Important Safety information
CAUTION: Use extreme caution when installing and pulling units from the rack; they can slip
and fall, causing damage to the HP StoreOnce Backup system or injury. HP is not responsible for
any damage or injury caused by the mishandling of the HP StoreOnce Backup system.
Refer to your rack documentation for detailed safety instructions about working with units within
the rack and ensuring that the rack is stable.
WARNING! To reduce the risk of personal injury or damage to the equipment, ensure that only
one hard drive drawer is extended at a time.
When adding hard drives to the hard drive drawer, observe the following general guidelines:
• When the drawer is opened, the cooling fans in the enclosure will run at full-speed. This is
normal.
• Hard drives are sensitive to excessive vibration. Use care when opening and closing the
drawer.
• Never leave the drawer open for any length of time. It should be opened only for maintenance
and storage expansion.
• Verify that the drives are fully seated before closing the drawer.
• The drawer is fully closed when the fans slow down to their normal speed.
• The drawer should be closed with the handle in the released position.
NOTE: Remember to close the handle after closing the drawer
