PA-1C-E ESCON Channel Port Adapter
Installation and Configuration


Product Number: PA-1C-E(=)

This document contains instructions for installing and configuring the Enterprise Systems Connection (ESCON) IBM Channel Port Adapter (PA-1C-E), which is used in the Cisco 7200-series routers.

For complete descriptions of interface configuration commands and the configuration options available for Cisco 7200-series interfaces that support the ESCON Channel Port Adapter functionality, refer to the appropriate software configuration publication listed in the "Obtaining Documentation" section.


Note Cisco IOS Release 11.3(3)T and later supports the ESCON Channel Port Adapter. When ordered as a spare, the ESCON Channel Port Adapter microcode is available via Cisco.com. When ordered as part of a new system, the ESCON Channel Port Adapter microcode is available on Flash memory cards and SanDisk memory devices (which also include the Cisco IOS release compatible with the microcode version) and via Cisco.com. When the ESCON Channel Port Adapter is shipped with a new system, there is a default setting in Cisco IOS that points to the ESCON Channel Port Adapter microcode with which it has been virtually bundled (separately bundled and preloaded onto the Flash memory card or SanDisk memory device along with the compatible Cisco IOS software). The Cisco IOS software loads the ESCON Channel Port Adapter microcode image onto the port adapter when the router boots and when an ESCON Channel Port Adapter is inserted into a router that has already been booted.

We recommend that you use the version of the ESCON Channel Port Adapter microcode that is virtually bundled with your Cisco IOS software. If you choose not to, you must then copy a microcode image onto the router Flash memory card or SanDisk memory device and use the microcode router configuration command to instruct the Cisco IOS software to use this microcode image instead of the microcode image virtually bundled with your version of the Cisco IOS software.

For instructions on placing ESCON Channel Port Adapter microcode on the router Flash memory card, see the "Copying to the Flash Memory Card on a Cisco 7200-Series Router" section.

For instructions on placing ESCON Channel Port Adapter microcode on the SanDisk memory device, see the "Using SanDisk Devices" section.

For instructions on configuring Cisco IOS to use an ESCON Channel Port Adapter image from the router Flash memory card or SanDisk memory device, refer to the "Configuring Microcode" section.

For general information on ESCON Channel Port Adapter microcode, refer to the "ESCON Channel Port Adapter Microcode Overview" section. For specific instructions to configure the Cisco IOS software to download microcode from the router Flash memory card or SanDisk memory device, refer to the "ESCON Channel Port Adapter Microcode Upgrade Overview" section.

ESCON Channel Port Adapter Microcode Overview

Microcode, also known as firmware, is a set of processor-specific software instructions that enables and manages the features and functions of a specific port adaptor type. At system startup or reload, the system loads the microcode for each port adaptor type present in the system.

The entire ESCON Channel Port Adapter microcode image is delivered on a router Flash memory card or SanDisk memory device, or you can download it from Cisco.com.

New microcode is released to enable new features, improve performance, or fix known problems in earlier versions. The Cisco 7200-series routers support downloadable software and microcode images for most upgrades. This support lets you download new or upgraded images remotely, store the images in router memory, and load the new images at system startup without physically accessing the router. You can store multiple versions of an image in Flash or SanDisk memory for a specific processor type, and use configuration commands to specify which version of the image loads at startup. All port adapters of the same type (for example, all ESCON Channel Port Adapters) use the same microcode image.


Caution To ensure proper operation of the ESCON channel, and to prevent system problems, you should use only the default ESCON Channel Port Adapter microcode image that is recommended for the Cisco IOS release you are running, unless directed otherwise by Cisco support personnel (see  Table 2).

By default, the ESCON Channel Port Adapter microcode is loaded from the router Flash memory card or SanDisk memory device for the Cisco 7200-series routers. The default ESCON Channel Port Adapter microcode version is found by entering the show microcode command.

