Data security
Precautions can help preserve data security.
v Power down your host computer and all attached peripheral devices before beginning installation.
v Each enclosure contains up to 84 removable disk drive modules. Disk drives are fragile. Handle them
with care, and keep them away from strong magnetic fields.
v All the supplied plug-in modules must be in place for the air to flow correctly around the enclosure
and also to complete the internal circuitry.
v If the enclosure system is used with missing modules for more than a few minutes, the enclosure can
overheat, causing power failure and data loss. Such use can also invalidate the warranty.
v
If you remove a drive module, replace it immediately. If it is faulty, replace it with a drive module of
the same type and capacity.
v Ensure that all disk drives are removed from the enclosure before attempting to manhandle or move
the rack installation.
v Do not abandon your backup routines.
