3.3 | Safety Precautions | |
3.3.1 | Precautions and Instructions | |
| 1. | Be sure the correct power range |
|
| net or power outlet. |
| 2. | Thermal notice: All drive trays (even if they do not contain a hard drive) must be installed |
|
| into the enclosure. Leaving a drive bay or module slot open will greatly affect the airflow |
|
| efficiency within the enclosure, and will consequently lead to system overheating. Keep a |
|
| faulty module in place until you have a replacement unit and you are ready to replace it. |
| 3. | An enclosure without disk drives can weigh over 24 kilograms. Two (2) people are |
|
| required to install or relocate the subsystem. Drives should be removed from the enclo- |
|
| sure before moving the subsystem. |
| 4. | Airflow considerations: The subsystem requires an airflow clearance especially on the |
|
| front and rear. For proper ventilation, a minimum of 2.5cm is required between the front |
|
| of the enclosure and rack cover; a minimum of 5cm is required between the enclosure |
|
| and end of the rack. |
| 5. | Handle the system modules by the retention screws, eject levers, or the module’s metal |
|
| frame/face plate only. Avoid touching the PCB boards and connector pins. |
| 6. | None of the covers or replaceable modules should be removed in order to maintain com- |
|
| pliance with safety, emission, or thermal requirements. |
| 7. | Always secure every enclosure module by its retaining screws or make sure it is held in |
|
| place by its latches. |
| 8. | Always make sure the subsystem has a safe electrical earth connection via power cords |
|
| or chassis ground by the rack cabinet. |
| 9. | Be sure that the rack cabinet in which the subsystem chassis is to be installed provides |
|
| sufficient ventilation channels and airflow circulation around the subsystem. |
| 10. | Provide a soft, clean surface to place your enclosure on before working on it. Servicing |
|
| the enclosure on a rough surface may damage the finish of the chassis. |
| 11. | If it is necessary to transport the subsystem, repackage all drives and replaceable mod- |
|
| ules separately. |
3.3.2 |
| |
| Static electricity can damage the system’s electronic components. To prevent ESD damage to | |
| any of the components, follow these precautions before touching or handling them: | |
| • | Discharge the static electricity accumulated in your body by wearing an |
| • | band. |
| Avoid carpets, plastic, vinyl, and Styrofoam in your work area. | |
| • | Handle all components by holding their edges or metal frames. Avoid touching the |
|
| exposed circuitry on PCB boards and connector pins. |
