Power Supplies

The Z9000 is designed to support two hot-swappable PSUs.
NOTE: If you use a single PSU, you must install a blank plate in the other PSU
slot. Dell Force10 recommends using power supply 1 (PSU1) as the blank plate
slot.
WARNING: To prevent electrical shock, ensure 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: ESD damage can occur if the components are mishandled.
Always wear an ESD-preventive wrist or heel ground strap when handling the
Z9000 and its components.
