1. If a cabinet is equipped with a single power supply unit (PSU-60B), a maximum of
56 station devices may be connected to that cabinet. However, if the cabinet is
equipped with two power supply units, a maximum of 120 station devices may be
connected to that cabinet.
See the configuration section of the General Description
Section for more details.
2. Do not connect devices with a total REN greater than 2.5 to any port on this card.
3. Do not connect devices with a total REN greater than 2.5 to this card.
