Warning

OPTION-A

OPTION-B

While performing a turbo boot of 4.0.X (PX) images the ROMMON version needs to be 2.01 due to image size increase, otherwise the turbo boot will fail. Refer to Appendix A for more information on performing the turbo boot. Appendix A also describes how to upgrade your ROMMON version to 2.01

Currently on most systems with IOS-XR Softw are Re lease 3.8.4 or hi gher or IOS-X R Softwa re Release

3.9.0 or higher images ROMMON version 1.54 is supported/installed. While upgrading from IOS-XR Software Release 3.8.4 or higher to IOS-XR Software Release 4.0.0.X (PX) you can upgrade the FPD images using the Auto FPD procedure. The Auto FPD procedure upgrades the ROMMON images on ROMMON B before resetting the router for upgrades. After the software upgrade is complete and the router is up and running you then have to manually upgrade the ROMMON A images. Upgrade ROMMON A by executing the following command from admin mode:

RP/0/RP0/CPU0:CRS-1(admin)#upgrade rommon a all disk0

For Auto FPD to work please execute the following command in admin mode

RP/0/RP0/CPU0:CRS-1(admin-config)# fpd auto-upgrade

The other option is to upgrade the ROMMON manually after the image upgrade. The upgrade will not fail even if the ROMMON images are 1.54 or 1.52.

Detailed procedures for ROMMON upgrade is detailed inthe Upgrading and Downgrading ROM

Monitor Firmware on Cisco CRS Routers section in the Cisco IOS XR ROM Monitor Guide for the Cisco CRS Router document online.

Chapter 1 Migrating to a Cisco CRS-3 Carrier Routing System

Cisco IOS-XR Flash Disk Requirements for Migration to CRS-3

You can only upgrade your filesystem to FAT32 u sing the CLI specifed in this section if you are running Cisco

IOS XR software Release 3.8.2 or above.

If you are running a release of Cisco IOS XR software earlier than 3.8.2 please refer to Upgrading Your

File System From FAT16 to FAT32 in Appendix A, “Turbo Boot Procedure” for formatting the File

system to FAT32 using KSH. Cisco IOS XR software Release 4.0.X (PX) requires at least a 2GB flash disk for installation or upgrade.

So prior to upgrading your current IOS XR software to IOS-XR Software Release 4.0.X (PX), you will need to upgrade the flash disk to either 2GB or 4GB.

The size of the image is significantly higher on the Cisco CRS-3 because x86 support is now included in addition to the PPC support. A FAT32 formatted flash disk will decrease the required space for the file system significantly. It is highly recommended to use a 4G flash disk with FAT-32 file-system on the Cisco

CRS-3.

Checking your Existing Flash Disk Size

Execute the show filesystem command to check the actual disk0 size:

RP/0/RP0/CPU0:Router#sho filesystem Wed Feb 11 15:28:57.401 PST PST File Systems:

In the example shown, the flash disk (disk0) size is 1 Gig. If the disk size is smaller than 2Gig you will need to upgrade the flash disk. The procedures for flash disk upgrade are detailed in the Cisco XR 12000 Series Router and Cisco CRS-1

Router Flash Disk Upgrade Tasks document online here:

http://www.cisco.com/en/US/docs/routers/xr12000/xr_line_cards/flashdisk/flashdisk.html

Flash Disk Upgrade Process to 4GB

Inserting the 4GB Flashdisk

The first step is to insert a 4GB Cisco Authorized Flash disk int o slot disk1 of Act ive and Standby RP. After Insertion verify the 4GB disk is accessible from RP

Model: UNIGEN FLASH

Capacity: 8215201 Sectors, Total 4206182912 Bytes, (512 Bytes/sector

Disk Formatting

Format the 4GB flashdisk on standby RP disk1: by executing the following command

RP/0/RP0/CPU0:ios#format disk1: partition filesystem fat32 location 0/rp1/cpu0

The above command will create a partition of 3.5/0.5 between disk1 and disk1a

Note Executing this command will not cause the RP to reset

Verifying the Disk File System

Verify the filesytem is changed to FAT32 file system and desired 80% and 20% partition between disk1 and disk1a disks by executing the following command

Setting Up Disk Mirroring

Mirror the primary disk0 and standby disk1 disks on Standby RP using the command

RP/0/RP0/CPU0: LOAD(config)#mirror location 0/rp1/cpu0 disk0:disk1:

Verify that mirroring is enabled by executing the following command

RP/0/RP0/CPU0:LOAD#show mirror location 0/rp1/cpu0

Swapping Mirrored Disks

After verifying that disk mirroring is successfully enabled i n the previ ous section, swap disk0 w ith disk1 (insert 4GB disk in disk0 slot)

Verifying Standby RP Disk Upgrade

Verify that the Standby RP boots with the 4GB flashdisk as the primary disk(disk0) on the Standby RP.

