System Hardware Features

The GSS is the cornerstone of disaster recovery in such distributed deployments and enables businesses to confidently deploy global Internet and intranet applications with the knowledge that users will be quickly routed to standby data centers should problems occur.

The GSS is deployed at strategic locations within your network. The GSS performs two major functions when deployed with other SLBs by:

• Taking an active role in the domain name server (DNS) infrastructure,

connecting clients to SLBs that support the requested website.

• Continuously monitoring the load and availability of SLBs in its network,

selecting the SLB that is most able to answer each client request.

By off-loading DNS resolution from traditional DNS servers, the GSS optimizes global site selection and increases DNS responsiveness. The GSS increases the fault tolerance and scalability of large websites and data centers through its monitoring of load and availability.

Establishing a Serial Console Connection

Before you configure the GSS, you should establish a serial console connection to it. This requires a PC, two DB-9 to RJ-45 adapters (provided), an RJ-45 cable (provided), and terminal emulation communication software (Hyper Terminal or equivalent). You may also use a serial concentrator connection, if desired.

To establish a serial console connection:

1. Connect a console to the serial console port on the rear panel: a. Attach a DB-9 to RJ-45 adapter to the serial port of the console. b. Attach a DB-9 to RJ-45 adapter to the serial port of the GSS. For the

location of the serial port, see Figure 3-10.

c. Use an RJ-45 cable to connect the console to the GSS.

2. If you have not already done so, power up the GSS as described in the

“Booting the GSS” section.

3. Open your terminal emulation application on your PC to access the GSS CLI.

The following procedure uses HyperTerminal for Windows:

a. Launch HyperTerminal. The Connection Description window appears.

3-18

b. Enter a name for your session in the Name field. c. Click OK. The Connect To window appears. d. From the drop-down list, choose the COM port to which the device is

connected.

e. Click OK. The Port Properties window appears.

f. Set the port properties:

Baud Rate = 9600

Data Bits = 8

Flow Control = none

Chapter 3 Installing the GSS

4. Once you create a session, choose Save As from the File menu to save the

connection description. Saving the connection description has the following two advantages:

–

The next time you launch HyperTerminal, the session is listed as an option under Start > Programs > Accessories > HyperTerminal > Name_of_session. This option lets you reach the CLI prompt directly without repeating the configuration steps.

–

You can connect your cable to a different device without configuring a new HyperTerminal session. If you use this option, ensure that you connect to the same port on the new device as was configured in the saved HyperTerminal session. Otherwise, a blank screen appears without a prompt.

CHAP T E R

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.

This chapter includes the following major sections:

• Maintaining Your Site Environment

• Using Power Protection Devices

Maintaining Your Site Environment

An exhaust fan in the power supply cools the power supply and GSS by drawing air in through various openings and blowing it out the back panel. However, the fan may also draws dust and other particles into the GSS, causing contaminant buildup, which results in an increase in the GSS’s internal temperature and interferes with the operation of various GSS components.

To avoid these conditions, we recommend keeping your work environment clean to reduce the amount of dust and dirt around the GSS, thereby reducing the amount of contaminants drawn into it by the power supply fan.

Maintaining Your Site Environment

Temperature

Chapter 5 Maintaining Your GSS

This section discusses various environmental factors that can adversely affect GSS performance and longevity. It covers:

• Temperature

• Humidity

• Altitude

• Dust and Particles

• Corrosion

• Electrostatic Discharge

• Electromagnetic and Radio Frequency Interference

• Magnetism

• Power Source Interruptions

Temperature extremes can cause a variety of problems, including premature aging and failure of chips or mechanical failure of devices. Extreme temperature fluctuations can cause chips to become loose in their sockets and cause expansion and contraction of disk drive platters, resulting in read or write data errors.

To minimize the negative effects of temperature on GSS performance, follow these guidelines:

5-2

• Ensure that the GSS is operated in an environment no colder than 32°F (0°C)

or hotter than 104°F (40°C).

• Ensure that the GSS has adequate ventilation. Do not place it within a

closed-in wall unit or on top of cloth, which can act as insulation. Do not place it in direct sunlight. Do not place it next to a heat source of any kind, including heating vents during winter.

Cisco Global Site Selector 4491 Hardware Installation Guide

78-16356-01

Page 71

Chapter 5 Maintaining Your GSS

Adequate ventilation is particularly important at high altitudes. GSS performance may not be optimum when operating at high temperatures as well as high altitudes.

Humidity

High-humidity conditions can cause moisture in the GSS. This moisture can cause corrosion of internal components and degradation of properties such as electrical resistance, thermal conductivity, physical strength, and size. Extreme moisture buildup inside the GSS can result in electrical shorts, which can cause serious damage.

Each GSS is rated to operate at 8 to 80 percent relative humidity, with a humidity gradation of 10 percent per hour. Buildings in which climate is controlled by air conditioning in the warmer months and by heat during the colder months usually maintain an acceptable level of humidity for the GSS. However, if a GSS is located in an unusually humid location, use a dehumidifier to maintain the humidity within an acceptable range.

