Cisco 7304 PCI Port Adapter Carrier Card Installation and Configuration Guide


Product Numbers: 7300-CC-PA=

Introduction

This document describes the Cisco 7304 Peripheral Component Interconnect (PCI) port adapter carrier card (7300-CC-PA=), hereafter referred to as the 7300-CC-PA, which is an option available for use with Cisco 7304 routers. The 7300-CC-PA makes it possible to use Cisco 7200 series and Cisco 7500 series PCI port adapters on the Cisco 7304 router.

The Cisco 7304 router hosts centralized processing on a network services engine (NSE) or network processing engine (NPE). The 7300-CC-PA acts as a pass-through device so that the NSE or NPE processes all packets from a PCI port adapter installed on a Cisco 7304 router.

The 7300-CC-PA supports one single-width port adapter. For a list of supported port adapters, refer to the "Port Adapter Support" section.

Specifications

System Software

The 7300-CC-PA has a main processor and fixed memory. Interfaces located on port adapters that fit into the 7300-CC-PA connect the router to the external network. Each 7300-CC-PA accepts one single-width port adapter.

Although the 7300-CC-PA supports OIR, individual port adapters do not. For this reason, remove the 7300-CC-PA first before removing or installing port adapters.

The 7300-CC-PA supports Automatic Line Card Recovery (ALCR), a feature that speeds recovery of a failed router by reloading a failed line card without reloading other line cards on the network backplane. For more information, refer to the "Automatic Line Card Recovery" section.

The 7300-CC-PA installs in any of the four module slots on the Cisco 7304 router. For more information on module slots on Cisco 7304 routers, refer to the Cisco 7304 Router Installation and Configuration Guide or the Cisco 7304 Router Quick Start Guide.

ROM Monitor

The 7300-CC-PA read-only memory (ROM) monitor, known as ROMmon, is firmware. It runs a brief set of system diagnostics, initializes the 7300-CC-PA hardware, and downloads the Cisco IOS image for the 7300-CC-PA from the Cisco 7304 router IOS image.

Starting in Cisco IOS Release 12.2(28)SB, a 7300-CC-PA ROMmon upgrade procedure was introduced. If 7300-CC-PA ROMmon is incompatible, the 7300-CC-PA will not operate until the 7300-CC-PA ROMmon incompatability is addressed. If you are running a previous version of Cisco IOS, including any version of Cisco IOS Release 12.2SBC, 12.2S, or even earlier Cisco IOS releases, the 7300-CC-PA ROMmon upgrade does not apply to you.
See Upgrading PCI Port Adapter Carrier Card ROMmon for additional information regarding 7300-CC-PA ROMmon upgrades.

Port Adapter Support

Each 7300-CC-PA supports one single-width port adapter.

The 7300-CC-PA does not support OIR of port adapters. To install or replace port adapters, first remove the 7300-CC-PA.


Note A 7300-CC-PA requires a port adapter be installed in order to be supported.


Table 3 lists the port adapters supported by the 7300-CC-PA at the time of this writing.

Electrical Equipment Guidelines

Follow these basic guidelines when working with any electrical equipment:

Before beginning any procedures requiring access to the router interior, locate the emergency power-off switch for the room in which you are working.

Disconnect all power and external cables before moving a router.

Do not work alone when potentially hazardous conditions exist.

Never assume that power has been disconnected from a circuit; always check.

Do not perform any action that creates a potential hazard or makes the equipment unsafe.

Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

Telephone Wiring Guidelines

Use the following guidelines when working with any equipment that is connected to telephone wiring or to other network cabling:

Never install telephone wiring during a lightning storm.

Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.

Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.

Use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures.

Use the following guidelines for preventing ESD damage:

Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.

Connect the equipment end of the strap to an unfinished chassis surface.

When installing a component, use any available ejector levers or captive installation screws to properly seat the bus connectors in the backplane.

When removing a component, use any available ejector levers or captive installation screws to release the bus connectors from the backplane or midplane.

