Cisco uBR-MC3GX60V Cable Interface Line Card Hardware Installation Guide
Overview
Tip
Statement numbers (for example, Statement 1030) at the end of a Warning refer to specific warnings and
their translations in the Regulatory Compliance and Safety Information for the Cisco uBR10012 Universal
Broadband Router document.
Overview
The Cisco uBR-MC3GX60V cable interface line card transmits and receives RF signals between the subscriber
and the headend over the hybrid fiber-coaxial (HFC) system. This DOCSIS 3.0 compliant line card is designed
specifically for the Cisco uBR10012 universal broadband router and conforms to the Modular CMTS
(M- CMTS) architecture.
The Cisco uBR-MC3GX60V cable interface line card has the capacity to support 72 downstream (DS) and
60 upstream (US) channels, depending on the license purchased. The line card supports 15 cable MAC domains
(cable interfaces), and the DS and US channels can be associated with any of these 15 MAC domains. Each
MAC domain supports a maximum of 32 DS and 8 US channels.
The Cisco uBR-MC3GX60V cable interface line card has 20 US spigots for RF connectivity, which are
organized into 5 groups of 4 connectors each. Each connector group supports up to 12 frequency-stacked US
channels, with a default configuration of 3 US channels per RF connector. The line card also provides the
flexibility to configure lesser number of US spigots. For example, you can configure 10 US spigots with a
frequency-stacking of 6 US channels per spigot.
The Cisco uBR-MC3GX60V cable interface line card has six Gigabit Ethernet (GE) interface ports organized
into three pairs for DS connectivity. Each pair supports 1+1 redundancy and supports 24 DS channels in
Annex B mode by default. The GE interfaces connect to an external Edge Quadrature Amplitude Modulation
(EQAM) device and provide M-CMTS compliant Downstream External PHY Interface (DEPI) data. This
data is directed to only one GE interface, though both the GE interfaces can be active at the same time.
Upstream data from the subscriber comes through the upstream interfaces (US0–US59) on the Cisco
uBR-MC3GX60V cable interface line card. The line card processes and configures the data and sends it across
the backplane to the WAN or backhaul card and out to the Internet.
Downstream data to the subscriber comes from the Internet through the WAN or backhaul card, and across
the backplane to the Cisco uBR-MC3GX60V cable interface line card. The Cisco uBR-MC3GX60V cable
interface line card processes and configures the data and sends it out through the appropriate GE interface
ports (GE0–GE5) to the eQAM device to be sent to the HFC network.
The Cisco uBR-MC3GX60V 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 85 MHz range. The Cisco uBR-MC3GX60V cable interface line card supports Annex A and Annex B
RF data rates, channel widths, and modulation schemes and has DOCSIS MAC management and spectrum
management capabilities. It also supports DOCSIS-3.0, A-TDMA, S-CDMA, downstream bonding, and
upstream bonding rates.
Note
The Cisco uBR-MC3GX60V cable interface line card provides a higher downstream frequency range and
supports Annex A and Annex B RF data rates by interfacing with a DOCSIS 3.0 DRFI compliant EQAM,
like the Cisco RF Gateway 10.

Benefits
Note
You must ensure that two DOCSIS Timing, Communication and Control (DTCC) cards are configured
in the DOCSIS Timing Interface (DTI) mode on the Cisco uBR10012 router to make the
Cisco uBR-MC3GX60V cable interface line card work with an EQAM device.
The Cisco uBR-MC3GX60V cable interface line card uses a front panel display (FPD) to show the licensing
status information of the US and DS channels.
Figure 1: Cisco uBR-MC3GX60V Cable Interface Line Card, on page 3 shows the face plate of the line
card. The product ID (PID) of this card is UBR-MC3GX60V.

