Component Overview

Component Overview

This chapter provides a brief overview of the hardware components described in this guide and includes the following sections:

The Catalyst 8510 CSR is a five-slot, modular chassis with dual, fault-tolerant, load-sharing AC or DC power supplies. The slots in the chassis are numbered 0 to 5. Slot 2 is reserved for the route processor. The remaining slots are reserved for interface modules. The system allows for redundant power supplies and supports wirespeed Layer 2/Layer 3 operation. (See Figure 1-1).

Route Processor

Figure 1-2 shows the route processor card, which resides in slot 2 of the Catalyst 8510 chassis or in slot 13 of the Catalyst 5500 chassis. The 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 route processor card maintains and executes the management functions that control the device.


Figure 1-2: Route Processor Card


The route processor card features include the following:

In addition to these features, the route processor performs the following management functions:

Flash Memory SIMM

Use the Flash memory SIMM to load and store system software images remotely. You can download a new software image over the network or from a local server and add the new image to Flash memory or replace an existing image.

LEDs

The LEDs on the route processor indicate the status of the route processor, the fan assembly, and the power supplies. (See Figure 1-3.)

Note For detailed descriptions of the route processor LEDs, see the "Route Processor LEDs" section.

Reset Switch

The reset switch is at the left side of the route processor faceplate, in a small hole between two columns of LEDs. Use the reset switch when a software-initiated reset is not possible. (See Figure 1-3.)

Ethernet Port

The route processor includes one RJ-45 Ethernet port that you can use to connect a management workstation for SNMP management. (See Figure 1-3.)

Note The Ethernet port on the route processor cannot be used as a
routed port.

Flash PC Card Slots

The route processor includes two Flash PC Card slots into which you can install up to two Type II Flash PC Cards. (See Figure 1-4.) 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 PC Card.

Auxiliary and Console Ports

The route processor includes one auxiliary port (labeled AUX) and one console port (labeled CONSOLE), shown in Figure 1-5.

The auxiliary port is a male EIA/TIA-232 DTE DB-25 plug, used for connection to a modem.

The console port is a female EIA/TIA-232 DCE, DB-25 receptacle, used for connection to a console terminal or modem.

Note EIA/TIA-232 and EIA/TIA-449 were known as recommended standards RS-232 and RS-449 before their acceptance as standards by the Electronic Industries Alliance (EIA) and Telecommunications Industry Association (TIA).

Interface Modules

This section briefly describes the interface modules for the Catalyst 8510 CSR chassis. Interface modules provide ports for connection to network services.You can install one interface module in slot 0, slot 1, slot 3, or slot 4 of the chassis. Slot 2 is reserved for the route processor card.

The interface modules are used for 10-Mbps, 100-Mbps, 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 interface modules is saved between hot swaps and device reboots, while interface types are discovered automatically by the device. This eliminates mandatory manual configuration.

The chassis supports any interface module combination. You can configure your devices with the number and type of interfaces required, with up to 32 interface ports.

10/100BaseT Ethernet UTP

The 10/100BaseT Ethernet interface module has eight ports and supports 10-Mbps or 100-Mbps Layer 2 or Layer 3 unshielded twisted-pair (UTP) connections. (See Figure 1-6.) This module also supports full-duplex or half-duplex connections and Fast EtherChannel operation.

100BaseFX Multimode Fiber

The 100BaseFX multimode fiber Ethernet interface module supports 100-Mbps Layer 2 or Layer 3 fiber-optic connections. (See Figure 1-7.) This module also supports full-duplex or half-duplex connections and Fast EtherChannel operation. It provides eight multimode fiber ports with SC-type connectors.

Gigabit Ethernet

The Gigabit Ethernet interface module supports 1000-Mbps Layer 2 or Layer 3 fiber-optic connections. (See Figure 1-8.) It provides one Gigabit Ethernet port with Gigabit Interface Converter (GBIC) modular transceivers and SC-type connectors. The one-port Gigabit Ethernet interface module is available with either 16K or 64K of memory. This memory is used for routing tables.

ACL Daughter Card

The access control list (ACL) daughter card, shown in Figure 1-9, allows you to create lists for network control and security that filter packet flow into or out of router interfaces.

You can install the ACL daughter card on the following interface modules:

For information about installation of the ACL daughter card, see
the "Removing the Protective Guard" section.
