Data Security

•Before beginning product installation, power down your host computer and all attached peripheral devices.

•Disk drives 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 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.

•If you remove any drive module, you may lose data.

•If you remove a drive module, replace it immediately. Replace it with a drive module of the same type and capacity

•Do not abandon your backup routines. No system is completely foolproof.