File System Upgrade Procedure for 2GB Flash Disks

Performing Switchover

Perform an RP switchover and verify that the Standby RP becomes the Active RP.

Upgrading the Standby RP

Once you have verified the switchover was successful, repeat the flashdisk upgrade steps on the new Standby RP and verify results.

File System Upgrade Procedure for 2GB Flash Disks

First do the format of the boot device of the standby RP location.

format disk0: unpartition filesystem fat32 location 0/rp1/CPU0

This command formats the boot device of the stan db y RP an d results i n a reload of t he standby RP. This will result in a 2GB FAT32 file system, Since the device is unpartitioned means no disk mirroring.

Once the standby RP reload, it would come back, format the device with your specifications and would start downloading all the packages from RP again. This takes time depending on the number of packages/config you have on the RP.

Verify using the below command that Standby RP disk is running with your expected filesystem/partition.

show media location 0/rp1/CPU0

Once the standby RP is up and running, perform a Switch Over from the acti v e to the standb y RP and let the new Standby RP (old Active) come up as standby Ready.

Perform the process for the new standby RP location as well.

Reducing Disk Space Usage

If the flash disk size is 2 Gig you still may want to increase available disk space. In order to provide as much room as possible on the disk, one can remove old f iles from the disk. This may include f iles which the operator has placed on the disk device such as PIE files or temporary directories that have been created.

When preparing for the upgrade to the next version of the operating system, the old, non-operational version should be removed.

To remove old SMU files and old versions of the operating system use the admin-commands

install commit

to ensure all active packages are 'committed', then issue the command

install re move in ac tive

The install re move i na ctive te st s yn c command can be used first to show which packages will be removed from the disk.

Note In addition to checking the installation disk device, the bootflash device on the MSCs should also be

checked. Extraneous files such as crashinfo files can be removed.

File System Upgrade Procedure for 2GB Flash Disks

To check the free space of the bootflash use the following command:

dir bootflash: location 0/1/CPU0

Check if all the cards in the system are all up using the admin command

show platform

If any of the cards do not boot properly they have to be replaced or be shut down using the admin command

hw-module power disable location <loc>

Minimizing Traffic Loss During the Upgrade

To minimize traffic loss during the upgrade please follow below steps:

Step 1 Make sure that all the traff ic flowing through the router which needs to be upgraded h as an alternate path .

In this scenario one can take one of the redundant r outers out of service, upg rade it and then bring it back into service without any significant t raffic loss (this sh ould work for the core routers, for the edge de vices usually the redundant path may not be available)

Step 2 Set IGP metric to the highest possible value so the IGP will try to route the traffic through the alternate

path.

Chapter 1 Migrating to a Cisco CRS-3 Carrier Routing System

For OSPF use the max-metric command.

router(config-ospf)#max-metric router-lsa

For ISIS use the spf-overload-bit command.

router(config-isis)#set-overload-bit

Step 3 After all the software is upgraded restore the IGP metric by removing the commands:

For OSPF use the no max-metric command

router(config-ospf)#no max-metric router-lsa

For ISIS use the no spf-overload-bit command.

router(config-isis)#no set-overload-bit

Prior to release 3.8 the above commands have to be run before the install activate command is executed, resulting in a long period of time when the router is taken out of forwarding path.

To minimize this behavior starting from release 3.8, an enhancement has been provided which allows you to pause the install activate command just prior to the router reloading and to execute configuration changes such as IGP commands listed above.

Execute the following command to enable this in stall op tion:

router(config-isis)#install activate disk0:*4.0.* pause sw-change

You will be prompted pri or to the sy stem reload to execute configuration change s such as IGP commands. At this point the IGP cost-out operation can be executed.

Step 4 Copy the running-configuration and admin-configur ation to a temporary sto rage location. This co uld be

on a remote TFTP server or a device such as the hard disk: or disk0: present on the RP.

router#copy running-config tftp://…running_config.txt router#admin router(admin)#copy running-config tftp://…admin-running_config.txt router(admin)#exit

Step 5 Verify Mgmt access to the router (see caveats section) Step 6 While upgrading from 3.x.x images to 4.x.x images upgrade the file system of flash disks (boot device

which is typically disk0) to FAT32 file system for 2 GB and 4 GB flash disks. The procedure to upgrade the file system of flash disks is different for 2GB and 4 GB Flash disks.

Verifying that the System Meets RP Memory Requirements

Due to image size increase on x8 6 bas ed PX i mag es you will need to have at least 1 GB of free memory on each of the Route Processor (RP) modules.

Execute the following command to verify the free memory on the RP.

Execute the cfs check/clear configuration inconsistency command to verify/fix configuration file system in exec and admin mode.