The following example is a partial display of the show microcode command output:

Router# show microcode
Microcode images for downloadable hardware
HW Type             Microcode image names
------------------------------------------
ecpa     default    slot0:xcpa26-1
         configured slot0:xcpa214-10
pcpa     default    slot0:xcpa26-1

(additional display text omitted from this example)


Note In Cisco IOS Release 11.3(3)T or later, the filenames of all released ESCON Channel Port Adapter microcode images use the conventions xcpa26-nn (for example, xcpa26-1). Interim prerelease versions of ESCON channel microcode images use the convention xcpa214-nnn (for example, xcpa214-10).

Electrical Equipment Guidelines

Follow these basic guidelines when working with any electrical equipment:

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

Disconnect all power and external cables before moving a chassis.

Do not work alone when potentially hazardous conditions exist and never assume that power has been disconnected from a circuit; always check.

Do not perform any action that creates a potential hazard to people 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.

Preventing ESD Damage

ESD damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Port adapters and processor modules comprise printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use a preventive antistatic strap during handling.

The following guidelines help prevent 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 or midplane. These devices prevent accidental removal, provide proper grounding for the system, and help to ensure that bus connectors are properly seated.

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 component board-side-up on an antistatic surface or in a static shielding container. If you plan to return the component to the factory, immediately place it 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 For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohm.

Laser LED Safety Information

The ESCON Channel Port Adapter contains laser LEDs. The expansion module is classified as a Class 1 laser product and is certified to conform to the requirements of EN60825-1:1994 and IEC825-1:1993.

Class 1 laser products are not considered hazardous. The ESCON Channel Port Adapter has embedded Class 3a laser LED assemblies operating at a nominal wavelength of 850 nanometer and a maximum potential output power of 1.25 milliwatts. The design of the ESCON Channel Port Adapter incorporates engineering features including current limiting, which ensures that there is no human access to LED radiation greater than Class 1 under any set of operating, maintenance, or service conditions, including a single fault.

There are fewer than 0.442 milliwatts propagating in the link or in any portion of the module. Therefore, according to IEC825-2:1993, Hazard Level 1 prevails in all parts of the system.

The LEDs are located on the front face of the module.

What is the ESCON Channel Port Adapter

This section discusses channel attachment and the ESCON Channel Port Adapter, its LED functions, and its memory and cable requirements.

The following information is included in this section:

Channel Attachment Overview

ESCON Channel Port Adapter Overview

ESCON Channel Port Adapter Description

Channel Attachment Overview

A mainframe channel (referred to as a channel) is an intelligent processor that manages the protocol on the communications media and controls the data transfer to and from the main central processing unit (CPU) storage. Devices called input/output processors (IOPs) communicate between the host CPU and the channel. One IOP controls multiple channels. There is no relationship between the number of CPUs and the number of IOPs.

The channel relieves the mainframe CPU of direct communication with input/output (I/O) devices, which saves processing cycles and allows data processing and communications tasks to run concurrently. Channels use one or more channel paths as the links between mainframes and I/O devices. I/O devices are connected directly to control units, which provide the logical capabilities required to operate and control the I/O devices.

ESCON Channel Port Adapter Overview

An ESCON Channel Port Adapter provides a single channel interface for Cisco 7200-series routers. In some situations, this interface can eliminate the need for a separate front-end processor (FEP). The ESCON Channel Port Adapter contains an ESCON I/O connector.

The ESCON Channel Port Adapter is a high-bandwidth port adapter. A Fast Ethernet port adapter is an example of another type of high-speed port adapter. A single Cisco 7200-series router can support up to three high-speed port adapters.


Note The ESCON Channel Port Adapter supports online insertion and removal (OIR), which allows you to install or remove an ESCON Channel Port Adapter while the system is operating without shutting down system power.