• Hardware-based support for DOCSIS 2.0 and DOCSIS 3.0 features such as S-CDMA, Multiple Logical
Channels, Upstream Channel Bonding, Per Service flow DS ID, and other DOCSIS 3.0 downstream
features.
• TDMA and S-CDMA multiple access support.
• Dynamic Bandwidth Sharing (DBS) in US and DS between DOCSIS 3.0 and legacy CMs sharing the
same channels.
• The Cisco uBR-MC3GX60V cable interface line card has three controllers. Each controller supports 32
Bonding Groups (BGs) consisting of 24 channels per DS BG and 4 channels per US BG.
• Reduced downtime as the Cisco uBR-MC3GX60V line card boots up to full functionality, after the
reload or ISSU upgrade process, in about 30 seconds.
• Expanded capacity of the Cisco uBR10012 universal broadband router, providing the highest port density
available in Cisco cable interface line cards.
• Additional flexibility for cable operators in partitioning the cable plant to address growing subscriber
bandwidth demands; enables cost-effective scalability of services and subscribers.
• Online insertion and removal (OIR), allowing key system components to be added or removed without
powering off the chassis.
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-MC3GX60V, Cisco UBR-MC20X20V, and the Cisco uBR-MC5X20H cable interface line cards.
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.
Software Licensing
The Cisco uBR-MC3GX60V cable interface line card supports software licensing for the US and DS
functionality. The software license restricts the US and DS channels the customer can use to 10 to 60 US
channels and 16 to 72 DS channels.
The Cisco uBR-MC3GX60V line card uses a smart chip authentication device to prevent counterfeit line
cards. A digital signature is embedded in the line card, and the Public Key Encryption techniques are used to
verify the authenticity of the digital signature. The software licenses are physically stored on the line cards.
You cannot transfer the software licenses between different line cards.
The Cisco uBR-MC3GX60V line card has a front panel four-character alphanumeric display to show the
licensing status information of the US and DS ports. The first two characters of the display represent the DS
license count and the last two characters represent the US license count.
Table 2: Cisco uBR-MC3GX60V Cable Interface Line Card License Information, on page 5 shows some
of the US and DS channel combinations supported on the Cisco uBR-MC3GX60V line card and their
corresponding license type.

Safety Information and Warnings
Follow these safety guidelines 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
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 wrist strap each time you handle the modules.
Follow these 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. Ensure 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 is
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
only on the body; ESD voltages on clothing can still cause damage.
Caution
For safety, periodically check the resistance value of the anti-static strap. The measurement should be
between 1 and 10 megaohms (Mohm).
Warning Definition
For Warning Definition, see 'Statement 1071' in Regulatory Compliance and Safety Information for the Cisco
uBR10012 Universal Broadband Router document.

SFP Module Interface Cables
SFP Module Interface Cables
After installing the SFP module in the GE port, you must attach the cables to the SFP module. The connector
types used to attach interface cables to the SFP Module are given below:
RJ-45 Connector
The RJ-45 connector, shown in Figure 24: RJ-45 Connector, on page 33, is used to provide full-duplex GE
connectivity to high-end workstations and between wiring closets over an existing copper network infrastructure.
Figure 24: RJ-45 Connector
1
RJ-45 connector and port
SC Fiber-Optic Connector
The SC Fiber-Optic connector, shown in Figure 25: SC Fiber-Optic Connector, on page 33, is used to connect
fiber-optic module ports or transceivers with the external SMF or MMF network.
Note
Ensure that the optical connectors are clean before making the connections. Contaminated connectors can
damage the fiber and cause data errors.
Figure 25: SC Fiber-Optic Connector

Cisco uBR-MC3GX60V Cable Interface Line Card Hardware Installation Guide
SFP Module Interface Cables
Note
Always insert the network connector completely into the socket. A secure connection is especially important
when you are establishing a connection between a module and a long distance (1.24 miles or 2 km) network
or a module and a highly attenuated network. If the link LED does not light up, try removing the network
cable plug and reinserting it firmly into the module socket. It is possible that dirt or skin oils have
accumulated on the plug faceplate (around the optical-fiber openings) generating significant attenuation
and reducing the optical power levels below threshold levels so that a link cannot be made.
LC Fiber-Optic Connector
The LC fiber-optic connector, shown in Figure 26: LC Fiber-Optic Connector, on page 34, is a small
form-factor fiber-optic connector that provides high density fiber connectivity. The line card connector can
be used with either MMF or SMF cables. The line card connector uses a latching clip mechanism that is similar
to the one used on the RJ-45 copper connector.
Note
Ensure that the optical connectors are clean before making the connections. Contaminated connectors can
damage the fiber and cause data errors.

