Cisco uBR10-LCP2-MC16C/MC16E/MC16S Overview
The cable interface line cards, together with external IF-to-RF upconverters, serve as the RF interface between the cable headend and DOCSIS/EuroDOCSIS-based cable modems.
The Cisco uBR10-LCP2-MC16C, the Cisco uBR10-LCP2-MC16E, and the Cisco-LCP2-MC16S cable interface line cards are a combination of two components:
•Cisco uBR-MC16x (MC16C, MC16E, and MC16S) cable interface line cards—Provide one downstream and six upstreams channels.
–Cisco uBR-MC16C and Cisco uBR-MC16S support cable modems and set-top boxes that operate according to the Data-over-Cable Service Interface Specifications (DOCSIS). DOCSIS supports the 6-MHz North American channel plans using the ITU J.83 Annex B RF standard. The downstream uses a 6 MHz channel width in the 85- to 860-MHz frequency range, and the upstream supports the 5- to 42-MHz frequency range.
Note The Cisco uBR-MC16S main board also includes a daughter card that provides the advanced hardware-based spectrum management feature. This daughter card is an integral part of the card assembly and cannot be removed in the field.
–Cisco uBR-MC16E supports cable modems and set-top boxes that operate according to the European DOCSIS specifications (EuroDOCSIS). EuroDOCSIS supports the 8-MHz Phase Alternating Line (PAL) and SEquential Couleur Avec Memoire (SECAM) channel plans using the ITU J.112 Annex A RF standard. The downstream uses an 8 MHz channel width in the 85- to 860-MHz frequency range, and the upstream supports multiple channel widths in the 5- to 65-MHz frequency range.
•Cisco Line Card Processor (Cisco uBR10-LCP2) adapter card—Provides the mechanical and electrical conversions necessary for the Cisco uBR-MC16C, the Cisco uBR-MC16E, or the Cisco MC16S cable interface line card to fit the form factor used in the Cisco uBR100012 chassis.
Note Currently there are two types of LCP adapter cards, LCP and LCP2. The LCP is the original adapter card shipped with the Cisco uBR10-LCP-MC16x card. (Installation information about the LCP adapter card also applies to the LCP2 adapter card.) The Cisco uBR10-LCP2 adapter card is replacing the old LCP adapter card. The upgrade to the Cisco uBR10-LCP2 increases the memory from 64- to 256-MB. The upgrade supports N+1 requirements when the card is used as a redundant or protect card. There is no problem with the original LCP version if the card is used as the operating card. See the Proactive Upgrade Field Notice number 18301 at the following URL:
http://www.cisco.com/en/US/ts/fn/100/fn18103.html
The Cisco uBR10-LCP2 and Cisco uBR-MC16x cable interface line cards (MC16C, MC16E, and MC16S) are mechanically connected to each other by using brackets and power connectors (see Figure 1). The Cisco uBR10-LCP2 not only adapts the cable interface line card to the form factor of the Cisco uBR10012 chassis, but also provides:
•Proper voltage conversion for the cards and chassis.
•Boot code required to use the cable interface line cards.
•SDRAM for buffering packets as they are transferred between the card and PRE1.
The cards are inserted into and removed from the Cisco uBR10012 chassis as a single logical and physical unit. All Cisco uBR10-LCP2-MC16x cable interface line cards support online insertion and removal (OIR). OIR uses the MAC address assigned to the Cisco uBR10-LCP2 adapter card, allowing you to replace any Cisco uBR-MC16x cable interface line card installed on the adapter card without losing the configuration information.
Note Do not attempt to separate or remove the cable interface line card from the Cisco uBR10-LCP2 adapter card while they are 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. See the "Replacing the Line Card in the Cisco uBR10-LCP2 Adapter Card" section.
Figure 1 shows the Cisco uBR10-LCP2-MC16C cable interface line card.

