Feature Overview
The Cisco UBR-MC20X20V cable interface line card is a 20 by 16 inch card designed specifically for
the Cisco uBR10012 universal broadband router. This card transmits and receives RF signals between
the subscriber and the headend over hybrid fiber-coaxial (HFC) system.
The Cisco UBR-MC20X20V line cards have five downstream (DS) ports and twenty upstream (US)
ports. The line card supports five cable MAC domains (cable interfaces), and the 20 DS and 20 US
channels are dynamically associated with any of these five MAC domains. The card has twenty US
spigots and five DS spigots. Each of the US spigots supports either two-frequency stacked US channels
across ten ports or a single US channel across twenty ports. Each of the DS spigots supports
four-frequency stacked channels across five ports.
Upstream data, from the subscriber, comes through the upstream ports (US0–US19) on the
Cisco UBR-MC20X20V cable interface line card. The line card processes and configures the data and
sends it across the backplane to the WAN/backhaul card and out to the Internet.
Downstream data, to the subscriber, comes from the Internet through the WAN/backhaul card, and across
the backplane to the Cisco UBR-MC20X20V cable interface line card. The Cisco UBR-MC20X20V
card processes and configures the data and sends it out through the appropriate rf-channel on a
downstream port (DS0–DS4) to be combined with the rest of the downstream signals in the headend.
The Cisco UBR-MC20X20V cable interface line card supports both DOCSIS and EuroDOCSIS cable
modem networks. The card supports downstream channels in the 55 to 999 MHz range, and upstream
channels in the 5 to 65 MHz range. The Cisco UBR-MC20X20V cable interface line card supports
Annex A and Annex B radio frequency (RF) data rates, channel widths, and modulation schemes and has
DOCSIS MAC management and spectrum management capabilities. DOCSIS-3.0, A-TDMA, S-CDMA,
downstream bonding, and upstream bonding rates are supported.
The Cisco UBR-MC20X20V cable interface line card has high line card CPU speed, memory, and flash
memory allowing support of Voice over IP (VoIP) at much higher call loads and a higher percentage of
modems running advanced DOCSIS features that typically consume line card CPU resources.
Note
You must ensure that two DOCSIS Timing, Communication and Control (DTCC) cards are configured
on the Cisco uBR10012 router before installing the Cisco UBR-MC20X20V cable interface line card.

Feature Overview
Onboard Failure Logging
The On-Board Failure Logging (OBFL) feature enables storage and collection of critical failure
information in the nonvolatile memory of a Field Replaceable Unit (FRU), like a Route Processor (RP)
or line card. The Cisco uBR10000 series universal broadband router supports OBFL on PRE4, the Cisco
SIP-600 jacket card, Cisco UBR-MC20X20V cable interface line card and the Cisco UBR-MC5X20H
cable interface line card.
The OBFL stored data assists in understanding and debugging field failures upon Return Material
Authorization (RMA) of a RP or line card at repair and failure analysis sites.
OBFL records operating temperatures, voltages, hardware uptime, and any other important events that
assist board diagnosis in case of hardware failures.
For more information on the feature, see the Onboard Failure Logging feature guide located at the
following URL:
http://www.cisco.com/en/US/docs/ios/12_2sx/12_2sxh/feature/guide/sxhobfl.html#wp1053048
Note
The output from the CMTS router may vary slightly compared to the output samples shown in the URL
mentioned above.
Logging details for OBFL
The logging details for the OBFL feature are described below:
•
OBFL is enabled by default. You need to enable the feature if it is disabled previously.
•
On the Cisco UBR-MC20X20V cable interface line card logging begins after the system starts up.
•
OBFL samples the Cisco UBR-MC20X20V cable interface line card temperature and voltage
sensors every five minutes.
•
Voltage data is stored only when it is different from the last stored record.
•
The maximum logging time is two hours, hence, a new record is stored every two hours, regardless
of data variation.
•
Fatal hardware events are logged with OBFL.
•
Logs are organized as current (continuous) and historical (summarized) data records.
•
OBFL logging has no impact on performance.
Storing OBFL Data
OBFL logs are recorded on the bootflash device of the Cisco UBR-MC20X20V cable interface line card.
The logs are maintained in a separate 2MB partition, distinct from the Bootflash filesystem partition
where the crash dumps are stored. OBFL log files are not accessible to the operator and their contents
can be viewed only by using the OBFL CLI commands.
Displaying OBFL Data
The show logging onboard command displays the logs from the OBFL data.
For information on OBFL commands, see the "Configuration Tasks" chapter in the Onboard Failure
Logging feature guide located at the following URL:

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 anti-static 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. Make sure that the chassis and/or rack has a
grounding cable installed. (For more information, see the Cisco uBR10012 Universal Broadband
Router Hardware Installation Guide.)
•
Handle components by the carrier edges only; avoid touching the card components or any connector
pins.
•
When removing a module, place it on an anti-static 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 anti-static strap. The measurement should be
between 1 and 10 megohms.

