Rack System Instructions
The following or similar rack-mount instructions are
included with the installation instructions:
・
Elevated Operating Ambient –
If installed in a
closed or multi-unit rack assembly, the operating
ambient temperature of the rack environment may be
greater than room ambient. Therefore, consideration
should be given to installing the equipment in an
environment compatible with the maximum ambient
temperature (Tma) specified by the manufacturer.
・
Reduced Air Flow –
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.
・
Mechanical Loading –
Mounting of the equipment in
the rack should be such that a hazardous condition is
not achieved due to uneven mechanical loading.
・
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 overcurrent protection and
supply wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing
this concern.
・
Reliable Earthing –
Reliable earthing of rack-
mounted 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).
Caution –
Slide/rail mounted equipment
must not be used as a shelf or workspace.
Rack System Warning
The following warnings apply to Racks and Rack
Mounted systems.
Caution –
For safety, equipment should
always be loaded from the bottom up. That
is, install the equipment that will be mounted
in the lowest part of the rack first, then the
next higher systems, etc.
Caution –
To prevent the rack from tipping
during equipment installation, the anti-tilt bar
on the rack must be deployed.
Caution –
To prevent extreme operating
temperature within the rack insure that the
maximum temperature does not exceed the
product’s ambient rated temperatures.
Caution –
To prevent extreme operating
temperatures due to reduced airflow
consideration should be made to the amount
of air flow that is required for a safe
operation of the equipment.
Caution –
Take adequate precautions when
moving a rack or library that contains rack-
installed equipment. The weight of some
rack equipment may have altered the rack or
library center of gravity and could cause an
overbalance/tip condition during a move.
