Cabling the Cisco UBR-RFSW-ADV With the
Cisco uBR10012 Router
This chapter provides information about the protection scheme, supported cable types, and connecting cables
between the Cisco uBR Advanced RF Switch (Cisco UBR-RFSW-ADV) and the Cisco uBR10012 router.

Protection Scheme for the Cisco uBR10012 Router
The N+1 redundancy protection scheme you select for your system depends largely on the number and type
of cable interface line cards you have installed in your Cisco uBR10012 router. The 7 + 1 eight-card redundancy
scheme supports redundancy among the cable interface line cards installed in a fully populated Cisco uBR10012
router.
Note
The default protect line card slot in the Cisco uBR10012 router is subslot 5/1. However, you can configure
subslot 7/1 as the protect line card to better align the cables because this slot is directly below the PROTECT
section on the Cisco UBR-RFSW-ADV.
The protect cards slots are in the middle of the Cisco UBR-RFSW-ADV.

Using the Cisco UBR-RFSW-ADV with the Cable Interface Line Cards on the Cisco uBR10012 Router
Using the Cisco UBR-RFSW-ADV with the Cable Interface Line
Cards on the Cisco uBR10012 Router
A single Cisco uBR10012 router supports up to eight Cisco cable interface line cards. For this installation,
one Cisco UBR-RFSW-ADV is required to deploy a redundancy scheme in which one protect cable interface
line card supports from one to seven working cable interface line cards in the same chassis.
Each switch card on the Cisco UBR-RFSW-ADV supports a single UCH2 connector. Each upstream switch
cards connects to an upstream universal cable holder (UCH) cable assembly. This assembly provides ten
coaxial connections using two 5-way cables (one cable = 5 mini-coax cables).
Each downstream switch card connects to a downstream UCH cable assembly. This assembly provides 5
coaxial connections using one 5-way cable.
The total number of chassis cables are:
Note
Upstream-only version of the Cisco UBR-RFSW-ADV does not have downstream cables.
• On the CMTS side of the Cisco UBR-RFSW-ADV:
◦Upstream—16 upstream UCH cable assemblies
◦Downstream—8 downstream UCH cable assemblies
Total number of cable assemblies on the CMTS side is 24.
• On the Cable plant side of the Cisco UBR-RFSW-ADV:
◦Upstream—14 upstream UCH to F-Type cable assemblies. Each assembly provides 10 coaxial
connections using two 5-way cables.
◦Downstream—7 downstream UCH to F-Type cable assemblies. Each assembly provides 5 coaxial
connections using one 5-way cable
Total number of cable assemblies on the cable plant side is 21.
The line cards supported in the Cisco uBR10012 router are:
• Cisco UBR-MC20X20V
• Cisco uBR-MC3GX60V
For more information on these line cards, see:
• Cisco UBR-MC20X20V Cable Interface Line Card Hardware Installation Guide
• Cisco uBR-MC3GX60V Cable Interface Line Card Hardware Installation Guide
Supported Cable Types
The following sections describe the cables used with the Cisco UBR-RFSW-ADV.

Coaxial Cables
Coaxial Cables
The Cisco UBR-RFSW-ADV supports quad-shielded miniature precision video coaxial five-pack bundles
conforming to SCTE1 177 2012. These cables terminate with a 95-8687-01 Cisco Type II MCX style connector,
conforming to SCTE 176 2011and are held in a CAB-520-UCH2 type UCH2. The UCH is used to attach the
cables to the cards (see Figure 1: UCH2, on page 4 ).
The following list describes the cable bundles used with the cable line cards along with their part numbers:
• RF Cable bundle for Cisco UBR-RFSW-ADV: Cisco UBR-MC20X20 on Cisco uBR10012 router to

RS-232 Cables
These coaxial cables are approved for use in the Cisco N+1 redundancy solution. The 5- and 10-cable bundle
features individual coaxial cables enclosed in an external sheath. Each cable is a different color.
Figure 1: UCH2
Caution
Failure to use the UCH may cause permanent damage to the card connectors, resulting in low or no RF
output in the downstream or low or no RF input in the upstream.
RS-232 Cables
The system RS-232 cable (between the Cisco UBR-RFSW-ADV and the Cisco uBR10012 router) is a Cisco
style rolled cable. This cable has RJ-45 receptacles on both ends and is typically an unshielded twisted pair
cable.
Note
In a rolled cable, the colored wires at one end of the cable are in the reverse sequence of the colored wires
at the other end of the cable.

