Safety: Rack Mounting Of Systems - Dell PC2216 Getting Started Manual

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:
over, potentially resulting in bodily injury under certain circumstances. Therefore, always install the stabilizers
before installing components in the rack. 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:
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.
• After a component is inserted into the rack, carefully extend the rail into a locking position, and then slide the
component into the rack.
• 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.
SAFETY: Modems, Telecommunications, or Local Area Network Options
• Do not connect or use a modem during a lightning storm. There may be a risk of electrical shock from lightning.
• Never connect or use a modem in a wet environment.
• Do not plug a modem or telephone cable into the network interface controller (NIC) receptacle.
• Disconnect the modem cable before opening a product enclosure, touching or installing internal components, or
touching an uninsulated modem cable or jack.
