Drive Enclosure Components

When replacing a component, you must know its part number and whether it is hot serviceable. Having that information helps you to order the correct replacement component and to determine whether you can replace the component yourself. To locate part numbers, open Oracle System Handbook (https://support.oracle.com/handbook_private/index.html). The part numbers are listed in the Oracle FS1 Flash Storage System components list.

The Drive Enclosure chassis is a field replaceable unit (FRU). The remaining components of both Drive Enclosure types are customer replaceable units (CRU). Drive Enclosure CRUs are hot serviceable.

WARNING: Do not power‑cycle a Drive Enclosure. Power‑cycling a Drive Enclosure impacts the primary and secondary data paths in the Drive Enclosure and puts user data at risk.

The following figure shows the CRUs in the DE2-24P Drive Enclosure.
