WARNING: This system may have more than one power supply
cable. To reduce the risk of electrical shock, a trained service
technician must disconnect all power supply cables before servicing
the system.
WARNING: The power supplies in your computer system may
produce high voltages and energy hazards, which can cause bodily
harm. Only trained service technicians are authorized to remove
the computer covers and access any of the components inside the
computer.
WARNING FOR YOUR PERSONAL SAFETY AND PROTECTION OF THE EQUIPMENT
Before starting to work on the computer, perform the following steps in the sequence listed:
1. Turn off your computer and any devices.
2. Ground yourself by touching an unpainted metal surface on the chassis, such as the metal around the card-slot openings at the
back of the computer, before touching anything inside your computer.
While you work, periodically touch an unpainted metal surface on the computer chassis to dissipate any static electricity that
might harm internal components.
3. Disconnect your computer and devices from their power sources. Also, disconnect any telephone or telecommunication lines from
the computer.
Precautions for Rack-Mountable Products
Observe the following precautions for rack stability and safety. Also refer to the rack installation documentation accompanying the system and
the rack for specific warning and/or caution statements and procedures.
WARNING: Installing Dell system components in a Dell rack without the front and side stabilizers installed could cause the
rack to tip 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 injure someone.
NOTE: Dell’s server and storage systems are certified as components for use in Dell’s rack cabinet using the Dell customer rack kit.
The final installation of Dell systems and rack kits in any other brand of rack cabinet has not been approved by any safety agencies. It
is the customer’s responsibility to have the final combination of Dell systems and rack kits for use in other brands of rack cabinets
evaluated for suitability by a certified safety agency.
System rack kits are intended to be installed in a Dell rack by trained service technicians. If you install the kit in any other rack, be sure
that the rack meets the specifications of the American National Standards Institute (ANSI)/Electronic Industries Association (EIA)
standard ANSI/EIA-310-D-92, International Electrotechnical Commission (IEC) 297, and Deutsche Industrie Norm (DIN) 41494. One
rack kit is required for each PowerEdge™ computer system that is installed in a rack.
Do not move large racks by yourself. Due to the height and weight of the rack, Dell recommends a minimum of two people to accomplish
this task.
Before working on the rack, make sure that the stabilizer feet are secure to the rack, extend to the floor, and that the full weight of the
rack rests on the floor. Install front and side stabilizer feet on a single rack or front stabilizer feet 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.
Extend only one component at a time 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.
