Installation Guide

Installation instructions (rear port solution)

Note: Due to differences in chassis design, portions of this installation procedure will vary

depending on the type of workstation you have (P520c, P520, P720, or P920). Where necessary,

the installation procedure differences are noted below.

1. Lay the workstation down on its side and remove the side access cover – this will facilitate

access to the motherboard. If you are working with a P920, remove the air baffle from the

middle of the chassis.

2. Install the Thunderbolt 3 PCIe x4 card in the appropriate slot, as designated by the

following table:

P520c: PCIe slot 4

P520: PCIe slot 6

P720: Primary choice: PCIe slot 2; Secondary choice: slot 1

P920: Primary choice: PCIe slot 2; Secondary choice: slot 4

3. Connect the GPIO cable between the connector on the front of the adapter card and the

motherboard. The motherboard connector location varies across the four workstations

covered in this guide, but it is in the general vicinity of the SATA connectors and looks like

this:

4. Replace the workstation side access cover and latch it into place. Note – if you are

working with a P920, don’t forget to first replace the air baffle and then replace the side

cover.
