Back
e back of the J4 is where the power and underbolt connections are made. It includes the power button, a cooling exhaust vent.
Feature Description
Power Button
Press lightly to power on the J4. To shut down the device, press and hold the power button for 5 seconds to initiate a controlled system shut down power o.
Power Receptacle
Use only the power cord shipped with the device to connect the J4 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.
Cooling Exhaust Vent
The cooling vent on the back should be clear and unobstructed to allow proper airow for disk and system cooling. Note that the air intake vents should also be
unobstructed. These are located on the bottom of the device at the front and on both sides.
Thunderbolt Ports
Use a Thunderbolt cable to connect the J4 to a Thunderbolt ready computer. This connection completes the physical link to the J4, it is the path through which
the SATA link is established. Make sue the connector is oriented so that the Thunderbolt logo is facing down, i.e. on the underside of the connector, then
insert the connector into the port, pushing it strait in. Make sure the connector is pushed in so that the connector housing touches the back panel of the J4.
The J4 has two ports in order to allow the other port to be connected to a Thunderbolt display device, or to be daisy-chained another Pegasus attached storage
device. See “Daisy-Chaining Multiple Units” on page 25 for illustrations and instructions to daisy-chain two or more J4 units. The connection to other devices
does not require that the J4 be powered on, it functions at full speed for the other attached devices even if the J4 is not running.
