to ensure they are connected to the proper ports.
f.
Connect the power cable to the lower PSU and route it through each basket.
g. Close all of the baskets.
h. If the Ultrastar Data102 is being installed in a rack and will subsequently be transported
inside that rack, it is important to use the included cable tie to wrap the CMA bundle to
ensure it does not get damaged during transport. If the Ultrastar Data102 is instead being
installed where it will operated, skip this step. Remember to remove the cable ties after the
enclosure has reached its final operational location.
i. Reconnect the arm to the rail by the connector at the elbow.
Step 36 : Cable the upper CMA.
a. Unlatch the elbow side of the CMA arm and swing it forward by pressing the blue button
that says "push" to unlatch it.
Important: Make sure the power cable is not connected to a PDU. If it is,
the system will power up when the cable is plugged into the PSU. This is not
intended at this stage of installation.
