Accessories and options

Installation of accessories and options in safety interlocked areas should performed only by individuals who are qualified in servicing computer equipment and trained to deal with products capable of producing hazardous energy levels.

Products with casters

Products provided with casters should be moved with care. Quick stops, excessive force, and uneven surfaces may cause the product to overturn.

Hot-pluggable power supplies

Observe the following guidelines when connecting and disconnecting power to the power supplies:

◆Install the power supply before connecting the power cord to the power supply.

◆Unplug the power cord before removing the power supply from the server.

◆If the system has multiple sources of power, disconnect power from the system by unplugging all power cords from the power supplies.

Floor standing products

Be sure the bottom stabilizers on the equipment are installed and fully extended. Ensure that the equipment is properly stabilized and supported before installing options and cards.

Rack-mountable products

Because the rack allows you to stack computer components vertically, you must take precautions to provide for rack stability and safety:

◆Do not move large racks by yourself. Due to the height and weight of the rack, Compaq recommends a minimum of two people to accomplish this task.

◆Before working on the rack, be sure the leveling jacks (feet) extend to the floor and that the full weight of the rack rests on the floor. Also install stabilizing feet on a single rack or join multiple racks together before starting work.

◆Always load the rack from the bottom up, and load the heaviest item in the rack first. This makes the rack bottom-heavy and helps prevent the rack from becoming unstable.

◆Ensure that the rack is level and stable before extending a component from the rack.
