##### FRU Paths (1 Running Processor Module)

The following figure shows the express module topology for a server with one running processor module installed, where the running processor module is installed in processor module slot 0 and a filler panel is installed in processor module slot 1.

In this scenario, the FRU path for express module slot 7 (EM7) follows this path, starting from the processor module:

1. Processor 0 in processor module 0, to

2. PCIe switch 0, to

3. Express module slot 7 (EM7)

In this scenario, the full FRU path for EM7 is:

`/pci@400/pci@1/pci@0/pci@6`

As a second example, the FRU path for express module slot 8 (EM8) follows this path, starting from the processor module:

1. Processor 1 in processor module 0, to

2. PCIe switch 1, to

3. Express module slot 8 (EM8)

In this scenario, the full FRU path for EM8 is:

`/pci@500/pci@1/pci@0/pci@1`