ESCON Channel Port Adapter Description

The following information is included in this section:

Using the EXEC Command Interpreter

Configuring ESCON Channel Port Adapter Interface

You can install the ESCON Channel Port Adapter in any of the available port adapter slots in a Cisco 7200-series router. Figure 7 shows an ESCON Channel Port Adapter installed in port adapter slot 1 of a Cisco 7206.

Figure 7 Cisco 7206 with an ESCON Channel Port Adapter in Port Adapter Slot 1


Caution When powering off the router, wait a minimum of 30 seconds before powering it on again.

Installing or Replacing a Port Adapter in Cisco 7200-Series Routers


Note The Cisco 7200-series routers support OIR. You do not need to power down the Cisco 7200-series routers when removing and replacing ESCON Channel Port Adapters.


When a port adapter slot is not in use, a blank port adapter must fill the empty slot to allow the router to conform to EMI emissions requirements and to allow proper air flow across the port adapters. If you plan to install a new port adapter in a slot that is not in use, you must first remove the blank port adapter.

The following sections describe how to remove and replace a port adapter:

Removing a Port Adapter

Replacing a Port Adapter

Removing a Port Adapter

You do not need to power down the Cisco 7200-series routers when removing and replacing ESCON Channel Port Adapters; however, to prevent a possible interface control check on the mainframe, consult with your system administrator to take appropriate precautions.

The following procedure describes how to remove a port adapter from a Cisco 7200-series router:


Step 1 Attach an ESD wrist strap to your wrist and an unfinished chassis surface.

Step 2 Place the port adapter lever for the desired port adapter slot in the unlocked position. The port adapter lever remains in the unlocked position (Figure 8).

Figure 8 Placing the Port Adapter Lever in the Unlocked Position (Cisco 7206)

Step 3 Grasp the handle on the port adapter and pull the port adapter from the midplane until it is about halfway out of its slot. If you are removing a blank port adapter, pull the blank port adapter from the chassis slot.


Note As you disengage the port adapter from the router midplane, OIR administratively shuts down all active interfaces on the port adapter.


Step 4 With the port adapter halfway out of the slot, disconnect all cables from the port adapter.

Step 5 After disconnecting the cables, pull the port adapter from its chassis slot.


Caution Always handle the port adapter by the carrier edges and handle; never touch the port adapter's components or connector pins ( Figure 9).

Figure 9 Handling a Port Adapter

Step 6 Place the port adapter on an antistatic surface with its components facing upward or place in a static shielding bag. If the port adapter will be returned to the factory, immediately place it in a static shielding bag.


Replacing a Port Adapter

The following procedure describes how to replace a port adapter in a Cisco 7200-series router:


Step 1 Attach an ESD wrist strap to your wrist and an unfinished chassis surface.

Step 2 Use both hands to grasp the port adapter by its metal carrier edges and position the port adapter so that its components are downward (Figure 9).

Step 3 Align the left and right edges of the port adapter metal carrier between the guides in the port adapter slot (Figure 10).

Figure 10 Align the Port Adapter Metal Carrier Between the Slot Guides (Cisco 7206)

Step 4 With the metal carrier aligned in the slot guides, gently slide the port adapter halfway into the slot.


Caution Do not slide the port adapter all the way into the slot until you have connected all required cables. Trying to do so will disrupt normal operation of the router.

Step 5 With the port adapter halfway in the slot, connect all required cables to the port adapter.

Step 6 After connecting all required cables, carefully slide the port adapter all the way into the slot until you feel the port adapter's connectors mate with the midplane.

Step 7 After feeling the connectors mate, move the port adapter lever to the locked position. Figure 11 shows the port adapter lever in the locked position.


Note If the port adapter lever does not move to the locked position, the port adapter is not completely seated in the midplane. Carefully pull the port adapter halfway out of the slot, reinsert it, and move the port adapter lever to the locked position.


Figure 11 Port Adapter Lever in the Locked Position (Cisco 7206)


Attaching the ESCON Channel Port Adapter to the Channel

The following procedure describes how to attach the ESCON cable between the ESCON Channel Port Adapter and the host channel.


