Warning
Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if interconnections

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
