C H A P T E R 5 Maintaining the Cisco Global Site Selector 4490 Proper use of preventive maintenance procedures can keep the Cisco Global Site Selector 4490 in top operating condition and minimize the need for costly, time-consuming service procedures. This chapter contains maintenance procedures that you should perform regularly.
Chapter 5 Maintaining the Cisco Global Site Selector 4490 Maintaining Your Site Environment This section discusses various environmental factors that can adversely affect system performance and longevity.
Chapter 5 Maintaining the Cisco Global Site Selector 4490 Maintaining Your Site Environment Adequate ventilation is particularly important at high altitudes. System performance may not be optimum when the system is operating at high temperatures as well as high altitudes. • Make sure that all slots and openings on the system remain unobstructed, especially the fan vent on the back of the system.
Chapter 5 Maintaining the Cisco Global Site Selector 4490 Maintaining Your Site Environment Dust and Particles A clean operating environment can greatly reduce the negative effects of dust and other particles, which act as insulators and interfere with the operation of a system’s mechanical components. Also, in addition to regular cleaning, you should follow these guidelines to deter contamination of the system equipment: • Do not permit smoking anywhere near the system.
Chapter 5 Maintaining the Cisco Global Site Selector 4490 Maintaining Your Site Environment To reduce the effects of ESD, you should 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 the Cisco Global Site Selector 4490 Maintaining Your Site Environment Magnetism Because they store data magnetically, hard disk drives are extremely susceptible to the effects of magnetism. Hard disk drives should never be stored near magnetic sources such as the following: • Monitors • TV sets • Printers • Telephones with real bells • Fluorescent lights Power Source Interruptions Systems are especially sensitive to variations in voltage supplied by the AC power source.
Chapter 5 Maintaining the Cisco Global Site Selector 4490 Using Power Protection Devices – Adding machines – Laser printers – Facsimile machines – Any other motorized equipment Besides these appliances, the greatest threats to a system’s supply of power are surges or blackouts caused by electrical storms. Whenever possible, turn off the system and any peripherals and unplug them from their power sources during thunderstorms.
Chapter 5 Maintaining the Cisco Global Site Selector 4490 Using Power Protection Devices Line Conditioners Line conditioners go beyond the overvoltage protection of surge protectors. Line conditioners keep a system’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.
