SAFETY: Rack Mounting of System Components Observe the following precautions for rack stability and safety. Also refer to the rack installation documentation accompanying the equipment and the rack for specific caution statements and procedures. NOTE: Your equipment is safety certified as a free-standing unit or as rackmounted component for use in a Dell rack cabinet using the customer rack kit. Systems are considered to be components in a rack; thus, “component” refers to any system as well as to various peripherals or supporting hardware. The installation of your equipment 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 equipment 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. Installing System Components in Your Rack 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. • 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. Working on Your Rack or Your Rack-Mounted Components CAUTION: Do not move racks by yourself. Due to the height and weight of the rack, a minimum of two people should perform this task. • Before working on the rack, ensure 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. • After installing equipment/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. SAFETY: Equipment Using -48V DC Power Supplies Systems using -48V DC Power Supplies are intended for restricted access locations (dedicated equipment rooms, equipment closet, or the like) in accordance with Articles 110-5, 110-6, 110-11, 110-14, and 110-17 of the National Electrical Code, American National Standards Institute (ANSI)/National Fire Protection Association (NFPA) 70. • Connect the equipment to a 48-V direct current (DC) supply source that is electrically isolated from the AC source. The 48VDC source is to be reliably connected to earth. CAUTION: A qualified electrician must perform all connections to DC power and to safety grounds. All electrical wiring must comply with applicable local or national codes and practices. CAUTION: Before connecting safety ground or power cables to the connector, ensure that the power is removed from the DC circuit. To ensure that the power is off, locate the circuit breaker on the DC source circuit (usually at the power distribution of the battery distribution fuse bay). Switch the circuit breaker to the off position and, if available, install an approved safety locking device on the circuit breaker or switch. CAUTION: While grounding techniques may vary, a positive connection to a safety (earth) ground is a requirement. CAUTION: When installing the unit, the ground connection must always be made first and disconnected last to prevent an energy hazard. CAUTION: Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. CAUTION: The system chassis must be securely grounded to the rack cabinet frame. Do not attempt to connect power to the system until grounding cables are connected. Completed power and safety ground wiring must be inspected by a qualified electrical inspector. An energy hazard will exist if the safety ground cable is omitted or disconnected. • Wire the unit with copper wire only, and unless otherwise specified, use 14 American Wire Gauge (AWG) wire, and protect it with a 7.2-ampere (A) minimum to a 20-A maximum protective device or a 25-A maximum protective device when used with 90ºC wire. CAUTION: When stranded wiring is required, use approved wiring termination, such as closed-loop or spade- type with upturned lugs. These terminations should be the appropriate size for the wires and must be double crimped, one on the conductor and one on the insulation. Protecting Against Electrostatic Discharge CAUTION: Disconnect product from mains power source in accordance with product-specific safety information located on the “Safety Information” section of this website. Electrostatic discharge (ESD) events can harm electronic components inside your computer. Under certain conditions, ESD may build up on your body or an object, such as a peripheral, and then discharge into another object, such as your computer. To prevent ESD damage, you should discharge static electricity from your body before you interact with any of your computer’s internal electronic components, such as a memory module. You can protect against ESD and discharge static electricity from your body by touching a metal grounded object (such as an unpainted metal surface on your computer’s I/O panel) before you interact with anything electronic. When connecting a peripheral (including handheld digital assistants) to your computer, you should always ground both yourself and the peripheral before connecting it to the computer. In addition, as you work inside the computer, periodically touch a metal-grounded object to remove any static charge your body may have accumulated. You can also take the following steps to prevent damage from electrostatic discharge: • • • When unpacking a static-sensitive component from its shipping carton, do not remove the component from the antistatic packing material until you are ready to install the component. Just before unwrapping the antistatic package, be sure to discharge static electricity from your body. When transporting a sensitive component, first place it in an antistatic container or packaging. Handle all electrostatic sensitive components in a static-safe area. If possible, use antistatic floor pads and work bench pads. SAFETY: Battery Disposal Your system may use a nickel-metal hydride (NiMH), lithium coin-cell, and/or a lithium-ion battery. The NiMH, lithium coin-cell, and lithium-ion batteries are long-life batteries, and it is very possible that you will never need to replace them. However, should you need to replace them, refer to your system documentation for instructions. Do not dispose of the battery along with household waste. Contact your local waste disposal agency for the address of the nearest battery deposit site. NOTE: Your system may also include circuit cards or other components that contain batteries. These batteries must also be disposed of in a battery deposit site. For information about such batteries, refer to the documentation for the specific card or component.
