Feature Description
Thunderbolt Ports Use a Thunderbolt cable to connect the Pegasus2 to a Thunderbolt ready computer.
This connection completes the physical link, it is the path through which the SATA
link is established.
Cooling Vents The cooling vents on the back should be clear and unobstructed to allow proper
airowfordiskandsystemcooling.Notethattheairintakeventslocatedonthefront
of the enclosure should also be unobstructed.
Power Receptacle Use only the power cord shipped with the device to connect the power. Insert one
end of the power cord into the power receptacle and insert the other end into a
suitable power source such as a wall outlet or a power strip.
Note
As far as the location of the Thunderbolt ports is concerned, the back of the R4, R6
and R8 are identical, i.e. near the top and left of center. The power connection is in
the lower right corner on both devices.
