The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. Learn more about how Cisco is using Inclusive Language.
This chapter describes the command-line interface (CLI) techniques and commands used to manage and configure the hardware components of a router running the Cisco IOS XR software.

This module contains the following topics:
You must be in a user group associated with a task group that includes the proper task IDs. The command reference guides include the task IDs required for each command. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
This section describes how to display different types of hardware status information.
To display hardware version information for the components assigned to a secure domain router (SDR), connect to the designated shelf controller (DSC) and enter the show diag command in EXEC mode. The displayed information includes the card serial number and the ROMMON software version.
The syntax for the show diag command in EXEC mode is:
show diag [node-id | details | summary]
In the following example, the show diag command displays information for all nodes in the SDR:

To display hardware version information for all or some of the components assigned in a system, connect to the designated shelf controller (DSC) and enter the show diag command in administration EXEC mode. When this command is entered in administration EXEC mode, you can display information on RSPs, line cards, and system components such as the chassis, fan trays, and power supplies.
 Note |
If you enter the show diag command in EXEC mode, the software displays only the hardware assigned to the SDR to which you are connected. |
The syntax for the show diag command in administration EXEC mode is:
show diag [node-id | chassis | details | fans | memory | power-supply | summary]
 Tip |
For information on the software version, use the show version command. |
In the following example, the show diag command displays information for all nodes in the system:

This section describes RSP redundancy and switchover commands and issues.
Your router has two slots for RSPs: RSP0 and RSP1 (see Redundant Set of RSPs Installed in Slots RSP0 and RSP1 in an 8-Slot Chassis). RSP0 is the slot on the left, facing the front of the chassis, and RSP1 is the slot on right. These slots are configured for redundancy by default, and the redundancy cannot be eliminated. To establish RSP redundancy, install RSPs into both slots.
During system startup, one RSP in each redundant pair becomes the active RSP. You can tell which RSP is the active RSP in the following ways:
The slot of the active RSP is indicated in the CLI prompt. For example:
RP/0/RSP1/CPU0:router#
In this example, the prompt indicates that you are communicating with the active RSP in slot RSP1. See Cisco ASR 9000 Series Aggregation Services Router Getting Started Guide for a complete description of the CLI prompt.
Enter the show redundancy command in EXEC mode to display a summary of the active and standby RSP status. For example:
RP/0/RSP0/CPU0:router(admin)# show redundancy
Mon Jun 29 04:49:26.098 PST
Redundancy information for node 0/RSP0/CPU0:

A9K-RSP-4G reloaded Thu Jun 11 15:20:50 2009: 2 weeks, 3 days, 13 hours, 28 minutes ago
Active node booted Thu Jun 11 15:20:50 2009: 2 weeks, 3 days, 13 hours, 28 minutes ago
Active node reload "Cause: Turboboot completed successfully"The second RSP to boot in a redundant pair automatically becomes the standby RSP. While the active RSP manages the system and communicates with the user interface, the standby RSP maintains a complete backup of the software and configurations for all cards in the system. If the active RSP fails or goes off line for any reason, the standby RSP immediately takes control of the system.
RSP redundancy is enabled by default in the Cisco IOS XR software, but you can use the commands described in Table 1 to display the redundancy status of the cards or force a manual switchover.
|
Command |
Description |
|---|---|
|
show redundancy |
Displays the redundancy status of the RSPs. This command also displays the boot and switch-over history for the RSPs. |
|
redundancy switchover |
Forces a manual switchover to the standby RSP. This command works only if the standby RSP is installed and in the “ready” state. |
|
show platform |
Displays the status for node, including the redundancy status of the RSP cards. In EXEC mode, this command displays status for the nodes assigned to the SDR. In administration EXEC mode, this command displays status for all nodes in the system. |
Automatic switchover from the active RSP to the standby RSP occurs only if the active RSP encounters a serious system error, such as the loss of a mandatory process or a hardware failure. When an automatic switchover occurs, the RSPs respond as follows:
The reload command causes the active RSP to reload the Cisco IOS XR software. When an RSP reload occurs, the RSPs respond as follows:
 Caution |
You should not use the reload command to force an RSP switchover because the result could be a significant loss of router operations. Instead, use the redundancy switchover command to fail over to the standby RSP, then use the hw-module location node-id reload command to reload the new standby RSP. |
You can force a manual switchover from the active RSP to the standby RSP using the redundancy switchover command.
If a standby RSP is installed and ready for switchover, the standby RSP becomes the active RSP. The original active RSP becomes the standby RSP. In the following example, partial output for a successful redundancy switchover operation is shown:
RP/0/RSP0/CPU0:router# show redundancy
This node (0/RSP0/CPU0) is in ACTIVE role
Partner node (0/RSP1/CPU0) is in STANDBY role
Standby node in 0/RSP1/CPU0 is ready
RP/0/RSP0/CPU0:router# redundancy switchover

