PCI Express® Gen3 x2 U.2 Dual Port 12 Inch Interposer with SMBus Support User Manual and Quick Start Guide
1 Introduction Use this document for quick installation and setup. Teledyne LeCroy’s PCI Express Gen3 x2 U.2 Dual Port 12 Inch Interposer with SMBus Support provides a quick and simple means for protocol analysis of Solid State Drives (SSDs) based on PCI Express (PCIe®) protocols. The U.2 Interposer Card, used with a Summit Protocol Analyzer, enables PCIe bus traffic between a host backplane and SSD device to be monitored, captured, and recorded for protocol analysis. The card is compatible with the Summit T3-16, Summit T3-8, Summit T34, Summit T28 and Summit T24 and supports data rates of 2.5 GT/s, 5.0 GT/s and 8.0 GT/s. The interposer supports side band signals such as PERST#, WAKE#, CLKREQ# and SMBus (SMBCLK, SMBDAT).

Inspect the received shipping container for any damage. Unpack the container and account for each of the system components listed on the accompanying packing list. Visually inspect each component for absence of damage. In the event of damage, notify the shipper and Teledyne LeCroy. Retain all shipping materials for shipper’s inspection.
3 Clock Selection The source for the reference clock used by the analyzer to record PCI Express traffic is configurable according to below table. DIP switches and tables for clock selection are located on the rear side of the interposer. SW1: Clock Select 1

Switch Configuration
This switch connects the DUT power Indication LED to the bus power. It is located on the rear side of the interposer near SW1 and SW2. DUT Power LED Status on Interposer SW7: DUT Power LED ON

LED Disconnected
Note: This switch connects the DUT power indication LEDs to the bus power. In some systems with Hot-Plug management the Power Indication LEDs on the interposer may prevent the host system from turning ON bus power to the device, if this happens disconnect the LEDs using SW7 to allow proper bus power operation.

Connections
IMPORTANT:
If you plan to insert the interposer into a Chassis backplane you MUST fit the rails from a donor carrier to the interposer before use to avoid serious damage to the interposer. Instructions for Modifying the HDD Carrier are in Section 5.
Perform the following steps to connect the Interposer (see the image below): 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13.
Set the SW1 DIP switch to the desired positions to set the clock selection for Port A according to the table shown below. Set the SW2 DIP switch to the desired positions to set the clock selection for Port B according to the table shown below. Install the U.2 device under test (DUT) into the bay on the interposer as shown (will fit only 2.5” drives). For best results, attach the interposer to a drive carrier (See Section “7” on page iii). You may optionally secure the drive to the interposer using four screws on the sides of the DUT bracket. Connect the Summit T3-8 Analyzer (or other compatible Teledyne LeCroy analyzer) to the interposer using the system iPass cable. Connect the analyzer to a host computer system using the USB port on the front panel of the Summit analyzer. If not already done, install the PCIe Protocol Analysis on the host machine. Connect 12V DC using the AC adapter supplied with the interposer. (Make sure that the AC adapter is powered on). Power on the analyzer. Power on the host machine. Install the Interposer into the host system connector. Launch the PCIe Protocol Analysis application to monitor, record and view PCI Express traffic passing through the U.2 Interposer.
Note: For step 12, if testing for hot plug, run recording first from the PCIe Protocol Analysis then install the interposer into the host system connector.

Modification of HDD Carrier for Use with Teledyne LeCroy U.2 Interposer Teledyne LeCroy's PCI Express Gen3 U.2 Standard and Dual Port 12 Inch Interposers with SMBus support can be attached to a donor drive carrier.If you plan to insert the interposer into a Chassis backplane you MUST fit the rails from a donor carrier to the interposer before use, to avoid serious damage to the interposer. In order to do this, some adjustments need to be made to the drive carrier to allow the interposer to fit properly. Teledyne LeCroy provides these instructions as a service to users but any modification done to the drive carrier is done at the user’s risk. Teledyne LeCroy provides no guarantee or warranty with these modifications. These modifications of the drive carrier are the sole responsibility of the user. This procedure is for this specific drive carrier. Other drive carriers may need slightly different steps, but this drive carrier is typical. See figure on next page.
Drive Carrier Ejection Catch Assembly
Step 1. Remove the Drive Carrier from the Server Backplane To remove the drive carrier from the server backplane, squeeze the two levers together on the front of the carrier and while gripping the handle provided on the front of the carrier slowly pull the drive carrier out of the server backplane. Set the drive carrier on a suitable work surface (workbench with ESD pad or similar surface).
Step 2. Remove the Ejection Catch Assembly from the Drive Carrier To remove the ejection catch assembly, remove two screws holding the metal housing to the ejector catch assembly on the front of the drive carrier.

Bottom Screw
Step 3. Remove the Side Runners and Light Pipes from the Drive Carrier To remove the side runners and light pipes from the drive carrier, slide the black plastic runners towards the back and lift away from the retaining lugs. Retain the black plastic runners for reuse.
Step 4. Remove the Corner of the Side Rail After Removal from Drive Carrier Using a suitable cutting tool (diagonal cutting pliers, etc) remove the corners of the side rails. Cut along the corner of the side rail
Typical set of diagonal cutting pliers (or similar tool)
Step 5. Remove the EMI Shield Springs The EMI spring system should be gently pulled away and unclipped from the end of the drive carrier. It will not be reused.
Step 6. Bend Drive Carrier Ears Out of the Way The drive carrier is usually a simple folded piece of fairly thin metal, which can be gently bent flat by hand. If there are metal ears, which held the screws to the ejection catch assembly, they should be gently (by hand) unfolded first before the end of the drive carrier metal is unfolded. Ear bent out of the way
Step 7. Bend Drive Carrier Metal End Out Flat Gently (by hand) bend the metal end of the drive carrier out flat.
Step 8. Re-Attach the Plastic Side Rails After the Side Rail corners have been removed, the side rails can be reattached using the original screws.
Step 9. Attach the PCI Express Gen3 x2 U.2 Dual Port 12 Inch Interposer with SMBus Support to the Drive Carrier Slide the Interposer into the drive carrier, using the original mounting screws to hold it in place. The Interposer should be aligned with the same holes the drive carrier would have used. Note: Screw type for use with Drive Carrier: Metric screw, size M3, maximum length: 8mm.
Step 10. Attach Cabling to the Interposer Insert the carrier with the Interposer into the desired backplane slot. Plug one end of the iPass cable into the end of the Interposer and other end into the analyzer. Attach the 12VDC power and optional clock cables. This completes the assembly of the Interposer into the Drive Carrier.
8 Support Bracket: 3.5 Inch Conversion To support and stabilize the PCI Express Gen3 x2 U.2 Dual Port 12 Inch Interposer with SMBus Support within a 3.5" drive carrier, Teledyne LeCroy supplies a bracket kit. The bracket can be mounted on either the top or bottom of the Interposer, depending on the drive carrier configuration. Teledyne LeCroy’s interposer with the 3.5 inch bracket attached is shown below.
To install the bracket on either side of the Interposer, three screws are provided. 1. Set out the Interposer, bracket and mounting screws as shown below:
Zoom in on Screw-Bracket-Interposer
2. Using a small Phillips head screw driver insert each screw through the appropriate hole in the bracket. 3. Insert each screw into a threaded hole in the Interposer. 4. Tighten each screw so that the bracket is held firmly to the top or bottom of the Interposer (as shown below).