Caution We recommend that an authorized service representative or other qualified service person perform the following procedure. To prevent hardware problems with your host processor, all the channel connections must be tight. A loose connection can cause the host processor or its channel to halt. Every cable must be tightly seated in its connector.


Step 1 Use the shutdown interface command on the router to shut down the ESCON Channel Port Adapter interface. This action prevents excessive error messages from being sent to the router log output. In addition, we recommend that you vary offline the host channel to which the ESCON Channel Port Adapter will be attached. For instructions on how to vary offline the host channel, refer to the documentation for your mainframe operating system.

Step 2 Attach an ESCON cable between the ESCON Channel Port Adapter and the host channel (Figure 12). Make certain the ESCON cable plug "clicks" in place in the receptacle on the ESCON Channel Port Adapter. Connection problems may result if the plug does not click in place. Visually inspect the connection to make sure it is not loose.

Figure 12 Connecting an ESCON Cable to the ESCON Channel Port Adapter

Step 3 Vary online the host channel. For instructions on how to vary the host channel online, refer to the documentation for your mainframe operating system.

Step 4 Use the no shutdown interface configuration command to enable the ESCON Channel Port Adapter interface.


Using the EXEC Command Interpreter

You modify the configuration of your router through the software command interpreter called the EXEC. You must enter the privileged level of the EXEC command interpreter with the enable command before you can use the configure command to configure a new interface or to change the existing configuration of an interface. The EXEC command interpreter prompts you for a password if one has been set.

The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>). At the console terminal, use the following procedure to enter the privileged EXEC level:


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

Router> enable
Password: 

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

Step 3 When you enter the correct password, the system displays the privileged-mode system prompt (#):

Router#


Proceed to the following section to configure the new interfaces.

Configuring ESCON Channel Port Adapter Interface

If you installed a new ESCON Channel Port Adapter or if you want to change the configuration of an existing interface, you must use the privileged EXEC configure command. If you remove and replace an ESCON Channel Port Adapter in the same slot that was previously configured, the system will recognize the new ESCON Channel Port Adapter interface and bring it up in its existing configuration. An ESCON Channel Port Adapter removed from one slot and replaced in another slot must be reconfigured.

After you verify that the new ESCON Channel Port Adapter is installed correctly, use the configure command to configure the new interfaces. The enabled LED (EN) goes on when the port adapter is installed correctly (Figure 4). Be prepared with the information you will need to configure the interface, including the following:

Protocols and encapsulations you plan to use on the new interfaces.

Protocol-specific information, such as internet protocol (IP) addresses if you will configure the interfaces for IP routing.

Special services you plan to use on the interface, such as Common Link Access for Workstations (CLAW), offload support, TN3270 server support, CIP SNA, or Cisco MultiPath Channel.


Note Configuration commands are executed from the privileged EXEC command interpreter, which usually requires password access. Refer to the "Using the EXEC Command Interpreter" section and contact your system administrator, if necessary, to obtain access.


The following sections provide specific information about configuring the ESCON Channel Port Adapter interface:

Selecting Port Adapter Slots and ESCON Channel Port Numbers

Configuring Interfaces

Checking the Configuration

For complete descriptions of interface subcommands and the configuration options available for Cisco 7200-series interfaces, refer to the publications listed in the "Related Documentation" section.

Selecting Port Adapter Slots and ESCON Channel Port Numbers

This section describes how to identify port adapter slots and ESCON channel port numbers.

Physical port addresses specify the actual physical location of each interface port on the router. This address is composed of a two-part number in the format port adapter slot number/interface port number, as follows:

The first number identifies the port adapter slot in which the ESCON Channel Port Adapter is installed.

The second number identifies the interface port on the ESCON Channel Port Adapter, which is always numbered as interface 0 for the ESCON Channel Port Adapter.


