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 inform ation 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.

Obtaining Technical Assistance

Reporting Security Problems in Cisco Products

Cisco is committed to delivering secure products. We test our products internally before we release them, and we strive to correct all vulnerabilities quickly. If you think that you have identified a vulnerability in a Cisco product, contact PSIRT:

• For Emergencies only— security-alert@cisco.com

An emergency is either a condition in which a system is under active attack or a condition for which a severe and urgent security vulnerability should be reported. All other conditions are considered nonemergencies.

• For Nonemergencies— psirt@cisco.com

In an emergency, you can also reach PSIRT by telephone:

• 1 877 228-7302

• 1 408 525-6532

Tip We encourage you to use Pretty Good Privacy (PGP) or a compatible product (for example, GnuPG) to

encrypt any sensitive information that you send to Cisco. PSIRT can work with information that has been encrypted with PGP versions 2.x through 9.x.

Never use a revoked or an expired encryption key. The correct public key to use in your correspondence with PSIRT is the one linked in the Contact Summary section of the Security Vulnerability Policy page at this URL:

http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html

The link on this page has the current PGP key ID in use.

If you do not have or use PGP, contact PSIRT at the aforementioned e-mail addresses or phone numbers before sending any sensitive material to find other means of encrypting the data.

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 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 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 USA: 1 800 553-2447

For a complete list of Cisco TAC contacts, go to this URL:

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

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)—An existing 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 operations 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.

Chapter 1 Overview and Specifications

DPT Uplink Card Faceplate and Specifications

The Cisco 10720 Internet Router provides network access using Ethernet and optional Dynamic Packet Transport (DPT), Packet over SONET (POS), or IEEE 802.17 RPR technology for optical connectivity. Each router is equipped with one uplink card located in the upper card slot. The OC-48 RPR/SRP, OC-48/STM-16c DPT, and POS/DPT uplink cards are equipped with dual OC-48c/STM-16c optical uplink network ports with an aggregate bandwidth of 5 Gbps. The console/auxiliary card provides console and serial (AUX) ports only.

Although the console/auxiliary card does not provide uplink capabilities, it is described here because it is installed the same as the DPT and POS/DPT uplink cards. You can use the Cisco 10720 Internet Router console/auxiliary card with either a 24-Port 10/100 Ethernet TX access card or a Combined 4-Port Gigabit Ethernet 8-Port 10/100 Ethernet TX access card to customize the Cisco 10720 Internet Router as an Ethernet-only router.

For DPT and POS/DPT uplink cards, the cable connector is LC fiber-optic connector. For the RPR/SRP uplink card, the fiber-optic cable connects to an LC connector in a small form-factor pluggable (SFP) optical connector. When connecting to DPT networks, the left port is the Spatial Reuse Protocol (SRP) side A, and the right port is side B. (See Figure 1-1.) When connecting to POS networks, there are two individual ports. Each port consists of transmit (TX) and receive (RX). (See Figure 1-2.) When connecting to DPT networks in Resilient Pack Rings (IEEE 802.17 RPR) mode, the left port is span West, and the right port is span East. When in the Spatial Reuse Protocol (SRP) mode, the left port is side A, and the right port is side B. (See Figure 1-3.)

For information and instructions on connecting the optical cables to the DPT uplink card or to the RPR/SRP uplink card and for setting up four-node rings, see Chapter 1, “Overview and Specifications” and Chapter 4, “Creating a Four-Node Ring Using the Uplink Cards.”

Preventing Electrostatic Discharge

Electrostatic discharge (ESD) damage can occur when electronic cards or components are improperly handled. This will cause complete or intermittent failures. We recommend 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.

Page 31

2-5

Book Title

78-13113-06 B0

Chapter 2 Preparing for Installation

Safety and Compliance

Following are guidelines for preventing ESD damage:

• Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact.

Connect the equipment end of the connection cord to bare metal on the router chassis. (See

Figure 2-1.)

• Attach an ESD-preventive wrist strap to your wrist, and to the chassis or to a bare metal surface.

(See Figure 2-1.)

• The wrist strap protects equipment from ESD voltages on the body only; ESD voltages on clothing

can still cause damage to electronic components.

Caution To avoid ESD damage to the equipment, periodically check the resistance value of the

ESD-preventive wrist strap. The resistance measurement should be between 1 and 10 megohms (Mohms).

Figure 2-1 Attaching an ESD-Preventive Strap

•

When installing the card, confirm that the card is fully seated in the midplane and tighten the spring-loaded screws. These screws prevent accidental removal, provide proper grounding for the system, and help ensure that the connectors are seated in the midplane. (See Figure 2-1 and the

“Figure 3-6Disconnecting the Optical Interface Cable” section on page 3-6.)

• When removing the card, use the spring-loaded screws to unseat the card connector from the

midplane. (See Figure 3-10 and the “Figure 3-6Disconnecting the Optical Interface Cable” section

on page 3-6.)

• Handle the card by the spring-loaded screws only; avoid touching the board or connector pins.

• Place the card board-side-up on an antistatic surface or in a static shielding bag. If you plan to return

the card to the factory, immediately place it in a static shielding bag.

