This guide provides instructions for unpacking the Cisco CRS 8-Slot Line Card Chassis (LCC) and its components, moving the chassis to its permanent location, and mounting the chassis in a rack. The companion document to this guide is Cisco CRS Carrier Routing System 8-Slot Line Card Chassis Site Planning Guide , which describes how to plan and prepare your site facilities for the installation of an 8-slot line card chassis.
The Cisco CRS 8-slot LCC is a half-height, rack-mounted 8-slot version of the 16-slot chassis. It is a highly scalable routing system that provides up to 6.4 terabits per second (Tbps) of routing capacity and supports up to 8 MSCs or FPs. The chassis installs in a 19-inch equipment rack.
- Modular services cards (MSCs) or forwarding processors (FP), also called line cards, (up to eight)
- Physical layer interface modules, or PLIMs, also called line cards, (up to eight, one for each MSC or FP) or SIPs/SPAs
- Route processor (RP) cards (up to two) or performance route processor (PRP) cards (up to two)
- Switch fabric cards (four required)
- A chassis midplane that connects MSCs or FPs to their PLIMs and to switch fabric cards
- The Cisco CRS-1 Carrier Routing System uses fabric cards designed for 40 GB operation (FC/S cards).
- The Cisco CRS-3 Carrier Routing System uses fabric cards designed for 140 GB operation (FC-140G/S cards).
- The Cisco CRS-X Carrier Routing System uses fabric cards designed for 200 GB operation (FC-400G/S cards in 200G mode).
Caution A mixture of 40G, 140G, and 200G fabric cards is not a supported mode of operation. Such a mode is allowed temporarily only during the upgrade process.

The Cisco CRS 8-slot line card chassis arrives packaged on several pallets (the number of pallets depends on the options you ordered) with each package containing a label that describes the contents. For complete details on the contents of your shipment, see the inventory and parts identification label on the crate as shown in Figure 1. The total number of pallets depend on the details of the options you ordered with each package containing a label that describes the contents.
Note Crate numbering for chassis packaging is for reference only. This list is only a sample of what a CRS 8-slot chassis shipment contains. For complete details on the contents of each pallet, see the shipping and parts identification label on the pallet or shipping manifest.
The chassis is shipped with the air filter already installed. The modular services card (MSC) and physical layer interface module (PLIM) slots are populated with blanks and impedance carriers. The switch fabric slot is shipped with a slot cover over it.
- Card pallet (Crate 2): Contains the route processors (RP) or performance route processor (PRP) cards , rectifier, fixed power entry module (PEM), modular power module (PM), switch fabric cards, the MSCs, and any PLIMs.
- Primary card pallet (Crate 3): shipped only if the system is configured with 2-4 line cards and 2-4 PLIMs)
- Card pallet (Crate 4): shipped only if the system is configured with 5-8 line cards and PLIMs)
- Accessory kit:
The Cisco CRS 8-Slot line card chassis is shipped in a double-wall carton on a standard shipping pallet. Always transport the chassis in its original packaging and make sure that the system is transported and stored in an upright position. If you plan to store system components before the installation, be sure to store the components carefully and in their original shipping containers to prevent accidental damage.
- 418.3 lb. (189.7 kg) chassis with shipping crate and pallet
- 330.8 lb. (138 kg) chassis with fans, PDUs, blanks, and impedance carriers (as shipped)
- Pallet length: 48 in. (121.3 cm)
- Pallet width: 37.12 in. (94.3 cm)
- Pallet height: 10.5 in. (26.6 cm)
- Shipping carton height: 50.87 in. (129.2 cm)
- Keep the work area clear and dust-free during and after installation. Do not allow dirt or debris to enter into any laser-based components.
- Do not wear loose clothing, jewelry, or other items that could get caught in the router while working with MSCs, FPs, PLIMs, or their associated components.
- Cisco equipment operates safely when used in accordance with its specifications and product-usage instructions.
- Be sure to power down a fixed configuration PDU or modular configuration power shelf before removing it from the chassis.
- Do not work alone if potentially hazardous conditions exist.
The floor plan for the Cisco CRS 8-slot line card chassis must include enough space to install the chassis in the equipment rack and allow sufficient airflow for the system. The floor plan must also provide enough room to access chassis components for maintenance (for example, to remove fan trays, power modules, cables, and air filters).
