4. Module Configuration
4.1. PCI Express Configuration Switch (SW1)
Switch SW1 allows you to configure the PCI Express x16 lanes from the CPU as 1 PCIe x16, 2 PCIe x8, or 1 PCIe x8 + 2 PCIe x4.
Mode Pin 1 Pin 2
1 PCIe x8 + 2 PCIe x4 On On
Reserved On Off
2 x8 PCI Express Off On
1 x16 PCI Express (Default) Off Off
4.2. PCIe x16-to-two-x8 Adapter Card
The Express-IB can be used with the PCIe x16-to-two-x8 Adapter Card on the Express-BASE6 Reference Carrier to support bifurbication of
the CPU's PEG interface (PCIe x16). The card reroutes the PCIe x16 to two x8 and allows testing of two independent PCIe add-on cards
with x8/x4/x2/x1 width. To use the card, set SW1 to "2 x8 PCI Express" as above.