Adding Heat-Shrink Tubing to Custom-built Cables
Adding Heat-Shrink Tubing to Custom-built 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.
Note
Heat-shrink tubing should be used only with Cisco uBR-MC3GX60V dual-shielded cables. Do not use
heat-shrink wrap with Cisco uBR-MC3GX60V quad-shielded cables.
Tools and Equipment for Heat-Shrink Tubing
• Heat-shrink tubing—See Technical Specifications and Component Part Numbers, on page 14.
• MCX cable prep tool (cable stripper)—White Sands Engineering part number CPT-7538-125 (for
dual-shielded cables).
• MCX cable crimping tool—White Sands Engineering part number ACT-483.
• MCX connectors—White Sands Engineering part number MCXFP (for dual-shielded cables).
• Cable—75–ohm precision miniature video cable, single strand bonded foil 1855 type.
• Heat source—To shrink the tubing around the cable (for example, a hand-held dryer).
Note
The heat-shrink tubing cannot be added if there is a connector on the end of the cable.
Adding Heat-Shrink Tubing
Procedure
Step 1
Step 2
Step 3
Cut the new cable to the desired length.
Strip the cable with the MCX cable prep tool per manufacturer instructions.
Cut a piece of heat-shrink tubing approximately 1-inch in length.
Note
The heat-shrink tubing has a 2:1 ratio for shrinkage (tubing has a 0.125-in. inside diameter with a
0.025-in. thick wall after recovery).

Troubleshooting the Line Card Installation
Step 4
Slide the tubing onto the cable.
Figure 33: Heat-Shrink Tubing on Cable Before Shrinking
Step 5
Install a MCX connector per manufacturers instructions.
Figure 34: Installing MCX Connectors
Step 6
Step 7
Step 8
Slide the heat-shrink tubing down the cable until the end is touching the connector.
Use a heat source (hand-held dryer) to shrink the tubing around the cable.
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.
Troubleshooting the Line Card Installation
If the Cisco uBR-MC3GX60V cable interface line card is not working properly, check the following:
1 Verify that the POWER LED is on (green). If the LED is off (not green):
• Verify that there is power to the system.
• Verify that the card is configured for the system.
2 Verify that the LEDs (see Table 11: Cisco uBR-MC3GX60V Line Card LEDs, on page 42 for LED
description) light up and go through the power on self test (POST) when the card is inserted in the chassis.
3 Verify that the captive screws and ejector levers are secure:
• Check that the captive screws are secure in the faceplate.

Troubleshooting the Line Card Installation
• Check that the ejectors levers are properly closed.
4 Verify that the card is properly seated in the chassis:
• Release the ejector levers and captive screws.
• Slide the card partially out of the chassis and then slide it back in, making sure that it is properly
seated in the backplane.
• Close the ejector levers and tighten the captive screws.
5 Verify that the UCH2 is securely in place on the faceplate. Check that the lead screw is secure.
Note
The recommended maximum torque for a lead screw is 15 in-lbs (1.69 Nm).
6 Verify that the connectors are properly seated in the ports on the faceplate:
• Verify that no cables are broken at the connector.
• Verify that the cables are properly secured in the UCH2.
• Verify that all the MCX connectors are protruding the same distance out of the UCH2.
Note
Use the MCX to F connector adapter to easily adapt the MCX connection for testing the cables.
7 Verify that the lock bar on the UCH2 is in place and tightened.
8 Verify that the correct level of software licensing is available for the card.
