Electrostatic Discharge Precautions
To ensure proper handling of system components and to prevent hardware faults caused
by electrostatic discharge, follow all safety precautions:
• Wear an anti-static wrist or ankle strap.
• Observe all standard electrostatic discharge precautions when handling plug-in
modules or components that have been removed from any anti-static packaging.
•
Avoid
contact with backplane components and module connectors.
Safety and Handling Precautions
To ensure safe handling and correct operation of the equipment, follow all the safety
precautions and instructions:
• Observe safe lifting practices. Each High-performance NAS Platform or each
storage array can weigh 66 lb. (30 kg) or more. It is important to note that at
least two people are
required
to handle and position them.
• A storage cabinet must be loaded correctly to prevent any serious injuries.
1. Place the Fibre Channel switches in the center of the storage cabinet. The recommended
rack unit positions are 23 and 24. The positions can be adjusted according to a specific
storage cabinet configuration.
2. Load and position the
High-performance NAS Platform
(s) directly above the Fibre
Channel switches.
3. The System Management Unit (SMU) should be placed directly below the Fibre Channel
switches.
4. The first storage enclosure should be positioned at the bottom of the storage cabinet.
Additional enclosures are then placed above existing enclosures, going towards the top of
the system cabinet.
5. Once the bottom half of the storage cabinet has been filled, the top half of the storage
cabinet can be filled. Begin by placing a storage component directly above the
High-
performance NAS Platform
and fill upwards.
Note:
All expansion cabinets including all storage enclosures, must be filled from the
bottom to the top.
Warning
:There is a risk that the cabinet could fall over suddenly. To prevent this
from occurring:
• Do not remove more than one unit at a time.
• Hitachi Data Systems recommends that the stabilizer plate be secured to
the front of the system cabinet. For more information, see " Attaching the
Stabilizer Plate to the System Cabinet ," on page 8.
