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)

Cisco uBR10-LCP2-MC28C Overview
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.
Figure 1 shows the Cisco uBR10-LCP2 adapter card with the Cisco uBR-MC28C cable interface line
card installed.
Figure 1 Cisco uBR10-LCP2 Adapter Card and Cisco uBR-MC28C Cable Interface Line Card
The Cisco uBR10-LCP2-MC28C cable interface line cards, together with external IF-to-RF
upconverters, serve as the RF interface between the cable headend and DOCSIS-based cable modems
and set-top boxes (STBs). The cable interface line card supports 6-MHz National Television Systems
Committee (NTSC) channel operation, using standard (STD), Harmonic Related Carrier (HRC), or
Incremental Related Carrier (IRC) frequency plans conforming to EIA-S542. The card also supports
downstream channels in the 54 to 860 MHz range with upstream ranges of 5 to 42 MHz.
The two downstream ports and eight upstream ports support the modulations shown in Table 1:

Figure 4 shows the front panel for the Cisco uBR10-LCP2-MC28C cable interface line card.
Figure 4 Cisco uBR10-LCP2-MC28C Front Panel
The cable interface card has two downstream ports and eight upstream ports. Each downstream port is
associated with four upstream ports in a DOCSIS domain. Each domain runs independently of the other.
The Cisco uBR10-LCP2-MC28C cable interface line card uses a color-coded label to identify and group
the two downstream domains (DS0 and DS1). Their corresponding upstream ports are labeled U0
through U3.
The Cisco uBR10-LCP2 adapter card has its own set of status LEDs on top of the front panel. Table 2
describes the LCP2 card LEDs and their function.

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:
•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.
