HP Z840 Workstation Series Service Manual

NOTE: It is normal for the expansion card retention clamp to have a slight (5-10 degree) angle when closed.
If the angle is greater than this, open the clamp and ensure that all cards are properly seated and all the
brackets are mated to the chassis, and then re-close the clamp.
