5. IftheFRUisinM3anddoesnothavepayloadpowergrantedtoit,theFRUmightbe
askingformorepowerthantheShMScangranttothatslot.Performthefollowingsteps:
a. CheckthemaximumpowerallowabletothatFRU'sslotbyreadingthe'MaxPower
CapabilitySensor',sensor0x1012,ontheFRU'sSlotResource.Checkhowmuch

maximumpowertheShMScanallowtothatslot,thatFRUcannotbeactivatedinthat
slot.
b. IfthisFRUisamanagedFRU(e.g.AMC),itsre questedpower,theparentFRU'spower,
andanyothermanagedFRUalreadyactivatedonthatparentFRUispossibly
exceedingthe
maximumpowercapabilityoftheparentFRU'sslot.
Forexample,aslotmightallowaMaximumof200W.ItalreadyhasanAMCCarrier
andanRTMwithpowerof120W(includingmanagementpower)and30W
respectively.Inthiscase150Wisalreadygrantedfromthatslot'smaximumbudget.
Nowif
anAMCisinstalled ontheAMCcarrierwithitsownrequirementof60Wthen
thetotalpowerbudgetofthatslotisex ceededandtheShMSwouldnotbeableto