Additional Pre-upgrade System Checks

Due to increasing size of the images sufficient disk space is required to perform the upgrade. the 2Gig flash disk option was first introduced in release 3.7.0, An optional 4Gig flash disk is available starting with the IOS XR 3.8.4 release.

When upgrading to release 4.0.0 or higher, a PCMCIA flash disk of 2Gig or lar ger has to be instal led in the system BEFORE the software upgrade is performed.

In order to provide as much room as possible on the disk, one can remove old files from the disk. This may include files which the operator has placed on the disk device such as PIE files or temporary directories that have been created.

When preparing for the upgrade to the next version of the operating system, any old, non-operational versions should be removed.

Step 2 Remove old SMUs and old versions of the operating system files by executing the following admin

commands:

RP/0/RP0/CPU0:router(admin)# show install inactive

Node 0/0/CPU0 [LC] [SDR: Owner] Boot Device: mem: Inactive Packages: disk0:hfr-fit-px-4.0.0.63I disk0:hfr-infra-test-px-4.0.0.65I disk0:hfr-upgrade-px-4.0.0.65I disk0:hfr-fit-px-4.0.0.65I disk0:hfr-cgn-px-4.0.0.63I disk0:hfr-mpls-px-4.0.0.63I disk0:hfr-mcast-px-4.0.0.63I disk0:hfr-fpd-px-4.0.0.65I disk0:hfr-fpd-px-4.0.0.63I disk0:hfr-diags-px-4.0.0.63I disk0:hfr-diags-px-4.0.0.65I

Execute the install remove inactive test sync command first to show which packages will be removed from the disk.

router(admin)#copy running-config tftp://…admin-running_config.txt router(admin)#exit

Step 5 Verify Mgmt access to the router

Note Cisco recommends copying all the Mandatory PIE files, Optional PIE files, and Recommended

SMUs to the hard disk as part of pre-maintenance acti vity. This will save significant time duri ng the upgrade process.

Upgrading to Cisco IOS XR Software Release 4.0.X(PX) Before Migrating to Cisco

Before migrating your CRS-1 hardware to CRS-3 hardware you must complete the software upgrade to Cisco

IOS XR software Release 4.0.X(PX).

Note All install operations should be done while logged into admin mode.

Step 1 Add the required PIEs to disk:

router(admin)# install add tar <source>/<path>/<pie> sync

The <source> keyword can be one of disk0:, disk1:, compactflash:, harddisk:, tftp:, ftp: or

.

rcp:

The above step must be repeated for each PIE file, or all of the PIEs can be added together in a single install add command. To add all PIEs using a single command, list all of the PIEs (including their source) within the install add command in the following manner:

router(admin)# install add <source>/hfr-mini-px.pie-<version> <source>/hfr-mcast-px.pie-<version> <source>/hfr-mgbl-px.pie-<version> <source>/hfr-mpls-px.pie-<version> <source>/hfr-k9sec-px.pie-<version> <source>/hfr-diags-px.pie-<version> hfr-upgrade-px.pie sync

Note The use of the sync option prevents other users from executing any other command during the

install operation.

CRS-3 Hardware

The <source> keyword can be specified just once rather than for each package. This simplifies the command:

router(admin)# install add <source> hfr-mini-px.pie-<version> hfr-mcast-px.pie-<version> hfr-mgbl-px.pie-<version> hfr-mpls-px.pie-<version> hfr-k9sec-px.pie-<version> hfr-diags-px.pie-<version> hfr-upgrade-px.pie <version> sync

OL-13669-03

Chapter 1 Migrating to a Cisco CRS-3 Carrier Routing System

Upgrading to Cisco IOS XR Software Release 4.0.X(PX) Before Migrating to Cisco CRS-3 Hardware

Note Under idle conditions, the "install add" operation may take up to 65 to 100 minutes. During the

“install add” operation your Cisco CRS Series router will remain fully functional.

Note If you have any other optional packages installed, the current upgrade has to be done with the

optional packages already installed. Otherwise all optional packages have to be deactivated (following by the commit) before the upgrade. Side effect of this is loss of the configuration supported by the PIE.

From Cisco IOS XR software release 3.6.0 onward, an alternate way of adding and installing PIEs is available. If the PIE files are compressed using tar format they can be loaded on the router using the following command:

router(admin)# install add tar <source>/<path>/<tar_file> sync

Step 2 Test the activation using the test option. Testing the activation will give you a preview of the activation.

router(admin)# install activate disk0:hfr-mini-px.pie<version> disk0:hfr-mcast-px.pie<version> disk0:hfr-mgbl-px.pie<version> disk0:hfr-k9sec-px.pie<version> disk0:hfr-mpls-px.pie<version> disk0:hfr-diags-px.pie<version> hfr-upgrade-px.pie sync test

Note No actual changes will be made when you use the test option with the sync command.

