Overview
This section describes the HP ESCON PA, including channel attachment, the LED functions, the memory and cable requirements, and contains the following subsections:
•LEDs
•Port Adapter Slot Locations on the Supported Platforms
•Identifying Interface Addresses
Port Adapter Overview
The HP ESCON PA is a high-speed (100 bandwidth points) port adapter for Cisco 7200 series routers, including the Cisco 7200 VXR routers, that supports IP Datagram, TCP/IP Offload, TN3270 Server, TCP Assist, Cisco MultiPath Channel (CMPC), CMPC+, and Cisco SNA (CSNA) software applications.
The HP ESCON PA provides a single channel interface for Cisco 7200 series routers
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.
In some situations, this interface can eliminate the need for a separate front-end processor (FEP). The HP ESCON PA contains one ESCON I/O connector.
The HP ESCON PA (Figure 1) provides a single channel attachment interface for connecting Cisco 7200 series routers to an ESCON director or to a mainframe channel.
Note The Cisco 7200 series routers support the OIR of all port adapter types.
Figure 1 ESCON Channel Port Adapter, Faceplate View
The HP ESCON PA has a single female duplex connector and has 128 MB of DRAM. There are no memory options for the HP ESCON PA.
You can install the HP ESCON PA in any of the available port adapter slots in a Cisco 7200 series router. Figure 2 shows an HP ESCON PA installed in port adapter slot 1 of a Cisco 7206.
Figure 2 Cisco 7206 with an HP ESCON PA in Port Adapter Slot 1
Note The HP ESCON PA supports online insertion and removal (OIR), which allows you to install or remove an HP ESCON PA while the system is operating without shutting down system power.
The entire HP ESCON PA microcode image is delivered on a router Flash memory card or SanDisk memory device, or you can download it from Cisco.com.
•When ordered as a spare, the HP ESCON PA microcode is available via Cisco.com.
•When ordered as part of a new system, the HP ESCON PA 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 shipped with a new system, there is a default setting in Cisco IOS that points to the HP ESCON PA 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 HP ESCON PA microcode image onto the port adapter when the router boots and when an HP ESCON PA is inserted into a router that has already been booted.
We recommend that you use the version of the HP ESCON PA microcode that is virtually bundled with your Cisco IOS software. If you choose not to, you must 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 the microcode image you copied instead of the microcode image virtually bundled with your version of the Cisco IOS software.
•For instructions on placing HP ESCON PA microcode on the router Flash memory card, see the "Copying a New Image to the Flash Memory Card on a Cisco 7200 Series Router" section.
•For instructions on placing HP ESCON PA microcode on the SanDisk memory device, see the "Using SanDisk Devices" section.
•For instructions on configuring Cisco IOS to use an HP ESCON PA image from the router Flash memory card or SanDisk memory device, refer to the "Configuring the HP ESCON PA Microcode" section.
•For general information on HP ESCON PA microcode, refer to the "HP ESCON PA 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 "Upgrading the HP ESCON PA Microcode from Cisco.com" section.

Port Adapter Slot Locations on the Supported Platforms
The following sections provide port adapter slot locations and related information:
•Cisco 7200 Series Routers and Cisco 7200 VXR Routers Slot Numbering
Cisco 7200 Series Routers and Cisco 7200 VXR Routers Slot Numbering
Cisco 7204 routers and Cisco 7204VXR routers have four slots for port adapters, and one slot for an input/output (I/O) controller. The slots are numbered from the lower left to the upper right, beginning with slot 1 and continuing through slot 4. You can place a port adapter in any of the slots (slot 1 through slot 4). Slot 0 is always reserved for the I/O controller. The Cisco 7204 router and Cisco 7204VXR router are not shown.
Cisco 7206 routers and Cisco 7206VXR routers have six slots for port adapters, and one slot for an input/output (I/O) controller. The slots are numbered from the lower left to the upper right, beginning with slot 1 and continuing through slot 6. You can place a port adapter in any of the six slots (slot 1 through slot 6). Slot 0 is always reserved for the I/O controller. Figure 6 shows the slot numbering on a Cisco 7206 router. The Cisco 7206VXR router is not shown.
Note Interface ports are numbered from left to right starting with 0.
Figure 6 Port Adapter Slots in the Cisco 7206 Router
Identifying Interface Addresses
This section describes how to identify the interface addresses for the port adapter slots and ESCON channel port numbers. Interface 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 HP ESCON PA is installed.
•The second number identifies the interface port on the HP ESCON PA, which is always numbered as interface 0 for the HP ESCON PA.
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 HP ESCON PA 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.
Note The HP ESCON PA is considered a high-speed 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.
The following subsections describe the interface address formats for the supported platforms:

In Cisco 7200 series routers, port adapter slot numbers port adapter slots are numbered from the lower left to the upper right, beginning with port adapter slot 1 and continuing through port adapter slot 4 for the Cisco 7204, and slot 6 for the Cisco 7206. Port adapter slot 0 is reserved for the optional Fast Ethernet port on the I/O controller. For ESCON ports, the individual interface port numbers are always 0.
The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. For example, the ESCON port on an HP ESCON PA in port adapter slot 3 would have the address 3/0. If the HP ESCON PA was in port adapter slot 1, the interface address would be 1/0.

HP ESCON PA 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 adapter type. At system startup or reload, the system loads the microcode for each port adapter type present in the system.
The entire HP ESCON PA 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 HP ESCON PA port adapters) use the same microcode image.
By default, the HP ESCON PA microcode is loaded from the router Flash memory card or SanDisk memory device for the Cisco 7200 series routers. The default HP ESCON PA 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 microcodeMicrocode images for downloadable hardwareHW Type Microcode image names------------------------------------------ecpa default slot0:xcpa28-0configured slot0:xcpa218-2pcpa default slot0:xcpa28-0
Note In Cisco IOS Release 12.1(5)T or later, the filenames of all released HP ESCON PA microcode images use the conventions xcpa28-nn (for example, xcpa28-1). Interim pre-release versions of HP ESCON PA microcode images use the convention xcpa218-nnn (for example, xcpa218-2).
Hardware and Software Requirements
The show version command displays the current hardware configuration of the router, including the system software version that is loaded and running. For the HP ESCON PA, the show microcode command lists the recommended and the configured microcode version. The show controller command shows the microcode version running on the HP ESCON PA in the router.
To view the current version of software or microcode stored on the router Flash memory card, use the show flash slot0: or the dir slot0: EXEC commands. Refer to the "Upgrading Your HP ESCON PA Microcode" section for basic configuration information.
If the displays indicate that the required system software and microcode are not available in your system, refer to the "Obtaining Documentation, Obtaining Support, and Security Guidelines" section or contact a service representative for upgrade information.
The following subsections indicate the minimum hardware and software requirements for each supported platform:
•Cisco 7200 Series Routers and Cisco 7200 VXR Routers Hardware and Software Requirements
Cisco 7200 Series Routers and Cisco 7200 VXR Routers Hardware and Software Requirements
The minimum hardware and software requirements for the HP ESCON PA on Cisco 7200 series and Cisco 7200 VXR series routers are:
•The HP ESCON PA is used in the Cisco 7200 series routers and can be installed in any available port adapter slot.
•The Cisco 7200 series router requires a minimum of 32 MB of dynamic RAM (DRAM). The HP ESCON PA is a high-speed interface (100 bandwidth points).
Note For port adapter hardware and memory configuration guidelines for the Cisco 7200 series routers, refer to the document Cisco 7200 Series Port Adapter Hardware Configuration Guidelines at the following URL: http://www.cisco.com/en/US/products/hw/modules/ps2033/products_configuration_guide_book09186a00801056ef.htm
•The HP ESCON PA requires that the Cisco 7200 series router is running Cisco IOS Release 12.1(5)T or later.
Table 4 lists the specific Cisco IOS software images that are compatible with the HP ESCON PA.
Table 5 specifies the recommended minimum level of HP ESCON PA microcode for the corresponding Cisco IOS release.