Note Some IBM channel attach software features are configured on a virtual port. On the CIP cards installed in a Cisco 7500-series router, there are up to two physical ports, numbered 0 and 1, and a virtual port, numbered 2. However, on the ESCON Channel Port Adapter installed in a Cisco 7200-series router, the single physical port and the virtual port are configured using the same port number identifier, number 0.


Interface ports maintain the same address regardless of whether other port adapters are installed or removed from the slot. However, when you move a port adapter to a different slot, the first number in the address changes to reflect the new port adapter slot number.

The port adapter slot numbers start with 1 and continue through 6. Slot 0 is always reserved for the Fast Ethernet port on the I/O controller. The individual interface port numbers are always 0. For example, the ESCON port on an ESCON Channel Port Adapter in port adapter slot 3 would have the address 3/0. If the ESCON Channel Port Adapter was in port adapter slot 1, this same interface port would be 1/0.

You can identify interface ports by physically checking the slot/interface port location on the front of the router or by using show commands to display information about a specific interface or all interfaces in the router.


Note The ESCON Channel Port Adapter is considered a high-bandwidth port adapter; there are specific configuration guidelines that must be observed. Refer to the publication Cisco 7200 Series Port Adapter Hardware Configuration Guidelines (Document Number 78-3471-xx), which shipped with your Cisco 7200-series chassis and is also available on the Cisco Connection Documentation, Enterprise Series CD-ROM.


Configuring Interfaces

This section describes the procedure for performing a basic configuration of the interfaces on ESCON Channel Port Adapters installed in a Cisco 7200-series router.

Press the Return key after each step unless otherwise noted. At any time you can exit the privileged level and return to the user level by entering disable at the prompt as follows:

Router# disable
Router> 

The following example describes a basic configuration procedure:


Step 1 At the privileged EXEC prompt, enter configuration mode and specify that the console terminal will be the source of the router configuration commands, as follows:

Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#

Step 2 At the prompt, enter the interface configuration mode by using the interface configuration command. The example that follows prepares you to configure the interface on the channel port adapter in slot 2, port 0:

Router(config)# interface channel 2/0

Step 3 If IP routing is enabled on the system, you can assign an IP address and subnet mask to the interface with the ip address interface configuration, as in the following example:

Router(config-if)# ip address 1.1.1.10 255.255.255.0

Step 4 Add any additional configuration subcommands required to enable routing protocols and set the interface characteristics.

Step 5 Change the shutdown state to up and enable the interface as follows:

Router(config-if)# no shutdown

Step 6 Configure additional interfaces as required.

Step 7 When you have included all configuration commands to complete the configuration, press Ctrl-Z to exit configuration mode. You may also type end to exit configuration mode and return to the EXEC prompt.

Step 8 Write the new configuration to nonvolatile memory as follows:

Router# copy running-config startup-config
[OK]
Router#

Step 9 To check the interface configuration using show commands, see the "Checking the Configuration" section.


Checking the Configuration

After configuring the new interface, use the show commands to display the status of the new interface or all interfaces and use the ping command to check connectivity.

Using show Commands to Verify the New Interface Status

Use show commands to verify that the new interfaces are configured and operating correctly, as follows:


Step 1 Display the system hardware configuration with the show version command. Ensure that the list includes the new interfaces.

Step 2 Display all the current port adapters and their interfaces with the show controllers command. Verify that the new ESCON Channel Port Adapter appears in the correct slot.

Step 3 Specify one of the new interfaces with the show interfaces port adapter type slot/interface 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. Display the configuration stored in nonvolatile RAM (NVRAM) using the show startup-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 up the interface, contact a service representative for assistance.


Using show Commands to Display Interface and System Information

Use the show interfaces type slot/port command to display information about a specific interface. The following example of the show interfaces channel slot/port command shows all of the information specific to the ESCON Channel Port Adapter in port adapter slot 5:

Router# show interfaces channel 5/0

Using the Ping Command to Verify Network Connection

Use the ping command 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. This section provides brief descriptions of the ping command. After you verify that the system has booted successfully and is operational, you can use the ping command to verify the status of interface ports.

