Caution: Use caution when removing an IOM on which you have optional PoE installed to avoid
damaging the PoE module.
Precaución: Tenga cuidado al retirar un IOM que tenga un módulo PoE instalado, ya que éste
puede dañarse.
Note: The two power supplies in the G-Series have automatic voltage sensing that allows
connection to power sources ranging from 100–125 Vac, 12 A or 200–240 Vac, 7A,
50/60
Hz.
Note: To take advantage of the load sharing and redundancy capabilities, each power cord must be
plugged into a separate dedicated AC outlet.
Display Status
