Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and
S4 service requests are those in which your network is minimally impaired or for which you require
product information.) After you describe your situation, the TAC Service Request Tool provides
recommended solutions. If your issue is not resolved using the recommended resources, your service
request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:

http://www.cisco.com/techsupport/servicerequest

For S1 or S2 service requests, or if you do not have Internet access, contact the Cisco TAC by telephone.
(S1 or S2 service requests are those in which your production network is down or severely degraded.)
Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business
operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: [phone]
Australia: 1 800 805 227
EMEA: [phone]
USA: 1 800 553 2447

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity
definitions.

Severity 1 (S1)—An existing network is “down” or there is a critical impact to your business operations.
You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your
business operations are negatively affected by inadequate performance of Cisco products. You and
Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of the network is impaired while most business operations
remain functional. You and Cisco will commit resources during normal business hours to restore service
to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or
configuration. There is little or no effect on your business operations.

Documentation” section on page 1-17.

Note You cannot connect the fabric cables to the pre-existing single-chassis rack until you replace the FC/S

cards in the line card chassis (LCC). To avoid service interruption, replace these modules and connect
the fabric cables only when instructed to do so in the procedure that appears in the “How to Upgrade to

a Multishelf System” section on page 1-3.

• Prepare the additional LCC as follows:

–

Install the LCC and all cards.

–

Obtain the chassis serial number, which is required for configuration.

–

Ensure that the power to the LCC is off.

OL-12571-01

Chapter 1 Upgrading to a Multishelf System

Information About Upgrading to a Multishelf System

Information About Upgrading to a Multishelf System

The difference between upgrading a single-chassis system to a multishelf system and installing a
multishelf system is the fabric upgrade. A single-chassis system uses fabric cards designed for
single-chassis systems (FC/S cards), and an LCC in a multishelf system uses fabric cards designed for a
multishelf system (FC/M cards). On a single chassis system, each fabric card represents one fabric plane.
To upgrade a single-chassis system to a multishelf system without interrupting service, you must do the
following:

1. Use CLI commands to prepare each FC/S fabric card for replacement with an FC/M card.

2. Shut down the plane on each FC/S card before it is replaced.

3. Replace the FC/S card with an FC/M card.

4. Bring up the FC/M card.

5. Repeat Step 2 through Step 4 until all planes (0 through 7) are upgraded.

When you plan to perform a single-shelf to multishelf system upgrade, consider the following:

• You need these components:

–

Fabric card chassis and new line card chassis.

–

Cisco Catalyst 6509 Switch, which provides the control Ethernet network for the multishelf
system control traffic. We highly recommend two switches for redundancy.

–

S13 cards for the original line card chassis (to replace the original S123 cards in the chassis).

–

Optical array cables (48 cables for each multishelf system and 24 cables for each line card
chassis).

–

Additional MSCs and PLIMs for the new line card chassis.

• To avoid traffic loss, you must upgrade the switch fabric one plane at a time. To do that, you must

replace each FC/S card with a new FC/M card and restore service to that fabric plane before
upgrading the next fabric plane.

• You might want to perform the upgrade during a network maintenance window or when system

traffic is light.

Note Be sure to review the upgrade procedures before deciding when to schedule the upgrade.

That way, you can familiarize yourself with the upgrade procedure and determine if there
are other issues to consider before performing the upgrade.

• Are there cabling issues to consider when you add the new chassis to the existing chassis?

For example, will you have to install optical chassis interconnect cables between the chassis before
you bolt the chassis to the floor? If so, be sure to protect the cables while moving the chassis.

How to Upgrade to a Multishelf System

To upgrade a single-chassis system to a multishelf system, you must complete the following tasks:

• Upgrading the Fabric Cards and Adding an FCC, page 1-4

• Adding an LCC to a Multishelf System, page 1-9

Cisco CRS-1 Carrier Routing System Multishelf System Upgrade and Conversion Guide

OL-12571-01

How to Upgrade to a Multishelf System

Upgrading the Fabric Cards and Adding an FCC

This section describes how to upgrade the fabric cards in a single-chassis system and establish
communications between the designated shelf controller (DSC) LCC and one or more FCCs.

Prerequisites

Software Requirements

• Cisco IOS XR Software Release 3.4.0 or later

• ROMMON 1.42 or later

Caution The ROM Monitor software must be upgraded to version 1.42 or higher on all RPs before a Cisco CRS-1

system is upgraded to Cisco IOS XR Software Release 3.4.0 or higher release. If the router is brought
up with an incompatible version of the ROM Monitor software, then the standby RP may fail to boot.
For instructions to overcome a boot block in the standby RP in a single chassis system, see Cisco IOS XR
ROM Monitor Guide. If a boot block occurs in a multishelf system, contact your Cisco Systems support
representative for assistance. See Obtaining Technical Assistance, page viii.

Chapter 1 Upgrading to a Multishelf System

Restrictions

SUMMARY STEPS

In addition, Cisco CRS-1 Multishelf systems should be upgraded to ROMMON release 1.42 before being
upgraded to IOS XR Release 3.4.0 to ensure RPs are assigned the correct rack numbers during system
boot.

For more information, see Cisco IOS XR ROM Monitor Guide.

Hardware Requirements

• The system hardware should be prepared as described in the “Prerequisites for Upgrading to a

Multishelf System” section on page 1-1.

• The control network must be set up as described in the “Prerequisites for Upgrading to a Multishelf

System” section on page 1-1.

• The power should be off for the FCCs and any additional LCCs.