Proceed with switchover 0/RSP0/CPU0 -> 0/RSP1/CPU0? [confirm]
Initiating switch-over.
RP/0/RSP0/CPU0:router#

In the preceding example, the Telnet connection is lost when the previously active RP resets. To continue management of the router, you must connect to the newly activated RP as shown in the following example:

RSP Slot Location in Syslog |
Release 7.8.1 |
When an RSP switchover occurs, the router logs the active RSP slot location in the syslog message. This helps you quickly identify the active RSP slot from your router's system log messages. In earlier releases, the RSP switchover syslog message didn't include the active RSP slot location. |
In the event of an RSP switchover, the router logs the following syslog messages:
RP/0/1/CPU0:Feb 19 09:08:00.655 UTC: rmf_svr[436]: %HA-REDCON-6-GO_ACTIVE : this card going active
RP/1/1/CPU0:Mar 8 11:43:29.041 UTC: rmf_svr[147]: %HA-REDCON-6-GO_STANDBY : this card going standby, location RP/1/1/CPU0From Cisco IOS XR Release 7.8.1 onwards, the RSP switchover syslog message for the active RSP includes the RSP slot location as well:
RP/0/1/CPU0:Mar 8 11:42:50.876 UTC: rmf_svr[165]: %HA-REDCON-6-GO_ACTIVE : this card going active , location RP/0/1/CPU0:The active RSP automatically synchronizes all system software, settings, and configurations with the standby RSP.
If you connect to the standby RSP through the console port, you can view the status messages for the standby RSP. The standby RSP does not display a CLI prompt, so you cannot manage the standby card while it is in standby mode.
If you connect to the standby RSP through the management Ethernet port, the prompt that appears is for the active RSP, and you can manage the router the same as if you had connected through the management Ethernet port on the active RSP.

Use the commands described in this section to reload the Cisco IOS XR software on the active RSP or on any specified node in the system. This section also describes the commands used to administratively shut down a node and power a node on or off.
|
Command |
Description |
||
|---|---|---|---|
|
hw-module location node-id power disable |
This command administratively turns the power off for a node. It is entered in administration configuration mode. The changes do not take effect until you enter the commit command. To power on a node, use the no form of this command.
|
||
|
hw-module location node-id reload |
This command works in EXEC mode and reloads the Cisco IOS XR software on a specific node or all nodes. To specify all nodes, enter the all keyword in place of the node-id argument. The node reloads with the current running configuration and active software set for that node. |
||
|
hw-module unshut location node-id |
This command must be entered in the configuration mode. This command is used to administratively bring up the specified node. |
Note |
When you use the hw-module shutdown location node-id command to a line card, you must wait until the configuration is applied before removing the line card. Removal of the line card before the shutdown may result in a hardware issue. |
The reload command causes the active RSP to reload the Cisco IOS XR software according to the configuration register setting. This setting determines how the active RSP acts when reloaded.
This section contains instructions to reload the Cisco IOS XR software and return to EXEC mode. For instructions to use the reload command for entering ROM Monitor bootstrap mode, see ROM Monitor Configuration Guide for Cisco ASR 9000 Routers.
Caution |
Because the reload command causes the active RSP to go off line and either reload the Cisco IOS XR software or enter ROM Monitor mode, the router experiences a loss of service unless a redundant standby RSP is installed and in “ready” state. To display the status of the standby RSP, use the show redundancy command in EXEC mode. |
| Command or Action | Purpose | |||
|---|---|---|---|---|
|
Step 1 |
show redundancy Example: |
Displays the RSP redundancy status.
|
||
|
Step 2 |
admin Example: |
Enters administration EXEC mode. |
||
|
Step 3 |
show variables boot Example: |
Displays the configuration register setting.
|
||
|
Step 4 |
(Optional) config-register register-value Example: |
(Optional)
Sets the configuration register to the respective value. This step is necessary only if the register is not set to the respective value (0x102 or 0x2102) in the running configuration. You can use either 0x102 or 0x2102. Both these values specify the same functionality, as bit 13 in 0x2102 is not significant for Cisco IOS XR software. |
||
|
Step 5 |
admin Example: |
Enters administration EXEC mode. |
||
|
Step 6 |
reload Example: |
Reloads the active RSP according to the configuration register setting.
|
When an RSP is power cycled or experiences an ungraceful reset, the boot disk (PCMCIA flash disk used to boot the card) may experience a file-system corruption. If this occurs, an error message is displayed and the RSP fails to boot. The corrupted flash disk is automatically reformatted and the Cisco IOS XR software is restored from the designated system controller (DSC) for the system.
For example, if a flash disk for an RSP is corrupted, the RP fails to boot and the following error message is displayed:

