Cisco CRS Carrier Routing System Fabric Card Chassis Unpacking, Moving, and Securing Guide

July 2014

Document Part Number: 78-17535-13

This guide provides instructions for unpacking the Cisco CRS Fabric Card Chassis (FCC) and its components, moving the chassis to its permanent location, and mounting and securing the chassis. The companion document to this guide is Cisco CRS Carrier Routing System Multishelf System Site Planning Guide , which describes how to plan and prepare your site facilities for the installation of a switch fabric card chassis.

The Cisco CRS Fabric Card Chassis is part of the Cisco CRS carrier routing system multishelf system, The CRS multishelf system consists of LCC and FCC combinations:

  • Fabric Card Chassis (commonly referred to as FCC)—the mechanical enclosure that contains the second stage (S2) of the switch fabric in multishelf systems, system controllers, fiber modules to interconnect to the LCC, and its own power and cooling systems.
  • 16-Slot Line Card Chassis (commonly referred to as LCC)—the mechanical enclosure that contains the line cards, line card interfaces on the PLIMs, route processors (RPs) or forwarding processors (FPs), distributed route processors (DRPs), stages one and three of the three-stage switch fabric (S13), and its own power and cooling subsystems.

The FCC supports either 40 GB switch fabric cards (CRS-FCC-SFC), 140 GB switch fabric cards (CRS-FCC-SFC-140), or 400 GB switch fabric cards (CRS-FCC-SFC-400). An FCC with a mix of 40 GB,140 GB and 400 GB SFCs is not a supported mode of operation. Such a mode is temporarily allowed only during the upgrade process.


Note Throughout this document, the generic term Cisco CRS Carrier Routing system refers to the Cisco CRS-1, Cisco CRS-3, and Cisco CRS-X Carrier Routing Systems, unless otherwise specified.

Preparing To Unpack the Fabric Card Chassis

This section provides information about the Cisco CRS fabric card chassis before you unpack it and transport it to the final installation location. This section contains the following topics:

Chassis Packaging Overview

Depending on the number of options you ordered, the line card chassis (LCCs) and fabric card chassis (FCCs) that make up the multishelf system are packaged and shipped in several shipping crates and pallets that reduce the potential for product damage during routine material handling and shipment. To protect the chassis:

  • Always store the chassis in its original packaging in an upright position.
  • If you plan to store chassis components before the installation, be sure to store the components carefully and in their original shipping containers to prevent accidental damage.

Each shipping box has a label on the outside of the box identifying that box's number among the number of boxes in your shipment. For example 1 of 6, 4 of 6. The fabric card 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. Other system components are shipped in separate crates and can arrive at the final chassis site at different times.


Caution Do not stack the Cisco CRS shipping crates, because serious damage to the system components can occur.

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 depends on the details of the options you ordered, with each package containing a label that describes the contents.

Figure 1 Section of Chassis Inventory List on Outside of Shipping Box

 


Note Crate numbering for chassis packaging is for reference only. This list is only a sample of what a CRS fabric card 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 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.
  • FCC 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. The chassis is shipped with the fan trays and air filter already installed. The switch fabric card slots are populated with blanks and impedance carriers or covered by slot covers.
  • Power components pallet (crate 3) : contains the power components, including the power shelves, PMs (Modular Power) or PEMs (Fixed Power), alarm module, and power bezel and retainer frame.
  • Card pallet (crate 4) : contains the switch fabric cards and shelf controller Gigabit Ethernet (SCGE) cards.
  • Exterior cosmetic components pallet (crate 5)—contains the default exterior cosmetic components for the chassis.

For complete details on the contents of each pallet, see the shipping and parts identification label on the pallet or shipping manifest.

Key Chassis Specifications

Table 2 lists key specifications for the fabric card chassis (FCC). See the Cisco CRS Carrier Routing System Multishelf System Description Guide for a complete list of FCC specifications.

CRS FCC spare chassis weight: 1044 lb (473.6 kg) (Est.)

Dolly Specifications

The dolly that is available for the Cisco CRS LCC and FCC is flexible enough to meet several difficult challenges encountered when first positioning a chassis of this size and weight.


