Dell PowerConnect 2508: Caution: Safety Instructions (continued)

Caution: Safety Instructions (continued)

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: Installing systems in a rack without the front and side stabilizers

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

under certain circumstances. Therefore, always install the stabilizers before

installing components in the rack.

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 may

result in serious injury.

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

use in a Dell rack cabinet using the customer rack kit. 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 rack

cabinet evaluated for suitability by a certified safety agency. Dell disclaims all

liability and warranties in connection with such combinations.

• System rack kits are intended to be installed in a rack by trained service technicians. If

you install the kit in any other rack, be sure that the rack meets the specifications of a

Dell rack.

CAUTION: Do not move racks by yourself. Due to the height and weight of the

rack, a minimum of two people should accomplish this task.

• 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.

• Make sure that the rack is level and stable before extending a component from the

rack.

• Use caution when pressing the component rail release latches and sliding a

component into or out of a rack; the slide rails can pinch your fingers.

• After a component is inserted into the rack, carefully extend the rail into a locking

position, and then slide the component into the rack.

• 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.