If this occurs, then the flash disk is automatically reformatted and the Cisco IOS XR software is restored to the flash disk.
Note |
If the flash disk is badly damaged and cannot be reformatted, the disk must be replaced. If the corrupted flash disk is the DSC, then the router fails over to the standby DSC. If no standby DSC is installed, then the system fails to boot. |
The controller , controllers , and show controllers commands are used to manage and display settings for various hardware components, including the switch fabric management, Ethernet control plane, and interface manager. These commands are primarily diagnostic and related to driver-level details. The information available with these commands varies widely and is hardware specific.
For information on the use of these commands, see Interface and Hardware Component Command Reference for Cisco ASR 9000 Series Routers.
To format a storage device on the router, use the format command in EXEC mode.
Caution |
Formatting a storage device deletes all data on that device. |
The following command syntax is used:
format filesystem: [options]
Table 1 describes the format command syntax.
|
Variable |
Description |
|---|---|
|
filesystem |
Specifies the memory device to format. The supported file systems are:
Enter format ? to see the devices supported on your router. |
|
options |
Enter format filesystem: ? to see the available options. For more information, see System Management Command Reference for Cisco ASR 9000 Series Routers. |
In the following example, the format command is used to format the hard disk:
RP/0/RSP0/CPU0:router# format harddisk:
This section describes card replacement issues and procedures.
Line cards are designed for online insertion and removal (OIR). A line card is a single card that contains all service processing functions and physical line interfaces.
The OIR feature allows you to remove and replace cards without removing power to the card or chassis. Removing a card interrupts all traffic passing through the card, but it does not remove the card configuration.
When you remove a card, the configuration remains for all interfaces, but the interfaces do not appear in the output of the show interfaces command. You can view interface configurations by entering the show running-config command. The following example shows how the configuration appears when a card is removed:
RP/0/RSP0/CPU0:router# show running-config
Building configuration...
hostname router
router ospf 3269
area 0
interface POS0/3/0/0
cost 20
!
interface preconfigure POS0/3/0/0
ipv4 address 10.10.50.1 255.255.255.0
!
interface preconfigure POS0/3/0/1
description POS0/3/0/1
shutdown
!
interface preconfigure POS0/3/0/2
description POS0/3/0/2
shutdown
!
interface preconfigure POS0/3/0/3
description POS0/3/0/3
shutdown
!
In this example, the line card in slot 3 is removed, and the interface configuration for all four interfaces changes to “interface preconfigure.” However, the “router ospf” reference to a slot 3 interface does not change. If you replace a line card with another line card that uses the same media type and port count, the configuration becomes active on the replacement card.
To remove the configuration for a slot after a card is removed, use the no interface preconfigure command to remove all interface configuration statements for that card in the running configuration. In addition, search the configuration for any references to the removed interfaces, such as the “router ospf” reference to slot 3 in the preceding example.
To remove the configuration for a slot when a card is installed, use the no interface command to remove all interface configuration statements for that card in the running configuration. In addition, search the configuration for any references to the removed interfaces.
Each line card supports a specific media type (Packet over SONET/SDH [POS] or Ethernet, for example) and port count. If you replace a line card with one that supports a different media type or port count, you should review the configuration and revise it to support the replacement line card.
