Workaround
The fix for this issue is to check the number of PCI Riser card assemblies installed in the server and make sure there is a PCI Riser card installed in connector 2.
Additional information
The root cause for this issue is a PCI Riser card assembly must be installed in connector 2, even if you do not have an option adapter to install.
To identify this issue, when the BRD LED is lit and all cooling zones are asserted at the same time, remove the server cover and check if PCI Riser card 2 LED is on.
