Chassis Packaging Overview
The FCC arrives packaged on several pallets (total depends on the details of the options you ordered) with each package containing a label that describes the contents:
•Installation kit (crate 1): contains the drill template and other installation kit items.
•Chassis pallet (crate 2): contains the chassis itself encased in a polyethylene bag and covered with a wooden packing crate held together with metal clips (CRS-FCC=). The chassis is shipped with the fan trays (CRS-FCC-FAN-TR) air filter (CRS-FCC-FILTER) already installed. The switch fabric card (SFC) slots are populated with impedance carriers (CRS-SFC-IMPEDANCE=) or covered by slot covers.
•Power components pallet (crate 3): contains the power components, including the power shelves (CRS-FCC-PS-ACD=, CRS-FCC-PS-ACW=, or CRS-FCC-PS-DC=), power modules (CRS-16-DC-PEM= or CRS-16-AC-RECT=), alarm module (CRS-16-ALARM=), and power cosmetic bezel and retainer frame.
•Card pallet (crate 4): contains the SFCs (CRS-FCC-SFC=) and shelf controller Gigabit Ethernet (SCGE) cards (CRS-FCC-SCGE= or SC-GE-22=).
•Cosmetics pallet (crate 5—this option is orderable): contains the exterior (cosmetic) components for the chassis (CRS-FCC-FRNT-CM= and CRS-FCC-REAR-CM=).
For complete details on the contents of each pallet, see the shipping and parts identification label on the pallet or shipping manifest.

Dolly Specifications
The dolly that is available for the FCC is flexible enough to meet several difficult challenges common when first positioning a chassis of this size and weight.
Note The dolly is shipped with the line card chassis (LCC). See Installing a Cisco CRS-1 Series Carrier Routing System 16-Slot Line Card Chassis for packaging details.
The challenges include limited hallway or doorway width, doorway thresholds, ramps, and tight corners along the transport route. To overcome these challenges, you can use the dolly in either of two configurations:
•90-degree configuration: The dolly assemblies are shipped in this configuration. Although this configuration is not recommended when moving the chassis, in certain cases this configuration is needed to transport the dolly. Extra care should be used in this configuration to ensure that the chassis does not tip during transport.
•180-degree configuration: This configuration provides wider support in the dolly and is the recommended configuration for transporting the chassis. However, this configuration requires a minimum of 50 inches of side clearance along the transport route.
Note The dolly ships in the 90-degree configuration (Figure 1). When manipulating the individual dolly components, such as when they are not attached to the chassis, the dolly is easiest to use in the shipped 90-degree position.
Table 3 lists the specifications for the dolly.

Safety Guidelines
Before you perform any procedure in this document, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment.
The following guidelines are for your safety and to protect equipment. The guidelines do not include all hazards. Be alert.
Note Review the safety warnings listed in Regulatory Compliance and Safety Information for the Cisco CRS-1 Carrier Routing System before installing, configuring, or troubleshooting any installed card.
•Never attempt to lift an object that might be too heavy for you to lift by yourself.
•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.
•Keep tools and router components away from walk areas.
•Do not wear loose clothing, jewelry, and other items that could get caught in the router while working with OIMs, SFCs, and their associated components.
•Use Cisco equipment in accordance with its specifications and product-usage instructions.
•Do not work alone if potentially hazardous conditions exist.
•Make sure that your installation follows national and local electrical codes: in the United States, National Fire Protection Association (NFPA) 70, United States National Electrical Code; in Canada, Canadian Electrical Code, part I, CSA C22.1; in other countries, International Electrotechnical Commission (IEC) 60364, part 1 through part 7.
•Connect only a DC power source that follows the safety extra-low voltage (SELV) requirements in UL/CSA/IEC/EN 60950-1 and AS/NZS 60950 to the FCC DC-input power system.
•Make sure that you have a readily accessible two-poled disconnect device incorporated in the fixed wiring of an FCC configured with the DC-input power system.
•The FCC requires short-circuit (overcurrent) protection to be provided as part of the building installation.
Preventing Electrostatic Discharge
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. We recommend use of an ESD-preventive strap whenever you handle network equipment or one of its components.
