WARNING:

troubleshooting and repair procedures that may be shown are for reference and minor repair only. Because of the
complexity of the individual components and subassemblies, no one should attempt to make repairs at the

And any indications of component replacement or printed wiring board modifications may void any warranty.
WARNING:
To reduce the risk of electrical shock or damage to the equipment:

•
Disconnect the power from the computer by unplugging the power cord either from the electrical outlet or
the computer.

To properly ventilate your system, you must provide at least 3 inches (7.6 cm) of clearance at the front
and back of the HDDR unit.