Handle carriers by available handles or edges only; avoid touching the printed circuit boards or connectors.

Place a removed board component-side-up on an antistatic surface or in a static shielding container.

Avoid contact between the printed circuit boards and clothing. The wrist strap only protects components from ESD voltages on the body; ESD voltages on clothing can still cause damage.

Never attempt to remove the printed circuit board from the metal carrier.


Caution Only trained and qualified personnel should be allowed to install, replace, or service this equipment.


Caution This equipment is to be installed and maintained by service personnel only as defined by AZ/NZS 3260 Clause 1.2.14.3 Service Personnel.


Caution Do not work on the system or connect or disconnect cables during periods of lightning activity.


Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms (Mohms).

Online Insertion and Removal

7300-CC-PA Removal and Installation

Guidelines

This section describes the correct procedures to avoid unnecessary board failures. Follow these guidelines when removing and installing the 7300-CC-PA:

Remove the 7300-CC-PA from the router before removing or installing a port adapter into a 7300-CC-PA.

Handle the 7300-CC-PA by the carrier edges only; never touch the board or any connector pins. (See Figure 3.)

Figure 3 Handling a 7300-CC-PA

Install the 7300-CC-PA in router module slots 2 through 5. See Figure 4 for module slot numbering on a Cisco 7304 router.

Figure 4 Module Slots on the Cisco 7304 Router

Remove or insert only one 7300-CC-PA at a time. Allow the system time to complete the initialization process before removing or inserting another 7300-CC-PA. Disrupting the sequence can cause the system to detect spurious hardware failures. When initialization is complete, the console displays a message indicating a state change, such as:

%LINK-5-CHANGED: Interface FastEthernet2/0, changed state to administratively down

Insert a module filler plate into any unused module slot. Do not install an empty 7300-CC-PA (one that does not contain a port adapter) into a router.


Note When a module slot is not in use, a module filler plate must fill the empty slot to allow the router to conform to electromagnetic interference (EMI) emissions requirements and to allow proper airflow through the router. If you plan to install a 7300-CC-PA into a module slot that is not in use, you must first remove the module filler plate.


Online Insertion and Removal

The Cisco 7304 router supports online insertion and removal (OIR) of 7300-CC-PAs; therefore, you do not have to power down the router when removing and replacing a 7300-CC-PA on a Cisco 7304 router. The Cisco 7304 router also supports CLI-controlled OIR, which allows for the completion of data traffic before the active interfaces are shut down.


Note CLI-controlled OIR is the recommended way of performing OIR on this platform.



Note As you disengage the 7300-CC-PA from the router, online insertion and removal (OIR) administratively shuts down all active interfaces on the 7300-CC-PA.



Note OIR of a port adapter installed in a 7300-CC-PA is not allowed. It is not possible to remove a port adapter from a 7300-CC-PA that is installed in a Cisco 7304 router. The port adapter lock cannot be moved to its unlocked and vertical position until the 7300-CC-PA is removed from the router.


CLI-Controlled OIR

7300-CC-PAs can be removed from the Cisco 7304 router without disrupting data flow by using the hw-module slot slot # stop/start command in EXEC mode. The hw-module slot slot # stop command stops traffic, shuts down all 7300-CC-PA interfaces, and deactivates the 7300-CC-PA. The hw-module slot slot # start command resets the 7300-CC-PA, puts the 7300-CC-PA back online, and turns off the OIR LED.


Note Upon insertion of a 7300-CC-PA, the system automatically activates the card. The hw-module slot
slot # start command is only necessary when reactivating an installed 7300-CC-PA that has been deactivated with the hw-module slot slot # stop command.


The following shows how to remove and install an active 7300-CC-PA in slot 2:

Router# hw-module slot 2 stop

When the OIR LED turns green, the 7300-CC-PA in slot 2 has been deactivated and can be physically removed and replaced with another 7300-CC-PA. (See the "7300-CC-PA Removal and Installation" section).

When another 7300-CC-PA is inserted into slot 2, it is automatically reset, put online, and the OIR LED is turned off.

