Overview
This section describes the HP ESCON PA, including channel attachment, the LED functions, the memory and cable requirements, and contains the following subsections:
•

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
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.

Note
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.
•
•
•
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.

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:
•
•
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.
Note
The following subsections describe the interface address formats for the supported platforms:
•
Table 3 describes the interface addresses for the Cisco 7200 series routers, includingCisco 7200 VXR routers.

Cisco 7200 Series Routers and Cisco 7200 VXR Routers Interface Addresses
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
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:

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:

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:
•
•
Handling Port Adapters
Each port adapter circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge (ESD) damage.
Note
Caution
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
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:

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
Router> enablePassword:Step 2

Configuring the HP ESCON PA Interface
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:
•
•
•
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
The following sections provide specific information about configuring the HP ESCON PA interface:
