General descr pt on.
he 720-800A base unit is the basic chassis of the Penta 720 Modular I/O audio router unit. It consists
of a 19” wide, 2U high sub rack, equipped with a basic I/O and router main board and a backplane to
accommodate a total of 8 I/O cards providing flexible and versatile I/O structure for various router and
I/O applications. he modular I/O cards are hot-swappable, and can be accessed by opening the front
plate of the unit. As standard the basic chassis is equipped with two fixed power supplies for redundant
power operation. A modular power supply bay is also available with two retractable power supply units.
he 720-800A base unit is quipped with two fans mounted in the front panel with sufficient airflow to
assure cooling of all electronics in the base unit. he fans adjust the speed depending on the
temperature inside the Penta 720. Since the unit is designed for machine room installation, the fans can
be quite noisy in high temperature environments.
he air inlet is on the front of the unit and the air exhaust is on that back of the unit. When mounted in a
rack make sure that the air can pass freely trough the unit. he Penta 720 facilitates supervisory circuitry
for all fans, voltages, and the internal temperature
Access ng the Penta 720 cards.
he Penta 720 cards mounted in the 720-800A base unit are accessed by opening the hinged front
panel of the unit. he front panel is opened by un screwing the two finger screws in both side of the unit.
he front panel can tilt down but is supported by hinges in both sides.
he up-to 8 Penta 720 I/O cards are placed vertically in the unit and can be removed by releasing the
rear panel screws and pulling at the front of the card. he cards support hot swop and can be pulled and
inserted in the frame while the unit is in operation.
For more details on the I/O cards please refer to the individual installation guides for these cards.
