Power Supplies
The Z9000 is designed to support two hot-swappable power supplies.
NOTE: If using a single PSU, you must install a blank plate in the other PSU slot.
Dell Force10 recommends using PSU0, if installing only one power supply.
WARNING: To prevent electrical shock, make sure the Z9000 is grounded
properly. If you do not ground your equipment correctly, excessive emissions
may result. Use a qualified electrician to ensure that the power cables meet
your local electrical requirements.
WARNING: Electrostatic discharge (ESD) damage can occur if components
are mishandled. Always wear an ESD-preventive wrist or heel ground strap
when handling the Z9000 and its components.
