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 60degrees 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.
1 Turn off the system and any devices.
2 Ground yourself by touching an unpainted metal surface on the chassis before touching anything inside the system.
3 While you work, periodically touch an unpainted metal surface on the chassis to dissipate any static electricity that might harm
internal components.
4 Disconnect your system and devices from their power sources. To reduce the potential of personal injury or shock, disconnect
any telecommunication lines from the system.
