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.

5.2 Unpacking and Installing Oracle Exadata Rack

Oracle Rack Cabinet 1242 is the rack cabinet used for all Oracle Exadata Rack models since Oracle Exadata X7.

Use the following resources for information on unpacking and installing Oracle Exadata Rack:

• For an outline of the recommended procedures, see the Oracle Rack Cabinet 1242 Getting Started Guide at https://docs.oracle.com/cd/E85660_01/html/E85665/index.html.

• For additional details, consult the Oracle Rack Cabinet 1242 User's Guide at https://docs.oracle.com/en/servers/options/rack-cabinet-1242/user-guide/index.html.

5.3 Acclimating Oracle Exadata

Oracle recommends an acclimation period of 24 hours for Oracle Exadata.

The recommended acclimation period applies to all hardware, including racks and cables. Acclimation to the surrounding environment prevents damage as a result of condensation.

5.4 Powering on the System the First Time

Before powering on the system for the first time, it is necessary to inspect the machine, and connect the power cords.

• Inspecting the Machine After it is in Place
  This procedure describes how to visually examine the Oracle Exadata Rack physical system after it is in place, but before power is supplied.
• Connecting Power Cords
  
• Powering on Oracle Exadata Rack
  This procedure describes how to power on Oracle Exadata Rack.

5.4.1 Inspecting the Machine After it is in Place

This procedure describes how to visually examine the Oracle Exadata Rack physical system after it is in place, but before power is supplied.

1. Check the rack for damage.

2. Check the rack for loose or missing screws.

3. Check Oracle Exadata Rack for the ordered configuration. Refer to the Customer Information Sheet (CIS) on the side of the packaging.

4. Check that all cable connections are secure and firmly in place as follows:

   1. Check the power cables. Ensure that the correct connectors have been supplied for the data center facility power source.

   2. Check the network data cables.

5. Check the site location tile arrangement for cable access and airflow.

6. Check the data center airflow that leads in to the front of Oracle Exadata Rack.

5.4.2 Connecting Power Cords

The following procedure describes how to connect power cords to Oracle Exadata Rack:

1. Open the rear cabinet door.

2. Ensure that the correct power connectors have been supplied.

3. Unfasten the power cord cable ties. The ties are for shipping only and are no longer needed.

4. Route the power cords to the facility receptacles as shown in Figure 5-1.

5. Secure the power cords in bundles as shown in Figure 5-1.

6. Plug the PDU power cord connectors into the facility receptacles. Ensure the breaker switches are in the OFF position before connecting the power cables.

5.4.3 Powering on Oracle Exadata Rack

This procedure describes how to power on Oracle Exadata Rack.

Note:

Oracle Exadata Database Machine X2-8 Full Rack database servers may take up to 15 minutes to start through the normal BIOS POST tests.

1. Switch on the PDU B circuit breakers, one at a time. PDU B is on the right side of the rack when viewed from the rear. The circuit breakers are on the rear of the Oracle Exadata Rack cabinet as shown in the following figure. Press the ON (|) side of the toggle switch. When the breaker is in the ON position, the breakers are flush with the side of the PDU.

2. Verify the expected power LEDs are on. The LEDs are located as follows:

   • Database servers: Right-hand LED

   • Storage Servers: Top LED

   • Cisco Management Network Switch: Left LED (viewed from front) is green, and the other LEDs are red

   • InfiniBand Network Fabric switches: Left LED (viewed from front) labeled PS0, or right LED (viewed from front) labeled PS1

   • Cisco RoCE Network Fabric switches: Left LED (viewed from front) labeled P1, or right LED (viewed from front) labeled P2

   • KVM switch on Oracle Exadata Database Machine X2-2: Lower LED B

   • KMM switch on Oracle Exadata Database Machine X2-2: Only supplied by PDU B

3. Connect power to PDU A. Ensure the breaker switches are in the OFF position before connecting the power cables.

4. Switch on the PDU A circuit breakers, one at a time.

5. Verify the expected LEDs are on.

6. Perform a visual check of all cable connections in the rack. Do not press every connector to verify connection.

7. Verify the OK LED is blinking standby for all systems. The OK LED blinks on for 0.1 seconds, once every 3 seconds when in standby mode. The OK LED does not blink when the ILOM is starting. The LED remains dark until it goes to standby mode after 2 to 3 minutes.
