2 Installing disk enclosures in the expansion rack
Before you begin
Read the following warnings and cautions before installing the disk enclosure.
CAUTION:
1. Make sure that the cabinet and all equipment mounted in the cabinet have a reliable ground
connection. Verify that the total current of the cabinet components does not exceed the current
rating of the power distribution unit or the power distribution modules.
2. Parts can be damaged by electrostatic discharge. User proper anti-static protection. For
additional information, see the documentation that shipped with your system.
Rack stability
Rack stability protects personnel and equipment.
WARNING! To reduce the risk of personal injury or damage to equipment:
• Extend leveling jacks to the floor.
• Ensure that the full weight of the rack rests on the leveling jacks.
• Install stabilizing feet on the rack.
• In multiple-rack installations, fasten racks together securely.
• Extend only one rack component at a time. Racks can become unstable if more than one
component is extended.
Make sure that the rack is sufficiently stable. If provided, lower the rack leveler feet and make
sure any stabilizers are installed. If provided, extend the rack anti-tip device. Failure to extend
the anti-tip device could result in personal injury or damage if the rack tips over.
