NOTE: OCP shroud are required for all drive configurations, even if the OCP card is not installed.
NOTE: DIMM blanks are required for CPU TDP>185 W, but are not required for CPU TDP<=185 W.
NOTE: GPU blank is required at GPU riser slot 2, when a GPU>75 W is installed at GPU riser slot 1.
NOTE: HDD blanks are required for empty HDD slots.
NOTE: *x5 and x7 fan count is applicable only for TBU configuration. Systems without TBU should not use x5 and x7 fan
counts. For TBU configuration, ambient temperature is < 35C.
NOTE: When GPU is selected, HPR fan must be required.
NOTE: GPU>75W must require fan redundancy (Fan quantity = 6 or 8).
NOTE: GPU>75 W does not support TBU.
NOTE: STD fans can also be upgraded to HPR fans.