Cisco uBR10-LCP2-MC16S
The Cisco uBR10-LCP2-MC16S:
•Consists of the Cisco uBR10-LCP2 adapter card, a motherboard (based on the Cisco uBR-MC16C cable interface line card) and an additional "piggy-back" spectrum management daughter card. The card is configured identically to the Cisco uBR-MC16S cable interface line card.
•Supports all DOCSIS downstream symbol rates and upstream channel widths as described in Table 2.
•Features advanced spectrum management capabilities made possible by hardware and software enhancements. The advanced spectrum management capabilities of the Cisco uBR10-LCP2-MC16S include the ability to hierarchically scan portions of the upstream spectrum for clean channels of varying widths.
The Cisco uBR10-LCP2-MC16S spectrum management card (daughter card) is able to sample the 5 to 42 MHz upstream frequency spectrum and initiate frequency hops, modulation change, or channel-width changes based on the sampled information. When specified thresholds have been reached, the spectrum management card takes a snapshot of the available upstream spectrum and then passes this information to the Cisco IOS software, where it is analyzed for indications of significant ingress or impulse noise. From this analysis, the Cisco IOS software draws informed conclusions regarding the "cleanest" portions of the upstream frequency spectrum to initiate a frequency hop to a clean upstream channel, if warranted. The user-defined threshold values are specified by commands in the configuration file of the Cisco uBR10012 router.
For Cisco IOS software requirements see the "Related Documentation" section.

Safety Information and Warnings
Following are safety guidelines that you should follow when working with any equipment that connects to electrical power.
 |
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030
|
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.

Step 1 Attach an antistatic wrist strap to your wrist and to a bare metal, unpainted surface on the chassis or frame.
Step 2 Face the back of the Cisco uBR10012 chassis. Clear enough interface and power cables to allow sufficient space to work.
Step 3 If installing a new cable interface line card in a blank slot, remove the blank slot cover and discard it. Otherwise, disconnect all coaxial cables from the cable interface line card being replaced or removed.
Step 4 Unscrew the top and bottom captive screws on the cable interface line card (Figure 7).
Step 5 Simultaneously pivot both ejector levers away from each other to disengage the cable interface line card from the backplane (Figure 8).
Step 6 Slide the cable interface line card out of the slot and place it on an antistatic surface or in an antistatic bag (Figure 9).
Step 7 If you are installing a new or replacement cable interface line card, continue with the next procedure. Otherwise, install a blank cover over the slot and screw down its captive screws to conclude this procedure.
Note For proper cooling and airflow, you must always install a blank cable interface line card cover in a blank line card slot. Product order number Cisco UBR10-MC-COVER=.

Replacing the Cisco uBR10-LCP2-MC16x Cable Interface Line Card in the Chassis
Tip 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 PRE.
Step 1 Ensure that you are properly grounded before handling the line card.
Step 2 Grasp the faceplate of the new cable interface line card with one hand and place your other hand under the card carrier (to support the weight of the card) and position the card in front of the card cage slot.
Step 3 Carefully align the upper and lower edges of the cable interface line card with the upper and lower guides in the chassis, and slide the card into the slot until you can feel it begin to seat in the backplane connectors (Figure 10).
Step 4 Simultaneously pivot both ejector levers toward each other (until they are parallel to the faceplate) to firmly seat the card in the backplane (Figure 11).
Step 5 Secure the cable interface line card in the chassis by tightening the top and bottom captive screws (see Figure 7).
Caution To ensure that there is adequate space for additional cable interface line cards, always tighten the captive screws on each newly installed card
before you insert any additional cards. These screws prevent accidental removal and provide proper grounding for electromagnetic interference (EMI) shielding.
Connecting the Cables
When fully inserted, the cable interface line card cycles through its power-on self-test. The Power LED is on (green) and the Status LED turns yellow. If the card is operating correctly, the Status LED then turns green. If these LEDs do not operate as described, see the "Troubleshooting the Cisco uBR10-LCP2-MC16x Cable Interface Line Card" section.
Step 1 Connect all downstream and upstream coaxial cables to the cable interface line card, as necessary.
Step 2 Configure the cable interface line card, if necessary.
For information about configuring the cable interface line card, refer to the Cisco uBR10012 Universal Broadband Router Software Configuration Guide at the following URL:
http://www.cisco.com/en/US/docs/cable/cmts/ubr10012/configuration/guide/scg.html
Troubleshooting the Cisco uBR10-LCP2-MC16x Cable Interface Line Card
To help isolate a problem with a card, check the following:
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 card has pulled away from the router. Reseat the card in its slot. You do not have to turn off the system power when removing or replacing a card. After the system reinitializes the interfaces, the enabled LED on the cable interface line card should come 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.