When you replace a line card or PLIM with a card that is of the same media type and has the same port count as the replaced card, the guidelines in the Removing Line Cards apply. Because the replacement card is of the same media type and port count, no special procedures are required for card removal and replacement.
When you replace a line card with a card that is of the same media type with a different port count, the guidelines in Removing Line Cards apply.
If the new card has a greater port count than the replaced card, the configuration applies to the corresponding lower port numbers, and the ports that did not exist on the replaced card have no configuration and come up in the shutdown state.
If the new card supports fewer ports, the existing configuration for the corresponding number of ports on the new card set is applied. The previous configuration for the removed ports remains in interface preconfigure state, as shown in the following example:
RP/0/RSP0/CPU0:router# show running-config
Building configuration...
hostname rtp-gsr1
interface POS0/3/0/0
ipv4 address 10.10.50.1 255.255.255.0
!
interface preconfigure POS0/3/0/1
description POS0/3/0/1
shutdown
!
interface preconfigure POS0/3/0/2
description POS0/3/0/2
shutdown
!
interface preconfigure POS0/3/0/3
description POS0/3/0/3
shutdown
!
In the preceding example, a four-port card has been replaced with a single-port card. The configuration from port 1 on the four-port card is applied to the single port on the replacement card, and the remaining port configurations change to “interface preconfigure.” To remove the configuration for the missing interfaces, use the no interface preconfigure command. In addition, search for and remove any configuration references to the removed interfaces.
Whenever you replace a line card with the same media type and a different port count, review the running configuration in the router and revise the configuration as necessary.
When you replace a line card or PLIM with a card that is of a different media type (for example, if you replace a POS PLIM with an Ethernet PLIM), the guidelines in Removing Line Cards apply. Review the running configuration in the router and revise the configuration as necessary for the new media type.
The proactive line card shutdown feature enables powering down line cards automatically when the power that is drawn by the router exceeds configured threshold. The sequence of powering down LCs is based on the shutdown priorities that are assigned to them. The LC, however, does not boot automatically even after the router power draw is back to normal below the shutdown threshold. Therefore, you must manually bring up the LC by either reloading or OIR method.
Instead of provisioning more power to the router in worst case power draw scenarios, this feature helps in saving power by powering down the LC.
As part of this feature, you must configure two threshold values:
Syslog Threshold—This value serves as a syslog warning threshold. If the router power draw exceeds the syslog threshold, then a warning error message is captured at the console. This warning message facilitates the user to take any preventive action.
Shutdown Threshold—This value triggers the shutdown of line cards. If the router power draw exceeds the shutdown threshold, then the line cards are shutdown based on the priorities that are assigned to them. The system monitors the power draw for every 10 seconds.
You can configure a shutdown priority value of 0 to 19. A line card with lower value has the highest priority. By default, a priority of 20 is assigned to all the LC in the router.
When two or more LCs have equal priorities that are assigned, then the slot number takes precedence in the priority calculation. A lower slot number has the highest priority. For instance, when two LCs at slot 0 and slot 19 have the priority set as 10, then LC in slot 0 has higher priority than the LC in slot 19.
Consider the following points while configuring proactive line card shut down feature:
Shutdown threshold must be greater than the current system power draw.
Shutdown threshold must be greater than the syslog threshold.
Shutdown threshold must not be less than 3500 Watts.
In Cisco IOS XR 32-bit OS, the priority of a LC is checked only when the LC is in IOS XR RUN state.
In Cisco IOS XR 64-bit OS, the priority of a LC is checked only when the LC is in Operational state.

