This chapter provides a basic functional overview of the Global Site Selector 4480 (GSS-4480-K9) and describes the Global Site Selector 4480 hardware, major components, and front and back panel indicators and controls.
This chapter contains the following sections:
Cisco Global Site Selectors (GSSs) are networking products that provide 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 Content Services Switches and Cisco Content Switching Modules, IOS-SLBs, and Cisco LocalDirectors. 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 Global Site Selector 4480 is deployed at strategic locations within your network. The GSS performs two major functions when deployed with other SLBs:
By off-loading Domain Name System (DNS) resolution from traditional DNS servers, the GSS optimizes global site selection and increases DNS responsiveness. Through its monitoring of load and availability, the GSS increases the fault tolerance and scalability of large websites and data centers.
The Global Site Selector 4480 is configured for AC-input power. The default factory configuration comes with one power supply installed. The Content Router 4480 has one internal 36-gigabyte (GB) Ultra2 LVD SCSI hard drive. For network connections, the Global Site Selector 4480 has two 10/100BASE-T Ethernet/Fast Ethernet ports with RJ-45 receptacles. Port Ethernet 0 supports autodetect speed mode and full-duplex operation.
Table 1-1 lists the storage and memory specifications for the Global Site Selector 4480.
Figure 1-1 shows the Global Site Selector 4480 front panel. Figure 1-2 shows the rear panel with one AC power supply.
Table 1-2 describes the front and back panel ports and receptacles. (See the front panel in Figure 1-1 and the back panel in Figure 1-2.)

Warning 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. |
Table 1-3 describes the LEDs on the front panel.

This section describes the cables and connectors that connect your Global Site Selector 4480 to a terminal and to the external network.
The Global Site Selector 4480 comes with a console cable kit that includes the following cable and adapters:
Use the rollover cable to connect the Global Site Selector 4480 console port to the COM port of an ASCII terminal or a PC running terminal emulation software. The console port on the Global Site Selector 4480 is configured as data terminal equipment (DTE) and uses an RJ-45 connector.
By attaching an RJ-45 to DB-9 adapter to the rollover cable, you create an RJ-45 to DB-9 null modem cable.
You can identify a rollover cable by comparing the two modular ends of the cable, as shown in Figure 1-3. Holding the cable ends in your hands side by side with the tab at the back, the wire connected to the pin on the outside of the left connector (pin 1) should be the same color as the pin on the outside of the right connector (pin 8).
An Ethernet cable is required to connect the Global Site Selector 4480 to your network. To connect the Global Site Selector 4480 to your network, you must use one of the following types of cables:
 |
Note The Ethernet ports on the Global Site Selector 4480 are MDI. |
Use a Category 5 UTP cable to connect to a 100BASE-T network.
The following pinout information for common cable configurations can assist you in purchasing or building replacement cables.
Table 1-4 shows the pinout for a straight-through 100BASE-T cable.
Table 1-5 shows the pinout for a crossover 100BASE-T cable.
Table 1-6 lists hardware specifications for the Global Site Selector 4480 hardware.
