# 4 Getting Started

This chapter describes the following installation procedures for the cPCI-A3H20 carrier blade:

 2.5" U.2 NVMe drive (cPCI-A3H20/P only)
 M.2 M-Key NVMe module
 M.2 B-Key SATA module (cPCI-A3H20/M only)

# 4.1 cPCI-A3H20/P

# 2.5" U.2 NVMe Drive Installation

The cPCI-A3H20/P provides space to install a 2.5" U.2 NVMe drive. Install the drive to the bracket by inserting it into the U.2 connector and fastening the four screws provided as shown below.