For chassis installation, make sure that enough room exists in front of the chassis to accommodate installation personnel and the lifting device used to hold the chassis in the rack while it is bolted to the rack.
Figure 2 shows the service area flooring in a lab from the top of the chassis.
For details on making your site ready for the chassis, see Cisco CRS Carrier Routing System 8-Slot Line Card Chassis Site Planning Guide.
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. We recommend to use an ESD-preventive strap whenever you handle network equipment or one of its components.
- Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact. Connect the equipment end of the connection cord to an ESD connection socket on the router or to a bare metal surface on the chassis.
- Handle a card by its ejector levers, when applicable, or the card's metal carrier only; avoid touching the board or connector pins.
- Place a card removed from the chassis, component side up, on an antistatic surface or in a static-shielding bag. If you plan to return the component to the factory, immediately place it in a static-shielding bag.
- Avoid contact between the card and clothing. The wrist strap protects the board only from ESD voltage on the body; ESD voltage on clothing can still cause damage.
Caution Use the complete Cisco Systems packaging for shipment of product or components. Failure to properly use Cisco packaging may result in damage or loss of the product.
Before performing this task, be sure to have sufficient room around the chassis pallet for unpacking. For information about the chassis dimensions, see Appendix A, Cisco CRS 8-Slot Line Card Chassis Specifications in Cisco CRS Carrier Routing System 8-Slot Line Card Chassis Installation Guide .
Caution The 8-slot line card chassis with pallet should be handled carefully to eliminate the risk of tipping over the package.
Step 3 Remove the accessory carton and remaining packing material (as shown in Figure 4). Carefully set them aside.
Step 4 Using two people, lift the box straight up over the chassis as shown in Figure 5.
This section describes how to install the rear pull handles (for fixed configurations only). The rear pull handles provide additional handholds to aid you in moving the chassis, mounting the chassis into a rack, and unmounting the chassis. (See Figure 6)
Step 3 Using the 10-mm hex wrench, remove the front two screws that fasten the top of the left PDU (as you face the rear (MSC) side of the chassis) to the PDU holding plate. Leave the rear two screws and PDU holding plate in place.
Step 5 Hold one rear pull handle in place over the left PDU (as you face the rear of the chassis). Starting with the top two screws, hand tighten the four screws that hold the pull handle to the chassis-PDU combination. Figure 7 shows the Cisco CRS 8-slot chassis with rear pull handles installed.
This procedure describes how to remove the support brackets that secure the chassis to the pallet and then transfer the chassis to a lifting device. We recommend that at least two or three people perform this procedure.
Caution Exercise extreme caution during this procedure. The chassis is unstable when not secured to the pallet or rack. The chassis should always remain upright and should not be bumped or dropped.
Step 1 Using a screwdriver, remove the six panhead M5 x10-mm screws (three screws at the bottom of the bracket and three at the top) that connect the right-front support bracket to the chassis. (See Figure 8.)
Caution Because of the high chassis weight (with fans, PDUs, blanks, and impedance carriers as shipped), you should not attempt to move or lift it without a mechanical lifting device.
Step 1 Place the mechanical lifting device in front of the chassis on the pallet (PLIM side) as shown in Figure 9.
Step 3 With at least two or three people move the chassis carefully from the pallet onto the lifting device as shown in Figure 10.
Note Other resources might be required to ensure a safe chassis transfer. We recommend using as many people as required to move the chassis at your site safely. Always follow safety precautions when moving a chassis.
Caution When moving or mounting the chassis, be careful not to apply pressure to the horizontal cable management trough on the front PLIM side of the chassis, or they may bend or break (see Figure 11).
Figure 11 shows the location of the cable management trough on the PLIM side of the chassis.
Note The installation of a Cisco CRS 8-Slot line card chassis may require space, floor loading, power, and cooling modifications to your facility. Site planning should have been performed well in advance of the scheduled delivery of your system. See the Cisco CRS Carrier Routing System 8-Slot Line Card Chassis Site Planning Guide.
We recommend that at least two or three people move the as-shipped chassis from the shipping dock to the installation site. We also recommend that you leave the as-shipped chassis attached to its pallet for moving. Follow these guidelines:
- Chassis installation location must be identified.
- Packaging should be removed while leaving the chassis firmly secured to the pallet.
Note To ensure that the chassis has proper access to the installation location, see Cisco CRS Carrier Routing System 8-Slot Line Card Chassis Site Planning Guide.
