3FE 51892 AAAA TCZZA Edition 01 ONT Product Information Manual
Temperature hardened ONTs can be installed in a closet, a terminal room, or outside 
the building on a wall or a pole. Alcatel-Lucent recommends using mounting 
hardware that is in compliance with GR-950 corrosion requirements.
Ensure that when pole mounting an ONT:
• any threaded, carbon steel hardware used should be zinc-plated per ASTM A 
153[9]
• any threaded, corrosion resistant (stainless) steel pad or pole mounting hardware 
used should be passivated to remove surface impurities
For information about UPS installation requirements, refer to the manufacturer’s 
documentation.
