Introduction

The Cisco uBR Advanced RF Switch (Cisco UBR-RFSW-ADV) provides N+1 line card redundancy switching for the Cisco uBR10012 universal broadband router also known as the Cisco CMTS. The Cisco UBR-RFSW-ADV is a rack-mount unit controlled by the Cisco uBR10012 router.

Overview

The Cisco UBR-RFSW-ADV is located between the Cisco uBR10012 router and the cable plant. All the RF downstream (output) and RF upstream (input) ports of the Cisco uBR10012 router are connected to one side of the Cisco UBR-RFSW-ADV, while the cable plant is connected to the other side.

The Cisco uBR10012 router supports up to eight cable interface (RF) line cards. Each line card supports a single downstream Universal Cable Holder (UCH) connector (five RF ports per connector) and two upstream UCH connectors (ten RF ports per connector).

When supporting N+1 redundancy, the Cisco uBR10012 router allocates one of the eight line cards as a protect line card.

There are 24 cards on the rear of the Cisco UBR-RFSW-ADV. Each card supports one UCH connector. These cards are arranged in eight groups of three cards each. In the middle is the protect card group, which consists of one downstream protect and two upstream protect cards (see Figure 2). This protect card group connects to the Cisco uBR10012 router protect line card. To either side of the protect cards are groups of switch cards—one downstream switch card and two upstream switch cards per group. These groups of switch cards connect to the remaining line cards on the Cisco uBR10012 router.

On the front of the Cisco UBR-RFSW-ADV are 21 interconnect cards. These cards are arranged in seven groups of three cards each. Each group contains one downstream interconnect card and two upstream interconnect cards. These interconnect cards connect to the cable plant.

When the Cisco uBR10012 router and Cisco UBR-RFSW-ADV are not in protect mode, each interconnect card group is switched to a corresponding line card on the Cisco uBR10012 router. However, when the Cisco uBR10012 and Cisco UBR-RFSW-ADV are in protect mode, the interconnect card group associated with the failed cable interface line card is switched to the protect line card group instead.

The Cisco uBR10012 router manages all protect switching control plane events and system upgrades.

The Cisco uBR10012 router requires Cisco IOS Release 12.2(33)SCG and later releases to operate the Cisco UBR-RFSW-ADV.

Cisco IOS Release 12.2(33)SCG and later releases for Cisco uBR10012 router are required for operation with the Cisco UBR-RFSW-ADV. When the Cisco uBR10012 router determines that a cable interface line card failure has occurred, it enters into protect mode and additionally commands the Cisco UBR-RFSW-ADV to enter protect mode.

The Cisco UBR-RFSW-ADV supports the following line cards on the Cisco uBR10012 router:

  • Cisco UBR-MC20X20V
  • Cisco uBR-MC3GX60V

The Cisco UBR-RFSW-ADV enhances overall system usability by providing easy cabling using the same quick-connect UCH system used on all Cisco uBR10012 router cable interface line cards.

The Cisco UBR-RFSW-ADV provides the following enhancements over the earlier Cisco uBR 3x10 RF Switch units:

  • One Cisco UBR-RFSW-ADV replaces two uBR 3x10 RF Switch units.
  • UCH type connectors allow easy cabling and improved RF and electromagnetic interference (EMI) performance.
  • Image upgrade is improved.
  • RF path performance is improved with significantly less insertion loss.
  • 54 to 1002 MHz downstream frequency range.
  • 5 to 85 MHz upstream frequency range.
  • Fully-redundant control ports.

                  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:

                  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   Position the UCH2 so that the red line is on the same side as the red line on the card.
                    Step 2   Align the end pins on the UCH2 with the pin holes in the faceplate. (See Figure 1.)
                    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.
                    Step 4   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.

                    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 22. 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.

                              Alarm condition.


                              Note


                              Only the upper LED is used for downstream switch cards.


                              Each upstream switch card has two LEDs and each downstream switch card has one LED to indicate the working status of the port. The upstream switch module operates over the frequency range of 5 MHz to 85 MHz. The downstream (high-frequency) switch module operates over the frequency range of 54 MHz to 1002 MHz. During normal system operation, upstream switches all direct traffic to their respective default termination interfaces.

                              The switch card should provide a minimum of 65 dB of isolation from connector port to connector port during normal operation and more than 65 dB when operating in protect mode.

                              When an upstream or downstream switch module initially boots, the LEDs briefly cycle on in sequence.

                              If you are unable to resolve the problem, see Obtaining Documentation and Submitting a Service Request for information on contacting Cisco technical assistance.
