This chapter describes how to move, install and configure the hardware through to powering on the system.

Note:

For ease of reading, the name "Oracle Exadata Rack" is used when information refers to both Oracle Exadata Database Machine and Oracle Exadata Storage Expansion Rack.

5.1 Reviewing Safety Guidelines

Before Oracle Exadata Rack arrives, the following safety precautions should be reviewed to ensure the site is safe, as well as ready for delivery.

Failing to observe these precautions can result in injury, equipment damage, or malfunction.

  • Do not block ventilation openings.

  • Do not install Oracle Exadata Rack in a location that is exposed to direct sunlight or near a device that may become hot.

  • Do not install Oracle Exadata Rack in a location that is exposed to excessive dust, corrosive gases, or air with high salt concentrations.

  • Do not install Oracle Exadata Rack in a location that is exposed to frequent vibrations. Install Oracle Exadata Rack on a flat, level surface.

  • Use a power outlet that uses proper grounding. When using shared grounding, the grounding resistance must not be greater than 10 ohms. Ensure that your facility administrator or a qualified electrical engineer verifies the grounding method for the building, and performs the grounding work.

  • Be sure that each grounding wire used for Oracle Exadata Rack is used exclusively for Oracle Exadata Rack. Also be sure to observe the precautions, warnings, and notes about handling that appear on labels on the equipment.

  • Do not place cables under the equipment or stretch the cables too tightly.

  • Do not disconnect power cords from the equipment while its power is on.

  • If you cannot reach the connector lock when disconnecting LAN cables, then press the connector lock with a flathead screwdriver to disconnect the cable. You could damage the system board if you force your fingers into the gap rather than using a flathead screwdriver.

  • Do not place anything on top of Oracle Exadata Rack or perform any work directly above the rack.

  • Do not let the room temperature rise sharply, especially in winter. Sudden temperature changes can cause condensation to form inside Oracle Exadata Rack. Allow for a sufficient warm-up period prior to server operation.

  • Do not install Oracle Exadata Rack near a photocopy machine, air conditioner, welding machine, or any other equipment that generates loud, electronic noises.

  • Avoid static electricity at the installation location. Static electricity transferred to Oracle Exadata Rack can cause malfunctions. Static electricity is often generated on carpets.

  • Confirm the supply voltage and frequency match the electrical ratings indicated for Oracle Exadata Rack.

  • Do not insert anything into any Oracle Exadata Rack opening, unless doing so is part of a documented procedure. Oracle Exadata Rack contains high-voltage parts. If a metal object or other electrically-conductive object enters an opening in Oracle Exadata Rack, then it could cause a short circuit. This could result in personal injury, fire, electric shock, and equipment damage.

  • When using single phase power distribution units (PDUs), note the following:

    • PDU A input 0 and PDU B input 2 must be on the same phase.

    • PDU A input 1 and PDU B input 1 must be on the same phase.

    • PDU A input 2 and PDU B input 0 must be on the same phase.

    The inputs are labeled where they come out of the PDU. Connecting cables as described ensures the phases are balanced on both sides, A and B, in case of a failover.

5.3.3 Attaching a Ground Cable (Optional)

The Oracle Exadata Rack power distribution units (PDUs) achieve earth ground through their power cords. Final chassis ground is achieved by way of the ground prong when you connect the power cord to a socket. For additional grounding, attach a chassis earth ground cable to Oracle Exadata Rack. The additional ground point enables electrical current leakage to dissipate more efficiently.

WARNING:

The PDU power input lead cords and the ground cable must reference a common earth ground. If they do not, then a difference in ground potential can be introduced. If you are unsure of your facility's PDU receptacle grounding, then do not install a ground cable until you confirm that there is a proper PDU receptacle grounding. If a difference in ground potential is apparent, then you must take corrective action.

Note:

A grounding cable is not shipped with the system.

  1. Ensure the installation site has properly grounded the power source in the data center. The facility PDU must have earth ground.

  2. Ensure all grounding points, such as raised floors and power receptacles, reference the facility ground.

  3. Ensure that direct, metal-to-metal contact is made for this installation. During manufacturing, the ground cable attachment area might have been painted or coated.

  4. Attach the ground cable to one of the attachment points located at the bottom rear of the system frame as shown in Figure 5-7. The attachment point is an adjustable bolt that is inside the rear of the Oracle Exadata Rack cabinet on the right side.
