HP D2220sb Storage Blade Maintenance and Service Guide

Removal and replacement procedures 28
CAUTION: To prevent improper cooling and thermal damage, do not operate the D2220sb or
the enclosure unless the first drive bay is populated with a drive, and drive bays 2 and 3 and all
device 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.
To remove the component:
1. Determine the status of the drives from the drive LED definitions (on page 47).
2. Back up all server data.
3. Open the drive drawer.
IMPORTANT: The drive drawer is not fully extended until the rail lock is engaged. To engage the
rail lock, extend the drive drawer approximately 2.54 cm (1 inch) past the initial resistance.
