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.

3. Tips for Rack Mounting RAX-XJ

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).

• For the RAX840-XJ and 845-XJ, the drives will begin to spin up
automatically.

• For the RAX841-XJ, use the included set of keys to turn the key lock 90
degrees clockwise to power on each hard drive.

• For the RAX845-XJ, push in the power buttons on each frame until the LED lights up to power
on each hard drive.
