Chapter 3. Installing The 1U Pdu Horizontally In A Rack Cabinet - Lenovo 46M4002 Installation And Maintenance Manual

Chapter 3. Installing the 1U PDU horizontally in a rack cabinet

Attention: Horizontal installation of a PDU is not supported during relocation or shipping of a rack cabinet.
You must remove any horizontally mounted PDUs from the EIA mounting space before you relocate the rack
cabinet.
Note: Removing the rack doors and side panels might make installation easier. See the rack cabinet
documentation for more information.
Review the documentation that comes with your rack cabinet for safety and cabling information. When you
install the PDU in a rack cabinet, observe the following precautions:
• Make sure that the room air temperature is below 35°C (95°F).
• Do not block any air vents; usually 15 cm (6 in.) of air space provides proper airflow.
• Plan the device installation starting from the bottom of the rack cabinet.
• Install the heaviest device in the bottom of the rack cabinet.
• Do not extend more than one device out of the rack cabinet at the same time.
• Connect all power cords to properly wired and grounded electrical outlets.
• Do not overload the power outlet when you install multiple devices in the rack cabinet.
Use cage nuts for rack cabinets with square holes, and use clip nuts for rack cabinets with round holes. If
your rack cabinet requires cage nuts, use a cage-nut-insertion tool or a flat-blade screwdriver to install them.
