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
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:

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
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.

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

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
Router> enablePassword:Step 2
Step 3
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:
•
•
•
Note
The following sections provide specific information about configuring the ESCON Channel Port Adapter interface:
•
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:
•
•
Note
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
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# disableRouter>The following example describes a basic configuration procedure:
Step 1
Router# configure terminalEnter configuration commands, one per line. End with CNTL/Z.Router(config)#Step 2
Router(config)# interface channel 2/0Step 3

Step 5
Router(config-if)# no shutdownStep 6
Step 7
Step 8
Router# copy running-config startup-config[OK]Router#Step 9
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
Step 2
Step 3
Step 4
Step 5
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:
