Safety precautions

This section details the primary steps to be followed before disassembling any device or component.

Observe the following safety precautions before any installation or break-fix procedures involving disassembly or reassembly:
  • Turn off the computer and all attached peripherals.
  • Disconnect the computer from AC power.
  • Disconnect all network cables and peripherals from the computer.
  • Use an ESD field service kit when working inside your computer to avoid electrostatic discharge (ESD) damage.
  • Place the removed component on an anti-static mat after removing it from the computer.
  • Press and hold the power button for 15 seconds to discharge the residual power in the system board.

Bonding

Bonding is a method for connecting two or more grounding conductors to the same electrical potential. This is done by using a field service electrostatic discharge (ESD) kit. When connecting a bonding wire, ensure that it is connected to bare metal and never to a painted or nonmetal surface. Ensure that the wrist strap is secure and in full contact with your skin. Remove all jewelry, watches, bracelets, or rings before grounding yourself and the equipment.
