Installation Methods The Cisco cBR-8 router can be either mounted on the rack at the front or in the middle. Also, the router can be either mounted on a standard 19-inch wide four-post equipment rack unit or a two-post rack unit.

Procedure Step 1 Mark and measure the distance between two holes on the left and right mounting rails. The distance should measure 18.31 inches ± 0.06 inches (46.5 cm ± 0.15 cm). Measure the pairs of holes near the bottom, middle and top of the equipment rack to ensure that the rack posts Note are parallel.
Page 4 If there is a second internal rack rail that is no more than 23 inches from the front rail, position the second installation bracket to create a rear support for the chassis during installation. Figure 2: Chassis Installation Bracket Chassis Installation Bracket Note After the chassis is installed and secured to the rack the chassis installation brackets can be removed from the rack.
Page 5: Attaching The Chassis Rack-Mount Brackets
Attaching the Chassis Rack-Mount Brackets Before installing the chassis in the rack, you must install the rack-mount brackets on each side of the chassis. The rear RF cable-management brackets are installed on the chassis after you install the chassis rack-mount Note brackets and mount the chassis in the rack.
Page 6 Procedure Step 1 Remove the rack-mount brackets installed at the front of the chassis by unscrewing the M5 undercut flat-head screws using a #2 Phillips torque screwdriver. Step 2 Locate the threaded holes at the middle on the side of the chassis that align with the holes in the rack-mount bracket. Step 3 Install the 10 M5 undercut flat-head screws to secure each rack-mounting bracket to the chassis.

Installing the Chassis Installation Handle (Optional) Before You Begin Required Tools and Equipment • #2 Phillips screwdriver Restrictions Do not install the chassis installation handle if the chassis is to be mid-mounted in the rack. Procedure Step 1 Locate two M5 threaded holes on each chassis rack mount bracket that align with the chassis lifting handle captive screw holes.
Page 8 Caution Ensure that the captive screws are tightly secured before loading the handles to prevent injury or damage to the chassis. Figure 4: Attaching the Chassis Installation Handles to the Cisco CBR-8 Converged Broadband Router Chassis Installation Handle Chassis Captive Screw —...
Page 9: Installing The Cisco Cbr-8 In A Rack
Installing the Cisco cBR-8 In a Rack Rack mount the chassis by securing the rack-mount brackets to two posts or mounting strips in the rack. Use at least four rack-mount screws on each side to fasten the two rack-mount brackets to the rack posts because the rack-mount brackets support the weight of the entire chassis.
Page 10 area handles or by placing your hands underneath the bottom of the chassis. With the installation handle installed, you can tilt the chassis up in the front in order to get your hands underneath the bottom of the chassis. Figure 5: Lifting the Chassis into Position...
Page 11 Step 4 After the rear weight of the chassis is resting on the installation bracket, one person can hold it in place while the second person moves to the rear of the rack to help slide it into place and hold the weight while the rack mount screws are tightened. Step 5 Position the chassis until the rack-mounting flanges are flush against the mounting rails on the rack.
Page 12 Installing the Cisco cBR in a Two-Post Rack The Cisco cBR chassis can be installed in a two-post 19-inch rack either as a front mount or a mid-mount. The procedure for the front mount option in a two-post rack is identical to the procedure for front mounting in a four-post rack except you cannot use the second chassis installation bracket.
Page 13 c) Insert a minimum of four screws per bracket on both sides of the chassis. Step 8 Ensure that all the screws on each of the side rack-mount brackets are tightened to the equipment rack before the chassis installation bracket is removed from the rack.

Page 14: Attaching The Cable-Management Brackets
Each RF cable-management bracket for the Cisco cBR chassis contains four independent "U" type cable-management provisions, with two captive screws for attaching to the chassis, and provides cable dressing of each RF PIC card slot.

Page 21: Attaching A Chassis Ground Connection
Before you connect power or turn on power to your chassis, you must provide an adequate chassis ground (earth) connection for the chassis. A chassis ground connector is provided on each Cisco CBR-8 chassis. The grounding wire is always the first to be installed or connected and the last to be removed or Caution disconnected.
Page 22 • 4 or 2 AWG grounding wire—The ground wire and lug should always be as big as the input gauge. For example, to use 2 AWG for the DC inputs, the ground lug and wire should be 2 AWG or bigger. •...
Page 23 Step 6 Connect the opposite end of the grounding wire to the appropriate grounding point at your site to ensure an adequate chassis ground.