Advanced power management feature enables powering down the unused line card slices.
This feature helps to manage power consumption, as the slices that do not have any services enabled are power down. Later these slices can be powered when a new service is enabled on them.
This feature is supported on the Cisco ASR 9000 4th Generation Ethernet line cards.
This procedure shows how to configure advance power management.
In this example these slices are powered down:
slice 0, and 7 of the line card in the node 0 location
slice 3, and 6 of the line card in the node 1 location
You should reload the line card for the configuration changes to take effect.

Below two methods are used to delete the data from a RSP and line card. These methods are used based on your requirements:
Erase Disk Memory
Wipe Out Disk Memory
The Erase Disk Memory operation clears the disk memory of RSPs and line cards. However, the deleted data is recoverable using recovery tools. The erase disk memory operation can be performed for quick sanitization of the card before reusing it in another device within the control space of your network or organization.
Erasing disk memory operation uses zapdisk feature to erase the disk memory from the RSP and line card.
Erasing disk memory is done in three steps. First, you enable the zapdisk feature, later identify the card where zapdisk is supported. Next, activate the zapdisk operation on the card:
Enable zapdisk feature on the router.
Example:
sysadmin-vm# zapdisk setFind out the card location where the zapdisk feature is supported using the show zapdisk locations command.
Example:
Router# show zapdisk locations
0/RSP1 Fully qualified location specification
0/7 Fully qualified location specification
0/4 Fully qualified location specification
all all locations
Start the zapdisk operation on a specific node location or all node locations to erase disk memory.
Note |
You can run the zapdisk operation on all RSPs and line cards except the active RSP where zapdisk service is running in an active role. |
After the zapdisk process is completed, the system clears all data and shuts down the card.
This example runs the zapdisk operation on the node location 0/4:
Router# zapdisk start location 0/4
Action on designated location is in progress, more detail logs will be located in sysadmin at
/misc/disk1/tftpboot/zapdisk.log once action is completedNote |
After deleting the data, remove the card from the slot, and do not reload the card or the router. If you reload the card or the router without removing the card, the data is reloaded into the card. |
In the event when you must return or trash a card, the data in the disk memory should be permanently deleted. Therefore, the erase disk memory feature is not advice. You should use the enhanced version of the erase disk memory feature called Wipe Out Disk Memory.
The Wipe Out Disk Memory feature deletes data permanently from the disk memory of RSPs and line cards. The erased data is non-recoverable. We recommmend this action when you perform a return material authorization (RMA) of a card to prevent pilferage of sensitive data.
Wiping out disk memory actions are performed in the ROMMON mode. Generally to boot into ROMMON mode, the config-register boot-mode rom-monitor command is executed from the admin mode. However, the command is not available in Cisco IOS XR 64 bit OS. Therefore you must follow the below sequence to boot into ROMMON mode:
Reload the router
Break into the BIOS menu and select ROMMON
Wipe out disk memory in ROMMON
Before reloading the router, ensure that the redundant RP is disabled in dual-RP routers and console is connected:
sysadmin-vm:0_RSP0# hw-module location all reload
While the router boots, press CTRL+C to break into BIOS menu.
To enter into ROMMON mode, select the Boot to ROMMON option from the available boot options:
Please select the operating system and the boot device:
1) Boot to ROMMON
2) IOS-XR 64 bit Boot previously installed image
3) IOS-XR 64 bit Mgmt Network boot using DHCP server

Use this procedure to upgrade the CPU controller bits on all nodes that are installed in the router or on a specific node.
| Command or Action | Purpose | |
|---|---|---|
|
Step 1 |
admin Example: |
Enters administration EXEC mode. |
|
Step 2 |
upgrade cpuctrlbits {all | location node-id} Example: |
Upgrades the CPU controller bits on all nodes in the router. Use the location node-id keyword and argument to upgrade the CPU controller bits on a specific node. |
The following example shows how to upgrade the CPU controller bits on all nodes in a router:
RP/0/RSP0/CPU0:router# admin
RP/0/RSP0/CPU0:router(admin)# upgrade cpucrtlbits all
Please do not power cycle, reload the router or reset any nodes until all upgrades are completed.
Please check the syslog to make sure that all nodes are upgraded successfully.
If you need to perform multiple upgrades, please wait for current upgrade to be completed
before proceeding to another upgrade. Failure to do so may render the cards under upgrade
to be unusable.

