Replace the cover

replacing the top cover” on page 28.
Removing a drive
You can remove a faulty drive from a 5U expansion enclosure to replace it with a new one received from
FRU stock.
Before you begin
Ensure that the drive is not a spare or a member of an array. The drive status is shown in Pools > Internal
Storage in the management GUI. If the drive is a member of an array, follow the fix procedures in the
management GUI. The fix procedures minimize the risk of losing data or access to data; the procedures
also manage the system's use of the drive.
Important: You can remove a drive assembly without powering off the expansion enclosure. However, to
maintain operating temperature, complete the following tasks.
• Do not remove a faulty drive assembly until its replacement is ready to be installed.
• Do not keep the cover off an operational enclosure for more than 15 minutes. The reduction in airflow
through the enclosure might cause the enclosure or its components to shut down to protect from
overheating.
About this task
The 5U expansion enclosure supports 92 drives. Figure 81 on page 83 shows an example of a drive
assembly.
