Rack installation instructions

Review 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 One or more people are required to install devices 1U or larger in a rack cabinet.

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 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 Plan the device installation starting from the bottom of the rack cabinet.

v Install the heaviest device in the bottom of the rack cabinet.

v Always install the tip plates on the rack.

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 power 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 in.) between the front mounting flange and inside of the front door.

– Minimum depth of 157 mm (6.18 in.) between the rear mounting flange and inside of the rear door.

Use safe practices when lifting.

≥18 kg (39.7 lb)
