1 The Catalyst RSM/VIP2 model recommended for the PA-A3 is the VIP2-40, which has 2 MB of SRAM and 32 MB of DRAM. The PA-A3 is not supported by the VIP2-15.

2 Currently, the Cisco uBR7246 VXR router supports only the PA-A3-OC3MM, PA-A3-OC3SMI, and PA-A3-OC3SML port adapters. In the future, however, the Cisco uBR7246 VXR will support both the PA-A3-E3 and PA-A3-T3 port adapters.


2 All PA-A3 port adapters shipped after November 1998 require Cisco IOS Release 11.1(22)CC or a later release of Cisco IOS Release 11.1CC to operate; they do not function on any software release before Release 11.1(22)CC.



Note Although PA-A3 port adapters purchased or received before November 1998 and installed on the VIP2 might continue to function properly in Cisco 7000 series routers, Cisco 7500 series routers, and Cisco 7200 series software releases before Cisco IOS Release 11.1(22)CC, you must upgrade to Cisco IOS Release 11.1(22)CC. This release can be ordered as Release 11.1(22)R to ensure software release consistency throughout your network and to prevent problems when you add new PA-A3 port adapters to your existing network.

You must use Cisco IOS Release 12.0(1) or later on the Catalyst RSM/VIP2.



Note When you upgrade your Cisco IOS software to the minimum required software release, we recommend you also upgrade your boot image.


The boot image for your upgraded Cisco IOS software release is available at Cisco.com. Instructions for downloading the boot image from a TFTP server are described in the "Upgrading Your Boot Flash Image" section.

To determine which revision of the PA-A3 is installed, use the show diag command. PA-A3 port adapters identified with board revision B0 require a minimum software release of Cisco IOS Release 11.1(22)CC for Cisco 7500 series routers and Cisco 7200 series routers.

The following example shows the new board revision number (B0) for a PA-A3-OC3MM installed in slot 1:

router# show diag 1
Slot 1:
         ATM WAN OC3 (MM) port adapter, 1 port
         Port adapter is analyzed 
         Port adapter insertion time 22:36:49 ago
         Hardware revision 1.0           Board revision B0

To determine if your router is compatible with the PA-A3, use the show version command to display the current hardware configuration of the router, including the system software version that is currently loaded and running. The show controllers command lists all interfaces (VIP and Catalyst RSM/VIP2 only) and gives the currently loaded and running microcode version for each. You can check the version of the default ROM image by either removing the board and checking the ROM labels, or by configuring the interface or system software to boot from ROM, restarting the system, and using these same commands to check the running version.

If a display indicates that the running system software is an earlier version than Cisco IOS Release 11.1(22)CC on Cisco 7500 series routers, Cisco 7000 series routers, or Cisco 7200 series routers, check the contents of Flash memory to determine whether the required images are available on your system. (Use the show flash command to display a list of all files stored in Flash memory.)

The following example of the show version command displays information about a Cisco 7200 series router running Cisco IOS Release 11.1(22)CC:

Hardware Requirements

This section describes the hardware requirements for the PA-A3 on the various supported platforms, and contains the following subsections:

Catalyst RSM/VIP2 in Catalyst 5000 Family Switches Hardware Requirements

Cisco 7100 Series Routers Hardware Requirements

Cisco 7200 Series Routers, Cisco 7200 VXR Routers, and Cisco uBR7200 Series Routers

Cisco 7201 Router Hardware Requirements

Cisco 7301 Router Hardware Requirements

Cisco 7304 PCI Port Adapter Carrier Card in Cisco 7304 Routers Hardware Requirements

Cisco 7401ASR Router Hardware Requirements

VIP in Cisco 7000 Series Routers and Cisco 7500 Series Routers Hardware Requirements

Catalyst RSM/VIP2 in Catalyst 5000 Family Switches Hardware Requirements

Following are the hardware requirements for the PA-A3 in Catalyst 5000 family switches:

The PA-A3 can be installed on the Catalyst RSM/VIP2-40 with the Route Switch Processor 2 (RSP2). The Catalyst RSM/VIP2-15 does not support the PA-A3.

On a Catalyst RSM/VIP2-40, you can have two PA-A3-T3 or PA-A3-E3 port adapters installed in adjacent slots or a port adapter of any other type installed in the adjacent slot with the exception of the PA-A3-OC3MM, PA-A3-OC3SMI, or PA-A3-OC3SML port adapters. You can have only one PA-A3-OC3 port adapter per Catalyst RSM/VIP2-40; no other port adapter can reside in the other port adapter slot.

The PA-A3 supports the DRAM and static RAM (SRAM) configurations used in the Catalyst RSM/VIP2-40 with 2 MB of SRAM and 32 MB of DRAM.