Following are guidelines for preventing ESD damage:
•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 its metal carrier only; avoid touching the board or connector pins.
•Place a removed card board 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 from only ESD voltage on the body; ESD voltage on clothing can still cause damage.

Required Tools and Equipment
You need the following tools to perform this task:
•9/16-inch wrench
•5/8-inch wrench
Steps
To unpack the dolly, follow these steps:
Step 1 Carefully move the pallet containing the dolly to the location where you plan on unpacking it. The dolly arrives as two separate, identical components, one component each for the front and back of the chassis.
Caution Make sure that the dolly caster brakes and antirotation pins are in the locked position before removing the dolly from the crate.
Step 2 Use the 9/16-in. wrench to unbolt the crate sides from the pallet base, remove the sides, and set them carefully aside.
Step 3 Release the caster brakes on the dolly.
Step 4 Use the 5/8-inch wrench to unbolt the two side plates, and remove the side plates.
Step 5 Remove the two dolly components from the pallet.
Caution Each dolly component weighs approximately 126 lb (57 kg). It is safer to use two people to remove the components from the pallet rather than a single person.
What to Do Next
After performing this task, unpack the chassis. See the "Unpacking the Chassis" section for more information.
Unpacking the Chassis
This section describes how to unpack the FCC.
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 product.
The chassis is shipped on a pallet by itself and arrives inside a polyethylene bag enclosed in a plywood box, held in place by steel clips (see Figure 2).

Prerequisites
Before performing this task, be sure to have sufficient room around the chassis pallet for unpacking.
Required Tools and Equipment
No tools and equipment are required for this task.
Steps
To unpack the chassis, follow these steps:
Step 1 Carefully move the pallet containing the FCC to the location where you plan on unpacking it.
Note A dolly is shipped with the line card chassis (LCC) and can be used to move the chassis into place; however, you are not required to move the chassis into place before unpacking it. See Installing a Cisco CRS-1 Series Carrier Routing System 16-Slot Line Card Chassis for packaging details.
Caution The FCC weighs 780 lb (323 kg) when shipped (with fan trays and impedance carriers installed), is 80.0 in. (203 cm) tall, and should be handled carefully to eliminate the risk of tipping the chassis over. We recommend using at least two people to handle and move the chassis.
Step 2 Raise and twist the lock latches along the sides and base of the plywood box.
Step 3 Remove the large side panel, and set it carefully aside.
Step 4 Remove the remaining four-sided plywood box.
Note When setting aside the box, be careful to rest the wood on the floor so that the metal lock latches are not bent or otherwise damaged.
Note Two people have to lift and remove the four-panel unit.
Step 5 Remove the chassis bag. A set of tape seals exists around the perimeter of the chassis base. Unseal the bag, and pull it off the chassis.
Note Do not remove the plastic bag until you are ready to move and install the chassis.
What to Do Next
After performing this task, you must attach the dolly to the chassis (see the "Attaching the Dolly to the Chassis" section).
Attaching the Dolly to the Chassis
This section describes how to attach the dolly (see Figure 3) to the FCC to prepare for removing the chassis shipping pallet and moving the chassis into place.
Note The dolly is shipped with the LCC and has the LCC clamp plates installed (see Figure 3). See Installing a Cisco CRS-1 Series Carrier Routing System 16-Slot Line Card Chassis for packaging details.

Step 14 Relock the caster brakes.
Step 15 Repeat steps 11 through 14 to attach the second dolly component to the rear (OIM) side of the chassis.
What to Do Next
After performing this task, remove the shipping pallet from the chassis. See the "Removing the Chassis Shipping Pallet" section for more information.
Removing the Chassis Shipping Pallet
This section describes how to remove the shipping pallet to prepare for moving the FCC into place.
Prerequisites
Before performing this task, unpack the chassis, unpack the dolly, and attach the dolly to the chassis. See the "Unpacking the Chassis" section, the "Unpacking the Dolly" section, and the "Attaching the Dolly to the Chassis" section for more information.
Required Tools and Equipment
No tools and equipment are required for this task.