7300-CC-PA Removal and Installation

This section provides step-by-step instructions for removing and installing a 7300-CC-PA.


Caution Remove or insert only one 7300-CC-PA at a time. Disrupting the sequence before the system has completed verification can cause the system to detect spurious hardware failures.


Warning When performing the following procedures, wear a grounding wrist strap to avoid ESD damage to the 7300-CC-PA. Some platforms have an ESD connector for attaching the wrist strap. Do not directly touch the midplane or backplane with your hand or any metal tool, or you could shock yourself.


To remove and install a 7300-CC-PA, refer to Figure 5 and do the following:


Step 1 To remove the 7300-CC-PA, loosen the locking thumbscrews on both sides of the 7300-CC-PA, as shown in A of Figure 5.

Step 2 Pull out the 7300-CC-PA ejector levers, as shown in B of Figure 5, and carefully slide the 7300-CC-PA halfway out of the module slot. If you are removing a module filler plate, pull the module filler plate completely out of the module slot.

Step 3 With the 7300-CC-PA halfway out of the module slot, disconnect all cables from the port adapter. After disconnecting the cables, pull the 7300-CC-PA out of the module slot.

Step 4 To insert the 7300-CC-PA, carefully align the edges of the 7300-CC-PA between the upper and lower edges of the module slot, as shown in C of Figure 5.

Step 5 Carefully slide the 7300-CC-PA halfway into the module slot and connect all cables to the port adapter.

Step 6 With the cables connected, carefully slide the 7300-CC-PA into the module slot until the 7300-CC-PA makes contact with the backplane.


Note The 7300-CC-PA ejector levers must be positioned at a 45-degree angle before the 7300-CC-PA makes contact with the backplane.


Step 7 Push the 7300-CC-PA ejector levers in until the 7300-CC-PA is fully seated in the router backplane.


Note When the router chassis is fully populated, seating a 7300-CC-PA can be difficult. To properly seat the 7300-CC-PA and avoid physical damage, loosen the locking thumbscrews on the neighboring 7300-CC-PAs or line cards.



Caution Use of excessive force can damage the router or 7300-CC-PA.

Step 8 Tighten the locking thumbscrews on both sides of the 7300-CC-PA.


Figure 5 illustrates how to remove and install a 7300-CC-PA into a Cisco 7304 router. As is required, the 7300-CC-PA is populated with a port adapter.

Figure 5 7300-CC-PA Removal and Installation

Removing and Installing a Port Adapter

This section describes how to remove and install a port adapter into a 7300-CC-PA. It includes the following sections:

Guidelines

Port Adapter Removal and Installation

Port Adapter Configuration

Guidelines

This section describes the correct procedures to avoid unnecessary board failures. Follow these guidelines when removing and installing a port adapter in a 7300-CC-PA:

Because individual port adapters do not support OIR, you must first remove the 7300-CC-PA before removing or installing a port adapter. Refer to the "Removing and Installing a 7300-CC-PA" section if you have not already removed the 7300-CC-PA.

Handle port adapters by the carrier edges and handle; never touch the board or any connector pins. (See Figure 6.)

Figure 6 Handling a Port Adapter

Insert a blank port adapter into an unused 7300-CC-PA port adapter slot. Use a blank port adapter to fill the empty slot to allow the router to conform to EMI emissions requirements and to allow proper airflow through the router. Do not install an empty 7300-CC-PA (one that does not contain a port adapter) in a router.

No OIR for Port Adapters

OIR of a port adapter installed in a 7300-CC-PA is not allowed. It is not possible to remove a port adapter from a 7300-CC-PA that is installed in a Cisco 7304 router. The port adapter lock cannot be moved to its unlocked and vertical position until the 7300-CC-PA is removed from the router.

Port Adapter Removal and Installation

You can install one single-width port adapter in a 7300-CC-PA. This section provides step-by-step instructions for removing and installing a port adapter in a 7300-CC-PA.


