To prevent system problems, do not install the PA-POS-OC3 in Cisco 7000 series routers with the Route Processor (RP) and Switch Processor (SP) or Silicon Switch Processor (SSP) installed.
Note The PA-POS-OC3 is considered a high-bandwidth port adapter. Traffic from multiple PA-POS OC3 network interfaces could theoretically exceed the bandwidth of the CxBus or CyBus. This would cause packets to be dropped. There is no physical limit to the number of PA-POS-OC3s that you can install in a Cisco 7000 series or Cisco 7500 series router; however, because of the theoretical bandwidth limit of the CxBus and Cybus, the practical limit is two PA-POS-OC3s in Cisco 7000 series routers and four PA-POS-OC3s in Cisco 7500 series routers.
For Cisco 7200 series routers, you can install up to three PA-POS OC3s in a system without a Fast Ethernet interface on the input/output (I/O) controller, and you can install up to two PA-POS OC3s in a system with a Fast Ethernet interface on the I/O controller. Further, the PA-POS-OC3 requires one of the following Network Processing Engine (NPE) models to operate:
•NPE-150 (150-MHz network processor)—up to 128 MB of DRAM
•NPE-175 (200-MHz network processor)—up to 128 MB of DRAM
•NPE-200 (200-MHz network processor)—up to 128 MB of DRAM
•NPE-225 (262-MHz network processor)—up to 128 MB of DRAM
•NPE-300 (262-MHz network processor)—up to 128 MB of DRAM
For Cisco uBR7200 series routers, you can install up to two PA-POS OC-3s in a Cisco uBR7200 series, and one PA-POS-OC3 in a Cisco uBR7223.
For all systems in which you install the PA-POS-OC3, use the show version command to display the current configuration of the router or switch, including the system software version that is currently loaded and running. Use the show diag slot command to view specific information about the hardware installed in your system.
Checking Hardware and Software Compatibility
To check the minimum software requirements of Cisco IOS software with the hardware installed on your router, Cisco maintains the Software Advisor tool on Cisco.com. This tool does not verify whether modules within a system are compatible, but it does provide the minimum IOS requirements for individual hardware modules or components.
Note Access to this tool is limited to users with Cisco.com login accounts.
To access Cisco Software Advisor, go to the following URL: http://www.cisco.com/pcgi-bin/Support/CompNav/Index.pl
Choose a product family or enter a specific product number to search for the minimum supported software release needed for your hardware.

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 if 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 consist of 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.
For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohm (Mohm).
Laser and LED Safety
The single-mode aperture port contains a Class 1 laser warning label, as shown in Figure 2-1.
Figure 2-1 Class 1 Laser Warning Label on PA-POS-OC3SMI and PA-POS-OC3SML
Warning Because invisible laser radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to laser radiation and do not stare into open apertures.
Warning Class 1 laser product.
The multimode aperture port contains a Class 1 LED warning label, as shown in Figure 2-2.
Figure 2-2 Class 1 LED Warning Label on PA-POS-OC3MM
Warning Because invisible radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to radiation and do not stare into open apertures.
Warning Class 1 LED product.
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.)
Note The PA-POS-OC3 port adapter 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.
