Installation and Configuration
Product Number: PA-1C-P(=)
This document contains instructions for installing and configuring the Parallel Channel Port Adapter (PCPA), 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 PCPA functionality, refer to the appropriate software configuration publication listed in the "If You Need More Information" section.
Note
Cisco IOS Release 11.3(7)T or later or Release 12.0(1) or later supports the PCPA. When ordered as a spare, the PCPA microcode is available via Cisco.com. When ordered as part of a new system, the PCPA microcode is available on Flash memory cards or SanDisk memory devices (which also include the Cisco IOS software release compatible with the microcode version) and via Cisco.com. When the PCPA is shipped with a new system, there is a default setting in the Cisco IOS software that points to the PCPA 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 PCPA microcode image onto the PCPA when the router boots and when a PCPA is inserted into a router that has already been booted.
We recommend that you use the version of the PCPA 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 PCPA 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 PCPA microcode on the SanDisk memory device, see the "Using SanDisk Devices" section.
For instructions on configuring Cisco IOS software to use a PCPA image from the router Flash memory card or SanDisk memory device, refer to the "Configuring Microcode" section.
For general information on PCPA microcode, refer to the "PCPA 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 "PCPA Microcode Upgrade Overview" section.

PCPA 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.
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 port adapter 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 PCPAs) use the same microcode image.
Caution
The entire PCPA microcode image is delivered on a router Flash memory card or SanDisk memory device, or you can download it from Cisco.com.
By default, the PCPA microcode is loaded from the router Flash memory card or SanDisk memory device for the Cisco 7200 series routers. You can determine the default PCPA microcode version by entering the show microcode command.
The following example is a partial display of the show microcode command output:

What is the PCPA?
This section discusses channel attachment and the PCPA, 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.
PCPA Overview
A PCPA 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 PCPA contains a bus and tag (also called an original equipment manufacturer's interface [OEMI] and a parallel I/O interface) connector.
Note
PCPA Description

PCPA Bus and Tag Cables
This section includes descriptions and illustrations of the PCPA bus and tag cables.
•
•
•
Y Cable
The bus and tag cable with three 78-pin connectors (Figure 4) has a DB-78 male (PCA) connector on the port adapter end, a DB-78 female connector on the next-control-unit end, and a DB-78 male connector on the from-host end. This cable is referred to as the Y cable.
Figure 4 PCA Bus and Tag Cable (CAB-PCA-Y)
The male connector might be labeled IN and is typically black, but can also be a dark gray. The female connector might be labeled OUT and is typically light gray. The female OUT cable is nearest to the select/bypass switch.
Caution
On the rear of the PCA connector on the Y cable there is a switch marked S (for select mode) and B (for bypass mode) (Figure 5). The select/bypass switch is required to allow the cable to be separated from the PCPA without "opening" the select-out loop.
Caution
Figure 5 Select/Bypass Switch on the Rear of the PCA Connector on the Y Cable (CAB-PCA-Y Bypass Shown)
In select mode the PCPA is operational and the select-out signal is passed in a loop to all control lines on the channel. All control units have a relay that shorts the incoming select-out signal to the outgoing select-out signal when power is not applied to the control unit. When power is applied, the relay is opened, and the signal is passed to the PCPA.
Without the select/bypass switch in bypass mode, the channel would need to be taken offline before servicing or replacing PCPA. If the selected address does not match, the select-out signal is passed to the next control unit. If the select-out signal gets all the way back to the channel, the control unit being addressed is not present.
Note
Caution
VA and VB Cables
The two bus and tag cables with connector blocks have a DB-78 (male or female) connector on the port adapter end and 48-pin type-A connector blocks on the bus and tag ends (Figure 6). VA and VB cables are 56 inches (1.42 meters) long.
The bus and tag cable that attaches the host and the PCPA is referred to as the VA cable. The female 78-pin connector might be labeled IN and is typically light gray. The cable labeled P2 is bus, and the cable labeled P3 is tag. Looking into the end of the female 78-pin connector (on the VA cable), with the wide part of the connector D-shell on top, the P2 (bus) cable is on the right, and the P3 (tag) cable is on the left. The plastic on the ends of the bus and tag connectors might be black or dark gray. The Cisco VA cable ships with a terminator.
The bus and tag cable that attaches the next control unit and the PCPA is referred to as the VB cable. The male 78-pin connector might be labeled OUT and is typically black or dark gray. The cable labeled P2 is bus, and the cable labeled P3 is tag. Looking into the end of the male 78-pin connector (on the VB cable), with the wide part of the connector D-shell on top, the P2 (bus) cable is on the left, and the P3 (tag) cable is on the right. The plastic on the ends of the bus and tag connectors might be light gray (as opposed to the black or dark gray plastic on the VA cable).
Caution
Figure 6 PCA Bus and Tag, VA and VB Cables
The Y cable is always attached to the PCPA. The VA cable attaches the male end of the Y cable and the host. The VB cable attaches the female end of the Y cable and the next (or new) control unit. Do not connect the VB cable directly to the PCPA. If the PCPA is the last control unit, channel termination is required at the end of the Y cable that points away from the host (Figure 4). For attachment instructions refer to the "Attaching the PCPA to the Channel" section.
Caution
Using the PCPA in Cisco 7200 Series Routers
The following sections include information about using the PCPA in the Cisco 7200 series routers:

You can install the PCPA in any of the available port adapter slots in a Cisco 7200 series router. Figure 7 shows a PCPA installed in port adapter slot 1 of a Cisco 7206.
Figure 7 Cisco 7206 with a PCPA in Port Adapter Slot 1
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 PCPAs; 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:

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 interface.
Configuring PCPA Interface
If you installed a new PCPA 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 a PCPA in the same slot that was previously configured, the system will recognize the new PCPA interface and bring it up in its existing configuration. A PCPA removed from one slot and replaced in another slot must be reconfigured.
After you verify that the new PCPA is installed correctly, use the configure command to configure the new interface. The enabled LED (EN) goes on when the port adapter is installed correctly. 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 PCPA interface:
•
For complete descriptions of interface subcommands and the configuration options available for Cisco 7200 series interfaces, refer to the publications listed in the "If You Need More Information" section.
Selecting Port Adapter Slots and Parallel Channel Port Number
This section describes how to identify port adapter slots and the PCPA port number.
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 port on a PCPA in port adapter slot 3 would have the address 3/0. If the PCPA 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.
Configuring Interfaces
This section describes the procedure for performing a basic configuration of the interface on a PCPA 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
Router# copy running-config startup-config[OK]Router#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
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 PCPA in port adapter slot 5:

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 1.1.1.10Type 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 Cisco 7200 series interfaces and functions, refer to the publications listed in the "If You Need More Information" section.
PCPA Microcode Guidelines
The following sections discuss PCPA microcode configuration requirements:
•
•
For additional information about specific microcode requirements, refer to the "PCPA Microcode Overview" section.
How Does PCPA Microcode Ship?
For the Cisco 7200 series routers, when the PCPA 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 software release compatible with the microcode version) and via Cisco.com. When the PCPA is ordered as a spare, the Channel Port Adapter microcode is available via Cisco.com.
Note
PCPA Microcode Upgrade Overview
To upgrade the PCPA microcode obtained from Cisco.com, complete the steps in the following procedures.
Note
Caution
Upgrading from Cisco.com
To upgrade PCPA microcode images obtained from Cisco.com, do the following:
Step 1
Step 2
Step 3
Step 4
Step 5
Step 6
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 port adapter type. All port adapters of the same type use the same microcode image; only one image for each type can load at startup. The PCPA 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
To instruct the system to load a PCPA microcode image other than the default at startup, use the microcode pcpa 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 (xcpa26-4 is used in this example):
Router> show flash slot0:(additional displayed text omitted)-#- ED --type-- --crc--- -seek-- nlen -length- -----date/time------ name23 .. unknown 00000001 4930F8 11 1 Jan 20 1998 14:33:19 xcpa26-424 .. unknown 70908993 4E213C 23 323522 Jan 20 1998 14:33:19 xcpa26-4_kernel_xcpa25 .. unknown 5CD4E560 51A4F4 19 230200 Jan 20 1998 14:33:34 xcpa26-4_seg_80226 .. unknown 0954E702 56522C 20 306360 Jan 20 1998 14:33:44 xcpa26-4_seg_cmpc27 .. unknown 44575172 57A814 20 87400 Jan 20 1998 14:33:59 xcpa26-4_seg_csna28 .. unknown 1C73CFC5 5EB2F4 19 461408 Jan 20 1998 14:34:03 xcpa26-4_seg_eca29 .. unknown 090B4417 5FC0F4 23 68992 Jan 20 1998 14:34:24 xcpa26-4_seg_offload30 .. unknown BE20EFEA 60D064 19 69360 Jan 20 1998 14:34:28 xcpa26-4_seg_pca31 .. unknown 4A1D172A 610DB4 20 15568 Jan 20 1998 14:34:31 xcpa26-4_seg_push32 .. unknown 227EF97E 63D9C4 21 183184 Jan 20 1998 14:34:32 xcpa26-4_seg_tcpip33 .. unknown 249B5D63 6C8FBC 22 570744 Jan 20 1998 14:34:41 xcpa26-4_seg_tn3270(additional displayed text omitted)2927520 bytes available (17650784 bytes used)Perform the following steps to configure the microcode for a PCPA on a router configured with Cisco IOS Release 11.3(7)T or later or Release 12.0(1) or later:
Step 1

Router(config)# microcode pcpa slot0:xcpa26-4Router(config)# microcode reload
Note
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 pcpa slot0:xcpa26-4Step 4
Router# copy running-config startup-configStep 5
Step 6
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
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:
Router# copy tftp:xcpa26-4 slot0:xcpa26-42283972 bytes available on device flash, proceed?

Note
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# dir-#- -length- -----date/time------ name1 4601977 May 19 1994 09:42:19 myfile16 679 May 19 1994 05:43:56 todays-config7 1 May 19 1994 09:54:53 fun1You can delete a file from any Flash memory media using the delete command:
Router# delete slot0:fun1Router# dir-#- -length- -----date/time------ name1 4601977 May 19 1994 09:42:19 myfile16 679 May 19 1994 05:43:56 todays-configTo verify that the delete command was successful, use the dir /deleted command to view the deleted files.
Note
The squeeze command permanently removes files that 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]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 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
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_filenamewhere:
•
•
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]?