Any config that is incompatible with the new version being activated will be identified. The show configuration removed command can be used to view what will be removed as resu lt of the software upgrade (see the Caveats section for details).

Each removed configuration can be reapplied using the load config removed <config>.cfg command from config mode AFTER the upgrade has been completed (see the Caveats section for details).

From Cisco IOS XR software release 3.6 onwards, the install command will accept the use of wildcard pattern matching. The install activate command can be simplified to install activate *3.9* sync test.

FromCisco IOS XR software release 3.7.0 onwards, PIEs can subsequently be activated using the following single command. Th e

<install_operation_id> variable is based on the install operation

ID generated after each install command:

router(admin)# install activate id <install_operation_id> sync test

The install operation ID is printed after finishing each install command or can be obtained by running the show install log command.

Step 3 Activate all of the packages added in step 1:

router(admin)# install activate disk0:hfr-mini-px.pie<version> disk0:hfr-mcast-px.pie<version> disk0:hfr-mgbl-px.pie<version> disk0:hfr-k9sec-px.pie<version> disk0:hfr-mpls-px.pie<version> disk0:hfr-diags-px.pie<version> hfr-upgrade-px.piesync

The output of the install add command executed in step 1 provides the list of names of packages to be used in the install activate operation.

Using the sync option prevents other users from executing any other commands during the install operation.

Chapter 1 Migrating to a Cisco CRS-3 Carrier Routing System

Upgrading to Cisco IOS XR Software Release 4.0.X(PX) Before Migrating to Cisco CRS-3 Hardware

The router will reload at the end of activation to start using the new packages.

Note Under idle conditions, this operation may take at least 20 minutes to complete.

From Cisco IOS XR software release 3.8 onwards, the install command install activate *3.9.* pause sw-change sync can be used to enable the user to cost the router out of th e IGP path just before the rout er

reloads, rather than at the point where the activation commences.

Step 4 Verify system stability through executing the commands described under the Check System Stability

section. This release does not support downgrades from PX to P images.

Step 5 Verify activation is successful. Once activation is done and before the install commit operation,

deactivate and remove the upgrade-px.PIE.

Step 6 After removing the upgrade-px.PIE execute the i nstall commit command to commit the newly activ ated

software

router(admin)# install commit

Step 7 Check to see if there were any failed startup configurations. If there were any startup configurations that

failed (were not applied), then refer to the Caveats section to see how it should be handled.

router# show config failed startup

In same very rare cases inconsistencies in the content of the internal configuration files can occur. In order to avoid such situations, the following steps are recommended before activating packages:

Step 8 Clear the NVGEN cache:

router# run nvgen -F 1

Step 9 Create a dummy config commit:

router# config router(config)#hostname <hostname> router(config)#commit router(config)#end

Step 10 Force commit update by using the reload command. Press n when the confirmation prompt appears:

router# reload Updating Commit Database. Please wait...[OK] Proceed with reload? [confirm] <- Press "n"

In same cases the following error may be reported:

router#reload

Preparing system for backup. This may take a few minutes ............System

configuration backup in progress [Retry later]

In such a case please re-try the command after some time.

Disk Cleanup (Optional)

Once the software upgrade or downgrade has been completed, you can recover some disk space by removing any inactive packages that are no longer needed (if the packages are required at a later time, they can be re-added):

Step 1 Obtain the list of inactive packages and note the names of packages that are not needed:

router(admin)# show install inactive brief

Step 2 Remove the unnecessary inactive packages:

router(admin)# install remove disk0:<package_name1> disk0:<package_name2> .. disk0:<pkg_nameN> sync

http://www.cisco.com/en/US/docs/routers/crs/software/crs_r4.0/general/release/notes/reln_402crs.html

Caveats:

During software upgrade or downg rade, the system could detect incompatible configur ation and remo ve it from the running configuration. The removed configuration will be saved to a file on the router. A configuration could also fail due to syntax or semantic error as the router boots the new version of the software.

To resolve these issues, you must browse the removed or failed configuration and then address the changes so that the configuration can be properly applied on the new version of software.

Addressing Incompatible and Removed Configurations

During the test activation of a new software version, incompatible configurations will be identified and removed from the router running configuration. Syslog and console logs will provide the necessary information on the name of the removed configuration file. To address the incompatible configuration, you should browse the remov ed conf iguration f i le, address the syntax and semantics errors and re-app ly the config as required and/or applicable after upgrade.