Steps
To remove the shipping pallet from the chassis, follow these steps:
Step 1 Make sure that the dolly is firmly attached to the chassis.
Step 2 Make sure that the dolly caster brakes and antirotation pins are in the locked position.
Step 3 Using two people (one person working on each dolly component), crank the two crank handles to lift the chassis up about 3/4 of an inch above the pallet.
Note See the raising or lowering the chassis guidelines in the "Dolly and Chassis Moving Guidelines" section.
Step 4 Slide the pallet from the chassis.
Note The two outrigger legs must be in the 90-degree position (see Figure 3) in which they are aligned to the front and back of the chassis when sliding the pallet from the chassis.
Step 5 Using two people (one person working on each dolly component), lower the chassis to within 1 inch of the floor. See the height label on the dolly lift wheel assembly.
Warning To reduce the risk of dolly instability, chassis damage, or personal injury, do not raise the equipment more than 1 inch (2.54 cm) above the floor during transportation. Statement 358
What to Do Next
After performing this task, you may unpack the other pallets and move the chassis. See the "Unpacking the Other Pallets" section and the "Moving the Chassis" section.
Unpacking the Other Pallets
This section describes how to unpack the primary, secondary, power, and cosmetic pallets for the FCC.
Prerequisites
No prerequisites exist for this task.
Required Tools and Equipment
You need the following tools to perform this task:
•Antistatic mat
•Medium Phillips screwdriver
•Scissors
Steps
To unpack the pallets, follow these steps:
Step 1 If possible, move the pallets to the same location as the unpacked and secured chassis. If not possible, move the individual boxes containing the various components to the chassis location.
Note All components are packaged separately. Cards are attached and installed on a wooden board insert held in place by captive Phillips screws.
Step 2 Use the scissors to cut the straps that hold the packages to the pallet.
Step 3 Unpack all primary pallet parts from the packaging, and set the parts carefully aside on the antistatic mat for installation.
Note We recommend that you unpack and install components in only a sterile environment or clean room. If this is not practical, be sure to take appropriate precautions for the sensitive optical components that are shipped with the chassis.
Step 4 Unpack all secondary pallet parts from the packaging, and set the parts carefully aside on the antistatic mat for installation.
Caution Use the slide-assistance arm to slide cards from the card carrier.
Do not lift cards by the slide-assistance arm! Rotate cards onto their vertical axes, then lift them from the bottom, using the slide-assistance arm only as an aid for balance.
Caution Optical components for some cards are packed in clean room bags; do not open them until you are ready to use them.
Step 5 Unpack all power components from the packaging, and set the components carefully aside on an electrostatic discharge (ESD)-immune surface for installation.
Step 6 Unpack all cosmetic parts from the packaging, and set the parts carefully aside on an ESD-immune surface for installation.
Note If any parts need to be returned, they must be returned in their complete original packaging. Failure to do so may result in damage or loss of product.
Note If you did not order a fully populated system, you received a number of impedance carrier cards that you need to insert into the chassis in the appropriate locations. All slots in the chassis must be populated for the chassis to function properly.
What to Do Next
After performing this task, you may move the chassis (see the "Moving the Chassis" section).
Moving the Chassis
This section presents the following topics:
•Dolly and Chassis Moving Guidelines
•Verifying the Move Path
•Verifying the Securing Location
•Modifying the Dolly Configuration to Move the Chassis
•Moving the Chassis
Dolly and Chassis Moving Guidelines
When you use the dolly or move the FCC, follow these guidelines:
•When using the dolly to move the chassis, you should make sure that the chassis is empty of components.
•When removing the chassis from the pallet, follow these guidelines:
–The dolly must be in the as-shipped 90-degree configuration.
–The caster brakes and antirotation pin should be in the locked position.
–The dolly can be raised to a height of 9 inches for removing the pallet from the chassis.
•When raising or lowering the chassis, follow these guidelines:
–Make sure that you have at least one person on each side of the chassis to turn the cranks on the dolly as simultaneously as possible.
–Raise or lower the chassis only on a level surface.
