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.

– 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.

Use safe practices when lifting.

≥18 kg (39.7 lb) ≥32 kg (70.5 lb) ≥55 kg (121.2 lb)

Do not place any object on top of

rack-mounted devices.

Remove the left and right guide rail components from the package. The illustration below shows the

components of the right guide rail. The components of the left guide rail are the same as those of the

right.

1 Retaining screw for the front bracket

2 Pin on the front bracket

3 Front bracket

4 Bearing bracket

5 Rear bracket

Remove the retaining screws on the front and rear

brackets.

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.

To remove the server from the rack, reverse these instructions. Store this information with your server

documentation for future use.