The ping command sends an echo request out to a remote device at the 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 time-out 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.

The following example shows a successful ping command to a remote server with the IP address 1.1.1.10:

Router# ping 1.1.1.10 
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echoes to 1.1.1.10, 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, then repeat the ping command.

For complete descriptions of interface configuration commands and the configuration options available for Cisco 7200-series interfaces and functions, refer to the publications listed in the "Related Documentation" section.

ESCON Channel Port Adapter Microcode Guidelines

The following sections discuss ESCON Channel Port Adapter microcode configuration requirements:

How Does ESCON Channel Port Adapter Microcode Ship?

ESCON Channel Port Adapter Microcode Upgrade Overview

Configuring Microcode

For additional information about specific microcode requirements, refer to the "ESCON Channel Port Adapter Microcode Overview" section.

How Does ESCON Channel Port Adapter Microcode Ship?

For the Cisco 7200-series routers, when the ESCON Channel Port Adapter is ordered as part of a new system, the Channel Port Adapter microcode is available on a Flash memory card or SanDisk memory device (which also includes the Cisco IOS release compatible with the microcode version) and via Cisco.com. When the ESCON Channel Port Adapter is ordered as a spare, the Channel Port Adapter microcode is available via Cisco.com.


Note The ESCON Channel Port Adapter-compatible microcode images are virtually bundled with all Cisco IOS releases that support ESCON Channel Port Adapter. The virtual bundling of the microcode means that the microcode software is loaded separately by the Cisco IOS software.


ESCON Channel Port Adapter Microcode Upgrade Overview

To upgrade the ESCON Channel Port Adapter microcode obtained from Cisco.com, complete the steps in the following procedures.


Note Perform the following procedure only if you are upgrading your microcode.



Caution To prevent system problems in the following procedure, you must be running Cisco IOS Release 11.3(3)T or later. For information on upgrading your Cisco IOS software, refer to the appropriate software configuration publication listed in the "Related Documentation" section.

Upgrading from Cisco.com

To upgrade ESCON Channel Port Adapter microcode images obtained from Cisco.com, do the following:


Step 1 Download the Channel Port Adapter microcode image from Cisco.com to a TFTP server.

Step 2 Remove any configuration commands that specify a Channel Port Adapter microcode image from the running configuration.

Step 3 Copy the Channel Port Adapter microcode image to the Flash memory card in slot 0 or slot1, or to the SanDisk memory device in disk0 or disk1.

Step 4 Reconfigure the router, as necessary, to use the Channel Port Adapter microcode image stored in the Flash memory card in slot 0 or slot 1, or in the SanDisk memory device in disk0 or disk1.

Step 5 Save your running configuration to a TFTP server, Flash memory card, or SanDisk memory device.

Step 6 Perform a microcode reload.


Configuring Microcode

This section describes how to modify the startup configuration to load different microcode images at startup, or to change existing configuration instructions and re-enable the system default.

At system startup or reload, the system loads a microcode image for each processor type. All processors of the same type use the same microcode image; only one image for each type can load at startup. The ESCON Channel Port Adapter microcode image must be located on a Flash memory card or SanDisk memory device.

When you upgrade software or microcode by downloading new images onto a Flash memory card or SanDisk memory device, you must configure the system to load the new microcode image at startup. Otherwise, the system will continue to load the default image from the system or attempt to load any previous image if it is still specified in the configuration file.


Note If you are running anything other than the default ESCON Channel Port Adapter microcode with your Cisco IOS software and you want to upgrade to a later version of Cisco IOS software, and want to use the default ESCON Channel Port Adapter microcode that comes with that later version, you must remove the microcode ecpa slot:filename statement from the system configuration file, otherwise the Cisco IOS software will try to load that old version of the ESCON Channel Port Adapter microcode.


