The PA-A6 port adapters are high-bandwidth and must conform to the system configuration guidelines for Cisco 7200 series routers and Cisco 7200 VXR routers. (Port adapters are rated by data-carrying capacity as high, medium, or low bandwidth. Cisco 7200 series routers and Cisco 7200 VXR routers have certain data-carrying capacity [or bandwidth] restrictions that affect the number of high-bandwidth, medium-bandwidth, and low-bandwidth port adapters you can install.) For more information on port adapter installation restrictions, refer to the Cisco 7200 Series Port Adapter Hardware Configuration Guidelines at the following URL:
Your Cisco 7200 series router or Cisco 7200 VXR router must have an installed NPE-400 or NSE-1. Table 2-1 shows the minimum SDRAM needed to support the PA-A6.

A 75-ohm in-line coaxial attenuator may be required to tune the signal between the port adapter
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-A6.
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, refer to Installing the 75-Ohm In-Line Coaxial Attenuator on Cisco Port Adapters at the following URL:
This section provides safety guidelines that you should follow when working with any equipment that connects to electrical power or telephone wiring.
Safety warnings appear throughout this publication in procedures that, if performed incorrectly, might harm you. A warning symbol precedes each warning statement.
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.
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.
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.
The single-mode transmitter in the PA-A6 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 disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051

The multimode aperture contains a Class 1 LED warning label, as shown in Figure 2-2.

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.)
