Chapter 1. Safety information

The topic provides safety guidelines that you need to read before you install the server in a rack cabinet.
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:
Notes:
• Use the M6 screws that come with slide rails to install the server in a rack cabinet if you plan to transport
the rack cabinet to another location with the server installed or the rack is in a vibration-prone area.
• You can install the cable management arm on either side of the rack. These instructions are shown with
the cable management arm mounted on the left side. The installation instructions in this document can be
reversed if you are installing the cable management arm on the other side of the rack.
• Two or more people are required to install devices 2U or larger in a rack cabinet.
• See the server documentation for the maximum room air temperature.
• Do not block any air vents; usually 15 cm (6 in.) of space provides proper airflow.
• 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.
• Install the server only in a rack cabinet with perforated doors.
• 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.
• Remove the rack doors and side panels to provide easier access during installation.
• Connect the server to a properly grounded outlet.
• Do not overload the power outlet when you install multiple devices in the rack cabinet.
• 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.
– Minimum depth of 718 mm (28.27 in.) and maximum depth of 762 mm (30 in.) between the front and
rear mounting flanges to support the use of the cable management arm.
Note: The maximum distance between the front and the rear EIA rails of the rack is 810 mm (31.9 in.).