To display the removed configuration, execute the following command from exec mode:

router# show configuration removed <removed config filename>

Chapter 1 Migrating to a Cisco CRS-3 Carrier Routing System

Addressing Failed Admin and Non-Admin Configurations During Reload

Some configuration may fail to take effect when the router boots with the new software. These configurations will be sav ed as failed conf iguratio ns. During acti vation o f the new sof tware versio n, you will be notified via syslog and console log if a configuration failed to take effect. To address the failed configuration, you should browse both the admin and non-admin failed configurations, address any syntax and semantics errors found, and then re-apply it as required.

To display the failed configuration, execute the following commands:

router# show configuration failed startup router(admin)# show configuration failed startup

MDR - Minimum Disruption Restart

The MDR (Minimum Disruption Restart) feature is not supported for upgrades to the Cisco

IOS XR software 4.0.0.T, Cisco IOS XR software 4.0.1, or Cisco IOS XR software 4.0.2 releases.

Limitations With the Preconfig Interface

It is important that you check to see whether the persistent config and the running config are the same or different. If they are different then it will ha ve a problem af ter reload/upgrade, because reload/upgrade will use the persistent config to restore configuration and the restored configuration will be different from the one you were running.

Execute the following commands to verify that the persistent conf ig and the runnin g config are the same:

show cfgmgr persistent-config - shows the persistent config in CLI form show running-config - shows running config

You should not use the no interface preconfig <> command if you find that the same config exists in both preconfig and activate. Use the cfs check command to resolve the inconsistency.

Upgrade Instructions for FAT32

Step 1 Once the system is up and running with FAT32, please check the disk usage on the router and make sure

at least 1.3 GB is free on the Cisco shouldn't be taking more than 600 MB)

a. Please make sure all inactive old Cisco IOS XR software rele ase pack ages (older than

Cisco

IOS XR software release 4.0.0.T) are removed from the disk.

b. Please make sure all dumper core files and any user files like PIEs etc. are removed from the boot

device to save space.

Step 2 Make sure system (RP) has available memory. Please refer to the table above with title RP/SP/LC

Memory Requirements during Upgrade.

Step 3 Make sure other management nodes RP/DRP/SC also have available memory. This is applicable to a

multishelf platform. The available memory on other RPs should be around the same as the Standby RP of the DSC.

Step 4 Copy the TAR ball of all Cisco IOS XR software release 4.0 PX packages (mini-px.pie + upgrade

package + optional PX Package and any SMUs) to the hard disk.

Warning

Make sure the T AR pa ckag e contains all the necessary optional packages (mgbl, mpls, mcast, k9sec, doc, diag, fpd). If any of the packages are missed during the upgrade, upgrade activation doesn't complain about the missing package and incompatibilities.

If install add is being done as TAR ball, then the memory requirements on the Route Processor (RP) would be high as contents would be untarred in the /tmp folder. To avoid the usage of RP memory, you can resort to install add of independent packages using the below command. But this typically leads to longer install add times than with the TAR ball install add.

Information About Migrating to a Cisco CRS-3 Carrier Routing System

The difference between migrating a single-chassis Cisco CRS-1 Carrier Routing System to a single-chassis Cisco Carrier Routing System is the fabric upgrade. A single-chassis Cisco uses fabric cards designed for 40 GB operation (FC/S cards), and an LCC in a Cisco Routing System uses fabric cards designed for 140 GB oper ation (FC-140G/S cards). On a single chassis system, each fabric card represents one fabric plane. To migrate a single-chassis Cisco Routing System to a single-chassis Cisco you must do the following:

1. Use CLI commands to prepare the FC/S fabric card for replacement with an FC-140G/S card.

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

3. Replace the FC/S card with an FC-140G/S card.

4. Bring up the FC-140G/S card.

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

Verify That the Correct Version of IOS-XR Software is Installed

The Cisco CRS-3 is only supported on Cisco IOS-XR release 4.0.0.T and higher software. As detailed in the section upgrade to Release 4.0.X(PX) is available for a router running Cisco IOS XR releases 3.8.0 through

3.9.0. All IOS-XR Software releases prior to 3.8.0 (IOS XR releases 3.4.2, 3.5.3, or 3.6.2) must be

OL-13669-03

Chapter 1 Migrating to a Cisco CRS-3 Carrier Routing System

Benchmark the Traffic

Before starting the migration process, take a snapshot of the traffic flow ing through the router and use it as a benchmark to compare against traffic flow during the migration and/or after completing the migration. Since it is a hitless migration, there should be zero impact to the traffic flow during the migration and/or after completing the migration.

• 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-140G/S card and restore service to that fabric plane before upgrading the next fabric plane.

• You will probably want to perform the migration during a network maintenance window or when

system traffic is light.