Safety Guidelines
This section provides safety guidelines that you should follow when working with any equipment that connects to electrical power or telephone wiring.
Safety Warnings
Safety warnings appear throughout this publication in procedures that, if performed incorrectly, might harm you. A warning symbol precedes each warning statement.
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 Electrostatic Discharge Damage
Electrostatic discharge (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 HP ESCON PA 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 HP ESCON PA 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 HP ESCON PA 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.

Removing and Installing Port Adapters
This section describes how to remove port adapters from supported platforms and also how to install new or replacement port adapters.This section contains the following subsections:
•Port Adapter Removal and Installation
•Attaching the HP ESCON PA to the Channel
Handling Port Adapters
Each port adapter circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge (ESD) damage.
Note When a slot is not in use, a blank port adapter must fill the empty slot to allow the router or switch to conform to electromagnetic interference (EMI) emissions requirements and to allow proper airflow across the installed 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.
Caution Always handle the port adapter by the carrier edges and handle; never touch the port adapter components or connector pins. Always use an ESD wrist strap when handling equipment. (See Figure 7.)
Figure 7 Handling a Port Adapter
Online Insertion and Removal
The Cisco 7200 series routers, including Cisco 7200 VXR routers, support online insertion and removal (OIR) of all port adapters. You do not need to power down the router when removing and replacing an HP ESCON PA.
Note As you disengage the module from the router or switch, OIR administratively shuts down all active interfaces in the port adapter.
OIR allows you to install and replace port adapters while the router is operating; you do not need to notify the software or shut down the system power, although you should not run traffic through the port adapter you are removing while it is being removed. OIR is a method that is seamless to end users on the network, maintains all routing information, and preserves sessions.
It is wise to gracefully shut down the system before removing a port adapter that has active traffic moving through it. Removing a module while traffic is flowing through the ports can cause system disruption. Once the port adapter is inserted, the ports can be brought back up.
The following is a functional description of OIR for background information only; for specific procedures for installing and replacing a port adapter in a supported platform, refer to the "Port Adapter Removal and Installation" section.
Each port adapter has a bus connector that connects it to the router. The connector has a set of tiered pins in three lengths that send specific signals to the system as they make contact with the port adapter. The system assesses the signals it receives and the order in which it receives them to determine if a port adapter is being removed from or introduced to the system. From these signals, the system determines whether to reinitialize a new interface or to shut down a disconnected interface.
Specifically, when you insert a port adapter, the longest pins make contact with the port adapter first, and the shortest pins make contact last. The system recognizes the signals and the sequence in which it receives them.
When you remove or insert a port adapter, the pins send signals to notify the system of changes. The router then performs the following procedure:
1. Rapidly scans the system for configuration changes.
2. Initializes newly inserted port adapters or administratively shuts down any vacant interfaces.
3. Brings all previously configured interfaces on the port adapter back to their previously installed state. Any newly inserted interface is put in the administratively shutdown state, as if it was present (but not configured) at boot time. If a similar port adapter type is reinserted into a slot, its ports are configured and brought online up to the port count of the originally installed port adapter of that type.
Note Before you begin installation, read the "Required Tools and Equipment" section for a list of parts and tools required for installation.
Port Adapter Removal and Installation
In this section, the illustrations that follow give step-by-step instructions on how to remove and install port adapters. Although the procedures may refer to a particular type of port adapter, the steps are the same for installing and removing all types of port adapters. This section contains the following illustrations:
•Cisco 7200 Series Routers and Cisco 7200 VXR Routers—Removing and Installing a Port Adapter
Caution When performing the following procedures, wear a grounding wrist strap to avoid ESD damage to the card. Some platforms have an ESD connector for attaching the wrist strap.
Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034
Caution When powering off the router, wait a minimum of 30 seconds before powering it on again.