To instruct the system to load an ESCON Channel Port Adapter microcode image other than the default at startup, use the microcode ecpa slot:filename and the microcode reload configuration commands to add the instructions to the configuration file.

To load a microcode image from a file stored on a Flash memory card, enter the show flash slot0: EXEC command to display the Flash directory contents and verify the exact name of the file (xcpa26-1 is used in this example):

Router> show flash slot0:

Perform the following steps to configure the microcode for an ESCON Channel Port Adapter on a router configured with Cisco IOS Release 11.3(3)T or later:


Step 1 Enter the privileged EXEC mode command interpreter:

Router> enable
Password:
Router#

Note For complete information on the command interpreter and software functions, refer to the publications listed in the "Related Documentation" section.


Step 2 If you need to copy a new ESCON Channel Port Adapter microcode image to your router's Flash memory, refer to the "Using Flash Memory" section, then proceed to Step 3.

Step 3 In privileged command mode, enter router configuration mode and specify that the console terminal will be the source of the configuration subcommands:

Router# configure terminal

To load the microcode from an individual microcode image that is stored as a file on a Flash memory card, enter the microcode command, the processor type, the specific memory location of the ESCON Channel Port Adapter microcode image, and the exact argument for filename (xcpa26-1 is used in this example):

Router(config)# microcode ecpa slot0:xcpa26-1 
Router(config)# microcode reload 


Note The microcode reload command is written automatically in the configuration file following the microcode ecpa command when you modify the system default to load a microcode image.


The no microcode command cancels any existing instructions to load an image from a Flash memory card and restores the default configuration:

Router(config)# no microcode ecpa slot0:xcpa26-1 

Step 4 To save the configuration file, press Ctrl-Z (or type end), then copy the new configuration to NVRAM:

Router# copy running-config startup-config

Step 5 To verify that the correct microcode is loaded according to the new instructions, enter the show controllers EXEC command. The display indicates the currently loaded and running microcode version for each Channel Port Adapter.

Step 6 To verify the contents of the configuration file, enter the show running-config EXEC command. You can also verify that the correct software image is configured to load at system restart or reload by using the show startup-config EXEC command.


Using Flash Memory

The following provides information on the different functions of Flash memory that you might need when configuring microcode:

Copying to the Flash Memory Card on a Cisco 7200-Series Router

Additional Flash Memory Commands

Recovering from Locked Blocks

Copying to the Flash Memory Card on a Cisco 7200-Series Router

Copying a new image to a Flash memory card might be required when a new microcode image becomes available. Use the command copy tftp:filename [ bootflash | slot0 | slot1 ]:filename for the copy procedure, where tftp:filename is the source of the file and [ bootflash | slot0 | slot1 ]:filename is the destination in onboard Flash memory or on either of the Flash memory cards. The following example shows the output from the copy tftp:filename command for Cisco IOS Release 11.3:

Router# copy tftp:xcpa26-1 slot0:xcpa26-1
2283972 bytes available on device flash, proceed? [confirm]

Note In the preceding example, the exclamation points (!) appear as the file is downloaded, and the "v" characters signify calculation of the checksum, which is a verification that the file has been correctly downloaded to the Flash memory card.


Additional Flash Memory Commands

There are additional commands related to the bootflash Flash memory in the Cisco 7200-series router (called bootflash) and in Personal Computer Memory Card International Association (PCMCIA) Flash memory cards. The following example assumes you are currently accessing the Flash memory card in PCMCIA slot 0. You can determine which PCMCIA slot you are accessing using the pwd command as follows:

Router# pwd
slot0

You can move between Flash memory media using the cd [bootflash: | slot0: | slot1:] command:

Router# cd slot0:
slot0
Router# cd slot1:
Router# pwd
slot1

You can list the directory of any Flash memory media using the dir [ bootflash: | slot0: | slot1: ] command:

