Important Information
Starting in IOS Release 12.0(27)S, you can increase the memory in the Cisco 10720 Internet Router from 256 MB to 512 MB. Cisco IOS software running on a Cisco 10720 Internet Router in which 512 MB of Route Processor (RP) memory has been installed can then use up to 512 MB of memory.
The upgrade procedures must be completed in the order specified in this document. See the "Upgrading and Verifying the Route Processor Memory" section for information on the order in which the procedures must be completed.
Overview
The RP memory of the Cisco 10720 Internet Router is Dynamic Random Access Memory (DRAM) that enables an onboard Route Processor to perform several tasks for Cisco 10720 Series Internet Routers, including:
•
Running the Cisco IOS software image
•Storing and maintaining the network routing tables
You can physically upgrade the RP memory from the factory default of 256 MB to the maximum physical configuration of 512 MB.
The RP memory upgrade supports increasingly larger route tables and allows for more route table entries.
Figure 1 shows the location of the RP memory socket on the chassis.
Note The 512-MB upgrade is supported in IOS Release 12.0(27)S. If you have 512 MB of RP memory installed in the Cisco 10720 Internet Router but do not have the IOS Release 12.0(27)S or later running, the router will use only 256 MB.
Note A Cisco 10720 Internet Router with 256 MB of RP memory only supports up to 256 MB of memory for IOS use, even when running IOS Release 12.0(27)S and later releases.
To verify the amount of memory on a Cisco 10720 Internet Router available for IOS use, use the show version command. See the "Hardware and Software Requirements" section for more information.

Safety Warnings
Before upgrading the RP memory, note the following safety warnings:
Caution This router is equipped with a redundant power supply. Ensure both power supply connections are disconnected before beginning any procedure.
Warning Read the installation instructions before you connect the system to its power source.
Warning Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord.
Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.
For more safety information about your Cisco 10720 Internet Router, refer to the Regulatory Compliance and Safety Information for the Cisco 10720 Internet Router document that shipped with your router.
Disconnect Device Warnings
The Cisco 10720 Internet Router power source must be disconnected before performing any task on the router. Please refer to the safety warnings in the "Powering Down the Router" section of Chapter 5, "Maintaining the Cisco 10720 Internet Router", in the Cisco 10720 Internet Router Installation and Configuration Guide.
Electrostatic Discharge
Electrostatic discharge (ESD) can damage circuit boards and other electronic equipment if they are handled improperly, resulting in complete or intermittent failures. Cisco recommends using an ESD-preventive strap when you handle a router or one of its components. Electromagnetic interference (EMI) shielding is an integral component of the router.
Caution For safety, periodically check the resistance value of the ESD-preventive wrist strap. The resistance measurement should be between 1 and 10 megohms.
Preventing Electrostatic Discharge
When handling router components, observe the following guidelines to prevent ESD damage:
•Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact. If using an ESD-preventative wrist strap, connect the equipment end of the connection cord to bare metal on the router chassis. (See Figure 2.)
•Avoid touching the board or connector pins.
•Place a removed component on an antistatic surface on in a static shielding bag. If you plan to return the component to the factory, immediately place it in a static shielding bag.
•Avoid contact between the component and clothing. The wrist strap protects the component only from ESD voltages on the body; ESD voltages on clothing can still cause damage.

Note Leave a small service loop in the ground lead to ensure that the ground lead is the last lead to disconnect from the power supply. If a great deal of strain is placed on the ground, +48V, and -48V DC-input leads, it is important that the ground power lead is the last to disconnect from the power supply terminal.
Note Allow sufficient slack in the power cable leads for strain relief. The power cable leads should be adequately secured to prevent the power supply terminal connections from being subjected to strain.
Step 7 After wiring the DC power supply, remove the tape from the circuit breaker switch handle and reinstate power by moving the handle of the circuit breaker to the on position.
Installing the Cable Management Cover (Optional)
Perform the following steps to install the cable-management system:
Step 1 Attach an ESD-preventive wrist strap to your wrist, and to the router or to a bare metal surface. (See the "Preventing Electrostatic Discharge" section.)
Step 2 (Optional) Using a Number 1 Phillips screwdriver, attach the cable-management cover with four screws to secure the cable-management cover to the router. (See Figure 30.)

Checking the 512-MB Route Processor Installation
When you power up the router, the router reinitializes and detects the memory change as part of the reinitialization cycle. The time required for the router to initialize can vary with different router configurations and memory configurations.
If the router does not initialize properly after you replace the memory, or if the console terminal displays a checksum or memory error, verify that you have installed the correct RP memory and that it is installed correctly in the router.
If the router fails to restart properly after several attempts and you are unable to resolve the problem, access Cisco.com or contact your Cisco service representative for assistance. Before calling, make note of any console error messages, unusual LED states, or other router indications or behaviors that might help to resolve the problem. Under certain highly improbable scenarios (for example, battery failure), the router may fail to boot after the 512-MB upgrade. In such cases, see the "Obtaining Technical Assistance" section for information on contacting Cisco.
To check the installation of the RP memory, use the show version command and check that the upgraded RP memory is 512 MB.
See the following show version command example to locate the RP memory. Line 17 of the example is in italic print to indicate where the RP memory is listed.

Electromagnetic Compatibility Regulatory Statements
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.
Modifying the equipment without Cisco's authorization may result in the equipment no longer complying with FCC requirements for Class A digital devices. In that event, your right to use the equipment may be limited by FCC regulation and you may be required to correct any interference to radio or television communication at your 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. (In other words, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Site Wiring Distance and Interference Guidelines
This section offers site wiring guidelines for setting up the site plant wiring and cabling. When planning the location of the new system, consider the information in the following sections:
•Electromagnetic Interference
•Distance Limitations for Signaling and Unshielded Conductors
Electromagnetic Interference
Electromagnetic interference can occur between the field and the signals on the wires when the wires are run for any significant distance. This fact has two implications for the construction of plant wiring:
•Poor wiring practice can result in radio interference emanating from the plant wiring.
•Strong EMI, especially when it is caused by lightning or radio transmitters, can destroy and/or cause interference with the signal drivers and receivers in the Cisco 10720 Internet Router, and can create an electrical hazard by conducting power surges through lines and into equipment.
Note To predict and remedy strong EMI, consult experts in radio frequency interference (RFI).
A good quality twisted pair cable or shielded twisted pair cable helps limit radiation and noise induced into the cable, minimizing the following problems:
•Potential for radio interference
•Potential for interference with the data transmission
Distance Limitations for Signaling and Unshielded Conductors
Give special consideration to the effect of a lightning strike in the site vicinity if wires exceed recommended distances, or if wires pass between buildings. The electromagnetic pulse (EMP) caused by lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic devices.
Provide a properly grounded and shielded environment. Consider electrical surge suppression issues by addressing the following items:
•Potential surge sources
•Distance
Caution Splicing can degrade cable performance.