Warning When performing the following procedures, wear a grounding wrist strap to avoid ESD damage to the 7300-CC-PA. Some platforms have an ESD connector for attaching the wrist strap. Do not directly touch the midplane or backplane with your hand or any metal tool, or you could shock yourself.


To remove and install a port adapter in a 7300-CC-PA, refer to Figure 7 and do the following:


Step 1 If the 7300-CC-PA is still in the router, you must remove the 7300-CC-PA before removing a port adapter.

Step 2 To remove the port adapter from the 7300-CC-PA, turn the port adapter lock from its locked and horizontal position shown in A of Figure 7 to its unlocked and vertical position shown in B of Figure 7.

Step 3 Grasp the handle of the port adapter and pull the port adapter from the 7300-CC-PA. (You have already disconnected the cables from the port adapter when removing the 7300-CC-PA).

Step 4 To insert the port adapter in the 7300-CC-PA, locate the guide rails inside the 7300-CC-PA that hold the port adapter in place. They are at the top left and top right of the port adapter slot and are recessed about an inch, as shown in C of Figure 7.

Step 5 Carefully slide the port adapter all the way in the 7300-CC-PA until the port adapter is firmly seated in the port adapter interface connector. When fully seated, the port adapter might be slightly behind the 7300-CC-PA faceplate.

Step 6 After the port adapter is properly seated, turn the port adapter lock to its locked and horizontal position, as shown in A of Figure 7.


Figure 7 illustrates how to remove and install a port adapter in a 7300-CC-PA.

Figure 7 Port Adapter Removal and Installation

Port Adapter Configuration

To configure the new interface, use the configuration section of the specific port adapter installation and configuration guide, or use the Cisco IOS software configuration documentation listed in the "Related Documentation" section. The documentation is available online on Cisco.com, and on the Documentation CD-ROM.

Performing a Basic 7300-CC-PA Configuration

After a 7300-CC-PA is installed, the system brings online only port adapter interfaces that match the current configuration and were previously configured as up; all others require that you configure them with the configure command.

To configure the interfaces on the port adapters installed on your 7300-CC-PA, first enable the router as described below.


Step 1 At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a privileged-level password as follows:

Router> enable
Password:

Step 2 Enter the password (the password is case sensitive). For security purposes, the password is not displayed.

When you enter the correct password, the system displays the privileged-level system prompt (#):

Router#

For a complete description of commands and configuration options available for your 7300-CC-PA, refer to the configuration section of the specific port adapter installation and configuration guide and to the appropriate Cisco IOS software configuration publications. (See the "Related Documentation" section.)

Checking the 7300-CC-PA Installation

This section describes the procedures you can use to verify your 7300-CC-PA installation, and includes information on the following topics:

Verifying the Installation

Using show Commands to Verify the 7300-CC-PA Status

Using show Commands to Display Interface Information

Using the ping Command to Verify Network Connectivity

Verifying the Installation

This section describes how to verify the 7300-CC-PA installation by observing the7300-CC-PA LED states, port adapter LED states, and the information displayed on your console terminal.

When the system has reinitialized all interfaces, the 7300-CC-PA STATUS LED should be on (green) and the ENABLED LED on the port adapters should go on (green), depending on your connections and configuration. The console screen also displays a message as the system discovers each interface during its reinitialization.


Note A Fast Ethernet interface is used in the following examples for illustrative purposes.


The following sample display shows the events logged by the system as a 7300-CC-PA with a Fast Ethernet port adapter was removed from module slot 3; the system then reinitializes the remaining interface processors and marks as down the Fast Ethernet interface on the 7300-CC-PA that was removed from slot 3.

Router# 
18:04:29: %OIR-6-REMCARD: Card removed from slot 3, interfaces disabled 
18:04:30: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet3/0, changed state 
to down 

When you reinsert the 7300-CC-PA, the system automatically brings up the interfaces that were up when the 7300-CC-PA was removed.

