Removal and replacement procedures 27
CAUTION: To prevent improper cooling and thermal damage, do not operate the D2220sb or
the enclosure unless all enclosure device bays and the first three storage drive bays are populated
with either a component or a blank.
CAUTION: Thermal regulation is maintained only when the drive drawer is closed. The drive
drawer open alarm is triggered under the following conditions:
• A slow beep and flash (1 every 5 seconds) indicate that the drive drawer is open. The drives
are not fully protected by system air flow.
• A fast beep and flash (2 per second)—To avoid drive damage or data loss and storage blade
shutdown, close the drive drawer immediately.
When the drives reach critical temperatures, the system shuts down.

2. Remove the drive blank.
To replace the component, reverse the removal procedure.