• Avoid contact between the card and clothing. The wrist strap protects the board only from ESD

voltages on the body; ESD voltages on clothing can still cause damage.

SONET Distance Information for RPR/SRP, DPT, and POS/DPT Uplink Cards

The maximum distance for single-mode installations is determined by the amount of light loss in the fiber path. Good quality single-mode, short-reach fiber with very few splices can carry an uplink card signal two kilometers.

If your environment requires the signal to travel close to the typical maximum distance (see Chapter 1,

“Overview and Specifications”), use an optical time domain reflectometer (OTDR) to measure the power

loss.

Figure 3-13 Simplex Optical Cable

Figure 3-14 Duplex Optical Cable

For SONET/SDH single-mode fiber-optic connections, use one duplex LC small form-factor pluggable(SFP) optical cable (see Figure 3-14) or two simplex optical cables (See Figure 3-13.)

Caution Splicing can degrade cable performance.

Note Single-mode fiber-optic cables are available from various vendors. These cables are not available

from Cisco Systems.

Chapter 3 Installing and Removing the Uplink Cards

Installing the Cable-Management System

The cable-management system, located on the front of the router, organizes the interface cables. To keep the cables free of sharp bends, extend the cables from the center out both sides of the cable-management system. Excessive bending of an interface cable can degrade performance and possibly harm the cable.

Perform the following steps to install the cable-management system:

Step 1 Power down your router. (See the “Powering Down the Router” section on page 3-2.)

Step 2 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 on page 2-4.)

Figure 3-19 Attaching Cable-Management Tray

Step 3

Attach the cable-management tray to the router using four of the 3.5-mm x 6-mm screws that are shipped with the router. Secure the tray with two screws on each side of the router chassis using a Number 1 Phillips screwdriver. (See Figure 3-19.)

Figure 3-20 Managing Router Cables with the Cable-Management Tray

Step 4 Separate cables and lead them out the sides of the cable-management tray. Use a cable tie to keep the

cables together. (See Figure 3-20.)

Caution To avoid damage to the cables, avoid excessive bending.

Troubleshooting the POS Uplink Card Installation

• STS Path Loss-of-Pointer (LOP)

• STS Path Alarm Indication Signal (AIS)

• STS Path Remote Defect Indication (RDI)

• B1 Bit Error Rate (BER) threshold crossing alarm (b1-tca)

• B2 BER threshold crossing alarm (b2-tca)

• B3 BER threshold crossing alarm (b3-tca)

• Line Bit Interleave Parity (LBIP) BER in excess of signal degrade threshold (sd-ber)

• LBIP BER in excess of signal failure threshold (sf-ber)

At any time the status of the SONET/SDH alarm and signal events can be examined using the show controllers command, as shown in the following example:

Router# show controllers pos1/1 Interface POS1/1 Hardware is OC48 POS SECTION LOF = 0 LOS = 0 BIP(B1) = 0 LINE AIS = 0 RDI = 0 FEBE = 0 BIP(B2) = 0 PATH AIS = 0 RDI = 0 FEBE = 0 BIP(B3) = 0 LOP = 0 NEWPTR = 0 PSE = 0 NSE = 0

Active Defects: None Active Alarms: None Alarm reporting enabled for: SF SLOS SLOF B1-TCA B2-TCA PLOP B3-TCA

Framing: SONET APS

COAPS = 0 PSBF = 0 State: PSBF_state = FALSE ais_shut = FALSE Rx(K1/K2): 00/00 S1S0 = 00, C2 = CF Remote aps status non-aps; Reflected local aps status non-aps CLOCK RECOVERY RDOOL = 0 State: RDOOL_state = FALSE PATH TRACE BUFFER : STABLE Remote hostname : RouterB Remote interface: POS1/0 Remote IP addr : 2.2.2.1 Remote Rx(K1/K2): 00/00 Tx(K1/K2): 00/00

BER thresholds: SF = 10e-4 SD = 10e-6 TCA thresholds: B1 = 10e-6 B2 = 10e-6 B3 = 10e-6

OPTICS RX readout values: -6 dBm

Loopback Testing

The POS uplink card supports two loopback modes for network testing, fault isolation, and agency compliance. The uplink card loopback modes are:

Internal loopback mode—Packets sent from the Cisco 10720 Internet Router out of the uplink card POS port TX optics are also looped back into the Cisco 10720 Internet Router.

Line loopback mode—Packets received by the POS uplink card port RX optics and sent into the Cisco 10720 Internet Router are also looped back out of the uplink card port TX optics.

Loopback testing is enabled through software. See the Cisco IOS Software Configuration for the

Cisco 10720 Internet Router.

Additional Troubleshooting Resources

For more troubleshooting information for the uplink card, refer to the following publications:

• Chapter 4, “Troubleshooting”, in the Cisco 10720 Internet Router Installation and Configuration

Guide

• Cisco IOS Software Configuration for the Cisco 10720 Internet Router document

Cleaning the Fiber-Optic Connections

For information about cleaning fiber-optic cable connectors and receptacles, see the Inspection and

Cleaning Procedures for Fiber-Optic Connections document. It provides detailed illustrations and photos of

procedures and equipment required to properly clean fiber-optic connections.
