Thunderbolt Setup and Configuration

Thunderbolt overview

Thunderbolt is one of the fastest input/output (I/O) protocols for connecting peripheral devices to your workstation. Your ThinkStation supports two different solutions for adding Thunderbolt 3 (P520, P520c, P720, P920) or Thunderbolt 4 (P350/P360 Tiny) ports: a two port front panel accessible solution and a rear single port solution. This document contains a brief description of Thunderbolt features, followed by detailed instructions for installing the Thunderbolt solutions in your computer.
Thunderbolt is an I/O interface that provides high speed data transfer between your workstation and peripheral devices. Thunderbolt can transfer data, monitor signals, and networking traffic through a simple, industry standard port. Thunderbolt employs the mechanically symmetrical USB Type-C connector, allowing for easy insertion regardless of plug orientation.
Through the use of the USB Type-C port, a Thunderbolt connection functions similar to a typical USB port. Like previous versions of USB, Thunderbolt ports can be used to connect memory keys, external hard drives, and other devices for the portable transfer of data. Unlike previous versions of USB, however, Thunderbolt supports multiple protocols for transferring data and connecting peripheral devices, including USB (all versions), Firewire, Ethernet, and Display Port (with HDMI, DVI, and VGA support by extension).

Installation instructions (front 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.
FLEX module preparation

1. The FLEX module is designed with the removable access cover on the bottom. Invert the FLEX module so that the removable cover is facing up and then place it on a flat work surface. Lift the metal tab on the rear of the module and slide the cover back and up to remove it from the module.

2. When viewed from the front, the FLEX module faceplate has slots for 4 devices or ports. The Thunderbolt 3 ports will be installed in the top right slot (with the module oriented as shown below), which is currently filled by a blank bezel. Remove the blank bezel by pressing the two internal retaining tabs and popping the bezel out the front of the faceplate.

3. Install the Thunderbolt 3 bezel in the empty faceplate slot. The bezel should be oriented so that the Thunderbolt 3 icons are below the port openings in its current orientation. The module will be flipped over before it is inserted into the workstation, so these icons will be above the ports in the final orientation. Press the bezel from the front until the retaining tabs snap into place.

4. Remove the card retaining bracket from the FLEX module by lifting the retention clip slightly and sliding the bracket toward the rear of the module.

5. Install the Thunderbolt I/O adapter card onto the retaining bracket by aligning the four locator holes with the corresponding mounting posts on the bracket. Press down on the card until the four retaining clips snap into place, securely mating the two parts into a single assembly.

6. Install the retaining bracket/adapter card assembly into the FLEX module by reversing the procedure performed in step 4. Slide the assembly forward until the retention clip snaps into place.

7. Plug four cables into the rear of the adapter card. The power cable is already part of the FLEX module and the remaining 3 cables were supplied with the Thunderbolt 3 kit. Use the following connector layout diagram as a guide for cable connections:a – Power cable connector
   b – GPIO cable connector
   c – Internal DP to DP cable connector
   d – mini-SAS cable connector
   Note: The power cable is integrated into the FLEX module, originating from the rear power connector. The other 3 cables are supplied as part of the Thunderbolt 3 kit.

8. Route the three cables through the cutout on the rear of the FLEX module and replace the cover. Starting from the rear of the module, engage the cover and slide it forward until it clicks into place.

FLEX module and adapter card installation
Prepare the workstation for FLEX module installation by removing the side access cover. Though not necessary, the rest of the installation will be easiest if the workstation is laid on its side at this point.

1. Remove the plastic filler blank and the EMI shield from the 5.25” FLEX bay you intend to use.
   P520c
   Remove the front bezel by releasing the three plastic tabs and rotating the bezel away from the chassis.Use the finger cutouts to pull the EMI shield out of the bay. There is an optical drive retainer on the side of the ODD/FLEX bay cage – remove this retainer and install it on the left side of the FLEX module as shown here:
   P520, P720, P920
   Press the release button to remove the plastic cover from the front of the FLEX bay, and then remove the EMI shield.

2. Insert the FLEX module, cover down, into the 5.25” FLEX bay that you have just prepared. Feed the GPIO, internal DP to DP, and mini-SAS cables through the bay as you insert the module and help to guide them around any obstacles from the inside of the workstation. Insert the module into the FLEX bay until it latches into place. The FLEX bay latching mechanisms vary across the various workstations, as follows:
   P520c
   The FLEX module should slide freely all the way into the bay until it latches into place.
   P520
   Slide the FLEX module into the bay until it stops, then press tab 1 as shown below and push the module further until it latches into place.
   P720
   Press the tabs toward each other as shown below and slide the module halfway into the bay. Release the tabs and continue sliding the module in until it latches into place. P920
   Remove the large air baffle from the chassis to gain full access to the inside of the workstation. Insert the FLEX module into the bay and push it until it latches into place.

3. Connect the SATA signal and power cables to the connector on the rear of the FLEX module.

4. 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

5. Route and connect the 3 cables that extend from the rear of the FLEX module
   Cable routing: this will vary depending on the particular workstation and the currently installed system components. However, typically the cables should be routed from the rear of the FLEX module toward the bottom of the workstation, passing directly behind the front system fan, to an area near the PCIe slots.
   Cable connections:
   – GPIO cable: connected to a black, 5-pin connector that is located along the bottom edge of the motherboard (when viewed from the side of the workstation). The precise 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: – DP to DP and mini-SAS cables: connected to the front of the PCIe x4 card as indicated below:

6. Installation of internal components is now complete, so replace the workstation’s side access cover. Note – if you are working with a P920, don’t forget to first replace the air baffle and then replace the side cover.

7. The PCIe x4 card must now be connected to your graphics adapter with the external DP to DP cable. If your graphics adapter only has miniDP ports, you will need a miniDP to DP adapter to complete this connection. Depending on the graphics adapter being used and the slot locations of the adapters, the connection should look like this:

8. Reconnect all peripheral devices, connect the power cable, and power on the workstation. Enter the BIOS Setup utility by pressing the F1 key while the Lenovo splash screen is displayed. Refer to the BIOS Configuration section at the end of this document for instructions on enabling and configuring Thunderbolt 3 in BIOS.
