A drive carrier assembly is composed of the drive or drive blank and a drive carrier, and are used to

provide for controlled insertion into, and extraction from, the storage enclosure. Drive carrier assemblies

are installed from the front of the enclosure, which simplifies service access. Closing the drive carrier

handle ensures complete seating of the connectors.

All 24 drive bays must be filled with drive carrier assemblies, each containing either a drive, or drive

blank, to ensure proper airflow and system cooling. The following figure provides a close-up view of a

drive carrier assembly housing an NVMe drive.

Figure 2. Displaying drive carrier assembly

Fully assembled drive carrier assembly with one of the following options exactly matches the other drives

that are installed in the same enclosure:

• Part number - 01LL727 3.84 TB 2.5" PCIe Gen4 NVMe Flash drive

• Part number - 01LL728 7.68 TB 2.5" PCIe Gen4 NVMe Flash drive

• Part number - 01LL729 15.36 TB 2.5" PCIe Gen4 NVMe Flash drive

• Part number - 01LL823 38 TB 2.5" Flash Core Module

Figure 3. Displaying NVMe drive replacement part

Refer to the following steps to remove and replace a faulty NVMe drive:

1. Confirm the failed drive location from the fault drive LED.

You can identify the failed drive by the amber fault LED on the drive carrier. If the fault LED is lit on a

drive, it is safe to replace the drive.

Alternatively, locate unhealthy drives in the management GUI, either from the Storage> Physical

Disks page as shown in Figure 4 on page 3, or from the list of events that are available under the

Monitoring > Events page.