Attaching the HP ESCON PA to the 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.
To attach the ESCON cable between the HP ESCON PA and the host channel:
Step 1 Use the shutdown interface command on the router to shut down the HP ESCON PA 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 HP ESCON PA will be attached.
Note 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 HP ESCON PA and the host channel (Figure 8). Make certain the ESCON cable plug "clicks" in place in the receptacle on the HP ESCON PA. Connection problems may result if the plug does not click in place.
Step 3 Visually inspect the connection to make sure it is not loose.
Figure 8 Connecting an ESCON Cable to an HP ESCON PA
Step 4 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 5 Use the no shutdown interface configuration command to enable the HP ESCON PA interface.
Configuring the HP ESCON PA
To continue your port adapter installation, you must configure the HP ESCON PA interface. The instructions that follow apply to all supported platforms. Minor differences among the platforms—with Cisco IOS software commands—are noted.
This section contains the following subsections:
•Using the EXEC Command Interpreter
•Configuring the HP ESCON PA Interface
•Upgrading Your HP ESCON PA Microcode
•Running HP ESCON PA Diagnostic Tests
Using the EXEC Command Interpreter
You modify the configuration of your router through the software command interpreter called the EXEC (also called enable mode). 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 system 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 level:
Step 1 At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a privileged-level password as follows:
Router> enablePassword: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 (#):

After you verify that the new HP ESCON PA 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 3). Before you begin to configure the interface, be prepared with the following information:
•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. For more information on these special services, see the Cisco IOS Bridging and IBM Networking Configuration Guide.
If you installed a new HP ESCON PA interface or if you want to change the configuration of an existing interface, you must enter configuration mode to configure the new interfaces. If you replaced an HP ESCON PA that was previously configured, the system will recognize the new HP ESCON PA interface and bring it up in its existing configuration. An HP ESCON PA removed from one slot and replaced in another slot must be reconfigured.
Note Configuration commands are executed from the privileged level of the 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 HP ESCON PA interface:
•Performing a Basic Interface Configuration
Performing a Basic Interface Configuration
This section describes the procedure for performing a basic configuration of an HP ESCON PA interface.
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# disableRouter>The following example describes a basic configuration procedure:
Step 1 Enter configuration mode and specify that the console terminal will be the source of the router configuration commands, as follows:
Router# configure terminalEnter 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 following example prepares you to configure the interface on the channel port adapter in slot 2, port 0:
Router(config)# interface channel 2/0Step 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 1.1.1.10 255.255.255.0Step 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 shutdownStep 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#
For complete descriptions of interface subcommands and the configuration options available for each platform, refer to the publications listed in the "Related Documentation" section.
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. This section includes the following subsections:
•Using show Commands to Verify the New Interface Status
•Using the Ping Command to Verify Network 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 HP ESCON PA 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 the Ping Command to Verify Network Connectivity
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 1.1.1.10Type 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 msRouter#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 each platform, refer to the publications listed in the "Related Documentation" section.
Upgrading Your HP ESCON PA Microcode
The following sections discuss HP ESCON PA microcode configuration requirements:
•How Does HP ESCON PA Microcode Ship?
•Upgrading the HP ESCON PA Microcode from Cisco.com
•Configuring the HP ESCON PA Microcode
For additional information about specific microcode requirements, refer to the "Hardware and Software Requirements" section.
How Does HP ESCON PA Microcode Ship?
For the Cisco 7200 series routers, when the HP ESCON PA is ordered as part of a new system, the HP ESCON PA 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 HP ESCON PA is ordered as a spare, the HP ESCON PA microcode is available via Cisco.com.
Note The HP ESCON PA-compatible microcode images are virtually bundled with all Cisco IOS releases that support HP ESCON PAs. The virtual bundling of the microcode means that the microcode software is loaded separately by the Cisco IOS software.
Upgrading the HP ESCON PA Microcode from Cisco.com
To upgrade the HP ESCON PA microcode obtained from Cisco.com, complete the following steps:
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 12.1(5)T or later. For information on upgrading your Cisco IOS software, refer to the appropriate software configuration publication listed in the "Hardware and Software Requirements" section.
Caution The microcode ECPA commands in this section will affect both the HP ESCON PA and earlier versions of the ECPA if both types of port adapters are installed in the router.
To upgrade HP ESCON PA microcode images obtained from Cisco.com:
Step 1 Download the HP ESCON PA microcode image from Cisco.com to a TFTP server.
Step 2 Remove any configuration commands that specify a HP ESCON PA microcode image from the running configuration.
Step 3 Copy the HP ESCON PA microcode image to the Flash memory card in slot 0 or slot1, or to the SanDisk memory device in disk 0 or disk 1.
Step 4 Reconfigure the router, as necessary, to use the HP ESCON PA microcode image stored in the Flash memory card in slot 0 or slot 1, or in the SanDisk memory device in disk 0 or disk 1.
Step 5 Save your running configuration to a TFTP server, Flash memory, or SanDisk memory.
Step 6 Perform a microcode reload.
Configuring the HP ESCON PA 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 HP ESCON PA 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 system configuration file.
Note If you are running any image other than the default HP ESCON PA microcode and you want to upgrade to a later version of Cisco IOS software and use the default HP ESCON PA microcode that comes with that later Cisco IOS version, you must remove the microcode ecpa slot:filename statement from the system configuration file. If you do not remove the microcode ecpa slot:filename statement from the system configuration file, the Cisco IOS software will try to load the old version of the HP ESCON PA microcode.
To instruct the system to load an HP ESCON PA 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 (xcpa28-1 is used in this example):

