Installing an NVMe SSD expander module
Guidelines
A riser card in a compute module is required when you install an NVMe SSD expander module.
An NVMe SSD expander module is required only when NVMe drives are installed. For configurations
that require an NVMe expander module, see "Drive configurations and numbering."
Procedure
The procedure is the same for installing a 4-port NVMe SSD expander module and an 8-port NVMe
SSD expander module. This section uses a 4-port NVMe SSD expander module as an example.
To install an NVMe SSD expander module:
1.
Power off the server. For more information, see " Powering off the server ."
2.
Remove the security bezel, if any. For more information, see " Replacing the security bezel ."
3.
Remove the compute module. For more information, see " Removing a compute module ."
4.
Remove the compute module access panel. For more information, see " Replacing a compute
module access panel ."
5.
Remove the high mid air baffle. For more information, see " Replacing air baffles in a compute
module ."
6.
Install the low mid air baffle. For more information, see " Installing the low mid air baffle or GPU
module air baffle to a compute module ."
7.
Connect the four NVMe data cables to the NVMe SSD expander module, as shown in Figure
6-37 .
Make sure you connect the ports on the module with the correct NVMe data cable. For more
information, see "
Connecting drive cables ."

8.
Install the NVMe SSD expander module to the compute module by using a riser card. For more
information, see "
Installing riser cards and PCIe modules ."
9.
Connect the NVMe data cables to the drive backplane. For more information, see " Connecting
drive cables in compute modules ."
Make sure you connect the ports on the drive backplane with the correct NVMe data cable. For
more information, see "
Connecting drive cables ."
10.
Install the compute module access panel. For more information, see " Replacing a compute
module access panel ."
11.
Install the compute module. For more information, see " Installing a compute module ."
12.
Install the removed security bezel. For more information, see " Installing the security bezel ."
13.
Connect the power cord. For more information, see " Connecting the power cord ."