- Identify the type of suitable moving device that will be used to move the as-shipped chassis from the loading dock or staging area to the installation site.
- Make certain all doorways and hallways are wide and tall enough for the moving the as-shipped chassis. The 8-slot chassis needs an aisle of approximately 60 inches in width to be turned while on a fork lift.
- Make sure that you have at least one person on each side of the chassis.
- When transporting the as-shipped chassis on a ramp , follow these guidelines:
Caution If the route to the installation site has any ramps, use a moving device other than a scissor lift to move the chassis over the ramps, and then transfer the chassis onto a suitable lifting device such as a scissor lift for installation. Leave the blanks and impedance carriers in place in empty card slots while you move or install the chassis in the rack. The blanks and impedance carriers provide support to keep the chassis square during movement and installation.
This section describes how to move the as-shipped 8-slot line card chassis. The 8-slot chassis is shipped preinstalled with four vertical rack mounting rails for installing the chassis. For stability and support, leave the mounting brackets installed when you move the chassis.
Caution The chassis is shipped with blanks and impedance carriers installed or slot covers installed over all slots. Leave these in place to maintain chassis stiffness and integrity during moving.
Step 1 Make sure you have a suitable lifting device to move the Cisco CRS 8-Slot Line Card Chassis.
For more detailed information about rack requirements for the Cisco CRS 8-Slot line card chassis, see the Equipment Rack Specifications section in Chapter 3 of Cisco CRS Carrier Routing System 8-Slot Line Card Chassis Site Planning Guide .
Warning The chassis should be mounted on a rack that is permanently affixed to the building. Statement 1049
To bolt the rack to the floor, a floor bolt kit (also called an anchor embedment kit ) is required. For information on bolting the rack to the floor, consult a company that specializes in floor mounting kits (such as Hilti; see Hilti.com for details). Make sure that floor mounting bolts are accessible, especially if annual retorquing of bolts is required.
Remove the rear vertical mounting brackets temporarily because the chassis, with the rear vertical mounting brackets attached, cannot be installed into the rack from the front. The chassis must be positioned into the rack. Reattach them after the chassis has been positioned into the rack with the original mounting hardware.
Caution On the MSC side, blanks and impedance carriers need to be removed to remove rack mounting brackets. After the chassis and the mounting bracket are installed, the blanks and impedance carriers should be re-installed.
Step 2 Use the 7-mm hex wrench to remove the outside screws (six for each bracket and one hidden screw) that hold the rear side chassis vertical mounting brackets (right side bracket and left side bracket) to the chassis. (See Figure 12.)
Caution When the vertical mounting brackets are removed, be careful not to handle the chassis by the side panels to avoid bending them.
If you are installing a single chassis in a rack, the chassis must go in the middle or bottom portion of the rack or follow your company chassis mounting practices, as shown in Figure 14.
If you are installing two chassis in a rack, install the upper chassis first (see Figure 16). To install the horizontal mounting rails, follow these steps:
Note Take great care to ensure that both horizontal mounting rails (see Figure 15) are perfectly level and at the same height in the rack.
Step 6 If you are mounting two chassis in a single rack, attach two additional horizontal mounting rails to the top of the rack, parallel to the attached horizontal mounting rails (to maintain a proper depth spacing of 22.8 inches for the chassis on the rack). Figure 16 shows two Cisco CRS 8-Slot chassis mounted in one equipment rack.
Before you mount the 8-slot chassis into a rack, it is critical that the installation site be prepared properly to handle the chassis weight, power requirements, cooling needs, and other requirements.
Because a fully-configured chassis weight can be up to 650 lb (294.84 kg), you should review the rack specifications from the manufacturer to determine whether the racks you have are appropriate to handle the weight of the chassis. See the “Equipment Rack Specifications” section in Chapter 3 of Cisco CRS Carrier Routing System 8-Slot Line Card Chassis Site Planning Guide .
- For complete details on site preparation and details about racks and any preparations you need to make at your site for mounting the chassis, see the Cisco Carrier Routing System 8-Slot Line Card Chassis Site Planning Guide .
- For specifications on the chassis, see Appendix A, Cisco CRS 8-Slot Line Card Chassis Specifications , in the Cisco CRS Carrier Routing System 8-Slot Line Card Chassis Installation Guide .
