Safety with Electricity

When working on equipment that is powered by electricity, follow these guidelines:

•Locate the emergency power-off switch in the room in which you are working. Then, if an electrical accident occurs, you can quickly shut off the power.

•Before working on the router, turn off the power and unplug the power cord.

•Disconnect all power before doing the following:

–Installing or removing a router chassis

–Working near power supplies

•Do not work alone if potentially hazardous conditions exist.

•Never assume that power is disconnected from a circuit. Always check.

•Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, and missing safety grounds.

If an electrical accident occurs, proceed as follows:

•Use caution; do not become a victim yourself.

•Turn off power to the router.

•If possible, send another person to get medical aid. Otherwise, determine the condition of the victim and then call for help.

•Determine if the victim needs rescue breathing or external cardiac compressions; then take appropriate action.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD can occur when printed circuit cards are improperly handled and can result in complete or intermittent failures. Always follow ESD prevention procedures when removing and replacing cards. Ensure that the router chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis frame to safely channel unwanted ESD voltages to ground. To guard against ESD damage and shocks, the wrist strap and cord must be used properly. If no wrist strap is available, ground yourself by touching the metal part of the chassis.

Caution For safety, periodically check the resistance value of the ESD-preventive wrist strap, which should be between 1 and 10 megohms (Mohms).

Required Tools and Equipment

To install an AIM in a chassis, you need the following tools and equipment:

•Cisco AIM, supplied with standoffs, two screws, and adhesive label

•Number 2 Phillips screwdriver or flat-blade screwdriver

•1/4-inch nut driver

•Torx-15 screwdriver (for installation in Cisco 3660 only)

•3/16-inch open-end wrench (optional)

•ESD-preventive wrist strap

Configuring Internet Encryption Using Encryption AIMs

There are no configuration commands specific to the encryption hardware. Both software-based and hardware-based encryption are configured in the same way. The system automatically detects the presence of an encryption module at bootup and uses it to encrypt data; if no encryption hardware is detected, software is used to encrypt data.

To disable the VPN encryption module and revert to software encryption, enter the no crypto engine accel [0 | 1] command. To reenable the VPN encryption module, enter the crypto engine accel [0 | 1] command.

Whenever you install a new interface, or if you want to change the configuration of an existing interface, you must configure the interface. If you replace a module that was already configured, the router recognizes it and brings up the interface in the existing configuration.

For information about configuring Internet encryption, including the Internet Key Exchange (IKE) security protocol and IPSec network security, see the "IP Security and Encryption" part of the Cisco IOS Security Configuration Guide, Release 12.3 at the following URL:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123cgcr/sec_vcg.htm

For complete information about global configuration commands and about configuring LAN and WAN interfaces on your router, see the Cisco IOS configuration guides and command references.

Configuring Voice and ATM AIMs

For information about configuring ATM and voice processing on Cisco 2600 series and Cisco 3660 routers using AIM-ATM, AIM-VOICE-30, and AIM-ATM-VOICE-30 advanced integration modules, see the AIM-ATM, AIM-VOICE-30, and AIM-ATM-VOICE-30 on the Cisco 2600 Series and Cisco 3660 feature module on Cisco.com at the following URL:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122limit/122x/122xb/122xb_2/ft_gins2.htm

For complete information about global configuration commands, and about configuring ATM on your router, see the Cisco IOS configuration guides and command references.

Configuring Data Compression AIMs

There are no configuration commands specific to the compression hardware. Both software-based and hardware-based compression are configured in the same way. The system automatically detects the presence of a data compression module at startup and uses it to compress data; if no compression hardware is detected, software is used to compress data.

Note Before you use an AIM-COMPR-2 data compression AIM, see the "Upgrading a PLD on Cisco 2600 Series Routers" section below to determine if you need to upgrade the programmable logic device (PLD).

For information about displaying statistics and about enabling and disabling data compression AIMs on specific interfaces, see the "Data Compression AIM Commands" section.

For complete information about global configuration commands, and about configuring data compression on your router, see the Cisco IOS configuration guides and command references for your Cisco IOS release.

Upgrading a PLD on Cisco 2600 Series Routers

Perform the following procedure to determine whether your Cisco 2600 series router (Cisco 2691 excepted) requires a programmable logic device (PLD) upgrade, and to do the PLD upgrade, if required.

Note You must perform this procedure before you enter any data compression AIM commands.

Step 1 In privileged EXEC mode, enter the upgrade pld command: 

Router# upgrade pld

You will see one of the following four messages: 

Message 1 No upgrade is required. Router#


If you see Message 1, your router does not require a PLD upgrade. Your data compression 
AIM is ready for use. See the "Data Compression AIM Commands" section for information 
about displaying statistics and about enabling and disabling data compression AIMs on 
specific interfaces.

