SYSTEM MONITOR BOARD
The PCIe2-2711 system has an optional System Monitor board. It
has the same outline and profile as a
x1 PCI Express add-in card but it is not, it has a proprietary pin out and should be installed ONLY in
slot J9 of the PCIe-460. As it’s name suggests, the System Monitor board watches the operation of the
cooling fans, temperature at multiple board locations and the voltage of power supply rails and locally
created voltages on the expansion board.
The monitor board has an ethernet port allowing the expansion chassis to be placed on a network where
users can then remotely check expansion system status.
