In addition to the general precautions described earlier in this section, be sure to observe the following precautions when operating server and network products. Failure to observe these precautions could result in fire, bodily injury, and damage to the equipment.

Safety Interlocks and Enclosures
To prevent access to areas containing hazardous energy levels, some servers are provided with enclosures and safety interlocks. Many Compaq servers are interlocked so that the power supply is disabled when the enclosure cover is removed. For servers provided with safety interlocks, observe the following precautions: |
| |  |
Do not remove enclosure covers or attempt to defeat the safety interlocks. |
| | |
Do not repair accessories and options inside enclosed or interlocked areas of the system. Repair should be performed only by individuals who are qualified in servicing computer equipment and trained to deal with products capable of producing hazardous energy levels. |
|
Accessories and Options
Installation of accessories and options in safety interlocked areas should be 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. |
| | |
Extend only one component at a time. The rack may become unstable if more than one component is extended. |
| | |
Use caution when pressing the component rail release latches and sliding a component into the rack. The slide rails could pinch your fingers. |
| | |
Do not overload the AC supply branch circuit that provides power to the rack. The total rack load should not exceed 80% of the branch circuit rating. |