Router#
18:05:00: %OIR-6-INSCARD: Card inserted in slot 3, interfaces administratively shut down  
18:05:08: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet3/0, changed state 
to up 

Note When a new 7300-CC-PA is inserted or when a 7300-CC-PA is moved to a new slot, the system recognizes the new interfaces but leaves them in the shutdown state until you configure them and change their state to up.


The following sample display shows the events logged by the system as you insert a new 7300-CC-PA in module slot 3.

Router#
18:05:25: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet3/1, changed state 
to down 

Use the following procedure to verify that the 7300-CC-PA is installed correctly:


Step 1 Observe the console display messages and verify that the system discovers the 7300-CC-PA, while the system reinitializes each interface, as follows:

If you installed a new 7300-CC-PA, the STATUS LED should be on (green). The system should recognize all new interfaces but leave them configured as down.

If you replaced a 7300-CC-PA, the STATUS LED should be on (green). The system does not recognize each interface and places it in the administratively down state.

Step 2 Verify that the ENABLED LED on the port adapter goes on (is green) and remains on after the reinitialization is complete. If the ENABLED LED remains on, proceed to Step 5. If the ENABLED LED does not remain on, proceed to Step 3.

Step 3 If the ENABLED LED on a port adapter fails to go on, the port adapter or the 7300-CC-PA might not be fully seated even if the port adapter lock is in the locked and horizontal position. When a port adapter is not recognized, the 7300-CC-PA is deactivated, and its OIR LED is yellow.

Remove the 7300-CC-PA from the router.

Remove the port adapter from the 7300-CC-PA.

Inspect the 7300-CC-PA and the port adapter. Verify there are no bent pins or parts and that there is nothing lodged in the two devices that could prevent a good connection.

Insert the port adapter in the 7300-CC-PA by sliding the port adapter all the way in the 7300-CC-PA until the port adapter is firmly seated in the port adapter interface connector. When fully seated in the 7300-CC-PA, the port adapter might be slightly behind the 7300-CC-PA faceplate.

Insert the 7300-CC-PA into the router.

After the system reinitialization, the ENABLED LED on the port adapter should go on and remain on. If the ENABLED LED remains on, proceed to Step 5. If it does not, proceed to Step 4.

Step 4 If the ENABLED LED on a port adapter still fails to go on, remove the 7300-CC-PA and install it in another available slot on the router.

If the ENABLED LED goes on, suspect a failed backplane port in the original slot.

If the ENABLED LED fails to go on, remove the 7300-CC-PA and ensure the port adapter is firmly seated in its slot. Remove and reinstall it accordingly.

If the ENABLED LED still fails to go on, but other LEDs on the 7300-CC-PA port adapter go on to indicate activity, proceed to Step 5 to resume the installation checkout; suspect that the ENABLED LED on the port adapter has failed. Contact a service representative to report the problem and obtain further instructions.

If no LEDs on the port adapter go on:

Verify that the port adapter is supported on the 7300-CC-PA and that it has the required hardware revision. If the port adapter is not supported or has an old hardware revision, the show diag command indicates that the 7300-CC-PA is deactivated. (See Table 3 for required port adapter hardware revisions.)

Suspect a faulty 7300-CC-PA. Contact a service representative to report the problem and obtain further instructions.

Step 5 If the port adapter is new and not a replacement, configure the new interfaces using the configuration section of your port adapter installation and configuration guide.


Note New interfaces are not available until you configure them.


Step 6 If the 7300-CC-PA is a replacement, use the show interfaces type slot-number/port-number command or the show controllers command to verify the status of the interfaces. (See the "Using show Commands to Verify the 7300-CC-PA Status" section.)

If you replaced a 7300-CC-PA with another 7300-CC-PA with a different port adapter installed, the system recognizes the interfaces on the previously configured port adapter but does not recognize the new port adapter interfaces. The new interfaces remain in the shutdown state until you configure them.

Step 7 When the interfaces are up, check the activity of each interface by observing the status LEDs, which are described in the appropriate LED section of your port adapter installation and configuration guide.

