PCIe slots
The PowerEdge T640
offer
balanced, scalable I/O capabilities including integrated PCIe 3.0 expansion slots. It
offers
the capability of
accommodating full-height or half-height PCIe cards.
PCIe expansion slots
The PowerEdge T640 provides eight PCI Express expansion slots and one dedicated storage slot. The list below are the supported
slots for the T640:
•
Slot
-
1: one x16 PCIe Gen3 for FL/FH card from CPU1
•

-
9 (Internal PERC Slot): one x8 PCIe Gen3 for HL/FH card from CPU1
NOTE: Slots 4, 5, 6, 7, and 8 will only work with CPU2 populated.
PCIe slot restrictions
The list below are restrictions and population rules on the PCIe slots:
•
Dual width cards in slot 3, 6, and 8 obstructs slot 2, 5, and 7 respectively.
•
2 PCIe bridge cards consume slot 1, 3, for NVMe
configurations.
•
GPU are only allowed in slot 1, 3, 6, 8, two external fans are installed only (and required) for GPU ready
configurations.
If a GPU is
installed in slot 1, 3, Fan Ext R is blocking, no cards with external IO is allowed in slot 1~3.
•
If a GPU are installed in slot 6, 8, Fan Ext R and Ext L are blocking, no cards with external IO is allowed in slot 1~3, 5~8.
•
Only slot 4 will not be blocked by external fans and IO ports will be accessible.
