IBM 2943 Manual page 36

v Systems with one processor chip module unit support up to two 5802 or 5877 expansion units. The
system has only one GX adapter supported.
v Systems with two processor chip module units support up to four 5802 or 5877 expansion units, that is,
two per GX channel adapter.
8202-E4B or 8205-E6B:
v If you install feature code 5610 or 5685 in the system, you cannot install the 5615 or EJ04, expansion
unit, and any I/O expansion drawers. This results in a total of eight internal slots.
v If you do not install feature code 5610 or 5685 in the system, a total of four internal slots are available
and you can install an I/O expansion unit.
8202-E4C, 8202-E4D, 8205-E6C, or 8205-E6D:
v If you install the feature code 5685 in the system, only one 5615 or EJ04 unit can be installed and
results in a total of ten internal slots.
v If you do not install feature code 5685 in the system, a total of six internal slots are available.
PCI, PCI-X, and PCIe adapters
Use this information to identify slot placement priorities in the system and the maximum number of
adapters that can be installed in the system and attached expansion units. Verify whether the adapter is
supported for your system. For details about the supported adapters, see "Supported PCI adapters for
the 8202-E4B, 8202-E4C, 8202-E4D, 8205-E6B, 8205-E6C, or 8205-E6D" on page 1.
FCs 5767, 5768, and 9055 are the only adapters that can be installed in slot 6 (P1-C7). If a GX adapter is
installed in GX++ slot 2 (P1-C8), FCs 5767, 5768, and 9055 must be installed in the other PCIe x8 slot.