Caution To avoid tipping the chassis and possible injury when installing or servicing it, take care to properly position the chassis in the rack when you are mounting it.
To accommodate equipment racks with different mounting hole patterns, the chassis mounting brackets have groups of screw holes on either side. (See Figure 17.)
The mounting holes in the chassis mounting brackets are spaced so that one mounting hole in each hole group aligns with a corresponding hole in the equipment rack or the optional center-mount bracket. By using the corresponding mounting hole (in the same hole group) on the opposite side of the chassis, you can level the chassis in the rack.
To accommodate different site requirements, the chassis can be mounted in a rack with either the front (PLIM) side or rear (MSC) side facing out. We recommend that the chassis be mounted with the front side facing out as shown in Figure 17.
Caution When you are installing the chassis in a rack, leave the PLIM impedance carriers in place to provide the chassis with enough support to keep it square during the procedure. However, the MSC impedance carriers should not be replaced until the chassis installation is complete.
This section describes how to mount the Cisco CRS Carrier Routing System 8-Slot Line Card Chassis into a standard 19-inch rack with the front (PLIM) side of the chassis facing out (in other words, by sliding the rear (MSC) side of the chassis into the rack first). Use only a four-post rack that matches the mounting specifications required for the chassis.
For more detailed information about rack types and preparations required for mounting the chassis at your site, see the information in Cisco CRS Carrier Routing System 8-Slot Line Card Chassis Site Planning Guide .
Caution On the PLIM side, no components should be removed at any time unless it is installed in a rack and is to be replaced by a functioning PLIM.
Caution On the MSC side, blanks and impedance carriers need to be removed to remove rack mounting brackets. After the chassis and the mounting bracket are installed, the blanks and impedance carriers should be re-installed.
Figure 18 shows the chassis mounting hardware ready for rack mounting.
- Suitable transport device
- Phillips #1 screwdriver, 6-in. long and 8-in. long
- 10-mm and 7-mm hex wrench
- Mechanical lifting device, such as a scissor lift or other suitable lifting device
- Installation kit, shipped with the chassis, (contains horizontal mounting brackets and screws) (Cisco product number CRS-8-INSTALL-KIT=)
As an example of a suitable lifting device, Figure 19 shows a scissor lift raising the chassis.
a. For a fixed configuration, stand behind the chassis, use the rear pull handles (only with a fixed configuration) to carefully move the chassis from the mechanical lift aid to the rack, and slide it onto the horizontal mounting rails of the rack.
Step 5 Use the front pull handle to push carefully until the front vertical mounting brackets contact the rack mounting bracket with the vertical rack posts and someone in the rear guiding the chassis into the rack.
Step 6 Use the 7-mm hex wrench to reattach the rear (MSC) side vertical mounting brackets to the rear of the chassis. (See Figure 20.)
Step 7 Insert and partially tighten the 48 screws —12 on each edge—to attach the chassis vertical mounting brackets to the rack vertical mounting brackets. (See Figure 21.)
Note To accommodate equipment racks with different mounting-hole patterns, the chassis vertical mounting brackets have groups of screw holes on either side. The mounting holes in these rails are spaced so that one hole in each hole group aligns with a hole in the equipment rack or the optional center-mount bracket. Use the corresponding mounting hole (in the same hole group) on the opposite side of the chassis to level the chassis in the rack.
This section describes how to remove the rear pull handles for fixed configurations only. The pull handles provide additional handholds to aid you in moving, mounting, and unmounting the chassis. (See Figure 22.)
This section describes how to remove the front pull handle. The pull handle provides additional handholds to aid you in moving, mounting, and unmounting the chassis and is installed on the chassis when it is shipped. (See Figure 23.)
After performing this task, you need to unpack remaining chassis components. See the next section and then go to the Cisco CRS Carrier Routing System 8-Slot Line Card Chassis Installation Guide to locate the installation instructions for the individual components.
Before preparing to return the product or product components, you must contact Cisco technical support and provide them with the details of your difficulty. Technical support needs to confirm your product or component failure before assigning an RMA number for return shipment. For additional information, see the “Obtaining Documentation and Submitting a Service Request” section.
To facilitate your conversation with technical support, locate and note the serial number of your chassis. The serial number label for the line card chassis is located on the front (PLIM) side between the upper PLIM card slots and cable management bracket. (See Figure 24.)