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

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

• Cisco recommends not moving a chassis after it is cabled. Before the fabric cables are installed, the

chassis should be fully installed with power supplies, console cables, grounded, and so forth

How to Migrate to a Cisco CRS-3 Carrier Routing System (16-Slot)

To migrate from a 16-slot Cisco CRS-1 Carrier Routing System to a 16-slot Cisco CRS-3 Carrier Routing System, you must complete the following tasks:

• Administratively Disabling the Fabric Plane, page 1-5

• Disabling Power to the CRS-1 Fabric Card, page 1-7.

• Physically Removing the CRS-1 Fabric Card, p age 1-9

• Installing an SFC, page 1-11.

• Verifying the Installation of an SFC, page 1-15

The migration procedure may be done on one Fabric Card at-a-time. In a CRS-1 system with redundant fabric (i.e. 8 planes), upgrade to CRS-3 fabric is hitless - zero drop

in traffic as we upgrade plane by plane from a CRS-1 to CRS-3. The detailed migration procedure is detailed in the sections below, for the 16-slot Cisco CRS-1 Carrier

Routing System.

Administratively Disabling the Fabric Plane

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

Before performing this task, you must first open the front (SFC) side cosmetic doors (if installed). You must already have an OIM installed in your chassis in the slot corresponding to where you plan to install the CRS-3 fabric card before you install the CRS-3 fabric card (for example, if you are planning on installing the CRS-3 fabric card in slot 0, you must have an OIM installed in slot 0 on the rear of the chassis), and you must remove any impedance carrier or slot cover from the slot in which you are installing the CRS-3 fabric card. See the “Installing an OIM” section, th e “ R e m ovi n g a S l ot C ove r” section, and the “Removing an Impedance Carrier” section in the Cisco CRS Carrier Routing System 16-Slot Line Card Chassis Installation Guide.

A CRS-3 fabric card can be installed in any of the slots SFC0 to SFC11 (upper card cage) and SFC12 to SFC23 (lower card cage).

Caution Use the slide-assistance arm to slide cards from the card carrier. DO NOT LIFT CARDS BY THE

SLIDE-ASSISTANCE ARM! Rotate cards onto their vertical axes, then lift them from the bottom, using the slide-assistance arm only as an aid for balance.

How to Migrate to a Cisco CRS-3 Carrier Routing System (16-Slot)

Step 3 Remove the CRS-1 fabric card impedance carrier or CRS-1 fabric card you are replacing from the

designated slot, and set it carefully aside. (See the “Removing an Impedance Carrier” section in the Cisco CRS Carrier Routing System 16-Slot Line Card Chassis Installation Guide or the “Removing an SFC” section in the Cisco CRS Carrier Routing System 16-Slot Line Card Chassis Installation Guide.)

Note Remove only one impedance carrier or CRS-1 fabri c card and in stall one CRS-3 f abric card at a

time. Be sure to verify that each CRS- 3 fabric card is fully installed and secured before installi ng another card.

Step 4 Remove the CRS-3 fabric card you are installing from its antistatic packaging. Step 5 Use the screwdriver to unscrew and remo v e the sheetmet al co v e r o v er th e HBMT connec tors on the rea r

of the CRS-3 fabric card, and set it aside.

Step 6 Remove the caps from the HBMT connectors on the back of the card, and set them carefully aside. Step 7 Visually inspect the connector on the card before you insert it into the chassis. Do not attempt to install

a card with a damaged or dirty connector, as this action may damage the backplane connector or OIM.

Note Rails exist on the upper and lo wer l eft edges of the card that align with th e slots in the card cage.

When you install a card in the card cage, make sure that you orient the card correctly and align these rails when sliding the card into the chassis.

Chapter 1 Migrating to a Cisco CRS-3 Carrier Routing System

Step 8 Grasp the slide assistance arm with one hand and place your other hand under the carrier to support and

guide it into the correct slot. DO NOT LIFT CARDS BY THE SLIDE-ASSISTANCE ARM; lift them from the bottom, using the slide-assistance arm only as an aid for balance.

Caution A CRS-3 fabric card weighs about 30 lb (14 kg). You should use two hands when handling a

CRS-3 fabric card.

Step 9 Slide the card halfway into the slot. Avoid touching the card circuitry and any connectors. Step 10 Pivot both card ejector levers so the openi ngs o n the card ejector cams at the top and bottom of the card

pass over the tabs on each side of the card cage slot.

Caution Verify that the openings on the card ejector cams pass over the tabs; otherwise, one or both

ejector levers might bind when you attempt to close the ejector levers, thereby damaging or breaking one or both ejector levers.

Step 11 Continue sliding the card into the card cage slot until the openings on the card ejector cams engage the

tabs on each side of the card cage slot.

Note The CRS-3 fabric card has guide pins that make initial contact with the backplane connector as

you slide the card into its slot. After the guide pins make contact, continue pushing on the card carrier until the card ejector levers begin pivoting forward, toward the handle in the card carrier.

Step 12 T o seat the card in the backplane connector, grasp both card ejector levers and piv ot them inward to wa rd

the handle in the card carrier until they are flush against the front edge of the card carrier.

How to Migrate to a Cisco CRS-3 Carrier Routing System (16-Slot)

Troubleshooting the CRS-3 Fabric Card

If the installed or replaced CRS-3 fabric card fails to operate or power up on installation:

• Make sure that the card is seated firmly in the Cisco CRS Fabric Card Chassis slot. One easy way

to verify physical installation is to see whether the front faceplate of the CRS-3 fabric card is even with the fronts of the other cards installed in the card cage.

• Check whether the ejector levers are latched and that the captive screws are fastened properly . If you

are uncertain, unlatch the levers, loosen the screws, and attempt to reseat the CRS-3 fabric card.

• Examine the Cisco CRS Fabric Card Chassis alarm module to see if there are any active alarm

conditions. (See the section on the alarm module in Cisco CRS Carrier Routing System 16-Slot System Description.)

• Examine the Cisco CRS Fabric Card Chassis power shelves to see whether the chassis, as a whole,

is receiving power.

Use the Status LEDs, located on the CRS-3 fabric card faceplate, to verify the correct installation of the CRS-3 fabric card:

• When the CRS-3 fabric card is properly installed, the Status LED turns green. If this LED is off,

verify that the CRS-3 fabric card is installed correctly.

Chapter 1 Migrating to a Cisco CRS-3 Carrier Routing System

How to Migrate to a Cisco CRS-3 Carrier Routing System (8-Slot)

To migrate from an 8-slot Cisco CRS-1 Carrier Routing System to an 8-slot Cisco CRS-3 Carrier Routing System, you must complete the following tasks:

• Administratively Disabling the Fabric Plane, page 1-5

• Disabling Power to the CRS-1 Fabric Card, page 1-7.

• Physically Removing the CRS-1 Fabric Card, p age 1-9

• Installing a CRS-3 Fabric Card, page 1-11.

• Verifying the Installation of the CRS-3 Fabric Card, page 1-15

The migration procedure may be done on one Fabric Card at-a-time. In a CRS-1 system with redundant fabric (i.e. 8 planes), migrating to the CRS-3 fabric is hitless - zero

drop in traffic as we migrate plane by plane from a CRS-1 to CRS-3 . The detailed migration procedure is detailed in the sections below, for the 8-slot Cisco CRS-3 Carrier

Routing System.

Administratively Disabling the Fabric Plane

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

set it carefully aside. (See the “Removing an Impedance Carrier” section in the Cisco CRS Carrier Routing System 8-Slot Line Card Chassis Installation Guide or the “Removing an SFC” section in the Cisco CRS Carrier Routing System 8-Slot Line Card Chassis Installation Guide.)

Chapter 1 Migrating to a Cisco CRS-3 Carrier Routing System

Note Remove only one impedance carrier or CRS-1 fabri c card and in stall one CRS-3 f abric card at a

time. Be sure to verify that each CRS- 3 fabric card is fully installed and secured before installi ng another card.

Step 4 Remove the CRS-3 fabric card you are installing from its antistatic packaging. Step 5 Use the screwdriver to unscrew and remo v e the sheetmet al co v e r o v er th e HBMT connec tors on the rea r

of the CRS-3 fabric card, and set it aside.

Step 6 Remove the caps from the HBMT connectors on the back of the card, and set them carefully aside. Step 7 Visually inspect the connector on the card before you insert it into the chassis. Do not attempt to install

a card with a damaged or dirty connector, as this action may damage the backplane connector or OIM.

Note Rails exist on the upper and lo wer l eft edges of the card that align with th e slots in the card cage.

When you install a card in the card cage, make sure that you orient the card correctly and align these rails when sliding the card into the chassis.

Step 8 Grasp the slide assistance arm with one hand and place your other hand under the carrier to support and

guide it into the correct slot. DO NOT LIFT CARDS BY THE SLIDE-ASSISTANCE ARM; lift them from the bottom, using the slide-assistance arm only as an aid for balance.

Caution A CRS-3 fabric card weighs about 30 lb (14 kg). Y ou should use tw o hands when handling the

CRS-3 fabric card.

Step 9 Slide the card halfway into the slot. Avoid touching the card circuitry and any connectors. Step 10 Pivot both card ejector levers so the openi ngs o n the card ejector cams at the top and bottom of the card

pass over the tabs on each side of the card cage slot.

Troubleshooting the CRS-3 Fabric Card

If the installed or replaced CRS-3 fabric card fails to operate or power up on installation:

• Make sure that the card is seated firmly in the Cisco CRS Fabric Card Chassis slot. One easy way

to verify physical installation is to see whether the front faceplate of the CRS-3 fabric card is even with the fronts of the other cards installed in the card cage.

• Check whether the ejector levers are latched and that the captive screws are fastened properly . If you

are uncertain, unlatch the levers, loosen the screws, and attempt to reseat the CRS-3 fabric card.

• Examine the Cisco CRS Fabric Card Chassis alarm module to see if there are any active alarm

conditions. (See the section on the alarm module in Cisco CRS Carrier Routing System 8-Slot Line Card Chassis System Description.)

• Examine the Cisco CRS Fabric Card Chassis power shelves to see whether the chassis, as a whole,

is receiving power.

Use the Status LEDs, located on the CRS-3 fabric card faceplate, to verify the correct installation of the CRS-3 fabric card:

• When the CRS-3 fabric card is properly installed, the Status LED turns green. If this LED is off,

verify that the CRS-3 fabric card is installed correctly.

• If there is a failure during the board boot sequence, the two four-digit alphanumeric LED displays

indicate the current boot phase to assist you in debugging the board failure.

How to Migrate to a Cisco CRS-3 Carrier Routing System (8-Slot)

Each plane transitions from UP -> MCAST_DOWN -> DOWN -> MCAST_DOWN -> UP. Thus each plane will cycle through up->dn twice. This is why the up->dn counter shows 2. Similarly each plane will cycle through mcast_dn->up twice as well and the mcast_dn->up counter shows 2.

Verifying Traffic Statistics on the Newly Migrated Cisco CRS-3 Node

To ascertain that traffic is flowing on the CRS-3 node please run the following command on both the planes that have been migrated. Run it a few times to ensure that the counters are incrementing. The lost or error counters should not be incrementing.

The same command should also be applied on the legacy nodes (not yet migrated) to make sure there is no traffic lost or traffi c with errored cells.

How to Migrate to a Cisco CRS-3 Carrier Routing System (4-Slot)

To migrate from a 4-slot Cisco CRS-1 Carrier Routing System to a 4-slot Cisco CRS-3 Carrier Routing System, you must complete the following tasks:

• Administratively Disabling the Fabric Plane, page 1-5

• Disabling Power to the CRS-1 Fabric Card, page 1-7.

• Physically Removing the CRS-1 Fabric Card, p age 1-9

• Installing a CRS-3 Fabric Card, page 1-11.

• Verifying the Installation of a CRS-3 Fabric Card, page 1-15

The migration procedure may be done on one Fabric Card at-a-time. In a CRS-1 system with redundant fabric (i.e. 8 planes), migration to CRS-3 fabric is hitless - zero drop

in traffic as we migrate plane by plane from a CRS-1 to CRS-3 . The detailed migration procedure is detailed in the sections below, for the 4-slot Cisco CRS-3 Carrier

Routing System.

Places the router in administration EXEC mode.

• All commands listed in this procedure should be

entered on the pre-existing single-chassis system.

Places the router in administration configuration mode.

Shuts down the fabric plane in the system.

• In a 4-slot CRS-1 router, we have four fabric nodes, or

Fabric Controller cards, numbered 0/SM0/SP to 0/SM3/SP. Each Fabric Controller card has one plane. So for a 4-slot CRS-1 to CRS-3 migration we will be migrating one plane at a time for all four planes.

Commits the target configuration to the router running configuration.

• This step brings up the previously shutdown plane,

which is now configured to use the CRS-3 fabric card.

Changes the mode from administration configuration mode to administration EXEC mode.

Example:

RP/0/RP1/CPU0:router(admin-config)# end

Step 6 Step 7

Repeat Step 3 through Step 5 for each fabric plane.

What to Do Next

Next we disable power to the Fabric node, and verify that node is moved to Unpowered state.

Disabling Power to the CRS-1 Fabric Card

Prerequisites

Software Requirements

• Cisco IOS XR Software Release 4.0.0.T or later release (Cisco IOS XR Software Release 4.0.2 for

multishelf nodes)

• ROMMON 1.54 or later version (for Route Processor [RP])

Displays the administrative and operational status of all eight fabric planes.

• Verify that all fabric planes are administrative state

down.

Chapter 1 Migrating to a Cisco CRS-3 Carrier Routing System

• ROMMON 1.52 or later version (for Dual Route Processor [DRP])

Caution The ROM Monitor software must be upgraded to version 1.54 or a later version on all RPs and/or

upgraded to version 1.52 or a later version on all DRPs before a Cisco Cisco

IOS XR Software Release 4.0.0.T or later release. If the router is brought up with an incompatible version of the ROM Monitor soft ware, then the standby RP may fail to boot. For instructions to ov ercome a boot block in the standby RP in a single chassis system, see Cisco other issues, contact your Cisco Systems support representative for assistance. See Obtaining

Documentation, Obtaining Support, and Security Guidelines, page

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