Safety Precautions for Operating Equipment

When installing and maintaining devices, follow the electrical safety precautions to prevent personal injury and equipment damage.

Before checking device installation and cable connections, ensure that the system power supply is switched off. Otherwise, incorrect or loose cable connections may result in personal injury or equipment damage.
Do not wear an ESD wrist strap when powering on the equipment to prevent an electric shock.
- Do not remove or insert cables and field replaceable units (FRUs) during a system startup. Otherwise, data loss may occur.
- After you switch off the power supply, wait at least one minute before switching it back on.
- To avoid disk damage and data loss, do not switch the power supply off while any disk running indicators are still blinking.

Do not touch the connectors of power cables or communication cables. Otherwise, an electric shock may occur.
Do not touch devices with bare hands in electrostatic sensitive areas. Wear an ESD wrist strap, ESD gloves, or ESD clothing to prevent personal injury and equipment damage.

When performing troubleshooting, follow these precautions:

Do not perform troubleshooting during a thunderstorm.
Ensure that power cables are intact and the grounding measures are safe and effective.
Keep the troubleshooting area clean and dry.
