Warning
Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if
interconnections are made using uninsulated exposed metal contacts, conductors, or
terminals. Avoid using such interconnection methods, unless the exposed metal parts
are located within a restricted access location and users and service people who are
authorized within the restricted access location are made aware of the hazard. A
restricted access area can be accessed only through the use of a special tool, lock and
key or other means of security. Statement 1072
