Cisco uBR10-LCP2-MC28C Overview

The Cisco uBR10-LCP2-MC28C cable interface line card is a combination of two components:

Cisco uBR-MC28C—Provides two downstream and eight upstream ports, divided into two domains.

Cisco Line Card Processor (Cisco uBR10-LCP2) adapter card—Provides the mechanical and electrical conversions necessary for the Cisco uBR-MC28C cable interface line card to fit the form factor used in the Cisco uBR10012 chassis.


Note All installation information about the LCP adapter card also applies to the LCP2 adapter card.



Note You must be using revision 07 of the LCP adapter card or any version of the LCP-2 card to support N+1 requirements when the card is used as a redundant or protect card. See the Proactive Upgrade Field Notice number 18301 at the following URL:

http://www-tac.cisco.com/Support_Library/field_alerts/fn18103.htm
l.


The Cisco uBR10-LCP2 adapter card and Cisco uBR-MC28C cable interface line card are mechanically connected to each other using brackets and power connectors. The two cards are inserted into and removed as a single logical and physical unit.

The Cisco uBR10-LCP2 adapts the Cisco uBR-MC28C cable interface line card to the form factor of the Cisco uBR10012 chassis and provides:

Proper voltage conversion for the card and chassis

Boot code required to use the Cisco uBR-MC28C cable interface line card

SDRAM for buffering packets as they are transferred between the card and PRE1 (or PRE)

The Cisco uBR10-LCP2-MC28C cable interface line card supports Online Insertion and Removal (OIR). OIR uses the MAC address assigned to the Cisco uBR10-LCP2, allowing you to replace a Cisco uBR-MC28C on a Cisco uBR10-LCP2 adapter card without losing any configuration information.


Note Do not attempt to separate or remove the Cisco uBR-MC28C cable interface line card from the Cisco uBR10-LCP2 adapter card while it is inserted in the Cisco uBR10012 chassis. Remove the card from the chassis as a unit and then separate them on a lab bench or other area that protects against ESD damage.

Safety Information and Warnings

Following are safety guidelines that you should follow when working with any equipment that connects to electrical power.

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 when 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.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which occurs when electronic cards or components are improperly handled, can result in complete or intermittent failures. The AC-input power shelf and its AC power modules contain a printed circuit card that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the cards from ESD, use an antistatic strap each time you handle the modules.

Following are guidelines for preventing ESD damage:

Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact. Before removing a card from the chassis, connect the equipment end of the strap to a bare metal, unpainted surface on the chassis or rack-mount.

Handle components by the carrier edges only; avoid touching the card components or any connector pins.

When removing a module, place it on an antistatic surface or in a static-shielding bag. If the module will be returned to the factory, immediately place it in a static-shielding bag.

Avoid contact between the modules and clothing. The wrist strap protects the card from ESD voltages on the body only; ESD voltages on clothing can still cause damage.


Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms.

If yes, the system is operational.

Step 2 Are any enabled LEDs off?

a. If the enabled LED on a cable interface line card is off, first verify that the card has been enabled and configured for operations. The enabled LED remains off when a card has not been configured and enabled.

b. If a port has been enabled but its corresponding enabled LED is still off, check to see if the cable interface line card has pulled away from the router. Reseat the cable interface line card in its slot (you do not have to turn off the system power when removing or replacing card). After the system re-initializes the interfaces, the enabled LED on the cable interface line card should go on.

c. If the enabled LED remains off after the above checks, it is likely that the system has detected a processor hardware failure. Contact a service representative for instructions.

Technical Assistance Center

The Cisco Technical Assistance Center (TAC) is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two levels of support are available: the Cisco TAC Web Site and the Cisco TAC Escalation Center.

Cisco TAC inquiries are categorized according to the urgency of the issue:

Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.

Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.

Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.

Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.

The Cisco TAC resource that you choose is based on the priority of the problem and the conditions of service contracts, when applicable.

Cisco TAC Web Site

You can use the Cisco TAC Web Site to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to this URL:

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to this URL to register:

http://www.cisco.com/register/

If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco TAC Web Site, you can open a case online by using the TAC Case Open tool at this URL:

http://www.cisco.com/tac/caseopen

If you have Internet access, we recommend that you open P3 and P4 cases through the Cisco TAC Web Site.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer automatically opens a case.

To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to this URL:

http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml

Before calling, please check with your network operations center to determine the level of Cisco support services to which your company is entitled: for example, SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA). When you call the center, please have available your service agreement number and your product serial number.
