THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

The following information is for FCC compliance of Class A devices: 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.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications 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. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

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.

Obtaining Technical Assistance

78-13342-03

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.

This section describes the types of memory stored in the router and tells how to find out how much of each type the router has.

For instructions on how to upgrade memory in the router, See Appendix C,

“Installing and Upgrading Memory and Packet Voice Data Modules,” in this

guide.

Types of Memory

The router has the following types of memory:

• Dynamic RAM (DRAM)—This is the main storage memory for the router.

DRAM is also called working storage and contains the dynamic configuration information. The router stores a working copy of Cisco IOS software, dynamic configuration information, and routing table information in DRAM.

• Nonvolatile RAM (NVRAM)—This type of memory contains the startup

configuration.

78-13342-03

Cisco 1760 Modular Access Router Hardware Installation Guide

Router Memory

• Flash memory—This special kind of erasable, programmable memory

contains a copy of the Cisco IOS software. The Flash memory structure can store multiple copies of the Cisco IOS software. You can load a new level of the operating system in every router in your network; then, when it is convenient, you can upgrade the whole network to the new level.

Amounts of Memory

The Cisco 1760 is shipped with 64 MB of DRAM and 32 MB of Flash memory on board.

The Cisco 1760-V is shipped with 96 MB of DRAM (64 MB on board and 32 MB in a DIMM socket) and 32 MB of Flash memory (32 MB on board and one empty SIMM socket).

Use the show version command to view the amount of DRAM, NVRAM, and Flash memory stored in your router. The following example shows the output of the show version command.

With this process, you determine the configuration of the router, so that you may restore the configuration after the password is recovered.

• Resetting the Router

With this process, you reconfigure the router to its intial startup configuration. You then display the enable password, if one is used.

• Resetting the Password

If you are using an enable secret password, you enter a new password with this process. You then restore the router to its prior configuration.

• Resetting the Configuration Register Value

If you are using an enable password, you use this process to restore the router to its prior configuration.

Chapter 3 Troubleshooting

Note See the “Hot Tips” section on Cisco.com for additional information on replacing

enable secret passwords.

Determining the Configuration Register Value

Follow these steps to determine the configuration register value:

Step 1 Connect an ASCII terminal or a PC running a terminal-emulation program to the

console port on the router. See the “Connecting a PC” section in Chapter 2, “Installation.”

Step 2 Configure the terminal to operate at 9600 baud, 8 data bits, no parity, 1 stop bit

and no flow control.

Step 3 Reboot the router by pressing the power switch to the off ( 0 ) position and then

to the on ( | ) position.

Problem-Solving

The key to problem-solving is to isolate the problem to a specific subsystem by comparing what the router is doing to what it should be doing.

When problem-solving, consider the following subsystems of the router:

• WICs and VICs—Observe the LEDs on the cards and the LEDs on the router

front panel to help identify a failure. For more information on WICs and VICs, refer to the Cisco WAN Interface Cards Hardware Installation Guide that comes with each card.

• Cables—Check all the external cables that connect the router to the network.

Problem-Solving

• Power system—Check the external power source, power cable, router power

supply, and circuit breaker. Check for inadequate ventilation or air circulation that might cause overheating.

• ISDN configuration—Consider ISDN-specific hardware and software

configurations (ISDN BRI WICs only).

OK LED Diagnostics

Use the OK LED to help determine any problems with the router. When the router first boots up, it performs a power-on self-test (POST). If the router detects a problem during the POST, the OK LED blinks in a different pattern (described in

Table 3-1), depending on the problem. A pattern is a specific number of blinks

that is repeated until the router is turned off. If the router experiences any of these problems, contact your Cisco reseller.

Installing a PVDM

You can install up to two PVDMs to support enhanced versions of digital signal processors (DSPs).

There are five types of PVDMs:

• PVDM-256K-4—Supports one DSP

• PVDM-256K-8—Supports up to two DSPs

• PVDM-256K-12—Supports up to three DSPs

• PVDM-256K-16—Supports up the four DSPs

• PVDM-256K-20—Supports up to five DSPs

Each DSP supports two analog voice ports or one ISDN BRI port. Each analog VIC used with the Cisco 1760 router has two voice ports and requires a single DSP. The 2-port ISDN Voice-BRI requires two DSPs. Table C-1 shows the possible combinations of PVDMs and voice ports for the Cisco 1760 router.

The Cisco 1760 router has two PVDM slots. Any of the PVDMs can occupy either slot. The total number of DSPs provided by one or two PVDMs installed in those slots must be greater than or equal to the number of DSPs required by the number and type of VICs installed, as described in Table C-1.

For example, if you have one PVDM (a single DSP), and you want to increase the number of DSPs to 3, you can either add a PVDM-256K-8 in the second slot or replace the PVDM-256K-4 with a PVDM-256K-12.

Follow these steps to install a PVDM on the router motherboard.

Warning

Step 1 Locate the PVDM slots on the motherboard. (See Figure C-3.) Step 2 Remove any existing PVDM modules by pulling the PVDM snaps away from the

Preventing Electrostatic Discharge Damage

Before installing a VPN module, read the electrostatic discharge (ESD) instructions in this section. ESD is a discharge of stored static electricity that can damage equipment and impair electrical circuitry. It occurs when electronic components are improperly handled and can result in complete or intermittent failures.

The following are guidelines for preventing ESD damage:

• Before opening the chassis, turn the router power switch to off ( O ).

• Disconnect the power cable to the router.

• Always use an ESD-preventive wrist or ankle strap, and ensure that it makes

good skin contact.

• Avoid contact between equipment and clothing. The wrist or ankle strap

protects the equipment only from ESD voltages on the body; ESD voltages on clothing can still cause damage.

78-13342-03

• Handle printed circuit cards by the edges only. Avoid touching the

components, traces, or any connector pins.

• Place a removed card component on an antistatic surface or in a static

shielding bag.

• Do not remove the wrist or ankle strap until after you complete the

installation.