–Make sure that the caster brakes and antirotation pins are in the locked position.
–Keep the casters on the floor at all times when you are raising or lowering the chassis.
–Attempt to keep the chassis itself as level as possible when raising or lowering it with the dolly.
–Use the height label on the dolly to make sure that you have the correct amount of ground clearance. (The label shows the recommended transport chassis engagement height, the height that is not to be exceeded, and to ensure correct alignment between both dolly wheel assemblies.)
•When changing the configuration of the dolly wheel assemblies (from 180 to 90 or conversely), follow these guidelines:
–Lower the chassis to the floor before you change configurations.
–Keep the casters on the floor at all times when you are changing the dolly configuration from one position to the other.
–Unlock the brake or antirotation on the casters only when you are ready to actually change the configuration (move the lift swing arm bracket). When you are preparing to change the configuration (remove bolts), make sure that the brakes and antirotation pin are in the locked position.
–Change the dolly configuration one caster at a time. Take your time and do not rush through the process.
–Make sure that the bolts are secured after you have completed changing the configuration.
•When moving the chassis in a hallway, follow these guidelines:
–Make sure that you have at least two people to transport the chassis. Never transport the chassis by yourself.
–Make sure that all slots in the chassis are empty before you move it.
–Remove fan trays and power shelves before you move the chassis to avoid top-heavy configuration.
–Use the dolly in the 180-degree configuration whenever possible when you move the chassis. This configuration requires you to have passageways at least 50 inches in width to accommodate the combined dolly and chassis width.
–Use the dolly in the 90-degree configuration if your site restrictions require it. If hallway constraints require you to use the 90-degree dolly configuration (24 inches), the chassis is more likely to tip, so use extra care when transporting the chassis in that configuration.
–The dolly can be used to transport the chassis at heights from 0.5 to 3.0 inches; we recommend raising the dolly to the minimum necessary height based on your site needs.
–The dolly can be used to transport the chassis over thresholds up to 1.5 inches.
•When transporting the chassis on a ramp, follow these guidelines:
–Make sure that you have at least four people to transport the chassis, one person on each side of the chassis, to move it up or down a ramp.
–Move the chassis with the dolly only when all slots inside the chassis are empty.
–Remove fan trays and power shelves before you move the chassis to avoid top-heavy configuration.
–Move the chassis up ramps with a maximum ramp angle of 10 degrees.
–Transport the chassis over thresholds higher than 1 inch only with ramps.
–Use the 180-degree configuration if you transport the chassis up or down a ramp. (The ramp must be wide enough to accommodate the dolly width of 50 inches.) We do not recommend transporting the chassis up or down ramps in the 90-degree configuration.
Warning This dolly is designed only for the temporary transportation of the Cisco equipment listed here. Do not use it with any other device or for any other purpose. Cisco equipment designed for use with the dolly: Cisco CRS-1 fabric card chassis and line card chassis (CRS-FCC, CRS-16-LCC). Statement 356
Warning Do not permanently locate the equipment on the dolly. Safely store the dolly after use. Statement 357
Warning To reduce the risk of dolly instability, chassis damage, or personal injury, do not raise the equipment more than 1 inch (2.54 cm) above the floor during transportation. Statement 358
Warning This dolly is designed to transport the equipment over short distances only. Statement 359
Warning To reduce the risk of chassis damage or personal injury, use the dolly to move the chassis only when the chassis is empty. Before attaching the dolly, remove all components (power shelves, power modules, fan trays, cards, and other modules) from the chassis. Statement 367
Warning To reduce the risk of dolly instability, chassis damage, or personal injury, do not transport the equipment with the dolly raised higher than the maximum transport height shown on the dolly label, and do not raise the equipment higher than required to remove the shipping pallet. For information about maximum dolly heights, see the dolly instructions in this document. Statement 368
Note For a consolidated list of dolly and chassis cautions and warnings, see Regulatory Compliance and Safety Information for the Cisco CRS-1 Carrier Routing System.
Caution Dolly wheel casters and anti-rotation pins should be in the locked position when the dolly is not in use.
