3.3 Before You Begin

Before installing Oracle Exalytics In-Memory Machine into a rack, read the following cautions and important notes:

• Always load equipment into a rack from the bottom up, so that the rack will not become top-heavy and tip over. Deploy your rack's anti-tip bar to prevent the rack from tipping during equipment installation.

• If the Oracle Exalytics In-Memory Machine is installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment might be greater than room ambient temperature. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified for the Oracle Exalytics In-Memory Machine.

• Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.

• Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.

• Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on over-current protection and supply wiring. Appropriate consideration of equipment nameplate power ratings should be used when addressing this concern.

• Reliable earthing of rackmounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (for example, use of power strips).

• Slide-rail mounted equipment must not be used as a shelf or a work space.

3.4 Disassembling the Slide-Rails

To disassemble the slide-rails before the installation, complete the following steps:

1. Unpack the slide-rails.

2. Locate the slide-rail lock at the front of the slide-rail assembly, as shown in Figure 3-1.

3. Press and hold the slide-rail lock toward the direction of the arrow, while you pull the mounting bracket out of the slide-rail assembly until it reaches the stop, as shown in Figure 3-1.

4. Push the mounting bracket release button toward the front of the mounting bracket (Figure 3-1), and simultaneously withdraw the mounting bracket from the slide-rail assembly.

   Description of "Figure 3-2 Installing the Mounting Brackets"
   
   

2. With the heads of the five chassis locating pins protruding though the five keyhole openings in the mounting bracket, pull the mounting bracket toward the front of the chassis until the mounting bracket clip locks into place with an audible click, as shown in Figure 3-2.

3. Verify that the rear locating pin has engaged the mounting bracket clip.

4. Repeat to install the remaining mounting bracket on the other side of the Oracle Exalytics In-Memory Machine.

3.6 Attaching the Slide-Rail Assemblies to the Rack

The slide rail assemblies support only racks with 9.5-mm square holes and M6 round holes. All other racks, including those racks with 7.2-mm, M5, or 10-32 mounting holes, are not supported. See your rack documentation for information about the size of its rail holes.

To attach the slide-rail assemblies to the rack, complete the following steps:

1. (Optional) If you need to move the rack with the Oracle Exalytics In-Memory Machine installed, it is recommended that you attach the slide-rail assembly with mounting screws and cage nuts.

   Note:

   Insert the cage nuts prior to performing the next step. See the Rail Rackmount Kit Overview and Information card for instructions on inserting these cage nuts. This card is included with the rack kit.

2. Position a slide-rail assembly in your rack, so that the slide-rail assembly front bracket is on the outside of the front rack post and the slide-rail assembly rear bracket is on the inside of the rear rack post, as shown in Figure 3-3.

3. Align the slide-rail assembly mounting pins with the front and rear rack post mounting holes. Then lock the assembly into place by pushing the assembly toward the rear of the rack until the mounting pins engage the rack, as shown in Figure 3-4.

   You will hear an audible click when the mounting pins engage the rack.

   Note:

   The slide assembly mounting pins accommodate either 9.5 mm square mounting holes or M6 round mounting holes. No other mounting hole sizes are supported.

   Caution:

   If your rack does not have an anti-tip bar, the rack could tip over.

3.7 Installing Oracle Exalytics In-Memory Machine into the Slide-Rail Assemblies

Use this procedure to install the Oracle Exalytics In-Memory Machine chassis, with mounting brackets, into the slide-rail assemblies that are mounted to the rack.

Caution:

This procedure requires a minimum of two persons because of the weight of the Oracle Exalytics In-Memory Machine. Attempting this procedure alone could result in equipment damage or personal injury.

Always load equipment into a rack from the bottom up so that the rack will not become top-heavy and tip over. Extend your rack's anti-tip bar to prevent the rack from tipping during equipment installation.

To install Oracle Exalytics In-Memory Machine into the slide-rail assemblies, complete the following steps:

1. Push the slide-rails into the slide-rail assemblies in the rack as far as possible.

2. Raise the Oracle Exalytics In-Memory Machine so that the rear ends of the mounting brackets are aligned with the slide-rail assemblies that are mounted in the rack, as shown in Figure 3-7.

3. Insert the mounting brackets into the slide-rails, then push the server into the rack until the mounting brackets encounter the slide-rail stops (approximately 12 inches, or 30 cm).

   Caution:

   When inserting the Oracle Exalytics In-Memory Machine into the slide-rail, ensure that both the top and bottom mounting lips of the mounting brackets are inserted into the slide-rail. The Oracle Exalytics In-Memory Machine should slide forward and backward easily if correctly installed. If the unit does not slide easily, ensure that each mounting lip is inserted properly. If the mounting brackets are not inserted properly, the unit may fall when removing it from the rack.

3.9 Verifying the Operation of the Slide Rails and CMA

Use the following procedure to ensure that the slide-rails and CMA are operating correctly.

Note:

Two persons are recommended for this procedure: one to move the Oracle Exalytics In-Memory Machine in and out of the rack, and one to observe the cables and CMA.

1. Slowly pull the Oracle Exalytics In-Memory Machine out of the rack until the slide-rails reach their stops.

2. Inspect the attached cables for any binding or kinks.

3. Verify that the CMA extends fully from the slide-rails.

4. Push the Oracle Exalytics In-Memory Machine back into the rack, as described in the following sub-steps.

   When the Oracle Exalytics In-Memory Machine is fully extended, you must release two sets of slide-rail stops to return the Oracle Exalytics In-Memory Machine to the rack:

   • The first set of stops are levers, located on the inside of each slide-rail, just behind the back panel of the Oracle Exalytics In-Memory Machine. Push in both green levers simultaneously and slide the Oracle Exalytics In-Memory Machine toward the rack. The Oracle Exalytics In-Memory Machine will slide in approximately 18 inches (46 cm) and stop. Verify that the cables and the CMA retract without binding before you continue.

   • The second set of stops are the slide-rail release buttons, located near the front of each mounting bracket (Figure 3-1). Simultaneously push both of the green slide-rail release buttons, and push the Oracle Exalytics In-Memory Machine completely into the rack until both slide-rail locks engage.

5. Adjust the cable straps and CMA, as required.
