3 System Management & Configuration
The PXES-2780 chassis provides advanced system monitoring
and control. Chassis conditions, including internal temperature,
fan speed, and DC voltage can all be monitored on the system
controller or remote PC.
The PXES-2780 provides software configurable trigger bus
bridges, whereby the user can set the status of each trigger bus
line as shown in Figure 1-13. The PXES-2780 backplane can also
be configured between 4link x 4 and 2link x 8 by the configurable
PCIe switch fabric.
Communication with the chassis monitoring control unit is avail-
able using an embedded controller, such as the ADLINK PXIe-
3975, to access the smbus located on the system slot (1st slot), or,
alternatively, using a remote PC to communicate via the RS-232
serial port (D-SUB9 connector on the rear panel).
Please note that the RS-232 serial port can only monitor chassis
status, but does not provide the capability to change the trigger
bus bridges and PCIe switch fabric settings. Function comparison
between the smbus interface and RS-232 serial port is as follows.

RS-232 Serial Port
