The GX7016 is a 20-slot 6U PXI chassis that can accommodate up to 19 switching or instrument cards as well as a remote PXI bus interface such as the MXI-4. In addition to supporting all of the PXI-1 resources, the GX7016’s PXI backplane provides an internal, high performance, 16 wire, and analog bus via the backplane’s P5 connectors. Each of the GENASYS switching cards connects to this internal 16 wire bus, providing the ability to route signals from an external instrument to any of the receiver’s interface connections.
System power for the GX7016 is provided by a 755-watt power supply. Forced-air cooling for the chassis is provided by a four (4) 79 CFM fans mounted under the card cage—providing positive airflow per the PXI specification. This configuration provides the optimum cooling for the chassis regardless of the type or number of instruments or switch cards used. Additional cooling is provided for the system power supply. This cooling configuration, in conjunction with air plenums within the chassis, provides airflow for all module slots per the PXI specification and requires no additional rack space for inlet or outlet air.
The GX7016 chassis supports the monitoring of slot temperatures and system power supply voltages as well providing the ability to program or map each PXI trigger line from one PCI segment to another. In addition, the user can program the temperature monitoring function for specific warning and shutdown limits. All user specific setups can be stored in non-volatile memory as a user configuration and can be used as the default setup for normal chassis operation.
