Remove the PCIe Riser From PCIe Slots 3 and 4
This PCIe riser is actually installed in PCIe slot 3, but it supports an M.2
mezzanine and up to two PCIe cards. The upper slot, referred to as slot 3, can
be used for any supported PCIe card, and, therefore, is optionally populated.
The lower slot, referred to as slot 4, is dedicated to the internal HBA card,
and, therefore is always populated. The internal HBA card is a field replaceable
unit (FRU). For instructions for servicing the internal HBA card, see Servicing the Internal HBA Card and HBA Super Capacitor (FRU)
