Safety Precautions When Rackmounting the Storage Server
■
Ensure that your site meets the required electrical and environmental requirements. See
“System Specifications” on page 15 .
Safety Precautions When Rackmounting the Storage Server
This section describes safety precautions you must follow when installing the storage server
into a rack.
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 or legs on the equipment rack before
beginning an installation.
Caution -
Elevated operating ambient temperature : If the storage server 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 storage server. For storage server environmental requirements, see
“Environmental Specifications” on page 16 .
Caution -
Reduced airflow
: Installation of the equipment in a rack should be such that the
amount of airflow required for safe operation of the equipment is not compromised.
Caution -
Mechanical loading : Mounting of the equipment in the rack should be such that a
hazardous condition is not created due to uneven mechanical loading.
Caution -
Circuit overloading:
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.
Caution -
Reliable earthing: 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).