Cisco 7100 Series Routers Hardware Requirements

Following are the hardware requirements for the PA-A3 in Cisco 7100 series routers:

The OC-3c versions of the PA-A3 are high-bandwidth and must conform to the system configuration guidelines for Cisco 7100 series routers. (Port adapters are rated by data-carrying capacity as high, medium, or low bandwidth. Cisco 7100 series routers have certain data-carrying capacity [or bandwidth] restrictions that affect the number of high-, medium-, and low-bandwidth port adapters you can install.) Refer to the Cisco 7100 Series VPN Router Installation and Configuration Guide for more information on port adapter installation restrictions.

The T3 version of the PA-A3(PA-A3-T3) is a high-bandwidth port adapter, and the E3 version PA-A3-E3 is a medium-bandwidth port adapter. Both versions must follow the system configuration guidelines for Cisco 7100 series routers. Refer to the Cisco 7100 Series VPN Router Installation and Configuration Guide.

Cisco 7200 Series Routers, Cisco 7200 VXR Routers, and Cisco uBR7200 Series Routers

Following are the hardware requirements for the PA-A3 in Cisco 7200 series routers, Cisco 7200 VXR routers, and Cisco uBR7200 series routers:

The OC-3c versions of the PA-A3 port adapters are high-bandwidth and must conform to the system configuration guidelines for Cisco 7200 series routers. (Port adapters are rated by data-carrying capacity as high, medium, or low bandwidth. Cisco 7200 series routers have certain data-carrying capacity [or bandwidth] restrictions that affect the number of high-, medium-, and low-bandwidth port adapters you can install.) Refer to the Cisco 7200 Series Port Adapter Hardware Configuration Guidelines for more information on port adapter installation restrictions.

The T3 version of the PA-A3 port adapter (PA-A3-T3) is a high-bandwidth port adapter, and the E3 version of the PA-A3 port adapter (PA-A3-E3) is a medium-bandwidth port adapter. They must follow the system configuration guidelines for Cisco 7200 series routers. Refer to the Cisco 7200 Series Port Adapter Hardware Configuration Guidelines.

Your Cisco 7200 series router must have an installed NPE-150, NPE-175, NPE-200, NPE-225, or NPE-300 to support the PA-A3 port adapters. The NPE-100 does not support the PA-A3 in Cisco 7200 series routers.

Cisco 7200 series routers support up to three PA-A3 port adapters in the same chassis using an NPE-150 or NPE-200 with no Fast Ethernet interface on the I/O controller. If a Fast Ethernet interface is installed on the I/O controller, the Cisco 7200 series supports up to two PA-A3 port adapters.

To configure the number of PA-A3 port adapters supported in a Cisco 7200 VXR router using the NPE-300, refer to the Cisco 7200 Series Port Adapter Hardware Configuration Guidelines.

Your Cisco uBR7246 or Cisco uBR7223 router must have an installed NPE-150 or NPE-200 to support the PA-A3 port adapters. Your Cisco uBR7246VXR router must have an installed NPE-300 to support the PA-A3 port adapters.


Note Currently, the Cisco uBR7246VXR router supports only the PA-A3-OC3MM, PA-A3-OC3SMI, and PA-A3-OC3SML. In the future, however, the Cisco uBR7246VXR router will support both the PA-A3-E3 and PA-A3-T3.



Note PA-A3 port adapters used in the Cisco 7200 VXR routers require the correct base hardware revision to function. An error message such as the following will occur on bootup if the incorrect hardware revision is used:

PA-3-REVNOTSUPPORTED:PA in slot 1 (ATM WAN OC3 (SML)) requires base h/w revision of (2.0) for this npe cpu card



Tip The show diag command displays the hardware revision. See the "Using the show diag Command" section


The Cisco uBR7246 and Cisco uBR7246 VXR router support up to two PA-A3 port adapters and the Cisco uBR7223 router supports one PA-A3 port adapter.

All of the PA-A3 receive buffers are allocated from static random-access memory (SRAM). As a result, during bootup, if the PA-A3 cannot find enough contiguous SRAM for its use, the system stops bringing up the PA-A3 and displays an error message such as the following:

%ATMPA-3-PCIMEMNOTENOUGH: Not Enough PCI memory (0x19874) to support ATM PA on bay 5

After you replace port adapters several times using online insertion and removal (OIR), SRAM on Cisco 7200 series routers becomes fragmented. When this happens, the system might not be able to find enough contiguous SRAM to complete initialization at bootup, and you might get an error message that there is not enough memory. If you have been using the OIR feature numerous times and you get a memory error message during initialization of a PA-A3, we recommend that you power off and restart the system.