Message 2

A PLD is required but not available on this IOS release.

Router#


If you see Message 2, your router requires a PLD upgrade, but you must also install a 
Cisco IOS software release that supports PLD upgrade. Load any appropriate c2600 release 
from Cisco IOS Release 12.0, 12.1, or 12.2. After you install the new Cisco IOS software, 
begin again with Step 1.

Message 3

All WAN interface cards (WICs) must be removed during this procedure.

Please power off the system, remove all WICs and issue this command again. When the 
procedure completes, power off the system and re-install all WIC cards into their 
respective slots before continuing.

Router#

If you see Message 3, your router requires a PLD upgrade, but you must first remove all WAN interface cards (WICs) that are installed in your router. After removing all WAN interface cards, begin again with Step 1. 

Message 4

PLD UPGRADE PROCEDURE. READ THESE INSTRUCTIONS CAREFULLY.

This procedure will reload the hardware Programmable Logic Device (PLD). All network 
activity will be stopped and the router will automatically reload upon completion. You 
should only execute this command if you were explicitly instructed to do so. If the 
upgrade command is issued through a remote telnet session, there will be no confirmation 
on completion of the procedure, but the router will still reload normally.


Note that the upgrade procedure may take up to 15 seconds to complete.



During the upgrade, the router must not be interrupted.


DO NOT POWER OFF THE SYSTEM DURING THE OPERATION!

DOING SO MAY LEAVE THE HARDWARE IN AN INOPERABLE STATE!


Proceed with PLD upgrade? [yes/no]:

If you see Message 4, your router is ready for you to perform the PLD upgrade. Enter y to continue with the upgrade procedure, or enter n to stop.

Step 2 When the upgrade procedure is finished, verify that the following message appears: 

The upgrade procedure was successful. The PLD has been safely updated. The system will 
automatically reload.

Step 3 After the PLD upgrade procedure is completed and the system has reloaded, power down the router, and reinstall the WICs in their respective slots.

Your router is now ready to power up. For information about displaying statistics and about enabling and disabling data compression AIMs on specific interfaces, see the next section, "Data Compression AIM Commands".

Data Compression AIM Commands

The following sections describe commands for displaying data compression statistics and for enabling and disabling data compression AIMs on specific interfaces.

Displaying Statistics

Use the show pas caim stats aim-slot command to display statistics describing the operation of the data compression AIM.

The command in the following example displays statistics for an AIM located in AIM slot 0 of a

PPP Interface Configuration

The existing compression implementation for Point-to-Point Protocol (PPP) interfaces allows you to specify compression using the following commands in interface configuration mode. For more information on these commands, see the Cisco IOS configuration guides and command references for your Cisco IOS release.

•no compress—Turns off compression for the interface.

•compress stac—Enables compression for the interface. Uses hardware compression if available; otherwise, uses software compression.

•compress stac software—Enables compression for the interface. Uses software compression only.

•compress stac caim caim element #—Enables compression for the interface. Uses the specified data compression AIM.

•compress mppc—Enables compression for the interface. Uses software compression only.

Frame Relay Stac Configuration

Use the following Frame Relay interface commands to configure Stac compression on a per-Frame-Relay-port basis. For more information on these commands, see the Cisco IOS configuration guides and command references for your Cisco IOS release.

•no frame-relay payload-compression—Turns off compression for this port.

•frame-relay payload-compression frf9 stac—Enables compression for this port. Uses hardware compression if available; otherwise, uses software compression.

•frame-relay payload-compression frf9 stac software—Enables compression for this port. Uses software compression only.

•frame-relay payload-compression frf9 stac caim caim element #—Enables compression for this port. Uses the specified data compression AIM.

Use the following Frame Relay map commands to configure compression on a per data-link connection identifier (DLCI) basis. For more information on data compression AIM commands, see the Cisco IOS configuration guides and command references for your Cisco IOS release.

•frame-relay map protocol protocol-address dlci payload-compression frf9 stac—Enables compression for this data-link connection (DLC). Uses hardware compression if available; otherwise, uses software compression.

•frame-relay map protocol protocol-address dlci payload-compression frf9 stac software—Enables compression for this DLC. Uses software compression only.

•frame-relay map protocol protocol-address dlci payload-compression frf9 stac caim caim element #—Enables compression for this DLC. Uses the specified data compression AIM.

Locate the serial number label on your product and record the information before placing a service call.

Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:

http://www.cisco.com/techsupport/servicerequest

For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
