Dell™ Rack Installation Guide 5

Safety Instructions

Use the following safety guidelines to ensure your own personal safety

and to help protect your system and working environment from potential

damage. For complete safety information, see the Product Information Guide.

SAFETY: Rack Mounting of Systems

Observe the following precautions for rack stability and safety.

Systems are considered to be components in a rack. Thus, “component”

refers to any system as well as to various peripherals or supporting hardware.

CAUTION: Before installing systems in a rack, install the front and side

stabilizers on stand-alone (single) racks or the front stabilizer on racks joined

to other racks. Failure to install stabilizers accordingly before installing systems

in a rack could cause the rack to tip over, potentially resulting in bodily injury

under certain circumstances. Therefore, always install the stabilizer(s) before

installing components in the rack.

CAUTION: After installing system/components in a rack, never pull more than one

component out of the rack on its slide assemblies at one time. The weight of more

than one extended component could cause the rack to tip over and cause injury.

NOTE: Your system is safety-certified as a free-standing unit and as a component

for use in a rack cabinet using the customer rack kit when both the rack cabinet

and rack kit were designed for your system. The installation of your system and rack

kit in any other rack cabinet has not been approved by any safety agencies. It is

your responsibility to have the final combination of system and rack kit in a cabinet

evaluated for suitability by a certified safety agency. The manufacturer disclaims

all warranties and liability in connection with such combinations.

• System rack kits are intended to be installed in an approved rack by

trained service technicians. If you install the kit in any other rack,

be sure that the rack meets the specifications.

• Before working on the rack, make sure that the stabilizers are secured

to the rack, extended to the floor, and that the full weight of the rack

rests on the floor. Install front and side stabilizers on a single rack or

front stabilizers for joined multiple racks before working on the rack.

• Always load the rack from the bottom up, and load the heaviest item

in the rack first.
