NOTES:
All pins are numbered in ascending order from the left to the right, with side A on the top of the centerline and
side B on the bottom of the centerline, use the reference drawing in Fig2, with the logo visible.
The PCI Express interface pins PETpx, PETnx, PERpx, and PERnx are named with the following convention: “PE”
stands for PCI Express high speed, “T” for Transmitter, “R” for Receiver, “p” for positive (+) and “n” for negative (-).
The sequential mating for Hot-Plug is accomplished by staggering the edge fingers on the add-in card.
