When connecting or disconnecting power to hot-pluggable power supplies, if offered with your system, observe
the following guidelines:
– Install the power supply before connecting the power cable to the power supply.
– Unplug the power cable before removing the power supply.
– If the system has multiple sources of power, disconnect power from the system by unplugging all power cables
from the power supplies.
Move products with care; ensure that all casters and/or stabilizers are firmly connected to the system. Avoid
sudden stops and uneven surfaces.
General Precautions for Rack-Mountable Products
Observe the following precautions for rack stability and safety. Also refer to the rack installation documentation
accompanying the system and the rack for specific caution statements and procedures.
Systems are considered to be components in a rack. Thus, "component" refers to any system as well as to various
peripherals or supporting hardware.
CAUTION: Installing systems in a rack without the front and side stabilizers installed could cause
the rack to tip over, potentially resulting in bodily injury under certain circumstances. Therefore,
always install the stabilizers before installing components in the rack.
After installing system/components in a rack, never pull more than one component out of the
rack on its slide assemblies at one time. The weight of more than one extended component
could cause the rack to tip over and may result in serious injury.
Before working on the rack, make sure that the stabilizers are secured to the rack, extended to the floor, and that
the full weight of the rack rests on the floor. Install front and side stabilizers on a single rack or front stabilizers
for joined multiple racks before working on the rack.
Always load the rack from the bottom up, and load the heaviest item in the rack first.
Make sure that the rack is level and stable before extending a component from the rack.
Use caution when pressing the component rail release latches and sliding a component into or out of a rack; the
slide rails can pinch your fingers.
After a component is inserted into the rack, carefully extend the rail into a locking position, and then slide the
component into the rack.
Do not overload the AC supply branch circuit that provides power to the rack. The total rack load should not
exceed 80 percent of the branch circuit rating.
Ensure that proper airflow is provided to components in the rack.
Do not step on or stand on any component when servicing other components in a rack.
NOTE: A qualified electrician must perform all connections to DC power and to safety grounds.
All electrical wiring must comply with applicable local or national codes and practices.
CAUTION:
Never defeat the ground conductor or operate the equipment in the absence of a
suitably installed ground conductor. Contact the appropriate electrical inspection authority or an
electrician if you are uncertain that suitable grounding is available.
CAUTION:
The system chassis must be positively grounded to the rack cabinet frame. Do not
attempt to connect power to the system until grounding cables are connected. Completed power
and safety ground wiring must be inspected by a qualified electrical inspector. An energy hazard
will exist if the safety ground cable is omitted or disconnected.
