Required Materials

  • Mounting bracket and hardware as described in the Mounting Bracket Kit

  • 13-mm box-end socket wrench

Procedure

Step 1

Assemble six sets of bracket hardware (washer, split-lock washer, and bolt), as detailed in Assemble Bracket Hardware.

Step 2

Place the mounting bracket (6) against the mounting plate by inserting the bracket quick-hang notch (2) over the mounting plate quick-hang stud (5).

Step 3

Thread the serrated nut onto the quick-mount stud (4) and hand tighten (do not over tighten).

Step 4

Align the pivot grooves (7) on the bracket with four of the bracket-mount holes (1) on the mounting plate. Follow these guidelines:

  • Each of the four pivot grooves on the bracket must be attached to at least one bracket-mount hole on the mounting plate.

  • The final orientation of the mounting plate and router determine which bracket-mount holes are used.

  • Mount the router, as described in Installing the Mounting Plate On To a Pole.

Step 5

Insert one bolt assembly (3) through one of the pivot grooves (7) on the bracket and then through the corresponding bracket mount hole on the mounting plate.

Step 6

Repeat Step 5 for the remaining bolt assemblies.

Step 7

Position the mounting-bracket onto the mounting plate, as needed, before further tightening the bolts.

Step 8

Use a socket wrench to evenly tighten all four bolts and the serrated nut to finish installing the bracket on the plate. Use a torque of 6 to 7 foot-pounds when tightening the bolts and nut.

Attach the Router Onto the Mounting Bracket

This section describes how to attach the IR8140H to the mounting bracket.

Required materials:

  • 13-mm box-end socket wrench

  • Two sets of bracket hardware (split-lock washer, regular washer, and bolt). Attach each of the bracket sets to opposite sides of the IR8140H to provide support and enable it to rest on the bracket to each side of the router (see Assemble Bracket Hardware Set).

Procedure

Step 1

Attach two sets of bracket hardware, one on either side of the IR8140H router.

Step 2

Slide the router onto the bracket and rest it on the two quick-hang slots (see Mounting Bracket Details).

Step 3

Use a socket wrench to evenly tighten the two sets of bracket hardware to secure the router to the mounting bracket.

Figure 13. IR8140H Attached to the Mounting Bracket

Step 4

You are now ready to ground the router. See Grounding the Router.

Installing the Security Bracket on the Router

The security bracket is used to secure the CPU, UIMs, and BBU on the router with a padlock. (The padlock is not provided by Cisco.)

Follow these steps to install the security bracket.

Before you begin

Ensure all bolts and screws on the unit are tightened. Every module slot should have a module or a cover installed. Ensure the plastic CPU console port plug is installed and tight. This plug should be found on the bottom right side of the unit and should be screwed into the front-most hole on the bottom module.

Procedure

Step 1

Hang the CPU security bracket (2) onto the slot (3) on the bottom of the chassis. When looking at the front of the chassis, the slot will be found at the bottom right of the chassis towards the front. Insert the U-shaped flange of the CPU security bracket into the slot from the inner side of the chassis, so that the opening of the U-shape comes out of the outside of the chassis. The CPU security bracket should be able to hang freely on the slot. See the following figure.

3

Slot on the bottom of the chassis to install the CPU security bracket

Step 2

Hold the long front BBU security bracket (1) and attach it from the top of the chassis. It should be done at an angle in order to correctly mount the top two holes on the top screws. It should fit over the top two inner screws on each top module. Notice that the security bracket only fits in one direction. It is not symmetrical. There is a top and a bottom of the bracket.

The following figure shows the top two screws (2) to align the security bracket over and fit onto.

Step 3

Once the bracket is seated over the top screws, slowly rotate the bracket closer to the front of the chassis. At the same time, one hand should be used to lift the bottom, circular, CPU bracket so that the slot in the CPU bracket lines up with the bottom right flange of the BBU bracket so that they click into place. This will ensure a safe mount of the CPU bracket. The flange on the CPU bracket should be seated above the flange of the front BBU security bracket.

The following figure shows the mounted BBU security bracket and CPU security bracket.

Step 4

Use the M6 size bolt (1) included with the bracket to secure the bracket into place on the front of the chassis through the hole in the middle of the chassis front BBU cover. Torque to 15 to 20 in-lbs.

Step 5

Secure the BBU bracket and the unit with a padlock to the padlock tab on the front slot (1).
