NOTE: Dell PCIe SSDs must be used with PCIe SSD backplanes. Do not plug in
SAS/SATA devices to a PCIe SSD backplane or vice versa.
Backplane Firmware Version
The backplane firmware version is reported in the Information Configuration
page of the PCIe SSD sub system.
NOTE: The firmware version is the only Backplane property supported for PCIe
SSD.
