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:
vTwo or more people are required to install devices 2U or larger in a rack cabinet.
vMake sure that the room air temperature is below 35°C (95°F).
vDo not block any air vents; usually 15 cm (6 inches) of space provides proper airflow.
vDo 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.
vInstall the server only in a rack cabinet with perforated doors.
vStart from the bottom of the rack cabinet for the device installation.
vInstall the heaviest device in the bottom of the rack cabinet.
vDo not extend more than one device out of the rack cabinet at the same time.
vRemove the rack doors and side panels to provide easier access during installation.
vConnect the server to a properly grounded outlet.
vDo not overload the electrical outlet when you install multiple devices in the rack cabinet.
vInstall 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.

According to the length between the front post and
the rear post of the rack, adjust the length of rail by
moving the rear bracket of the rail 1 until the
pins at the front and rear of the brackets click into
the holes in the rack posts. When the pins are in
place, install the retaining screws on the front and
rear of the bracket.
Notes:
1. The stretching range of the outer guide rail is
740 mm (29.13 inches) to 910 mm (35.83 inches).
Confirm the size of the rack before the
installation.
2. The left and the right outer guide rails should
be fixed to the left and the right posts of the
rack at the same level.
3. If the holes in the post are square holes, you can
operate according to the above methods.
4. If the holes in the post are round holes, remove
the retaining screws and pins on the front and
rear brackets and install the pins shipped with
guide rails. Then install the retaining screws
shipped with guide rails to secure the guide
rails onto rack.
Place the server on the bearing bracket and push it
inside. While pushing the server, you have to
support the bottom of the server with hands to
avoid the drop of the server.
When the server is in place, install the two retaining
screws on the left and right handles to secure the
server on the rack.
