This chapter provides a brief overview of the hardware components described in later chapters and contains these sections:
This section describes the route processor, shown in Figure 1-1.
The route processor resides in slot 4 of the Catalyst 8540 switch chassis. It contains most of the system memory components and the main system processor, which includes the network management processor for the system software. The route processor maintains and executes the management functions that control the device.
The route processor features include the following:
In addition to these features, the route processor performs the following management functions:
The LEDs on the route processor indicate the status of the route processor, Flash PC card slots, and interface ports. (See Figure 1-2.)
The route processor includes one 10BaseT RJ-45 Ethernet port that you can use to connect a management workstation for SNMP management. (See Figure 1-2.)
The route processor includes two Flash PC 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 route processor includes one console port, shown in Figure 1-4.
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 LEDs on the switch module indicate the status of the module. (See Figure 1-5.)
The line modules are used for 10-Mbps, 100-Mbps, or 1000-Mbps Ethernet connections. Status and link LEDs on each port give quick, visual indications of port status and operation. Comprehensive statistics gathering and alarm monitoring capabilities are available for all connections.
All configuration information for line modules is saved between hot swaps and reboots, and interface types are discovered automatically by the Catalyst 8540 CSR. This eliminates mandatory manual configuration.
The Catalyst 8540 CSR supports any line module combination. You can configure it with only the number and type of interfaces required, with up to 128 interface ports.
The 10/100BaseT Ethernet line module has 16 10-Mbps or 100-Mbps Layer 2 or Layer 3 unshielded twisted-pair (UTP) connections. (See Figure 1-6.) 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 1-7.) This module supports full-duplex or half-duplex connections and Fast EtherChannel operation. It provides 16 multimode fiber ports with MT-RJ connectors.
The Gigabit Ethernet line module is used for 1000-Mbps Layer 2 or Layer 3 fiber-optic connections. (See Figure 1-8.) It provides two Gigabit Ethernet ports with SC-type connectors.
