Data Security
• Power down your host computer and all attached peripheral devices before beginning installation.
• Each enclosure contains up to 12 removable disk drive modules. Disk units are fragile. Handle them with care,
and keep them away from strong magnetic fields.
• All the supplied plug-in modules and blanking plates must be in place for the air to flow correctly around the
enclosure and also to complete the internal circuitry.
• If the subsystem is used with modules or blanking plates missing for more than a few minutes, the enclosure
can overheat, causing power failure and data loss. Such use may also invalidate the warranty.
• If you remove any drive module, you may lose data.
– 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
• Ensure that all disk drives are removed from the enclosure before attempting to manhandle or move the rack
installation.
• Do not abandon your backup routines. No system is completely foolproof.
