C H A P T E R 5 Maintaining Your GSS Proper use of preventive maintenance procedures can keep the GSS in top operating condition and minimize the need for time-consuming service procedures. This chapter contains maintenance procedures that you should perform regularly.
Chapter 5 Maintaining Your GSS Maintaining Your Site Environment This section discusses various environmental factors that can adversely affect GSS performance and longevity.
Chapter 5 Maintaining Your GSS Maintaining Your Site Environment Adequate ventilation is particularly important at high altitudes. GSS performance may not be optimum when operating at high temperatures as well as high altitudes. • Ensure that all slots and openings on the GSS remain unobstructed, especially the fan vent on the back of the GSS. • Clean the GSS at regular intervals to avoid any buildup of dust and debris, which can cause it to overheat.
Chapter 5 Maintaining Your GSS Maintaining Your Site Environment Dust and Particles A clean operating environment can greatly negate the effects of dust and other particles, which act as insulators and interfere with the operation of mechanical components.
Chapter 5 Maintaining Your GSS Maintaining Your Site Environment To reduce the effects of ESD, observe the following guidelines: • Wear a grounding wrist strap. If a grounding wrist strap is unavailable, touch an unpainted metal surface on the chassis periodically to neutralize any static charge. • Keep components in their antistatic packaging until they are installed. • Avoid wearing clothing made of wool or synthetic materials.
Chapter 5 Maintaining Your GSS Maintaining Your Site Environment Magnetism Because they store data magnetically, hard disk drives are extremely susceptible to the effects of magnetism. D not store hard disk drives near magnetic sources such as: • Monitors • TV sets • Printers • Telephones with real bells • Fluorescent lights Power Source Interruptions The GSS is especially sensitive to variations in voltage supplied by the AC power source.
Chapter 5 Maintaining Your GSS Using Power Protection Devices – Adding machines – Laser printers – Facsimile machines – Any other motorized equipment In addition to these appliances, the greatest threats to the GSS power supply are surges or blackouts caused by electrical storms. Whenever possible, turn off the GSS and any peripherals and unplug them from their power sources during thunderstorms.
Chapter 5 Maintaining Your GSS Using Power Protection Devices Line Conditioners Line conditioners go beyond the overvoltage protection of surge protectors. Line conditioners keep a GSS’s AC power source voltage at a fairly constant level and therefore can handle brownouts. Because of this added protection, line conditioners cost more than surge protectors—up to several hundred dollars. However, these devices cannot protect against a complete loss of power.