Step 1 Enter the privileged EXEC configuration mode using the enable command:
Router> enablePassword:Router#
Note For complete information on the privileged EXEC configuration mode, refer to the "Using the EXEC Command Interpreter" section.
Step 2 If you need to copy a new HP ESCON PA microcode image to your router's Flash memory, refer to the "Using Flash Memory" section, then proceed to Step 3.
Step 3 In privileged EXEC configuration mode, enter global configuration mode and specify that the console terminal will be the source of the configuration subcommands:
Router# configure terminalTo 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 HP ESCON PA microcode image, and the exact argument for filename (xcpa28-1 is used in this example):
Router(config)# microcode ecpa slot0:xcpa28-1Router(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:xcpa28-1Step 4 To save the configuration file, press Ctrl-Z (or type end), then copy the new configuration to NVRAM:
Router# copy running-config startup-configStep 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 HP ESCON PA.
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 a New Image to the Flash Memory Card on a Cisco 7200 Series Router
•Using Additional Flash Memory Commands
•Recovering from Locked Blocks
Copying a New Image 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 12.0:

Note In the preceding example, the exclamation points (!) appear as the file is downloaded, and the "c" characters signify calculation of the checksum, which is a verification that the file has been correctly downloaded to the Flash memory card.
Using Additional Flash Memory Commands
There are additional commands related to the bootflash Flash memory in the Cisco 7200 series router (called bootflash) and in 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# pwdslot0You can move between Flash memory media using the cd [bootflash: | slot0: | slot1:] command:
Router# cd slot0:slot0Router# cd slot1:Router# pwdslot1You can list the directory of any Flash memory media using the dir [ bootflash: | slot0: | slot1: ] command:

Router# delete slot0:fun1Router# dir-#- -length- -----date/time------ name1 4601977 May 19 2000 09:42:19 myfile16 679 May 19 2000 05:43:56 todays-configTo 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.
You can permanently removes files, which are marked as deleted, and push together all other undeleted files to eliminate spaces between them using the squeeze command:
Router# squeeze slot0:All deleted files will be removed, proceed? [confirm]Squeeze operation may take a while, proceed? [confirm]ebESZTo 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:
•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:xcpa27-12283972 bytes available on device flash, proceed? [confirm]Address or name of remote host [biff.cisco.com]? [confirm]Source filename [xcpa27-1]?

Step 1 Enter the following commands, beginning in global configuration mode:
Router# configuration termRouter(config)# microcode ecpa diskX:xcpaXX-YYRouter(config)# microcode reloadRouter(config)# endwhere:
–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 HP ESCON PA Diagnostic Tests
The HP ESCON PA 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 HP ESCON PA. Contact a service representative to obtain the appropriate wrap plugs
