THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Introduction

CHAP T E R

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

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:

78-16356-01

• Cisco CSS 11500, CSS 11000, or CSS 11150

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

switches

• Cisco LocalDirector

• Cisco IOS SLB

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.

System Hardware Features

Chapter 1 Introduction

1-2

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

• Rear Panel Features

Ports and Connectors

The GSS supports the following port connectors on the rear of the chassis:

• Console Port

• Ethernet Connectors

Chapter 1 Introduction

Warning

Console Port

To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.

The GSS has one standard RS-232 serial port located on the rear panel that operates as the console port. The integrated serial port uses a 9-pin male D-shell connector. Figure 1-4 shows the pin number assignments for the 9-pin port.

Refer to Table 1 - 3 for the console port connector pinouts.
