8-Slot Line Card Chassis Enhanced Router
Unpacking, Moving, and Securing Guide
This guide provides instructions for unpacking the Cisco CRS 8-Slot Line Card Chassis (LCC) Enhanced router 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 Enhanced Router Site Planning Guide , which describes how to plan and prepare your site facilities for the installation of an 8-slot Cisco CRS 8-Slot Line Card Chassis Enhanced router.
The Cisco CRS 8-slot LCC Enhanced router 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 12.8 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 8-slot LCC Enhanced router has its own power and cooling subsystems. The Cisco CRS 8-slot LCC Enhanced router power subsystem has a 70 Amps breaker. While the Cisco CRS 8-slot LCC Enhanced router power subsystem with the 70 Amps breaker can be installed in a Cisco CRS 8-slot LCC router the legacy power shelf with the 60 Amps breaker from a Cisco CRS 8-slot LCC router CANNOT be inserted to a Cisco CRS 8-slot LCC Enhanced router.
- The Cisco CRS-1 Carrier Routing System uses fabric cards designed for 40 GB operation (FC/S cards).

- 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 Enhanced router 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 Enhanced Router 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.
- To install the chassis in the equipment rack: approximately 40 inches (101.6cm)
- To service components and allow system airflow (both in front of and behind the chassis): 36 inches (91.4 cm)
Caution The Cisco CRS 8-Slot Line Card Chassis Enhanced router with pallet should be handled carefully to eliminate the risk of tipping over the package.
Step 4 Remove the Fan Tray carton, screws and the remaining packing material (as shown in Figure 4). Carefully set them aside.
Step 6 Using two people, lift the box straight up over the chassis as shown in Figure 5.
After performing this task, go to the “Removing the Chassis from the Pallet” section.
Step 1 Using the 10 mm socket wrench, 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 6.)
After you have removed the support brackets that secure the chassis to the pallet, go to the “Removing the Rear Vertical Mounting Brackets” section for instructions on removing the rear vertical mounting brackets from the chassis.
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.
- Phillips #1 screwdriver
- 7-mm hex socket
- 3/4-in. 6-point wrench
- 10 mm socket wrench
- 3/8-in. drive ratchet wrench
- 1/4-in. drive ratchet wrench
Step 1 Use the Phillips #1 screwdriver to remove the seven inside screws on the left and right sides. Save these screws for reuse (refer to Use the 7-mm hex wrench to reattach the rear (MSC) side vertical mounting brackets to the rear of the chassis using the six screws removed earlier. (See Figure 17.)).
Step 2 Use the 7-mm hex socket 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 7.)
After you have removed the rear vertical mounting brackets from the chassis, continue to the “Transferring the Chassis to a Mechanical Lifting Device” section.
This section describes how to put the chassis on the lift and install the horizontal mounting brackets and then transfer the chassis to a lifting device. We recommend that at least two 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.
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 on the side of the chassis on the pallet as shown in Figure 8.
Step 3 With at least two people move the chassis carefully from the pallet onto the lifting device as shown in Figure 9.
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 it may bend or break (see Figure 10).
Figure 10 shows the location of the cable management trough on the PLIM side of the chassis.
- Moving Guidelines for the Cisco CRS 8-Slot Line Card Chassis Enhanced Router
- Moving the Chassis to the Final Location
Note The installation of a Cisco CRS 8-Slot Line Card Chassis Enhanced router 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 Enhanced Router Site Planning Guide.
We recommend that at least two people move the as-shipped chassis from the shipping dock to the installation site. Make sure that you have at least three people to transport the chassis up and down a ramp. 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 Enhanced Router 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.
- 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 Cisco CRS 8-Slot Line Card Chassis Enhanced router. 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 Enhanced router.
For more detailed information about rack requirements for the Cisco CRS 8-Slot Line Card Chassis Enhanced router, see the Equipment Rack Specifications section in Chapter 3 of Cisco CRS Carrier Routing System 8-Slot Line Card Chassis Enhanced Router 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.
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 11.
If you are installing two chassis in a rack, install the upper chassis first (see Figure 13). To install the horizontal mounting rails, follow these steps:
Note If you are not using the Cisco-provided four post rack, order the Install Kit (CRS-8-Install-Kit=). The horizontal mounting brackets are only shipped with the Install kit. Note that while the Install Kit also includes the rear pull handles, these pull handles are not used with the modular power supplies provided with the Cisco CRS 8-Slot Line Card Chassis Enhanced router.
Note Take great care to ensure that both horizontal mounting rails (see Figure 12) 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 above the lower router (ensure your spacing leaves enough height for the second router). Figure 13 shows two Cisco CRS 8-Slot Line Card Chassis Enhanced routers 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 Enhanced Router 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 Enhanced Router Site Planning Guide .
- For specifications on the chassis, see Appendix A, Cisco CRS 8-Slot Line Card Chassis Enhanced Router Specifications , in the Cisco CRS Carrier Routing System 8-Slot Line Card Chassis Enhanced Router Installation Guide .
Caution To avoid tipping the chassis and possible injury when installing 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 14.)
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. If the horizontal mounting brackets were used the chassis should be level.
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 14.
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.
This section describes how to mount the Cisco CRS 8-Slot Line Card Chassis Enhanced router 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 Enhanced Router 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.
Figure 15 shows the chassis mounting hardware ready for rack mounting.
As an example of a suitable lifting device, Figure 16 shows a scissor lift raising the chassis.
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 using the six screws removed earlier. (See Figure 17.)
Step 7 Reinsert the seven (7) inside screws removed in Use the Phillips #1 screwdriver to remove the seven inside screws on the left and right sides. Save these screws for reuse (refer to “Step 6Use the 7-mm hex wrench to reattach the rear (MSC) side vertical mounting brackets to the rear of the chassis using the six screws removed earlier. (See Figure 17.)” task on page 29). (removing the rear vertical brackets).
Step 8 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 18.)
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 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 19.)
After performing this task, you need to unpack the remaining chassis components. See the next section and then go to the Cisco CRS Carrier Routing System 8-Slot Line Card Chassis Enhanced Router 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 Cisco CRS 8-Slot Line Card Chassis Enhanced router is located on the front (PLIM) side between the upper PLIM card slots and cable management bracket. (See Figure 20.)
