3.6.1.3 Circuit Overloading
Consideration should be given to the connection of the equipment to the power supply
circuitry and the effect that any possible overloading of circuits might have on
overcurrent protection and power supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
3.6.1.4 Reliable Ground
A reliable ground must always be maintained. To ensure this, the rack itself should be
grounded. Particular attention should be given to power supply connections other
than the direct connections to the branch circuit (for example, the use of power
strips, etc.).
To prevent bodily injury when mounting or servicing this unit in a rack, you must take
special precautions to ensure that the system remains stable. The following
guidelines are provided to ensure your safety:
• This unit should be mounted at the bottom of the rack if it is the only unit in
the rack.
• When mounting this unit in a partially filled rack, load the rack from the
bottom to the top with the heaviest component at the bottom of the rack.
• If the rack is provided with stabilizing devices, install the stabilizers before
mounting or servicing the unit in the rack.
Slide rail mounted equipment is not to be used as a shelf or a workspace.
Warning: do not pick up the server with the front handles. They are designed to pull
the system from a rack only.
