Lenovo ThinkServer RD240 Rack Installation Instructions

Rack installation instructions

Be sure to read and understand the documentation that comes with the rack cabinet for safety and
cabling information. Before you install the server in a rack cabinet, review the following guidelines:
v Two or more people are required to install devices 2U or larger in a rack cabinet.
v Make sure that the room air temperature is below 35°C (95°F).
v Do not block any air vents; usually 15 cm (6 inches) of space provides proper airflow.
v Do not leave open spaces above or below an installed server in your rack cabinet. To help prevent
damage to server components, always install a blank filler panel to cover the open space and to help
ensure proper air circulation.
v Install the server only in a rack cabinet with perforated doors.
v Start from the bottom of the rack cabinet for the device installation.
v Install the heaviest device in the bottom of the rack cabinet.
v Do not extend more than one device out of the rack cabinet at the same time.
v Remove the rack doors and side panels to provide easier access during installation.
v Connect the server to a properly grounded outlet.
v Do not overload the electrical outlet when you install multiple devices in the rack cabinet.
v Install the server in a rack that meets the following requirements:
– Minimum depth of 70 mm (2.76 inches) between the front mounting flange and inside of the front
door.
– Minimum depth of 157 mm (6.18 inches) between the rear mounting flange and inside of the rear
door.
– Minimum depth of 740 mm (29.13 inches) and maximum depth of 910 mm (35.83 inches) between
the front and rear mounting flanges to support the use of the cable-management arm.

rack-mounted devices.
