Cabling the CSS 11501

A CSS 11501 is a fully integrated platform, delivering transport and application (layers 4-7) services for Internet and Intranet data centers. The CSS 11501 is a single-rack-unit, with 6-Gbps aggregate throughput. The integrated components in the CSS 11501 contribute to the overall processing and memory needs for flow set up and flow forwarding.

The fully integrated CSS 11501 is responsible for the following functions:

System powerup and boot control

Centralized routing table management

System-wide connection management

An interface to an external Network Management Station

Disk management

An external RS-232 interface

The CSS 11501 configuration supports:

288 MB RAM memory (256 MB of usable memory)

Two PCMCIA slots for a hard or flash disk drive for the system software, and logging and off-line system files. A cover is preinstalled over the slots.

RJ-45 RS-232 Console port

RJ-45 10-Mbps half-duplex Ethernet management connector

RJ-45 RS-232 Diag connector (reserved for field service diagnostic use only).

Eight auto-sensing 10/100-Mbps Ethernet (10BASE-T/100BASE-TX) interfaces

Optional integrated Secure Sockets Layer (SSL) termination

SFP GBIC (1000BASE-SX or LX) with LC-type connectors. The GBIC can use either:

Longwave-length SFP GBICs (CSS5-GBIC-LX). The longwave length transceiver (1000BASE-LX) can reach 550 meters for all multimode media types. For single-mode fiber, the distance is 5,000 meters.

Shortwave-length SFP GBICs (CSS5-GBIC-SX). The transceiver distance can reach from 220 meters to 500 meters, depending on the quality of the fiber.


Warning Because invisible radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to radiation and do not stare into open apertures.

If you encounter problems with the modules in the CSS 11503 and CSS 11506, see the "Troubleshooting the CSS Modules" section later in this chapter.

CSS 11503 and CSS 11506 Module Overview

The CSS 11503 and CSS 11506 are compact modular platforms, delivering transport and application (layers 4-7) services for Internet and Intranet data centers. A CSS is a fully-distributed architecture with all modules in the system contributing to the overall processing and memory needs for flow set up. Performance increases incrementally as you add modules, and the modules balance the overall traffic load.

The Cisco 11506 is a five-rack unit, supporting six-slots, with 40-Gbps aggregate throughput. The CSS 11506 requires at least one Switch Control Module (SCM) and may be configured with a second SCM in standby mode for redundancy. With the required SCM in one slot, the CSS 11506 has five additional slots supporting any combination of I/O modules.

The Cisco 11503 is a two-rack-unit, supporting three-slots, with 20-Gbps aggregate throughput. The CSS 11503 requires an SCM and accommodates any two of the other modules.

Though all modules except for the SSL module participate in flow setup, they differ primarily in control functions, performance, and I/O. Each CSS 11500 module consists of one high-speed MIPS RISC processor for flow-setup, one network processor for flow forwarding, one policy co-processor for search operations and a maximum of 288 MB of RDRAM (up to 256 MB of usable memory).

The CSS 11506 not only supports redundancy in SCMs but also supports redundant power supplies and redundant Switch Modules (20 Gbps each). A CSS 11506 can contain a maximum of three power supplies, but it requires two functioning power supplies to guarantee service.

The CSS modules are as follows:

288 MB (256 MB of usable memory) Switch Control Module (SCM) with:

Two 1000-Mbps Ethernet (1000BASE-SX or LX) small-form factor pluggable gigabit interface converters (SFP GBICs) with LC-type connectors.

Two PCMCIA slots for a hard or flash disk drive for the system software, and logging and off-line system files.

RJ-45 RS-232 Console port

1 RJ-45 10-Mbps half-duplex Ethernet management connector.

Switch Module (SM). An SM provides connectivity among the SCM and IOMs.

The CSS 11503 has a single integrated SM. A single SM has an aggregate throughput of 20 Gbps.

The CSS 11506 has two removable SMs that share the switching functions. Two SMs provide 40 Gbps aggregate throughput. As implemented in WebNS 5.10 and greater, if one SM fails, the CSS reboots and continues to operate through the other SM.

Two slots in the CSS 11503 and five slots in the CSS 11506 are configurable with:

Fast Ethernet Modules that provide either 8 or 16 auto-sensing 10/100-Mbps Ethernet (10BASE-T/100BASE-TX) RJ-45 ports.

Gigabit Ethernet Modules provides up to two 1000-Mbps Ethernet (1000BASE-SX or LX) SFP GBICs with LC-type connectors.

A Session Accelerator Module (SAM) that provides a cost-effective way to add flow performance when additional connectivity is not required. Using the same flow setup and forwarding processors as the I/O modules, it provides the flexibility to optimize the CSS for port density and performance.

A Secure Socket Layer (SSL) module that functions as an SSL server by adding security services between the Web browsers (the client) and HTTP servers and backend SSL servers. The SSL module is responsible for all user authentication, public/private key generation, certificate management, and packet encryption and decryption functions between the client and the server. Each SSL module terminates SSL connections received from a client. The CSS 11503 supports a maximum of two SSL modules and the CSS 11506 supports a maximum of four SSL modules. For information on SSL commands and functions, refer to the Cisco Content Services Switch Advanced Configuration Guide.

An additional SCM to serve as a passive redundant module.

Switch Control Module Connectors and LEDs

The Switch Control Module (SCM), model CSS5-SCM-2GE, provides master control and is responsible for the following functions:

System powerup and boot control

Centralized routing table management

System-wide connection management

An interface to an external Network Management Station

Disk management

An external RS-232 interface

A CSS supports a maximum of two SCMs, one active and one passive.

The Switch Control Module contains the following connectors and slots:

1 RJ-45 10-Mbps half-duplex Ethernet management connector.

1 RJ-45 RS-232 Console connector.

1 RJ-45 RS-232 Diag connector (reserved for field service diagnostic use only).

2 SFP GBICs (1000BASE-SX or LX) with LC-type connectors.

Two PCMCIA slots for a hard disk or flash disk. A cover is preinstalled over the slots.


Note The SCM can have a maximum of two disk drives.


The SCM front panel LEDs indicate module and configuration status:

Two status module LEDs indicating power and module readiness

Link/Act and Duplex LEDs for the Ethernet management port

Link LEDs for each SFP GBIC


Warning Because invisible radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to radiation and do not stare into open apertures.