Maintaining Your Site Environment

• 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.

• If the GSS has been exposed to abnormally cold temperatures, allow a 2-hour

warm-up period to bring it up to normal operating temperature before turning it on. Failure to do so may cause damage to internal components, particularly the hard disk drive.

Altitude

78-16356-01

Operating a GSS at high altitude (low pressure) reduces the efficiency of forced and convection cooling and can result in electrical problems related to arcing and corona effects. This condition can also cause sealed components with internal pressure, such as electrolytic capacitors, to fail or perform at reduced efficiency.

Cisco Global Site Selector 4491 Hardware Installation Guide

Page 72

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. Also, in addition to regular cleaning, follow these guidelines to deter contamination of the GSS equipment:

• Do not permit smoking anywhere near the GSS

• Do not permit food or drink near the GSS

• Use dust covers when the GSS is not in use

• Close windows and outside doors to keep out airborne particles

Corrosion

The oil from a person’s fingers or prolonged exposure to high temperature or humidity can corrode the gold-plated edge connectors and pin connectors on various devices in the GSS. This corrosion on GSS connectors is a gradual process that can eventually lead to intermittent failures of electrical circuits.

Chapter 5 Maintaining Your GSS

To prevent corrosion, avoid touching contacts on boards and cards. Protecting the GSS from corrosive elements is especially important in moist and salty environments, which tend to promote corrosion. Also, as a further deterrent to corrosion, the GSS should not be used in extreme temperatures, as explained in the “Temperature” section.

Electrostatic Discharge

Electrostatic discharge (ESD) results from the buildup of static electricity on the human body and certain other objects. Static electricity is often produced by simple movements such as walking across a carpet. ESD is a discharge of a static electrical charge that occurs when a person whose body contains such a charge touches a component in the GSS, especially chips, and causes the component to fail.

ESD is a problem particularly in dry environments where the relative humidity is below 50 percent.

Cisco Global Site Selector 4491 Hardware Installation Guide

5-4

78-16356-01

Page 73

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.

Electromagnetic and Radio Frequency Interference

Electromagnetic interference (EMI) and radio frequency interference (RFI) can adversely affect devices such as radio and television (TV) receivers operating near the GSS. Radio frequencies emanating from the GSS can also interfere with cordless and low-power telephones. Conversely, RFI from high-power telephones can cause spurious characters to appear on a monitor screen.

RFI is defined as any EMI with a frequency above 10 kHz. This type of interference can travel from the GSS to other devices through the power cable and power source or through the air like transmitted radio waves. The Federal Communications Commission (FCC) publishes specific regulations to limit the amount of EMI and RFI emitted by computing equipment. Each GSS meets these FCC regulations.

78-16356-01

To reduce the possibility of EMI and RFI, follow these guidelines:

• Operate the GSS only with its cover installed.

• Ensure that the screws on all peripheral cable connectors are securely

fastened to their corresponding connectors on the back of the GSS.

• Always use shielded cables with metal connector shells for attaching

peripherals to the 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. Overvoltage, undervoltage, and transients (or spikes) can erase data from memory or even cause components to fail. To protect against these types of problems, always properly ground power cables. Use one or both of the following methods:

• Use one of the power protection devices described in the “Using Power

Protection Devices” section.

Chapter 5 Maintaining Your GSS

5-6

• Place the GSS on a dedicated power circuit (rather than sharing a circuit with

other heavy electrical equipment). In general, do not allow the GSS to share a circuit with any of the following equipment:

–

Copier machines

–

Air conditioners

–

Vacuum cleaners

–

Space heaters

–

Power tools

–

Teletype machines

Chapter 5 Maintaining Your GSS

–

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.

If a blackout occurs—even a temporary one—while the GSS is turned on, turn it off immediately and disconnect it from the electrical outlet. Leaving the GSS on may cause problems when the power is restored; all other appliances left on in the area can create large voltage spikes that can damage the GSS.

Using Power Protection Devices

A number of devices are available that protect against power problems such as power surges, transients, and power failures. The following subsections describe some of these devices.

Using Power Protection Devices

Surge Protectors

Surge protectors are available in a variety of types and usually provide a level of protection commensurate with the cost of the device. Surge protectors prevent voltage spikes, such as those caused during an electrical storm, from entering a GSS through the electrical outlet. Surge protectors, however, do not offer protection against brownouts, which occur when the voltage drops more than 20 percent below the normal AC line voltage level.

78-16356-01

Cisco Global Site Selector 4491 Hardware Installation Guide

5-7

Page 76

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.

Uninterruptible Power Supplies

Uninterruptible power supply (UPS) systems offer the most complete protection against variations in power because they use battery power to keep the GSS running when AC power is lost. The battery is charged by the AC power while it is available, so once AC power is lost, the battery can provide power to the GSS for a limited amount of time—from 15 minutes to an hour or so—depending on the UPS system.

Surge protectors should be used with all UPS systems, and the UPS system should be Underwriters Laboratories (UL) safety-approved.