The PA-A3 and Cisco 7200 routers and Cisco uBR7200 series routers' network processor memory configurations include the following:

NPE-150 (150-MHz network processing engine) with 1 MB of SRAM and up to 128 MB of DRAM

NPE-200 (200-MHz network processing engine) with 4 MB of SRAM and up to 128 MB of DRAM

NPE-300 (262-MHz network processing engine) with 32 to 256 MB SDRAM


Note For port adapter hardware and memory configuration guidelines for Cisco 7200 series routers and for Cisco 7200 VXR routers using the NPE-300 and other Cisco 7200 series routers, refer to the Cisco 7200 Series Port Adapter Hardware Configuration Guidelines.

Refer to the Cisco IOS software release notes for the version of Cisco IOS software you are running.


Cisco 7201 Router Hardware Requirements

The PA-A3 can be installed in the single port adapter slot of the Cisco 7201 router.

Cisco 7301 Router Hardware Requirements

The PA-A3 can be installed in the single port adapter slot of the Cisco 7301 router.

Cisco 7304 PCI Port Adapter Carrier Card in Cisco 7304 Routers Hardware Requirements

One PA-A3 can be installed in the Cisco 7304 PCI Port Adapter Carrier Card. The Cisco 7304 PCI Port Adapter Carrier Card installs in Cisco 7304 router module slots 2 through 5.

Cisco 7401ASR Router Hardware Requirements

The PA-A3 can be installed in the single port adapter slot of the Cisco 7401ASR router.

VIP in Cisco 7000 Series Routers and Cisco 7500 Series Routers Hardware Requirements

Following are the hardware requirements for the PA-A3 in Cisco 7000 series routers and Cisco 7500 series routers:

The PA-A3 port adapters can be installed on the VIP2-40 and the VIP2-50 with either the Route Switch Processor 2 (RSP2) or the RSP4. The VIP2-15 does not support the PA-A3.

On a VIP2-40, you can have two PA-A3-T3 or PA-A3-E3 port adapters installed in adjacent slots or a port adapter of any other type installed in the adjacent slot with the exception of the PA-A3-OC3MM, PA-A3-OC3SMI, or PA-A3-OC3SML. You can have only one PA-A3-OC3 per VIP2-40; no other port adapter can reside in the other port adapter slot.

On a VIP2-50, VIP4-50, VIP4-80, or VIP6-80 you can have any two PA-A3 port adapters (including the PA-A3-OC3MM, PA-A3-OC3SMI, and PA-A3-OC3SML) or a port adapter of another type installed in the adjacent slot.


Note The PA-A3 port adapters are designed to provide maximum switching performance when a single port adapter is installed in a single VIP2-50. If you install two port adapters in the same VIP2-50, you might exceed the aggregate bandwidth capacity of the VIP2-50 and consequently lower the performance speeds of the port adapters.


There is no physical limit to the number of VIPs and ATM PA-A3 combinations that can be installed in the same Cisco 7500 series router, up to the total number of VIPs that the chassis supports. However, the Cisco 7500 series router backplane is finite; if you install three or more VIP and ATM PA-A3 combinations, you need be aware of the Cisco 7500 series bandwidth characteristics.

See the "Related Documentation" section for documentation related to bandwidth information.

Choose a product family or enter a specific product number to search for the minimum supported software release needed for your hardware.

75-Ohm In-Line Coaxial Attenuator

A 75-ohm in-line coaxial attenuator may be required to tune the signal between the PA-A3 and the far-end equipment, if the port adapter is experiencing line code violations (LCVs). LCVs occur when the far-end equipment transmit signal saturates the front-end receiver of the PA-A3.

Cisco offers an attenuator kit (ATTEN-KIT-PA that contains five attenuators with fixed values ranging from 3 dB to 20 dB. For more information on the attenuator kit, go to the following website:

GEM DISSE ANVISNINGER


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.

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.

Telephone Wiring Guidelines

Use the following guidelines when working with any equipment that is connected to telephone wiring or to other network cabling:

Never install telephone wiring during a lightning storm.

Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.

Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.

Use caution when installing or modifying telephone lines.

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.

Following are guidelines for preventing 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 megohms (Mohms).

Laser/LED Safety Guidelines

The single-mode transmitter in the PA-A3-OC3SMI and PA-A3-OC3SML uses a small laser to transmit the light signal to the network ring. Keep the transmit port covered whenever a cable is not connected to it. Although multimode transceivers typically use LEDs for transmission, it is good practice to keep open ports covered and avoid staring into open ports or apertures.

The single-mode aperture port contains a Class 1 laser warning label, as shown in Figure 2-1.

Warning Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do not view directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm may pose an eye hazard. Statement 1056


FCC Class A Compliance

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

Turn the television or radio antenna until the interference stops.

Move the equipment to one side or the other of the television or radio.

Move the equipment farther away from the television or radio.

Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)


Caution This product has been designed to meet these requirements. Modifications to this product that are not authorized by Cisco Systems, Inc. could void the various approvals and negate your authority to operate the product.
