This chapter provides a brief overview of the hardware components described in later chapters. It includes the following sections:
This section describes the switch route processor, shown in Figure 1-1.
The switch route processor card resides in slot 2 of the Catalyst 8510 switch chassis or in slot 13 of the Catalyst 5500 switch chassis. This card contains most of the system memory components and the main system processor, which includes the Ethernet Layer 2 and Layer 3 switching engine and network management processor for the system software. The switch route processor maintains and executes the management functions that control the device.
The switch route processor features include the following:
In addition to these features, the switch route processor performs the following management functions:
The LEDs on the switch route processor indicate the status of the switch route processor, the fan assembly, and the power supplies. (See Figure 1-2.)
The reset switch is at the left side of the switch route processor faceplate, in a small hole between two columns of LEDs. You can use the reset switch when a software-initiated reset is not possible. (See Figure 1-2.)
The switch route processor includes one RJ-45 Ethernet port that you can use to connect a management workstation for SNMP management. (See Figure 1-2.)
The switch route processor includes two PCMCIA card slots into which you can install up to two Type II Flash memory cards. (See Figure 1-3.) You can store the system software and configuration information on these cards. You can also configure the system to boot from a software image stored on a Flash memory card.
For detailed descriptions of the Flash memory cards, refer to the section "Installing and Removing Flash Memory Cards" in the chapter "Installing and Connecting Components."
The switch route processor includes one auxiliary port (labeled AUX) and one console port (labeled CONSOLE), shown in Figure 1-4.
The auxiliary port is a male EIA/TIA-232 data terminal equipment (DTE) DB-25 plug, used for connection to a modem.
The console port is a female EIA/TIA-232 data communications equipment (DCE), DB-25 receptacle, used for connection to a console terminal or modem.
The Catalyst 8510 line modules are used for 10, 100, or 1000 Mbps Ethernet connections. Comprehensive network management, statistics gathering, and alarm monitoring capabilities are available. Status and link LEDs on each port give quick, visual indications of port status and operation.
All configuration information for line modules is saved between hot swaps and device reboots, while interface types are discovered automatically by the device. This eliminates mandatory manual configuration.
The Catalyst 8510 supports any line module combination. You can configure your devices with the number and type of interfaces required, with up to 32 interface ports.
The 10/100BaseT Ethernet line module has eight ports and is used for 10-Mbps or 100-Mbps Layer 2 or Layer 3 unshielded twisted-pair (UTP) connections. (See Figure 1-5.) This module supports full-duplex or half-duplex connections and Fast EtherChannel operation.
The 100BaseFX multimode fiber Ethernet line module is used for 100-Mbps Layer 2 or Layer 3 fiber-optic connections. (See Figure 1-6.) This module supports full-duplex or half-duplex connections and Fast EtherChannel operation. It provides eight multimode fiber ports with SC-type connectors.
The Gigabit Ethernet line module is used for 1000-Mbps Layer 2 or Layer 3 fiber-optic connections. (See Figure 1-7.) It provides one Gigabit Ethernet port with an SC-type connector.