Step 8 If an interface LED fails to go on and a cable is connected to the interface port, check the cable connection and make certain it is properly seated in the connector.

Step 9 Repeat Step 1 through Step 8 to verify that any additional 7300-CC-PAs are properly installed.


If you experience other problems that you are unable to solve, contact TAC (see the "Obtaining Technical Assistance" section) or a service representative for assistance.

To configure the new interface, use the configuration section of the specific port adapter installation and configuration guide or the Cisco IOS software configuration documentation listed in the "Related Documentation" section. The documentation is available online on Cisco.com and on the Documentation CD-ROM.

Using show Commands to Verify the 7300-CC-PA Status

The following steps use show commands to verify that the new interfaces are configured and operating correctly.


Step 1 Use the show version command to display the system hardware configuration. Ensure that the list includes the new interfaces.

Step 2 Display all the current interface processors and their interfaces with the show controllers command. Verify that the new 7300-CC-PA appears in the correct module slot.

Step 3 Specify one of the new interfaces with the show interfaces type slot-number/port-number command and verify that the first line of the display specifies the interface with the correct slot number. Also verify that the interface and line protocol are in the correct state: up or down.

Step 4 Display the protocols configured for the entire system and specific interfaces with the show protocols command. If necessary, return to configuration mode to add or remove protocol routing on the system or specific interfaces.

Step 5 Display the running configuration file with the show running-config command. Verify that the configuration is accurate for the system and each interface.

If the interface is down and you configured it as up, or if the displays indicate that the hardware is not functioning properly, ensure that the network interface is properly connected and terminated. If you still have problems bringing the interface up, contact a service representative for assistance.



Note The outputs that appear in this document may not match the output you receive when running these commands. The outputs in this document are examples only.


Using show Commands to Display Interface Information

This section describes using show commands to display interface information.

To display information about a specific interface, use the show interfaces command with the interface type and interface address in the format show interfaces type slot-number/port-number.

With the show interfaces command, use arguments such as the interface type and the interface address to display information about a specific interface only. The following example of the show interfaces fastethernet command shows information specific to a 7300-CC-PA with a Fast Ethernet port adapter (PA-2FE-TX) installed; the 7300-CC-PA is installed in module slot 3:

Using the ping Command to Verify Network Connectivity

This section provides brief descriptions of the ping command. The ping command allows you to verify that an interface port is functioning properly and to check the path between a specific port and connected devices at various locations on the network. After you verify that the system and the 7300-CC-PA have booted successfully and are operational, you can use this command to verify the status of the 7300-CC-PA port adapter interface ports. Refer to the publications listed in the "Related Documentation" section for detailed command descriptions and examples.

The ping command sends an echo request out to a remote device at an IP address that you specify. After sending a series of signals, the command waits a specified time for the remote device to echo the signals. Each returned signal is displayed as an exclamation point (!) on the console terminal; each signal that is not returned before the specified timeout is displayed as a period (.). A series of exclamation points (!!!!!) indicates a good connection; a series of periods (.....) or the messages [timed out] or [failed] indicate that the connection failed.

Following is an example of a successful ping command to a remote server with the IP address 10.1.1.60:

Router# ping 10.1.1.60 <Return>
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echoes to 10.1.1.60, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms
Router#

If the connection fails, verify that you have the correct IP address for the server and that the server is active (powered on), and repeat the ping command.

For complete descriptions of interface subcommands and the configuration options available for 7300-CC-PA-related interfaces, and which commands support 7300-CC-PA functionality, refer to the publications listed in the "Related Documentation" section.

Maintenance Procedures

The following sections discuss maintenance procedures you might need for your 7300-CC-PA and port adapters:

Automatic Line Card Recovery

FPGA Code and Upgrade

Upgrading PCI Port Adapter Carrier Card ROMmon

Automatic Line Card Recovery

The 7300-CC-PA automatically recovers from the following catastrophic errors:

Fatal serial link errors

7300-CC-PA local processor software crash

Loss of keepalive packets from 7300-CC-PA local processor

Hardware errors reported by 7300-CC-PA devices

Too many 7300-CC-PA error interrupts (more than 60 interrupts within 10 processor ticks)

If the 7300-CC-PA encounters more than five fatal errors within one hour, recovery will not be attempted and the 7300-CC-PA will be deactivated. To reactivate the 7300-CC-PA, use the hw-module slot slot # start command, or physically remove and replace the 7300-CC-PA.

