IMPORTANT Copper based media ports: e.g., Twisted Pair (TP) Ethernet, USB,
RS232, RS422, RS485, DS1, DS3, Video Coax, etc. are intended connecting to intra-
building (inside plant) link segments, not subject to lightening transients or power
faults. Copper based media ports: e.g., Twisted Pair (TP) Ethernet, USB, RS232,
RS422, RS485, DS1, DS3, Video Coax, etc. are NOT for connecting inter-building
(outside plant) link segments that are subject to lightening transients or power faults.
Failure to observe this notice could result in damage to equipment.
