Product Overview

Product Overview

This chapter describes the multiservice switch route processor and ATM switch processor, which are referred to generically as the processor card. This card contains the main system processor, which includes the ATM switching engine and network management processor for the system software and most of the system memory components. The processor card maintains and executes the management functions that control the system. You can install the processor card shown in Figure 1-1 in slots 4 and 8 of the Catalyst 8540 MSR chassis.

for the Catalyst 8540 MSR

You can install the processor card shown in Figure 1-2 in the following systems:

  • Slot 2 of the Catalyst 8510 MSR chassis

  • Slot 13 of the Catalyst 5500 switch chassis

  • Slot 2 of the LightStream 1010 ATM switch chassis

and LightStream 1010 ATM Switch

This chapter describes the processor card features in the following sections:

Management Ports

The processor card includes one RJ-45 Ethernet port that you can use to connect a management workstation for SNMP management.

The auxiliary port (labeled AUX) is a male Electronics Industries Association/Telecommunications Industry Association (EIA/TIA)-232, data terminal equipment (DTE), DB-25 plug used for connection to a modem. (See Figure 1-3.)

Note The auxiliary port is not available on the Catalyst 8540 MSR processor card.

The console port (labeled CONSOLE) is a female, EIA/TIA-232, data communications equipment (DCE), DB-25 receptacle used for connection to a console terminal or modem. (See Figure 1-3.)

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

Network Clock Module

The Catalyst 8540 MSR processor card provides simple multiplexers and controls to generate and distribute network clocks to all port adapters and interface modules. For a higher level of network clocking, an optional network clock module may be installed.
(See Figure 1-4.)

Note The network clock module is available only for the Catalyst 8540 MSR
processor card.

Clock Module on the Catalyst 8540 MSR Processor Card

Refer to the ATM Switch Router Software Configuration Guide for information about network clocking and how to configure a network clock.

Flash PC Card Slots

The processor card has two Flash PC Card slots into which you can install up to two Type II Flash PC Cards. (See Figure 1-5.) 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 the Flash PC Card.

Note For detailed descriptions of the Flash PC Card, see the "Installing and Removing Flash PC Cards" section.

LEDs

The LEDs on the processor card indicate the status of the processor card, fan assembly, and power supplies. (See Figure 1-6.)

Note For detailed descriptions of the processor card LEDs, see the "Processor Card LEDs" section.

Reset Switch

The reset switch (labeled RESET) is located on the left side of the processor card faceplate, through a small hole between two columns of LEDs. You can use the reset switch when a software-initiated reset is not possible.

DRAM SIMMs

There are two dynamic random-access memory (DRAM) single in-line memory modules (SIMMs) on the processor card to store incoming and outgoing packets, queues, and caches (32-MB default for the feature card per class queuing [FC-PCQ] or 64-MB default for the feature card per flow queuing [FC-PFQ]).

Flash Memory SIMM

With the Flash memory SIMM, you can 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.

Feature Card

The feature card (see Figure 1-7) is a daughter card on the processor card that provides a number of value-added features in addition to the basic switch functionality.

Note Feature cards are not used on the Catalyst 8540 MSR processor card.

FC-PCQ and FC-PFQ

There are two types of feature cards: feature card per class queuing (FC-PCQ) and feature card per flow queuing (FC-PFQ). FC-PCQ provides a subset of the ATM Forum traffic management features provided by FC-PFQ, as described in Table 1-1.