Caution
Always handle the card by the carrier edges because the upconverter on the bottom side of the line card
may be hot to the touch. Dropping the card can damage the carrier rails and card guides, making it
difficult to reinstall.
Step 3
Slide the card out from the chassis and place it on an antistatic surface or in a static shielding bag with
the component side up.
Step 4
If you are installing a new or replacement card, see the “Installing the Cisco UBR-MC20X20V Cable
Interface Line Card in the Card Slot” section on page 29. Otherwise, install a blank cover over the slot
and screw down its captive screws.
Caution
For proper cooling and airflow, always install a blank card cover in unused line card slots.

Carefully align the top and bottom edges of the card with the guides in the chassis.
Caution
Step 2
This Cisco UBR-MC20X20V cable interface line card weighs 16 lbs. Use both hands when handling the
card. Do not drop the card or otherwise damage the carrier rails. Bent or damaged rails can damage the
card guides and prevent line card installation. When installing cards for the first time, or when all the
captive screws of the card are loose, insert cards first in slot 5/1 and work towards slot 8/0 to prevent
uneven gasket pressure.
Slide the card into the slot. (See Figure 16.)

Step 3
Simultaneously close the ejector levers to secure the card in the backplane. (See Figure 17.)
Step 4
Engage and begin tightening the captive screws first by hand. Then, use either a T-10 Torx (included in
the line card accessory kit) or a common flathead screwdriver to tighten the captive screws between 5 to
7 in-lbs.
Caution
Always tighten the captive screws on each line card, but not more than the maximum of 7 in-lbs. These
screws prevent accidental removal and provide proper grounding for electromagnetic interference (EMI)
shielding.

Cisco UBR-MC20X20V Cable Interface Line Card Hardware Installation Guide
Installing or Replacing a Cisco UBR-MC20X20V Cable Interface Line Card
Note
When fully inserted, the line card cycles through its power-on self-test, and the POWER and STATUS
LEDs turn on. (If either of those LEDs is flashing, see the “Troubleshooting the Cisco UBR-MC20X20V
Cable Interface Line Card Installation” section on page 41).
Installing UCH2 on the Cisco UBR-MC20X20V Cable Interface Line Card
Caution
The UCH2 must be used for all cable connections to the line card. Failure to use a UCH2 may cause
permanent damage to the line card connectors, resulting in low or no RF output in the downstream or
low or no RF input in the upstream.
To install UCH2, complete the following steps:
Step 1
Position UCH2 so the red line is on the same side as the red triangle on the card.
Step 2
Align the end pins on UCH2 with the pin holes in the faceplate. (See Figure 18.)
Caution
When you are replacing the UCH2, be careful not to bend the cables in the holder at right angles.
Step 3
While holding the UCH2 and cables in place on the faceplate, use your fingers to tighten the leadscrew.
If the UCH2 and cables do not appear to settle securely in place on the faceplate, wiggle the holder to
resettle the connectors. (See Figure 19.)
Step 4
Use the flathead screwdriver to tighten the leadscrew. Turn the leadscrew clockwise until it will no
longer turn (10 in-lbs, maximum torque 15 in-lbs).
Caution
Note
Torquing the leadscrew to more than the maximum of 20 in-lbs can cause the leadscrew to fail.
As you turn the leadscrew clockwise, the outer shroud on the UCH2 moves to cover the red line on the
top and the black line on the bottom of the UCH2. The half circles on the edge of the shroud appear to
close as the shroud fits down over the UCH2. Full engagement is indicated by visible metal-to-metal
contact between the UCH2 and the faceplate (check the half circle cutouts).

Adding Heat-Shrink Tubing to Custom Built Cables
Note
Step 5
Repeat Step 3 and Step 4 for the remaining cables you are installing.
Note
Step 6
The cables fit loosely in the holes, and are not locked into place until the lock bar is closed in
Step 6.
Make sure the cables are aligned correctly and inserted completely or the slide bar will not close.
Slide the lock bar close completely, and use the T-10 TORX driver tool to tighten the screws clockwise
(torque 10 in-lbs, 1.13 Newton meters (Nm)).
Note
Clamp bar maximum torque 15 in-lbs (1.70 Nm).
Adding Heat-Shrink Tubing to Custom Built Cables
Note
Heat-shrink tubing should be used only with MC20X20V dual-shielded cables. Do not use heat-shrink
wrap with MC20X20V quad-shielded cables.
The heat-shrink tubing adds rigidity to the connection between the connector and the cable. The tubing
is not required, but recommended. This procedure describes how to add heat-shrink tubing to the cables.

Step 6
Slide the heat-shrink tubing down the cable until the end is touching the connector.
Step 7
Use a heat source (hand-held dryer) to shrink the tubing around the cable.
Step 8
If the tubing overlaps the connector after it has shrunk, cut back the shrink tubing to the end of the
connector.
Note
If the tubing overlaps the connector, the connector will be difficult to install in the UCH2 slot,
and the UCH2 may not function properly.
