Cisco uBR10-LCP2-MC16C/MC16E/MC16S Overview

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 85­to 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

on page 3). 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 on page 23.

While all other Cisco cable interface line cards transmit downstream signals to upconverters by using
the 44-MHz frequency, the Cisco uBR10-LCP2-MC16E transmits downstream IF signals to an up
converter by using the 36.125-MHz frequency.

Refer to the Cisco uBR7200 Series Universal Broadband Router Software Configuration Guide at the
following URL:

http://www.cisco.com/en/US/docs/cable/cmts/ubr7200/configuration/guide/cr72scg.html

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 Tab l e 2

on page 4.

• 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 on page 28.

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.

Cisco uBR10-LCP2-MC16C/MC16E/MC16S Cable Interface Card for the Cisco uBR10012 Router

10

OL-2872-02

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.

Removing and Replacing a Cisco uBR10-LCP2-MC16x Cable Interface Line Card

Removing and Replacing a Cisco uBR10-LCP2-MC16x Cable
Interface Line Card

Note This procedure applies to the Cisco uBR10-LCP2-MC16C, the Cisco uBR10-LCP2-MC16E, and the

Cisco uBR10-LCP2-MC16S cable interface line cards.

To remove and replace an individual cable interface line card you need the following tools and parts:

• Replacement cable interface line card (order number UBR10-LCP2-MC16C=,

UBR10-LCP2-MC16E=, UBR10-LCP2-MC16S=).

• ESD-preventive wrist strap.

• Antistatic surface or antistatic bag.

• Blank line card Cisco UBR10-MC-COVER= (if you are not replacing the card with another card).

Note For proper cooling and airflow, you must always install a blank cable interface line card cover in a blank

line card slot. The product order number for the blank cable interface line card cover is
Cisco UBR10-MC-COVER=.

Removing and Replacing a Cisco uBR10-LCP2-MC16x Cable Interface Line Card

Unpacking a Cisco uBR10-LCP2-MC16x Cable Interface Line Card

Tip Make sure that you are using the ESD-preventive wrist strap.

Step 1 Open the shipping carton by cutting the packing tape along the flaps on the top of the box.
Step 2 Remove the Cisco uBR10-LCP2-MC16x cable interface line card from the packaging.
Step 3 Place the card on an antistatic surface.

Removing a Cisco uBR10-LCP2-MC16x Cable Interface Line Card

Tip To prevent alarms from activating, you must administratively shut down a cable interface line card before

hot swapping it. Refer to the Cisco uBR7200 Series Universal Broadband Router Software
Configuration Guide at the following URL:

http://www.cisco.com/en/US/docs/cable/cmts/ubr7200/configuration/guide/cr72scg.html

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.

Use the following procedure to remove an existing cable interface line card from the Cisco uBR10012
chassis.

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 Line Card in the Cisco uBR10-LCP2 Adapter Card

The following section describes how to remove and replace a Cisco uBR-MC16x cable interface line card
in the Cisco uBR10-LCP2 adapter card.

Note Do not attempt to separate or remove the cable interface line card from the Cisco uBR10-LCP2 adapter

card while the combined cards are inserted in the chassis. You must remove the card as a unit; then,
separate the line card from the LCP2 adapter card on a lab bench or other area that protects against ESD
damage.

Tip To prevent alarms from activating, you must administratively shut down a cable interface line card before

hot swapping it. Refer to the Cisco uBR7200 Series Universal Broadband Router Software
Configuration Guide at the following URL:

http://www.cisco.com/en/US/docs/cable/cmts/ubr7200/configuration/guide/cr72scg.html

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.

Removing the Cable Interface Line Card from the Adapter Card

Note The Cisco uBR-MC16S main board also includes a daughter card . This daughter card is an integral part

of the card assembly and cannot be removed in the field.

Step 1 Ensure that you are properly grounded before handling the line card.
Step 2 Remove the cable interface line card from the chassis. See the “Removing a Cisco uBR10-LCP2-MC16x

Replacing the Line Card in the Cisco uBR10-LCP2 Adapter Card

Installing the Cisco uBR MC16x Cable Interface Line Card in the Adapter Card

Step 1 Ensure that you are properly grounded before handling the line card.
Step 2 Align the Cisco uBR10-MC16x cable interface line card with the guide rails on the Cisco uBR10-LCP2

adapter card. Ensure that the bottom of the cable interface line card is flush with the bottom of the LCP2
adapter card.

Step 3 Slide the new cable interface line card into the adapter card slowly, making sure that the card is sliding

under the spring guides and into the guides (see Figure 3 on page 7).

Step 4 Continue pushing on the front of the card until the connectors on the card are firmly seated in the

connectors on the adapter card. The ejector levers on each side of the card snap into place when the card
is fully inserted.

Step 5 Verify that the power connectors are aligned with those on the adapter card.
Step 6 Continue pushing on the front of the card until the connectors on the card are firmly seated in the

connectors on the adapter card. The ejector levers on each side of the card snap into place when the card
is fully inserted.

Step 7 Make sure that the screws on the adapter card brackets slide cleanly into the holes in the L-brackets.

Note These brackets help align the Cisco uBR10-LCP2 adapter card and Cisco uBR-MC16x cable interface

line card and hold the cable interface line card and the adapter card together.

Step 8 Tighten the captive screws on the cable interface line card to secure it to the LCP2 adapter card. See

Figure 12 on page 24.

Step 9 Replace the retaining washers and retaining nuts on the L-brackets (see Figure 13 on page 25). Make

sure that they are finger-tight.

Step 10 To secure the adapter card to the cable interface line card, turn the nuts a half-turn with the wrench.

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 on page 21).

OL-2872-02

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 on page 22).

Step 5 Secure the cable interface line card in the chassis by tightening the top and bottom captive screws (see

Figure 7 on page 18).

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 on page 27.

Troubleshooting the Cisco uBR10-LCP2-MC16x Cable Interface Line Card

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.
