Introduction
Use this document for quick installation and setup.
Teledyne LeCroy’s PCI Express 5.0 U.2/U.3 Interposer provides a quick and simple means for protocol analysis of Solid
State Drives (SSDs) based on PCI Express (PCIe®) protocols. The U.2/U.3 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 T516 and Summit T54 and supports data rates
of 2.5 GT/s, 5.0 GT/s, 8.0 GT/s, 16.0 GT/s and 32 GT/s. The interposer supports side band signals such as PERST#,
WAKE#, CLKREQ# and SMBus (SMBCLK, SMBDAT). The interposer can be used with Single x4 Port or Dual x2 Ports.
It also supports U.2 and U.3 standards. It can be used also with Summit T4 and Summit M5x analyzers using a
conversion cable.

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.
SW2: Clock Select SW2: Clock Select
12PortB 34PortA
ON ON REFCLKA ON ON REFCLKA
OFF ON US_CLK OFF ON US_CLK
ON OFF DS_CLK ON OFF DS_CLK
OFF OFF REFCLKB OFF OFF REFCLKB
Note: If using direct cable from Summit T516 refer only to table for Cable A for ports A and B.
Note: All switches in the ON position for SW2 is the factory default.
REFCLKA: Use the reference clock from Port A in the U.2 host connector.
US_CLK: Use the reference clock from the corresponding MMCX connector.
DS_CLK: Use the reference clock from the corresponding MMCX connector.
REFCLKB: Use the reference clock from Port B in the U.2 host connector.

SW1: DUT Power Status LEDs
ON LED Connected (Default)
OFF LED Disconnected
Note: 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 SW1 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 a hard drive carrier are in Section 7.
Perform the following steps to connect the Interposer (see the image below):
1. Set the SW2 DIP switch to the desired positions to set the clock selection for Port A and Port B according to the table
above (see Section “3” on page ii).
2. Attach the interposer to a drive carrier (See Section “7” on page vi).
3. Install the U.2 or U.3 device under test (DUT) into the bay on the interposer as shown (will fit only 2.5” drives). 
Screw the drive to the bay to secure it.
4. Install the Interposer into the host system connector.
5. Connect the Summit T516 Analyzer (or other compatible Teledyne LeCroy analyzer) to the interposer using
the appropriate analyzer cable (PE028UCA-X Y-cable or PE027UCA-X straight cable). 
6. Connect the analyzer to a host computer system using the USB port on the front panel of the Summit analyzer.
7. If not already done, install the PCIe Protocol Analysis software on the host machine.
8. Connect 12V DC using the AC adapter supplied with the interposer to the Gen5 U.2/U.3 interposer. Make sure that
the AC adapter is powered on before proceeding to the next step.
9. Power on the analyzer.
10. Launch the PCIe Protocol Analysis application, setup the appropriate recording options and start a recording. 
For more information see the PCI Express Protocol Analysis Summit T5 Gen5 Analyzer User Manual -> 
Recording Options -> Select Interposer Type section.
11. Power on the host machine.
12. Use the PCIe Protocol Analysis application to monitor, record and view PCI Express traffic passing through 
the U.2 Interposer.

Modification of HDD Carrier for Use with the PCIe 5.0 U.2/U.3 Interposer
Warning: DO NOT OPERATE IN A CHASSIS WITHOUT ADDING CARRIER RAILS OR YOU WILL DAMAGE THE
INTERPOSER.
Teledyne LeCroy's PCI Express 5.0 U.2/U.3 Interposer 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 the
following figures.

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.

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.
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.
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 5.0 U.2/U.3 Interposer 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 interposer cable to 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.
