Modification of HDD Carrier for Use with Teledyne LeCroy U.2 Interposer
Warning
:
DO NOT OPERATE IN A CHASSIS WITHOUT ADDING CARRIER RAILS OR YOU WILL DAMAGE THE
INTERPOSER.
Teledyne LeCroy's PCI Express Gen4 x4 U.2/U.3 Single/Dual Port 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.
