The standard port replicator also doubles as a desktop stand
for the HAMMERHEAD 3. Simply press the male docking
connector on the port replicator into the female docking
connector on the back of the unit. The connectors are correctly
oriented and only fit in one direction. It is impossible to join
them incorrectly. Make sure the connector is fully inserted
confirming the port replicator fits snuggly against the back of
the computer. Turn the thumbscrews in a clockwise direction
to insure a reliable, positive connection. Do not over tighten.
Do not connect the port replicator to the computer while power
is attached to the port replicator. Attach the port replicator and
then attach the power to the port replicator.
Flat port replicators and custom cable sets are available when
connectivity is needed while the unit is mobile. External power
should be connected to the port replicators after being firmly
connected to the HAMMERHEAD 3. Some custom
configurations provide access to ports in the computer
housing.
