1-U Keyboard Tray Installation
NOTE:
One unit, or U, equals 1.75 vertical inches.
This guide provides instructions for installing and using the Dell PowerEdge™ 1-U keyboard tray in
a four-post rack cabinet. The pullout tray assembly accommodates a keyboard with a trackball.
An attached cable-management arm routes the keyboard/trackball cables to the back of the rack.
Important Safety Information
Observe the following safety precautions when installing components in the rack:
CAUTION:
You must strictly follow the procedures in this document to protect yourself as well as
others who may be involved. Your system may be very large and heavy and proper preparation and
planning are important to prevent injury to yourself and to others. This becomes increasingly important
when systems are installed high up in the rack.
CAUTION:
Rack cabinets can be extremely heavy and move easily on their casters. They have no
brakes. Use extreme caution while moving the rack cabinet. Retract the leveling feet when relocating
the rack cabinet. Avoid long or steep inclines or ramps where loss of cabinet control may occur. Extend
the leveling feet for support and to prevent the cabinet from rolling.
CAUTION:
Installing components in a rack without the front and side stabilizer feet installed and
anchored to the floor could cause the rack to tip over, potentially resulting in bodily injury under certain
circumstances. Therefore, always install and anchor the stabilizer feet before installing components in
the rack.
Recommended Tools and Supplies
You may need the following to install the system in a four-post rack:
• Masking tape or a felt-tip pen, for use in marking the mounting holes to be used
Keyboard Tray Kit Contents
The keyboard tray kit includes the following items. See Figure 1-1.
• One 1-U keyboard tray with cable-management arm installed
NOTE:
A keyboard is not shipped preinstalled in the tray. You must order a separate Dell rack-mount
keyboard to complete the installation.
• Do not overload the AC supply branch circuit that provides power to the rack. The total
rack load should not exceed 80 percent of the branch circuit rating.
• Ensure that proper airflow is provided to components in the rack.
• Do not step on or stand on any component when servicing other components in a rack.