Mapping the RF Cables From the Working and Protect Line Cards
to the Cisco UBR-RFSW-ADV
This section describes the mapping of RF cables from the following working and protect cable line cards to
the Cisco UBR-RFSW-ADV.
• Connecting the Cisco UBR-MC20X20V Line Cards to the Cisco UBR-RFSW-ADV, on page 5
• Mapping the Cisco uBR-MC3GX60V Line Cards to the Upstream-Only Version of Cisco
UBR-RFSW-ADV, on page 21
Note
When you connect RF cables between the RF switch and a cable interface line card installed in a Cisco
uBR10012 chassis, ensure that all the RF cables in the bundle attach to interfaces on the same cable
interface line card installed in the Cisco uBR10012 chassis.
Connecting the Cisco UBR-MC20X20V Line Cards to the Cisco UBR-RFSW-ADV
The following table shows the mapping of the RF cables from the working and protect Cisco UBR-MC20X20V
line cards to the switch cards on the Cisco UBR-RFSW-ADV. Cisco cables are color-coded for easy reference
and installation. The cable color corresponds to a specific port on the card

Connecting the RF Cables From the Working and Protect Line Cards to the Cisco UBR-RFSW-ADV
Connecting the RF Cables From the Working and Protect Line
Cards to the Cisco UBR-RFSW-ADV
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.
Note
This procedure assumes that the RF cables are already installed in the UCH and mounted on the Cisco
cable interface line card. If the cables have not been installed in the UCH2 and mounted on the line card,
see the Cisco UBR-MC20X20V Cable Interface Line Card Hardware Installation Guide, or Cisco
uBR-MC3G60 Cable Interface Line Card Hardware Installation Guide depending on the cable interface
line card installed in the Cisco uBR10012 router.
Before You Begin
Have the following tool ready before performing this task:
• Slotted screwdriver
Procedure
Step 1
Step 2
Step 3
Step 4
Position the UCH2 so that the red line is on the same side as the red line on the card.
Align the end pins on the UCH2 with the pin holes in the faceplate. (See Figure 2: Installing the UCH2 on
the Faceplate, on page 31.)
Caution
When you are replacing the UCH2, be careful not to bend the cables in the holder at right
angles.
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.
Use the slotted screwdriver to tighten the leadscrew. Turn the leadscrew clockwise until it can no longer turn
(10 in-lbs, maximum torque 15 in-lbs).
Caution
Torquing the leadscrew to more than the maximum of 20 in-lbs can cause the leadscrew to
fail.

Connecting the RF Cables From the Cisco UBR-RFSW-ADV to the Cable Plant
Note
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).
Figure 2: Installing the UCH2 on the Faceplate
Step 5
Repeat Step 1 through Step 4 for the other two UCH2s.
Caution
To ensure proper installation and avoid poor connections, be sure that the cables are not positioned
at too acute an angle.

the Cable Plant
This configuration is similar to the Mapping the RF Cables From the Working and Protect Line Cards to the

Connecting the PRE With the Controller Card
This section describes how to connect the Performance Routing Engine (PRE) on the Cisco uBR10012 router
with the AUX port on the controller card in the Cisco UBR-RFSW-ADV.
Before You Begin
Have the following tool ready before you perform this task:
• RS-232 rollover cable with RJ-45 receptacles at both ends

Procedure
Step 1
Connect one end of the RJ-45 rollover cable to the serial RJ-45 port (labeled AUX) on the PRE module on
the Cisco uBR10012 router. See the following figure.

Step 2
Run the other end of the rollover cable through the square hole at the left front side of the chassis, and connect
it to the RJ-45 port (labeled COM) on the controller card on the Cisco UBR-RFSW-ADV. See the following
figure.
