Note:
v Removing the rack doors and side panels might make installation easier. See the
rack documentation for more information.
v The PDU must be installed with the input power cord toward the bottom end of
the PDU.
Review the documentation that comes with your rack for safety and cabling
information. When you install the PDU in a rack, observe the following
precautions:
v Make sure that the room air temperature is below 40°C (104°F).
v Do not block any air vents; usually 15 cm (6 in.) of air space provides proper
airflow.
v Connect all power cords to properly wired and grounded electrical outlets.
v Do not overload the power outlet when you install multiple devices in the rack.
You must use clip nuts to install the mounting brackets. Clip nuts come with the
PDU and are installed on the rack mounting flanges, as shown in the following
illustration.
To install the PDU in the 1U mounting space in the side of an IBM Enterprise rack,
