3. Dual Port Configurations
The RAX421D-XJ and RAX425D-XJ support two host machines connected
via two multi-lane SAS/SATA (SFF-8088) connections. Both hosts on a
dual port configuration cannot simultaneously write to the RAX unit. A
dual port configuration only ensures redundancy in case one host machine
is disabled or goes down.
4. Rack Mounting Warnings
Elevated Operating Ambient Temperature: The operating ambient temperature of the
rack environment may be greater than the room ambient temperature if the enclosure is
installed in a closed or multi-unit rack assembly. Install the equipment in an environment
compatible with the maximum ambient temperature of 40° C.
Reduced Air Flow: Do not block or inhibit the air flow required for safe operation of the
enclosure.
Mechanical Loading: Use care when mounting the rack in order to prevent injury.
Circuit Overloading: Do not overload the circuits. Refer to the name plate ratings on the
equipment.

2. Operating Your RAX
Connect the SFF-8088 data cable to the RAX and your host computer. Plug in the power cord.
With hard drives in the unit, turn on the power.
For the RAX420-XJ, the drives will begin to spin up automatically.
For the RAX421-XJ, use the included set of keys to turn the key lock 90 degrees clockwise to
power on each hard drive.
For the RAX425-XJ, push in the power buttons on each frame until the LED lights up to power
on each hard drive.
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 being used. See the “Usage with
Mac and Windows Operating Systems” section of the complete User Manual for formatting
instructions.
