“Read theinstallationGuidelines” onpage 126“Power offthe server forthis task” onpage 194“ATTENTION:Static Sensitive DeviceGround package before opening”on page 127Note:Your server supports three types of 2.5-inch-drive backplanes: SATA/SAS 8-bay backplane (eight SATA/SASdrive bays), AnyBay 8-bay backplane (four SATA/SAS drive bays and four NVMe drive bays), and NVMe 8-bay backplane. Depending on the backplane type and quantity, the installation location of the backplanesvaries.• One backplaneAlways install either the SATA/SAS 8-bay backplane or the AnyBay 8-bay backplane to drive bays 0–7.• Two backplanes– Two SATA/SAS 8-bay backplanes, two AnyBay 8-bay backplanes, or two NVMe 8-bay backplanes:install the two backplanes to drive bays 0–7 and drive bays 8–15– One SATA/SAS 8-bay backplane and one AnyBay 8-bay backplane: install the AnyBay 8-baybackplane to drive bays 0–7; install the SATA/SAS 8-bay backplane to drive bays 8–15• Three backplanes– Three SATA/SAS 8-bay backplanes, three AnyBay 8-bay backplanes, or three NVMe 8-baybackplanes: install the three backplanes to drive bays 0–7, drive bays 8–15, and drive bays 16–23– Two SATA/SAS 8-bay backplanes and one AnyBay 8-bay backplane: install the AnyBay 8-baybackplane to drive bays 0–7; install the two SATA/SAS 8-bay backplanes to drive bays 8–15 and drivebays 16–23– Two AnyBay 8-bay backplanes and one SATA/SAS 8-bay backplane: install the two AnyBay 8-baybackplanes to drive bays 0–7 and drive bays 8–15; install the SATA/SAS 8-bay backplanes to drivebays 16–23– Two NVMe 8-bay backplanes and one SATA/SAS 8-bay backplane: install the two NVMe 8-baybackplanes to drive bays 0–7 and drive bays 8–15; install the SATA/SAS 8-bay backplanes to drivebays 16–23Before installing the 2.5-inch-drive backplane, touch the static-protective package that contains the newbackplane to any unpainted surface on the outside of the server. Then, take the new backplane out of thepackage and place it on a static-protective surface.To install the 2.5-inch-drive backplane, complete the following steps:Note: Depending on the specific type, the connectors on your backplane might look different from theillustration in this topic.Watch the procedure.
