6.3 Rack-mount Safety Precautions

This section describes rack-mount safety precautions you must follow when installing a compute node into your Oracle PCA.

Caution

Leveling feet position: When unpacking at the installation site, or when repackaging and moving the rack to a new location, verify that the leveling feet are up before moving the rack.

Caution

Stabilize rack: Deploy the anti-tilt bar on the equipment rack before starting an installation.

Caution

Shipping brackets: The rack shipping brackets are not for use for bracing or anchoring the rack during seismic events.

Caution

Equipment loading: Always load equipment into a rack from the bottom up so that the rack does not become top-heavy and tip over. Deploy your rack anti-tilt bar to prevent the rack from tipping during equipment installation.

Caution

Lifting equipment: Oracle Server X7-2 weighs approximately 35 lbs (15.88 kg). Two people are needed to mount the server into the rack enclosure.

Caution

Communicate instructions: When performing a two-person procedure, communicate your intentions clearly to the other person before, during, and after each step to minimize confusion.

Caution

Elevated operating ambient temperature: If you install the server in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment might be higher than the room ambient temperature. Install the equipment in an environment compatible with the maximum ambient temperature (Tma) specified for the server. For information, refer to Section 2.5, “Ventilation and Cooling Requirements”.

Caution

Reduced airflow: Install the equipment in a rack so that it does not compromise the amount of airflow required for safe operation of the equipment.

Caution

Mechanical loading: Mount the equipment in the rack so that it does not cause a hazardous condition due to uneven mechanical loading.

Caution

Circuit overloading: Consider the connection of the equipment to the supply circuit and the effect that overloading the circuits might have on over-current protection and supply wiring. Also consider the equipment nameplate power ratings used when you address this concern.

Caution

Reliable earthing: Maintain reliable earthing of rackmounted equipment. Pay attention to supply connections other than direct connections to the branch circuit (for example, use of power strips).

Caution

Mounted equipment: Do not use slide-rail-mounted equipment as a shelf or a workspace.
