A pair of PCIe EMs is assigned to each server module in the chassis. All PCIe EMs connect to a chassis midplane. The midplane provides an interconnect between the server modules and the PCIe EMs installed in the chassis. The midplane connections between the server module and the PCI EM are logically defined by the midplane.
If the amber Service Action Required indicator on a PCIe EM is lit, this indicates a problem with the PCIe EM.
