1.Check the lightning protectors, at the trunk cable entry point to the building housing the Avaya IP Office, paying special attention to the lightning protection grounding. Report any problems, in writing, to the telephone company.
2.Equipment that is designed to be connected using internal wiring is typically not lightning protected. Hence, Avaya IP Office extension cabling must not leave the building. For installations where telephones and/or other standard (tip/ring) devices are installed in another building then lightning protection is required (see Out of Building Telephone Installations).
The shock hazard symbol is intended to alert personnel to electrical hazard or equipment damage. The following precautions must also be observed when installing telephone equipment:
1.Never install telephone wiring during a lightning storm.
2.Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
3.Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.
4.Always use caution when working with telephone lines.
