Cisco Global Site Selector 4491 Hardware Installation Guide

78-16356-01

Introduction

This chapter provides a basic functional overview of the Cisco Global Site

Selector 4491 (GSS) and describes the hardware, major components, and front

and rear panel indicators and controls.

This chapter contains the following major sections:

•Introduction

•System Hardware Features

•Ports and Connectors

Introduction

The GSS is a networking product that provides site selection services that are

critical for disaster recovery deployments involving Internet and intranet data

centers. The GSS globally load balances traffic between geographically

distributed data centers managed by other server load balancers (SLBs), such as:

•Cisco CSS 11500, CSS 11000, or CSS 11150

•Cisco Content Switching Module (CSM) for the Catalyst 6500 series

switches

•Cisco LocalDirector

•Cisco IOS SLB

Chapter 1 Introduction

System Hardware Features

1-2

Cisco Global Site Selector 4491 Hardware Installation Guide

78-16356-01

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.

System Hardware Features

The GSS is designed for AC-input power and has a single AC-input power supply.

The GSS includes:

•An integrated dual-port Ethernet controller that provides an interface for

connecting to 10-Mbps, 100-Mbps, or 1000-Mbps networks.

•Two 10BASE-T/100BASE-TX/1000BASE-TX Ethernet ports with RJ-45

receptacles.

Both Ethernet ports support autonegotitate, full-duplex, or half-duplex operation

on an Ethernet LAN.

This section includes the following topics:

•Front Panel Features

current rating of the cable should be greater than the ratings marked on the

product.

•To help prevent electric shock, plug the GSS, components, and peripheral

power cables into properly grounded electrical outlets. These cables are

equipped with three-prong plugs to help ensure proper grounding. Do not use

adapter plugs or remove the grounding prong from a cable.

•Observe power strip ratings. Make sure that the total ampere rating of all

products plugged into the power strip does not exceed 80% of the rating.

•To help protect your GSS and components from sudden, transient increases

and decreases in electrical power, use a surge suppressor, line conditioner, or

uninterruptible power supply (UPS).

•Do not modify power cables or plugs. Consult a licensed electrician or your

power company for site modifications. Always follow your local and national

wiring rules.

Protecting Against Electrostatic Discharge

Static electricity can harm delicate components inside your computer. To prevent

static damage, discharge static electricity from your body before you touch any of

your computer’s electronic components, such as the microprocessor. You can do

so by touching an unpainted metal surface on the computer chassis.

As you continue to work inside the computer, periodically touch an unpainted

metal surface to remove any static charge your body may have accumulated.

You can also take the following steps to prevent damage from electrostatic

discharge (ESD):

•When unpacking a static-sensitive component from its shipping carton, do not

remove the component from the antistatic packing material until you are

ready to install the component in your computer. Just before unwrapping the

antistatic packaging, be sure to discharge static electricity from your body.

•When transporting a sensitive component, first place it in an antistatic

container or packaging.

•Handle all sensitive components in a static-safe area. If possible, use

antistatic floor pads and workbench pads.

Chapter 2 Preparing for Installation

Preparing Your Site for Installation

Environmental

When planning your site layout and equipment locations, remember the

precautions described in this section to help avoid equipment failures and reduce

the possibility of environmentally caused shutdowns. If you are experiencing

shutdowns or unusually high errors with your existing equipment, these

precautions will help you isolate the cause of failures and prevent future

problems.

Use the following precautions when planning the operating environment for your

GSS.

•Always follow the ESD-prevention procedures described in the “Protecting

Against Electrostatic Discharge”section to avoid damage to equipment.

Damage from static discharge can cause immediate or intermittent equipment

failure.

•Make sure that the chassis cover is secure. The chassis allows cooling air to

flow effectively within it. An open chassis allows air leaks, which could

interrupt and redirect the flow of cooling air from internal components.

•Electrical equipment generates heat. Ambient air temperature might not be

adequate to cool equipment to acceptable operating temperatures without

adequate circulation. Make sure that the room in which you operate has

adequate air circulation.

Choosing a Site for Installation

Warning

This unit is intended for installation in restricted access areas. A restricted

access area is where access can only be gained by service personnel through

the use of a special tool, lock and key, or other means of security, and is

controlled by the authority responsible for the location.

•Choose a site with a dry, clean, well-ventilated and air-conditioned area.

•Choose a site that maintains an ambient temperature of 10° to 35°C

(50° to 95°F).

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.

Chapter 5 Maintaining Your GSS

Maintaining Your Site Environment

5-2

Cisco Global Site Selector 4491 Hardware Installation Guide

78-16356-01

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

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:

•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.

5-3

Cisco Global Site Selector 4491 Hardware Installation Guide

78-16356-01

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.

•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.

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.

Altitude

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.

Chapter 5 Maintaining Your GSS

Maintaining Your Site Environment

5-4

Cisco Global Site Selector 4491 Hardware Installation Guide

78-16356-01

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.

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.

5-5

Cisco Global Site Selector 4491 Hardware Installation Guide

78-16356-01

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.

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.

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.

•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

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.

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.

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.

Chapter 5 Maintaining Your GSS

Using Power Protection Devices

5-8

Cisco Global Site Selector 4491 Hardware Installation Guide

78-16356-01

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.