Router# dir
-#- -length- -----date/time------ name
1   4601977  May 19 1994 09:42:19 myfile1
6   679      May 19 1994 05:43:56 todays-config
7   1        May 19 1994 09:54:53 fun1

You can delete a file from any Flash memory media using the delete command:

Router# delete slot0:fun1
Router# dir
-#- -length- -----date/time------ name
1   4601977  May 19 1994 09:42:19 myfile1
6   679      May 19 1994 05:43:56 todays-config

To verify that the delete command was successful, use the dir /deleted command to view the deleted files.


Note Files that are deleted are simply marked as deleted, but still occupy space in Flash memory. To remove the files, use the squeeze command.


The squeeze command permanently removes files, which are marked as deleted, and pushes together all other undeleted files to eliminate spaces between them.

The following example shows the squeeze command:

Router# squeeze slot0:
All deleted files will be removed, proceed? [confirm]
Squeeze operation may take a while, proceed? [confirm]
ebESZ

To prevent loss of data because of sudden power loss, the "squeezed" data is temporarily saved to a special location of Flash memory.

In the squeeze command display output, the displayed characters have the following meaning:

The character "e" means the Flash memory special location has been erased, which occurs before a write operation.

The character "b" means that the data that is about to be written to this special location has been temporarily copied.

The character "E" signifies that the sector that was temporarily occupied by the data has been erased.

The character "S" signifies that the data was written to its permanent location in Flash memory.

The character "Z" means this log was erased after the successful squeeze command operation.

The squeeze command automatically tracks which of these functions has been performed so upon sudden power failure, it can safely continue with the process.

Recovering from Locked Blocks

A locked block of Flash memory occurs when power is lost or a Flash memory card is unplugged during a write or erase operation. When a block of Flash memory is locked, it cannot be written to or erased, and the operation will consistently fail at a particular block location. The only way to recover from locked blocks is by reformatting the Flash memory card with the format command.


Caution Formatting a Flash memory card to recover from locked blocks will cause existing data to be lost.

Using SanDisk Devices

PCMCIA Flash memory cards use a slot0/slot1 convention to specify memory locations; slot0 is the default directory for IOS searches. However, SanDisk memory devices use a disk0/disk1 convention. Therefore, when you use a SanDisk device on a Cisco 7200-series router, you need to specify disk0 or disk1 explicitly in IOS search arguments.

For example, to copy a new microcode image to a Sandisk device, use the following command:

copy tftp:source_filename {disk0|disk1}:sandisk_filename

where:

tftp:source_filename is the source location of the microcode image file

sandisk_filename is the destination on disk0 or disk1 of the SanDisk memory card

The following example shows sample output for the copy tftp:filename command:

Router# copy tftp:xcpa27-1 disk0:xcpa27-1
2283972 bytes available on device flash, proceed? [confirm]
Address or name of remote host [biff.cisco.com]? [confirm]

To update your running configuration:


Step 1 Enter the following commands, beginning in global configuration mode:

Router# configuration term
Router(config)# microcode ecpa diskX:xcpaXX-YY
Router(config)# microcode reload
Router(config)# end

where:

diskX is disk0 or disk1 on the SanDisk device

xcpaXX-YY is the xCPA image you want to use, such as xcpa27-1

Step 2 Save the running configuration to NVRAM.


Running ESCON Channel Port Adapter Diagnostic Tests

The ESCON Channel Port Adapter diagnostic test routines are as follows:

Processor test 1

Processor test 2

I/O device tests

Serial link controller (SLC) device tests

Internal electrical wrap

External optical wrap for the ESCON Channel Port Adapter


Note All diagnostic tests are run every time the adapter is started. They cannot be run independently. The external optical wrap test require special wrap plugs for the ESCON Channel Port Adapter. Contact a service representative to obtain the appropriate wrap plugs.
