CAUTION: Safety Instructions
Use the following safety guidelines to ensure your own personal safety and to help protect your system
and working environment from potential damage. For complete safety and regulatory information, see
the
Product Information Guide that shipped with your system. Warranty information might be included
in this document or as a separate document.
SAFETY: Rack Mounting of Systems
Observe the following precautions for rack stability and safety. Also refer to the rack installation
documentation accompanying the system and the rack for specific caution statements and procedures.
Systems are considered to be components in a rack. Thus, "component" refers to any system as well as
to various peripherals or supporting hardware.
CAUTION:
Before installing systems in a rack, install front and side stabilizers on stand-alone racks or the front
stabilizer on racks joined to other racks. Failure to install stabilizers accordingly before installing systems in a
rack could cause the rack to tip over, potentially resulting in bodily injury under certain circumstances.
Therefore, always install the stabilizer(s) before installing components in the rack.
CAUTION:
After installing system/components in a rack, never pull more than one component out of the rack on
its slide assemblies at one time. The weight of more than one extended component could cause the rack to tip
over and may result in serious injury.
NOTE:
Your system is safety-certified as a free-standing unit and as a component for use in a Dell rack cabinet
using the customer rack kit. The installation of your system and rack kit in any other rack cabinet has not been
approved by any safety agencies. It is your responsibility to ensure that the final combination of system and rack
complies with all applicable safety standards and local electric code requirements. Dell disclaims all liability and
warranties in connection with such combinations.
• System rack kits are intended to be installed in a rack by trained service technicians. If you install the
kit in any other rack, be sure that the rack meets the specifications of a Dell rack.
CAUTION:
Do not move racks by yourself. Due to the height and weight of the rack, a minimum of two people
should accomplish this task.
• Before working on the rack, make sure that the stabilizers are secured to the rack, extended to the floor,
and that the full weight of the rack rests on the floor. Install front and side stabilizers on a single rack
or front stabilizers for joined multiple racks before working on the rack.
• Always load the rack from the bottom up, and load the heaviest item in the rack first.
• Make sure that the rack is level and stable before extending a component from the rack.
• Use caution when pressing the component rail release latches and sliding a component into or out
of a rack; the slide rails can pinch your fingers.
• Do not overload the AC supply branch circuit that provides power to the rack. The total rack load
should not exceed 80 percent of the branch circuit rating.
• Ensure that proper airflow is provided to components in the rack.
• Do not step on or stand on any component when servicing other components in a rack.
