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)
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:

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.