Verifying the Move Path
Before moving the chassis, it is critical that you verify that the path that you are planning to use to move the chassis to its final location can accommodate the chassis size and weight and the restrictions of the chassis when using the dolly (see the "Dolly Specifications" section).
See Table 4 for a list of the restrictions for your move path, and verify that you have sufficient room for the entire move path prior to moving the chassis.

Note Allow a gap of between 4 in. to 6 in. (10 cm to 15 cm) on each side of the chassis when moving it.
Verifying the Securing Location
The chassis requires that you have a reasonable amount of space both in front and behind the chassis for sufficient airflow and the installation and removal of components. Allowing the recommended space also ensures that you have enough space available to perform the initial installation of the chassis and its components. Figure 7 shows a typical site floor plan.
Figure 7 Fabric Card Chassis Floor Plan
Before moving the chassis into position, make sure that you have properly prepared the site so that there is sufficient room for installation and maintenance.
For additional details on making your site ready for the chassis, see Cisco CRS-1 Carrier Routing System Fabric Card Chassis Site Planning Guide and Cisco CRS-1 Carrier Routing System Multishelf System Site Planning Guide.
Modifying the Dolly Configuration to Move the Chassis
This section describes how to modify the dolly from one configuration to another if your site requires it. The dolly can be configured in either the 180- or 90-degree position, depending on the needs of your site. For further information on the two configurations, see the "Dolly Specifications" section. See the "Dolly and Chassis Moving Guidelines" section section for important recommendations before modifying the dolly configuration.
The dolly arrives in the 90-degree configuration, shown in Figure 8. (Figure 8 shows the dolly with the LCC clamp plates installed.)

Step 8 Lock the dolly caster brakes and antirotation pins until you are ready to move the chassis.
Step 9 Repeat steps 1 through 8 for the other dolly component.
Step 10 Using the wrench, firmly tighten the holding bolts.
Note To change the configuration back to the 90-degree configuration, repeat these steps and swing the arm into the 90-degree position.
What to Do Next
After the dolly is in the correct configuration for your transport needs, you can move the chassis (see the "Moving the Chassis" section for more information). See the "Dolly and Chassis Moving Guidelines" section for important recommendations before moving the chassis.
Moving the Chassis
This section describes how to move the unpacked FCC.
Note The chassis is shipped with impedance carriers installed in the SFC slots and the card cages covered by cover plates. We recommend leaving these carriers and covers in place to maintain chassis stiffness and integrity during moving.
Note The chassis needs an aisle of approximately 60 inches in width to be turned while on the dolly.
Prerequisites
Before performing this task, unpack the chassis, unpack the dolly, attach the dolly to the chassis, remove the pallet from the chassis, and modify the dolly configuration (if necessary). See the "Unpacking the Chassis" section, the "Unpacking the Dolly" section, the "Attaching the Dolly to the Chassis" section, the "Removing the Chassis Shipping Pallet" section, and the "Modifying the Dolly Configuration to Move the Chassis" section for more information.
Required Tools and Equipment
You need the following parts to perform this task:
•Dolly (Cisco product number CRS-16-LIFT/B=)
•FCC dolly-to-chassis clamp plates (Cisco product number CRS-FCC-LIFT-BRKT=)
Steps
To move the unpacked chassis, follow these steps:
Step 1 Make sure that the dolly is firmly attached to the chassis and that the dolly brakes are in the locked position.
Step 2 With a person on each side of the chassis, turn all four cranks of the dolly slowly clockwise. Lift the dolly to the "Transport" marking on the height label on each lift assembly leg. The dolly can be used to transport the chassis at heights from 0.5 to 3.0 inches; we recommend raising the dolly to the minimum necessary height based on your site needs.
Note The dolly has four separate cranks, each of which works independently. It is best for you to turn each crank as simultaneously as possible when lifting the chassis to keep the chassis as level as possible to prevent undue stress on the chassis frame or dolly and reduce the risk of tipping.
Caution The FCC weighs 780 lb (323 kg) when shipped (with fan trays and impedance carriers installed), is 80.0 in. (203 cm) tall, and should be handled carefully to eliminate the risk of tipping the chassis over. We recommend that you use at least two people to handle and move the chassis.
