Appendix C
Installation Prerequisites
Caution:
Observe these safety precautions:
Leveling feet position: When unpacking the rack 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.
Shipping brackets: The rack shipping brackets are not for use for bracing or
anchoring the rack during seismic events.
Stabilize rack: Deploy the anti-tilt bar on the equipment rack before starting an
installation.
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.
Lifting equipment: Oracle Server E5-2L weighs up to 76 lbs (34 kg). Two people
are needed to mount the server into the rack enclosure.
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.
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 server environmental requirements, see
Environmental Requirements.
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.
Mechanical loading: Mount the equipment in the rack so that it does not cause a
hazardous condition due to uneven mechanical loading.
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.
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).
Mounted equipment: Do not use slide-rail-mounted equipment as a shelf or a
workspace.
