Safety Instructions (continued)
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.
