Rack-Mounting the Cisco uBR 3x10 RF Switch with the Cisco uBR10012 CMTS
Warning 
Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030
1 Overview
This quick start guide provides basic instructions for rack-mounting a Cisco uBR 3x10 RF Switch in a 4-post equipment rack with the CiscouBR0012 CMTS.
Before proceeding with the installation, review the safety information in the Cisco RF Switch Regulatory Compliance and Safety Information.
Tip To prevent overheating, install the RFSwitch in an area that is properly ventilated or air conditioned.
Sample Configurations
The following illustrations show sample configurations using the Cisco uBR3x10 RF Switch in a Cisco uBR10012 CMTS.

2 Required Equipment
The following equipment is required for rack-mounting the Cisco uBR 3x10 RF Switch in a standard 19-inch-wide 4-post equipment rack.
Note The rack-mount brackets that come in the accessory kit cannot be used with other racks, such as 23-inch telco racks
Tools and Equipment
•Number 2 Phillips screwdriver
•7/16-inch flat-blade screwdriver
•Eight 1/32 x 3/8 slotted screws
•Two M5 hex-head screws
•4 AWG ground wire
•Ground lug
•Heat-shrink tubing
•Cable management bracket
•Two M5 x 8-mm Phillips countersunk screws
•Two rack-mount brackets
•Four M5 x 8-mm Phillips countersunk screws
Cables Used with These Configurations
•3-m cables—CAB-RFSW5X20TPMF,
MCX to MCX connector
•1-m cables—CABRFSW520TIMM,
MCX to MCX connector
•10-m cables—CABRFSW-3X10-10T,
MCX to F connector
•1.2-m cables—CAB-RFSW-3X10-T,
MCX to F connectors
Tip For detailed installation and cabling instructions, refer to the Cisco uBR 3x10 RF Switch Hardware Installation and Cabling Guide.
3 Attaching the Brackets
Step1 Locate the threaded holes at the front of the RF Switch chassis (both sides).
Step2 Align the first rack-mount bracket with the threaded holes in the left-front side of the chassis.
Step3 Thread the M5 x 8 mm Phillips screws through the rack-mount bracket and into the side of the chassis.
Step4 Use the number 2 Phillips screwdriver to tighten the screws.
Step5 Repeat Step 1 through Step 4 for the other bracket.

4 Rack-Mounting the Switch
Caution Two people should perform this installation procedure.
Step1 Ensure that all the modules are secure in the chassis.
Step2 Position the chassis so that the rear panel is facing the same way as the connectors on the cards. See Figure1 and Figure2.
Step3 Slide the chassis into the rack. Use the illustrations to determine where you attach the chassis to the rack. See Figure1 and Figure2.
Step4 While keeping the brackets flush against the posts or mounting strips, position the chassis so that the holes in the brackets are aligned with those in the mounting strips.
Note Use all four screws to fasten the two rack-mount brackets to the rack posts, because the brackets support the weight of the chassis (36.6 lbs (16.6 kg).
Step5 Insert all four 1/32 x 3/8 slotted screws (two on each side) through the brackets and into the mounting strip.
Tip Insert the bottom screws first.
Step6 Tighten all the screws.
5 Grounding the Chassis
Caution Before connecting power and turning on the RF Switch, you must provide an adequate earth ground connection.
Step1 Locate the ground lug holes on the left-side rear of the chassis.
Step2 Using 4 AWG wire (recommended), insert the wire into the ground lug.
Step3 Cover any exposed wire with heat-shrink tubing.
Step4 Use the two M5 hex-head screws to attach the grounding lug to the chassis.
Step5 Attach the wire to an appropriate earth ground location.

Attaching the Cable Management Bracket
A cable management bracket is included in the shipping container. We recommend using this bracket to ensure proper airflow in the chassis.
Step1 Locate the threaded holes in the right-rear and left-rear side of the Cisco uBR10012 chassis. See Figure1 and Figure2.
Step2 Align the cable-management bracket with the threaded holes
Step3 Thread the countersunk screws through the bracket and into the chassis.
Step4 Tighten the screws.