Note The 180-degree position is the recommended configuration for moving the chassis. If needed because of site requirements, you can rotate the outrigger legs of the dolly to the 90-degree position. See the "Modifying the Dolly Configuration to Move the Chassis" section for further information.
Note You must lower the chassis completely to the floor before rotating the outrigger legs to minimize the risk of tipping. When you have rotated the outrigger legs, you may raise the chassis again. See the "Modifying the Dolly Configuration to Move the Chassis" section for further information.
Step 3 With a person on each side of the chassis, grasp the chassis handles firmly.
Note It is best to use only the chassis handles when you move the chassis into position.
Step 4 Unlock the dolly caster antirotation and brake systems.
Step 5 Roll the chassis carefully into position.
Note The dolly is optimized to move the chassis on flat surfaces. It is not designed to move the chassis up stairs, over curbs, up ramps greater than 10 degrees, or over bumps more than 1.5 inches high (such as door thresholds).
What to Do Next
After performing this task, secure the chassis. See the "Securing the Chassis" section for more information.
Warning Do not permanently locate the equipment on the dolly. Safely store the dolly after use. Statement 357
Securing the Chassis
This section presents the following topics:
•Site Preparation
•Bolt Hole Templates
•Securing the Chassis
•Installing the Inrigger Kit
Site Preparation
Before moving the chassis into place and securing it, you must make sure that your site is prepared. Because of its size, weight, and EMI issues, the chassis must be securely bolted to the floor. Several possible bolting configurations exist for the chassis, including using the optional inrigger kit. Bolt hole templates are provided for the various securing options.
For complete details on preparing your site for the chassis, see Cisco CRS-1 Carrier Routing System Fabric Card Chassis Site Planning Guide.
Bolt Hole Templates
Cisco provides two bolt hole layout templates to help you determine where to install the system:
•An aluminum plate template (CRS-LCC-DRILLTEMP) shows the chassis footprint and the pattern of holes that must be drilled into the floor for the mounting brackets that secure the chassis to the floor.
•A mylar template (CRS-LCC-FLOORTEMP) shows the chassis footprint, door swings, and required clearances to remove and replace chassis components. You can use this template to plan the aisle space required for the installation and maintenance of a line card chassis.
Complete information about the templates and floor plans, clearance information, and planning for future space needs, is included in Cisco CRS-1 Carrier Routing System Fabric Card Chassis Site Planning Guide.
Securing the Chassis
This section describes how to secure the FCC to a concrete floor. The chassis is shipped with a bolt hole template to assist you in putting the bolts in the proper positions on the floor.
The instructions in this section are specific to securing the chassis to a concrete floor. The instructions for securing the chassis to a raised floor vary from site to site, depending on such details as whether your floor needs additional support, where (depending on the location of the floor tiles) the bolt holes need to be, and so on. Work with your vendor to determine your needs for your particular site.
Prerequisites
Before performing this task, you must use the drill template to prepare the floor, unpack the chassis, and move the chassis into position. See the "Unpacking the Chassis" section, the "Moving the Chassis" section, and the FCC sections of Cisco CRS-1 Carrier Routing System Multishelf System Description.
Required Tools and Equipment
You need the following parts to perform this task:
•Drill hole template (Cisco product number CRS-LCC/FCC-DRL=)
•Floor anchor bolt kit (contact a vendor such as Hilti for assistance in identifying a bolt kit solution)
Note The full list of tools depends on the anchor bolt kit you use. See the documentation for the anchor bolt kit for details.
Steps
To secure the chassis, follow these steps:
Step 1 Using the drill template, drill pilot holes into the floor at the indicated locations.
Step 2 Remove the drill template, and drill the indicated anchor bolt holes into the floor at the pilot hole locations. If for some reason, primary hole locations can not be drilled out, alternative mounting holes can be drilled and used with the inrigger kit. See the "Installing the Inrigger Kit" section.
Step 3 Insert bolts and nuts into the floor as appropriate. (A Hilti kit provides instructions on how to install the anchors in the floor.)
