Installing the Front (PLIM) Side Exterior Cosmetic Components

This section describes how to install the default front (PLIM) side exterior cosmetic components (Figure 5-1) on the Cisco CRS Series enhanced 16-slot line card chassis.


Note While it is possible to install the various exterior components on the Cisco CRS Series enhanced 16-slot line card chassis in a different order, it is easier to install them in the order outlined in this section.


The lower grille screen and frame assembly are shipped pre-installed in the chassis. The upper grille support is not shipped pre-installed on the chassis but must be installed before the power shelves are installed in the chassis. For more information, see the“Installing the Upper Grille Support” section

This section describes how to perform the following tasks:

Prerequisites

Before performing this task, you must first unpack and secure the chassis. See the Cisco CRS Carrier Routing System 16-Slot Line Card Chassis Unpacking, Moving, and Securing Guide.

The upper grille support should already be installed at the top of the chassis. See the “Installing the Upper Grille Support” section for more information.

Required Tools and Equipment

You need the following tools and parts to perform this task:

  • 8-in. long number 1 Phillips screwdriver—magnetic head preferable, bit size #1
  • 3/8-in. drive ratchet wrench
  • Default vertical cable troughs (Cisco product number 800–35625–xx [right], 800–35644–xx [left])
  • Optional wide vertical cable troughs (Cisco product number 800–36457–xx [right], 800–36456–xx [left])
  • Optional cable pass-through accessory kit (Cisco product number CRS–LCC–CM–COVER), used with default cosmetics
  • Upper grille (Cisco product number 800–35465–xx)
  • Lower grille (Cisco product number 800–35466–xx)

Step 2 Attach the vertical cable troughs—one right and one left—to the front (PLIM) side of the chassis (see Figure 5-4):


Note The part number for the right side vertical cable trough is 800–35625–xx; the part number for the left side vertical cable trough is 800–35644–xx.


a. Tug all Velcro straps forward so that they are flush with the back side of the cable troughs (where the troughs attach to the chassis) to ensure that the troughs fit flush to the chassis.

b. Insert the cable trough positioning studs into the guide slots on the unistrut, and let them slide down and lock into place.

c. Insert the 10 M4x14-mm flat head screws (five on each trough) and use the screwdriver to turn the screws clockwise to attach the cable troughs firmly to the front of chassis.

Figure 5-4 Installing the Front Vertical Cable Troughs

 


 

Installing the Cable Pass-through Accessory Plates (Optional)—Default Cable Trough Only


Note Depending on the size of the installation and the number and type of cables being used, the body of the chassis may become overcrowded and unable to accommodate all the required cables. To resolve this issue, you can install two pass-through accessory plates to allow cables be guided outside the default vertical troughs.


Step 3 Remove the blank plates by unscrewing the four screws on each one.

Step 4 Attach the inner cut-out plates using the four screws provided. See Figure 5-5.

Figure 5-5 Cut-Out Plates

 

Step 5 Attach the outer cut-out plate using the four screws provided.

Step 12 Insert the screws into the appropriate screw holes in the doors, and use the screwdriver to tighten fully. There are 11 M4x8 screws on each side for the metal sections of the doors and six M4x8 screws on each side for the plexiglass section of the door.


Note To ensure that the door is well supported during installation, insert screws in the upper and lower metal sections first.


Step 13 Ensure that the doors are properly aligned.

The following substeps apply to the default cosmetics.


Note Typically, the doors will close without interfering with each other. However, you may need to adjust either the left or right door, or both, to align the doors properly. Adjust doors only if necessary.


a. Check to see if the doors close without interfering with each other.

b. To decrease the door gap, loosen the screws that secure the vertical trough to the chassis. Using the 2 mm hex key wrench, tighten the bottom set screws one full turn. Snug the screws that attach the vertical trough to the chassis and check the door alignment.

c. To increase the door gap, loosen the screws that secure the vertical trough to the chassis. Using the 2 mm hex key wrench, tighten the top set screws one full turn. Snug the screws that attach the vertical trough to the chassis and check the door alignment.

d. Repeat the procedure as necessary until the doors are properly aligned.

e. Tighten the screws that secure the vertical trough to the chassis.

Step 14 For wide duct installations (see Figure 5-11):

a. Ensure that the doors are properly aligned.


Note Typically, the doors will close without interfering with each other. However, you may need to adjust either the left or right door, or both, to align the doors properly. Adjust doors only if necessary.


b. Check to see if the doors close without interfering with each other.

c. (Minor adjustments) Increase or decrease the door gap by loosening and adjusting the eleven (11) screws on each door as needed.

d. (Major adjustments) Increase or decrease the door gap by loosening the seven (7) screws on the vertical metal bar on each door as needed.

e. (Major adjustment) Using a flat blade screwdriver, insert it in the adjustment bracket (upper and lower) and pry either left or right to increase or decrease the door gap (see Figure 5-11).

Installing the Rear (MSC) Side Cosmetic Components

This section describes how to install the rear (MSC) side exterior cosmetic components on the Cisco CRS Series enhanced 16-slot line card chassis. While it is possible to install the various exterior components on the chassis in a different order, it is easier to install them in the order outlined in this section. Figure 5-3 shows the exterior cosmetics for the rear (MSC) side of a Cisco CRS Series enhanced 16-slot line card chassis.

The midchassis cable management bracket and rear door strike tube are shipped pre-installed on the chassis.

This section contains the following procedures:


Note For instructions on installing the rear cosmetics if the vertical trough is not used, see Attaching the Upper Rear Air Grille and Rear Kick Plate Without Vertical Troughs


Prerequisites

Before performing these tasks, you must first unpack and secure the chassis. See Cisco CRS Carrier Routing System 16-Slot Line Card Chassis Unpacking, Moving, and Securing Guide.

Required Tools and Equipment

You need the following tools and parts to perform this task:

  • 8-in. long number 1 Phillips screwdriver—magnetic head preferable #1
  • Rear vertical cable troughs (included in CRS-16-REAR-CM)
  • Rear kick plate (included in CRS-16-REAR-CM)
  • Upper air grille (CRS–16–REAR–GRL)
  • Rear doors (CRS–16–DOORS–R)
  • Upper rear air grille with mounting brackets (CRS-16-REAR-GRL), only if vertical troughs are not used
  • Rear kick plate with mounting brackets (CRS-16-KP-REAR), only if vertical troughs are not used

Steps

To install the rear (MSC) exterior cosmetic components, perform the following steps:


Step 1 Unpack all cosmetic parts to prepare for installation.

Attaching the Rear Vertical Cable Troughs

Before you attach the left and right vertical cable troughs, if the verticals h ave L-brackets, they will need to be removed so that they do not interfere with the air deflector. See Figure 5-12.

Figure 5-12 Removing L-Brackets

 

Step 2 Attach the rear vertical cable troughs—one left and one right—to the rear of the chassis (see Figure 5-13) by i nserting the 10 M4x14-mm pan head screws (five on each side) and using the screwdriver to turn the screws clockwise to attach the cable troughs firmly to the chassis. (You might need to use a ladder to reach the upper screws.)


Note We recommend that you use two people to install the troughs, one person to hold the troughs in place while the other person inserts and tightens the screws.
