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 allowsdata 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 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 on page 36.

• For instructions on placing HP ESCON PA microcode on the SanDisk memory device, see the

“Using SanDisk Devices” section on page 38.

• 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 on page 34.

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.

Port adapter slot 0

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 PortAdapter HardwareConfiguration 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:

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.

Required Tools and Equipment

You need the following parts and tools to install an HP ESCON PA. If you need additional equipment, contact a service representative for ordering information.

• HP ESCON PA

• ESCON interface cables

• ESD-prevention equipment or the disposable grounding wrist strap included with all upgrade kits,

field-replaceable units (FRUs), and spares

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.
