Operating the Equipment

Operating the Equipment

When operating the equipment, ensure safety precautions have been taken to prevent personal injury and equipment damage.

Power-on and Power-off

  • Before checking the device and cables, ensure that the system power supply is switched off; otherwise, loose cable connections may result in personal injury or equipment damage.
  • Do not wear an ESD strap when powering on the equipment to prevent a power shock.
  • Do not remove or insert cables and field replaceable units (FRUs) during system startup.
  • 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 electrical shock may occur if there is current in the cables.
Do not touch the device with bare hands in electrostatic sensitive areas. Wear an ESD wrist strap, ESD gloves, or ESD clothes to prevent personal injury or equipment damage.
When you perform troubleshooting, be aware of the following precautions:
  • Do not perform troubleshooting when during a thunderstorm.
