Information About Exterior Cosmetic Components
This section contains some general information about the exterior cosmetic components.
The Cisco CRS 16 slot line card chassis is shipped with exterior cosmetic components for the front (PLIM) side and rear (MSC) side of the chassis.
Note |
Some exterior cosmetic components are not required to be installed. |
This figure shows the exterior cosmetics for the front (PLIM) side of a chassis with fixed configuration power shelves installed. The front view of a LCC with modular configuration power shelves installed is similar.

This figure shows the exterior cosmetics on the rear (MSC) side of a LCC, with fixed configuration power shelves installed. The upper air grille and vertical brackets are shipped with the LCC, but are not pre-installed on the system the system. The rear kick panel kit, shown in the figure, is not included as part of the default shipment and is available to be ordered seperately (Cisco product number CRS-16-LCC-BCK-KP). The rear view of a LCC with modular configuration power shelves installed is similar.

Installing the Front (PLIM) Side Cosmetic Components
This section describes how to install the front (PLIM) side exterior cosmetic covers and accessories on the LCC. This Figure shows the exterior cosmetics for the front (PLIM) side of a chassis with fixed configuration power shelves installed. The front view of a LCC with modular configuration power shelves installed is similar.
Note |
While it is possible to install the various exterior components on the LCC in a different order, it is easier to install them in the order outlined in this section. |
This section describes how to perform the following tasks:
-
Attaching the Unistruts
-
Attaching the Upper Grille Support
-
Attaching the Power Shelf Shutoff Extenders (fixed configuration power only)
-
Attaching the Front Vertical Cable Troughs
-
Installing the Cable Pass-through Accessory Plates (Optional)
-
Installing the Upper Grille and Logo Bezel
-
Installing the Lower Grille Screen and Frame Assembly
-
Attaching the Lower Grille
-
Attaching the Front Exterior Doors
Prerequisites
Before performing this task, 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, bit size #1
- 10-mm hex key wrench
- 2-mm hex key wrench (for adjusting door set screws)
- Torque wrench with 10-mm hex key and rated accuracy at 40 to 50 in.-lb (4.52 to 5.65 N-m)
- Unistrut (Cisco product number 800-23375-XX
- Upper grille support and power shelf shutoff extender (AC grille kit; Cisco product number 69-1163-XX, or DC grille kit; Cisco product number 69-1164-XX)
- Lower grille frame assembly (Cisco product number 800-23320-XX, which includes lower grille; Cisco product number 800-23487-XX)
- Vertical cable trough (Cisco product number 69-1199-XX)
- Optional cable pass-through accessory kit
- Logo bezel and support (Cisco product number 800-23488-XX)
- Exterior doors kit (Cisco product number 69-1160-XX)
Steps
To install front (PLIM) side exterior cosmetic components, perform the following tasks:
Attaching the Unistruts
SUMMARY STEPS
- Attach each unistruts to the top of the chassis by inserting twelve M12 hex head bolts and washers, six for each strut, into the bolt holes on the inside of the strut, and tightening with the 10-mm hex key wrench. The closed end of a unistrut faces the front (PLIM) side of the chassis.
- Attach the upper grille support (see previous figure) to the unistruts by inserting four M4x14-mm long flat head screws, two for each unistrut, and tightening them to the unistruts with the screwdriver.
- Attach the power shelf shutoff extenders (fixed configuration power only—number 3 in the previous figure) by inserting the four M4 panhead screws, two for each power shelf shutoff extender, and tightening them with the screwdriver.
- Attach the vertical cable troughs—one right and one left—to the front (PLIM) side of the chassis (as shown in the next figure):
- Remove the blank plates by unscrewing the four screws on each one.
- Attach the inner cut-out panels using the four screws provided.
- Attach the outer cut-out panel using the four screws provided.
- Attach the upper grille (optional) by carefully inserting the tabs on the grille into the hook hanger brackets on the top of the upper grille support (see next figure).
- Press the grille firmly against the grille support until it snaps onto the ball stud snaps.
- Place the logo bezel (see the next figure) over the bezel support, and press firmly until the bezel snaps onto the ball stud snaps.
- Using the screwdriver, loosen the four captive screws, two on each side, that secure the lower grille screen to its frame assembly; then carefully set the screen aside (see the next figure).
- Attach the frame assembly to the chassis as in the previous figure by aligning the four screws, two on each side, on the frame to the screw holes on the chassis and tightening them with the screwdriver.
- Reattach the inlet grille screen (see the previous figure) to the frame assembly by aligning the four captive screws on the screen to the screw holes on the frame assembly and tightening the screws with the screwdriver.
- Attach the lower grille by carefully inserting the tabs on the grille into the hook hanger brackets on the inlet grille frame.
- Press the lower grille firmly until it snaps onto the ball stud snaps.
- Orient the doors so that the keyholes slots are pointing up (see the next figure).
- Align the doors vertically in their appropriate positions so that you can determine where to thread the first two screws that are adjacent to the keyholes. Set the doors aside and thread the two screws.
- Insert four M4x8-mm wafer head screws (two on each side) into the appropriate screw holes in the doors, and use the screwdriver to tighten fully.
- Insert and slightly tighten all screws.
- Ensure that the doors are properly aligned.