Step 4 Carefully move the chassis into place over the bolt holes. See the "Moving the Chassis" section for details on moving the chassis with the dolly.
Note Where side clearance is not enough to use the dolly, you must first lower the chassis to the floor using steps 5 and 6 that follow, then slide it into place.
Step 5 Lock the dolly caster antirotation and brake systems.
Step 6 With a person on each side of the chassis, turn all four cranks of the dolly counterclockwise slowly to lower the chassis to the floor.
Note The dolly has four separate cranks, each of which works independently. It is best for you to turn each crank as simultaneously as possible when lifting the chassis so as to not put undue stress on the chassis frame or dolly and reduce the risk of tipping.
Caution The FCC weighs 780 lb (323 kg) when shipped (with fan trays and impedance carriers installed), is 80.0 in. (203 cm), and should be handled carefully to eliminate the risk of tipping the chassis over.
Step 7 Remove the dolly from the chassis.
Step 8 Insert all anchor bolts.
Step 9 Tighten all bolts and nuts.
What to Do Next
After performing this task, you may install the optional inrigger kit. See the "Installing the Inrigger Kit".
If you choose not to install the optional inrigger kit, unpack and install all remaining chassis parts. See the "Unpacking the Other Pallets" section for unpacking information and Installing the Cisco CRS-1 Carrier Routing System Fabric Card Chassis to locate the installation instructions for the individual parts.
Installing the Inrigger Kit
This section describes how to attach the inrigger kit (see Figure 10) to the FCC. The kit allows you to mount the chassis to the floor by providing offset holes for mounting. Primary and secondary bolt locations exist for securing the chassis to the floor. The drill template that is shipped with the chassis has two locations available for bolting the chassis the floor; the inrigger kit is needed if your site is such that you cannot bolt the chassis down at the primary or secondary location. See Cisco CRS-1 Carrier Routing System Multishelf System Site Planning Guide for further details.
Note The front (SFC) and rear (OIM) side inrigger blocks are both installed from the front (SFC) side of chassis.
Figure 10 Inrigger Blocks
Prerequisites
Before performing this task, you must prepare the floor, unpack the chassis, move the chassis into position, and remove the lower fan tray. See the "Unpacking the Chassis" section, the "Moving the Chassis" section, "Removing a Fan Tray" in Chapter 4 of Installing the Cisco CRS-1 Carrier Routing System Fabric Card Chassis, and the FCC sections of Cisco CRS-1 Carrier Routing System Multishelf System Description.

Step 3 Insert the two inrigger bolt blocks (one for each side) into the front (SFC) side of the chassis (see Figure 11).
Figure 11 Inserting the Front (SFC) Side Inrigger Chassis Bolt Blocks
Step 4 Insert the two 12-mm Allen bolts (one for each bolt block) into the holes on the top of the inrigger bolt blocks, and use the 12-mm Allen wrench to fully tighten the bolts to secure the bolt blocks to the chassis and the chassis to the floor.
Note The standard floor anchor bolt kit can also be used to secure the chassis to the floor.
Step 5 Install the rear (OIM) side inrigger blocks (one for each side) as outlined in steps 6 and 7.
Note The rear (OIM) side inrigger blocks are installed in the rear of the interior of the chassis. You must access the inrigger mount block attachment location through the front (SFC) side of the chassis.
Step 6 Insert the two inrigger bolt blocks (one for each side) into the rear (OIM) side of the interior of the chassis (see Figure 12).
Figure 12 Inserting the Rear (OIM) Side Inrigger Interior Chassis Bolt Blocks
Step 7 Insert the two 12-mm Allen bolts (one for each bolt block) into the holes on the top of the inrigger bolt blocks, and use the 12-mm Allen wrench to fully tighten the bolts to secure the bolt blocks to the chassis and the chassis to the floor.
What to Do Next
After installing the inrigger kit and securing the chassis to the floor, you need to unpack and install all remaining chassis parts. See the "Unpacking the Other Pallets" section for unpacking information and Installing the Cisco CRS-1 Carrier Routing System Fabric Card Chassis to locate the installation instructions for the individual parts.
