Chapter 3. Installing the 1U PDU horizontally in a rack
Attention: Horizontal installation of a PDU is not supported during relocation or
shipping of a rack. You must remove any horizontally mounted PDUs from the
EIA mounting space before you relocate the rack.
Note:
v
Removing the rack doors and side panels might make installation easier. See the
rack documentation for more information.
v
The PDU can be installed horizontally with the input power cord toward the
right or left side 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 Plan the device installation starting from the bottom of the rack.
v
Install the heaviest device in the bottom of the rack.
v
Do not extend more than one device out of the rack at the same time.
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.
Use cage nuts for racks with square holes, and use clip nuts for racks with round
holes. If your rack requires cage nuts, use a cage-nut-insertion tool or a flat-blade
screwdriver to install them.