The 7300-CC-PA crash history can be viewed by using the show diag slot command. The crash history is saved as long as the 7300-CC-PA is physically present in the chassis. Physically removing the 7300-CC-PA from the chassis or performing a CLI-controlled OIR will clear the crash history.

The following error messages are associated with line card (7300-CC-PA) recovery:

Error Message    00:00:06:% LC-3-RECOVERY: Line card (slot <x>) recovery in progress
Error Message    00:00:06:% LC-3-EXCESSERRORS: Number of errors seen on the line card 
(slot <x>) exceed the threshold

When the 7300-CC-PA encounters any of the nonrecoverable errors listed below, the 7300-CC-PA is deactivated and must be restarted by performing a CLI-controlled OIR or physically removing and installing the 7300-CC-PA.

7300-CC-PA hardware failures

7300-CC-PA local processor boot code/firmware initialization failure (failure to boot or boot code exceptions, firmware download failure)

Environmental critical conditions (voltage and temperature)

Insufficient system memory to allocate critical 7300-CC-PA driver data structures during 7300-CC-PA initialization

The following examples show nonrecoverable fatal error messages:

Error Message    00:00:06% ENVM-0-SHUTDOWN: Environmental Monitor initiated shutdown 
due to <voltage/temperature/power supply> in slot <x>
Error Message    00:00:06% PACC-0-DLL_OUTOFLOCK: PA Carrier Card HW DLLs failed to lock 
in linecard at slot <x>
Error Message    00:00:06% PACC-0-INITFAIL: PA Carrier Card initialization failure for 
slot <x>, FastEthernet <x>/<y>
Error Message    00:00:06% PACC-1-ALLOCFAIL: PA Carrier Card (slot <x>) <component> 
allocation failure
Error Message    00:00:06% PACC-3-NOPA: No Port Adapter detected in slot <x>
Error Message    00:00:06% PACC-3-REVNOTSUPPORTED: PA (type <number>) in slot <x> 
requires base h/w revision of (<number>) for this PA-CC 
Error Message    00:00:06% PACC-3-UNKNPA: Unrecognized Port Adapter in slot <x>
Error Message    00:00:06% PACC-3-UNSUPPORTED_PA: Unsupported Port Adapter (type 
<number>) in slot <x>

FPGA Code and Upgrade

Automatic FPGA version checking and update is performed during every system startup for all line cards, NSEs, and 7300-CC-PAs in the system. Automatic FPGA version checking and update is performed for a line card or 7300-CC-PA after insertion of that line card or 7300-CC-PA during an online insertion and removal (OIR).

You might need to update the FPGA image in order to add new features or incorporate caveat fixes. You can manually initiate the FPGA image update process by entering the upgrade fpga all command.

For detailed information about FPGA bundling and updating on the Cisco 7304 router, see the Cisco 7304 Series FPGA Bundling and Update document.

Upgrading PCI Port Adapter Carrier Card ROMmon

Starting in Cisco IOS Release 12.2(28)SB, a 7300-CC-PA ROMmon upgrade procedure was introduced. If 7300-CC-PA ROMmon is incompatible, the 7300-CC-PA will not operate until the 7300-CC-PA ROMmon incompatability is addressed. If you are running a previous version of Cisco IOS, including any version of Cisco IOS Release 12.2SBC, 12.2S, or even earlier Cisco IOS releases, the 7300-CC-PA ROMmon upgrade does not apply to you.
See Upgrading PCI Port Adapter Carrier Card ROMmon for additional information regarding 7300-CC-PA ROMmon upgrades.
