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.html.
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)

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

Replacing the Cisco uBR-MC28C Line Card in the Cisco uBR10-LCP2 Adapter Card
Connecting the Cables
When fully inserted, the cable interface line card cycles through its power-on self-test. The Power LED
turns on (green) and the Status LED turns on (yellow). If the card is operating correctly, the Status LED
turns green. If these LED do not operate as described, refer to
Troubleshooting the Cisco uBR10-LCP2-MC28C Cable Interface Line Card, page 23 and the
Cisco uBR10012 Universal Broadband Router Hardware Installation Guide at the following URL:
http://www.cisco.com/univercd/cc/td/doc/product/cable/ubr10k/ubr10012/index.htm
Note
It is not necessary to configure the cable interface line card if you are installing a replacement card in
the identical slot. The system automatically downloads the necessary configuration information from the
PRE1.
Step 1
Connect all downstream and upstream coaxial cables to the cable interface line card.
Step 2
Configure the cable interface line card if necessary.
For information about configuring the cable interface line card, refer to the Cisco uBR10012 Software
Configuration Guide at the following URL:
http://www.cisco.com/univercd/cc/td/doc/product/cable/ubr10k/ubr10012/index.htm
For configuration information, refer to Configuring the Cisco uBR-MC28C Cable Modem Card,
available on the documentation CD-ROM and Cisco.com at the following URL:
http://www.cisco.com/univercd/cc/td/doc/product/cable/cab_r_sw/flmc28.htm.
Replacing the Cisco uBR-MC28C Line Card in the
Cisco uBR10-LCP2 Adapter Card
The following section describes how to remove and replace an uBR-MC28C cable interface line card in
a Cisco uBR10-LCP2 adapter card.
Note
Do not attempt to separate or remove the Cisco uBR-MC28C cable interface line card from the
LCP2 adapter card while the combined cards are inserted in the chassis. The cards must be removed as
a unit and then separated on a lab bench or other area that protects against ESD damage.
To prevent alarms from activating, you must administratively shut down a cable interface line card before
hot swapping the card. Refer to “Shutting Down and Restarting the Interface” in the Cisco uBR10012
Software Configuration Guide at the following URL:
http://www.cisco.com/univercd/cc/td/doc/product/cable/ubr10k/ubr10012/index.htm
See the release notes at the following URL:
http://www.cisco.com/univercd/cc/td/doc/product/cable/ubr10k/ub10krns/index.htm
Otherwise, inform the network administrator that this portion of the network will be temporarily
interrupted. If the maintenance LED is on, you can remove the cable interface line card without affecting
systems operations.

Troubleshooting the Cisco uBR10-LCP2-MC28C Cable Interface
Line Card
Check the following to help isolate a problem with a card:
Step 1
Are all enabled LEDs on?
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:

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
