CRU RAX841-XJ 41405-1130-0000 Prospecto

Your RAX is now ready to use! If the hard drives are already formatted, the RAX can be used 
right away. If the hard drives are brand new, or the formats are not compatible with your 
computer, the drives will need to be formatted before usage. 

Elevated Operating Ambient Temperature: If installed in a closed or multi-unit rack 
assembly, the operating ambient temperature of the rack environment may be greater than 
room ambient. 

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 the circuits might have on over current 
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 (e.g. use of power strips).
