HP D2220sb Storage Blade Maintenance and Service Guide

Removal and replacement procedures 23
Remove the drives
Use this procedure to remove the drives when servicing other components. To replace a failed or broken
drive, see "Drive (on page 27)."
WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the
internal system components to cool before touching them.
CAUTION: To prevent damage to electrical components, properly ground the D2220sb before
beginning any installation procedure. Improper grounding can cause ESD.
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.
