SUPERSERVER 6026TT-HD/D6 Series User's Manual
Due to the memory allocation to system devices, the amount of memory that
remains available for operational use will be reduced when 4 GB of RAM is used.
The reduction in memory availability is disproportional. Refer to the table below.

The 6026TT-HD/D6 series servers include two preinstalled riser cards designed

each node). These riser cards each support two (four total for the system) full-height,
full-length PCI Express x8 cards.

lowing steps to add a PCI add-on card:
1.
Remove the PCI slot shield on the chassis by releasing the locking tab.
2.
Insert the add-on card into the riser card.
3.
Secure the add-on card with the locking tab.