The number of ports on which you can enable 1GbE port mode has been increased from the previous releases. The details of the number of ports on which you can configure 1GbE port mode on the Cisco ASR 9000 Series routers, port expansion card, and line cards is as follows:
Use the hw-module location breakout and hw-module location slice config mode commands to enable 1GbE port mode configuration. |
You can configure the SFP+ ports on the Cisco A9903-8HG-PEC (0.8T PEC card) in 10GbE, 25GbE, or 1GbE mode. By default, all ports are in 10GbE mode.
For more information on the ports, see the Installing Modules and Cables in the Chassis chapter in the Cisco ASR 9000 Series Fixed-Port Routers Hardware Installation Guide.
To configure a port, use the hw-module location slice config mode command.
The port mode configuration is per slice and not per port. Also, the 48 ports on Cisco A9903-8HG-PEC are available in slices 4 and 5. Each slice can be configured for 10GbE, 25GbE, or 1GbE port mode.
The number of ports available on the card depends on the port mode configured on each slice. This table shows the port mode, and available ports on Cisco A9903-8HG-PEC:
|
Port Mode |
Number of Ports |
Available Port Numbers |
|---|---|---|
|
1GbE |
48 24 on each slice |
On slice 4: port numbers 0–23 On slice 5: port numbers 24–47 |
|
10GbE |
48 24 on each slice |
On slice 4: port numbers 0–23 On slice 5: port numbers 24–47 |
|
25GbE |
32 16 on each slice |
On slice 4: port numbers 0–15 On slice 5: port numbers 32–47 |
This sample configuration shows how to configure all ports on Cisco A9903-8HG-PEC in 25GbE mode:
RP/0/RP0/CPU0:ios#configure
RP/0/RP0/CPU0:ios(config)#hw-module location 0/0/CPU0 slice 4 config-mode 4x25GE,4x25GE,4x25GE,4x25GE
RP/0/RP0/CPU0:ios(config)#hw-module location 0/0/CPU0 slice 5 config-mode 4x25GE,4x25GE,4x25GE,4x25GE
RP/0/RP0/CPU0:ios(config)#commit
RP/0/RP0/CPU0:ios#configure
RP/0/RP0/CPU0:ios(config)#hw-module location 0/0/CPU0 slice 4 config-mode 10x1GE,10x1GE,4x10GE,UNUSED
RP/0/RP0/CPU0:ios(config)#hw-module location 0/0/CPU0 slice 5 config-mode 10x1GE,10x1GE,4x10GE,UNUSED
RP/0/RP0/CPU0:ios(config)#commit
By default, all ports are in 10GbE mode. To revert to the default mode, use no form of the hw-module location <node> slice <number> config-mode command. This sample shows how to revert slice 4 ports to the default 10GbE mode:
RP/0/RP0/CPU0:ios#configure
RP/0/RP0/CPU0:ios(config)#no hw-module location 0/0/CPU0 slice 4 config-mode 4x25GE,4x25GE,4x25GE,4x25GE
RP/0/RP0/CPU0:ios(config)#commit
Use the show interface brief command to verify the ports in slice 4 and 5 configured in 25GbE mode:

The router has 48 ports with maximum of 800G data bandwidth capacity. You can configure the 48 ports in various port modes (100GbE, 25GbE, 10GbE, 40GbE and 1GbE) using the hw-module location <node> slice <number> config-mode command.
The port mode configuration is per slice and not per port. Also, the 48 ports on the Cisco ASR 9902 router are available in slice 0 and 1. Each slice can be configured for a mix of 1GbE, 10GbE, 25GbE, 40GbE or 100GbE port modes. The default configuration is 1x100GE, 1x100GE, 10x10GE, and 10x10GE.
For more information on the ports, see the Installing Modules and Cables in the Chassis chapter in the Cisco ASR 9000 Series Fixed-Port Routers Hardware Installation Guide.
The number of ports available on the router depends on the port mode configured on each slice. This table shows the configuration options and supported port modes on Cisco ASR 9902 router:
| Configuration Options |
Supported Port Modes on Slice 0 and Slice 1 |
|---|---|
|
Default |
1x100GE, 1x100GE, 10x10GE, and 10x10GE |
|
Option 1 |

1GbE Port Mode |
Release 7.7.1 |
You can now use the 1GbE port mode option to configure 10GbE optics speed on the SFP+ ports. This allows you to enable SFP+ ports on the line cards or router to deliver 1GbE standard traffic by using the hw-module location breakout command. This option is enabled on the following Cisco ASR 9000 Series router and line cards:
|
The Cisco ASR 9903 router has 16 QSFP28 ports and 20 integrated SFP+ ports with a maximum of 1.6T data bandwidth capacity. You can configure the ports in various port modes (100GbE, 25GbE, 10GbE, and 1GbE) using the hw-module location <node id> bay <bay number> port <port number> breakout <interface> command.
For more information on the ports, see the Installing Modules and Cables in the Chassis chapter in the Cisco ASR 9000 Series Fixed-Port Routers Hardware Installation Guide.

Cisco ASR 9000 series router supports the operating of one or all power modules. For example, V1 DC, V2 DC, V3 AC and V3 DC.
Ideally, you’re expected to connect all the power modules (or feed) to power supply. If you don’t connect any one feed, the system raises an alarm or error message.
You can configure the single-feed power mode to suppress the error message or an alarm for any missing feeds.
The following example enables the single power feed mode for the 0/PS2/M0/SP power module:
Router#admin
Router(admin)#config
Router(admin-config)#power single-feed location 0/PS2/M0/SPThe following sections provide references related to hardware management on Cisco IOS XR software.
