Use the following safety guidelines to help ensure your own personal safety and to help protect your system and working environment from potential damage.
CAUTION: There is a danger of a new battery exploding if it is incorrectly installed. Replace the battery only with the same or equivalent type recommended by the manufacturer. See SAFETY: Battery Disposal.
NOTE: See the safety regulations and warnings stated in the documentation that ships with your PowerEdge™ system/Dell Precision™ workstation.
SAFETY: General
Observe and follow service markings. Do not service any product except as explained in your user documentation. Opening or removing covers that are marked with the triangular symbol with a lightning bolt may expose you to electrical shock. Components inside these compartments should be serviced only by a trained service technician.
If any of the following conditions occur, unplug the product from the electrical outlet and replace the part or contact your trained service provider:
The power cable, extension cable, or plug is damaged.
An object has fallen into the product.
The product has been exposed to water.
The product has been dropped or damaged.
The product does not operate correctly when you follow the operating instructions.
Use the product only with approved equipment.
Operate the product only from the type of external power source indicated on the electrical ratings label. If you are not sure of the type of power source required, consult your service provider or local power company.
Handle batteries carefully. Do not disassemble, crush, puncture, short external contacts, dispose of in fire or water, or expose batteries to temperatures higher than 60 degrees Celsius (140 degrees Fahrenheit). Do not attempt to open or service batteries; replace batteries only with batteries designated for the product.
SAFETY: When Working Inside Your System
Before you remove the system covers, perform the following steps in the sequence indicated.
CAUTION: Except as expressly otherwise instructed in Dell documentation, only trained service technicians are authorized to remove the system cover and access any of the components inside the system.
NOTICE: To help avoid possible damage to the system board, wait 5 seconds after turning off the system before removing a component from the system board or disconnecting a peripheral device.
Turn off the system and any devices.
Ground yourself by touchingan unpainted metal surface on the chassis before touching anything inside the system.
While you work, periodically touch an unpainted metal surface on the chassis to dissipate any static electricity that might harm
internal components.
Disconnectyour system and devices from their power sources. To reduce the potential of personal injury or shock, disconnect
any telecommunication lines from the system.
In addition, take note of these safety guidelines when appropriate:
When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some cables have a connector with locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before disconnecting the cable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before you connect a cable, make sure that both connectors are correctly oriented and aligned.
Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its edges or by its metal mounting bracket. Hold a component such as a microprocessor chip by its edges, not by its pins.
Protecting Against Electrostatic Discharge
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 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 an I/O connector 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 the instructions included in the section RAID Configuration and Management.
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.
