• All supplied plug-in modules and blanking plates must be in place to
complete the internal circuitry and enable air to flow correctly around an
enclosure.
• Using the system for more than a few minutes with modules or blanking
plates missing can cause an enclosure to overheat, leading to power
failure and data loss. Such use may invalidate the warranty.
• A loss of data can occur if a hard drive module is removed. Immediately
replace any modules that are removed. If a module is faulty, replace it
with one of the same type, of at least the same capacity and speed.
• Always shut down the system before it is moved, switched off, or reset.
• All storage enclosures are fitted with optical SFP transceivers. The
transceivers that are approved for use with supported storage enclosures
vary depending on the unit. The transceivers qualified for older systems
might not be approved for use with the most current storage systems. To
ensure proper operation of the server and the storage subsystems, use
only the approved replacement parts for each system. Contact the Hitachi
Data Systems Support Center for technical details about replacement
parts.
• Maintain backup routines. Do not abandon backup routines. No system is
completely foolproof.