Note The Cisco dolly works with both the CRS 16-Slot Line Card Chassis (LCC) and the Fabric Card Chassis (FCC); the only difference is the lift brackets that are used (see Figure 10 and Figure 11). If you decide to order the dolly (CRS-16-LIFT/B) and you have a Cisco CRS FCC, then you must order the FCC lift brackets (CRS-FCC-LIFT-BRKT).


Some challenges moving a chassis on the dolly include limited hallway or doorway width, doorway thresholds, ramps, and tight corners along the transport route. To overcome these challenges, use the dolly in either of these configurations:

  • 90-degree configuration— The dolly assemblies are shipped in this configuration. In some cases this configuration is needed to transport the chassis. Use the 90-degree configuration to move the chassis off of the pallet. Extra care should be used with this configuration to ensure that the chassis does not tip during transport.
  • 180-degree configuration— This configuration is a more stable configuration for transporting the chassis. The 180-degree position is the recommended configuration for moving the chassis.

Both configurations are acceptable to transport the as-shipped chassis.

Table 3 lists the specifications for the dolly.

Note In the event that the dolly supplied by Cisco is not the appropriate method of transportation, consult Cisco Technical Staff to determine a method of transportation appropriate for the site. Ensure that the alternate moving device is capable of moving the chassis safely, supporting the weight of the chassis, and is capable of preventing the chassis from tipping.


Safety Guidelines


Caution Before you perform any procedure outlined in this document, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment.

These guidelines are for your safety and to protect equipment. Guidelines do not include all hazards. Be alert.


Note Review the safety warnings listed in Regulatory Compliance and Safety Information for the Cisco CRS 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 optical interface modules (OIMs), 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.

Verifying the Securing Location

Verifying the recommended space ensures that you have enough space available to perform the initial installation of the chassis and its components.

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 Carrier Routing System 16-Slot Line Card Chassis Site Planning Guide and Cisco CRS Carrier Routing System Multishelf System Site Planning Guide .

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 the use of an ESD-preventive strap whenever you handle network equipment or one of its components.

These 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 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 from only ESD voltage on the body: ESD voltage on clothing can still cause damage.

Caution When unpacking and setting parts aside, it is important to set them either in their original antistatic packaging or on an antistatic mat to avoid static discharge.

Unpacking the Cisco Dolly

The dolly is a Cisco-supplied orderable item. The shipping crate contains the dolly units, positioned in the 90 degree configuration as shown in Figure 5. This section describes how to unpack and position the dollies.


Note The dolly will work with both the CRS 16-Slot Line Card Chassis (LCC) and the Fabric Card Chassis (FCC); the only difference is the lift brackets that are used (see Figure 10 and Figure 11).



Note In the event that the dolly supplied by Cisco is not the appropriate method of transportation, consult Cisco Technical Staff to determine a method of transportation appropriate for the site. Ensure that the alternate moving device is capable of moving the chassis safely, supporting the weight of the chassis, and is capable of preventing the chassis from tipping.


Prerequisites

No prerequisites exist for this task.

Required Tools and Equipment

You need the following tools (only used to remove packaging) to perform this task:

  • 3/8-in. ratchet wrench
  • 9/16-in. socket and a 5/8-in. socket
  • Phillips #2 screwdriver (used to remove the clip from the dolly crate)

Caution The dolly should be used only for transporting the as-shipped chassis.

Steps

To unpack the dolly, follow these steps:


Step 1 Carefully move the pallet containing the dolly to the location where you plan to unpack it. The dolly arrives as two separate, identical units, one unit each for the front and back of the chassis.

Step 2 Remove the clip tool from the dolly shipping crate as shown in Figure 2.

Each dolly stopper has two holding bolts. Note that Figure 4 shows only one dolly unit. Remove the other unit using the same steps.

Step 7 Release the caster brakes and remove the dolly from the pallet.

Step 8 Remove the LCC lift brackets from the dolly. Use the 3/8-in. ratchet wrench with 12-mm hex bit (provided by Cisco) to remove the two LCC dolly-to-chassis lift brackets and set the LCC lift brackets carefully aside. Repeat this step for the second dolly unit.


Note If the dolly is being sent from a previous installation, verify the bracket type (LCC, FCC) before removing. Brackets need to be removed prior to attaching to the chassis.



Caution Each dolly unit weighs approximately 126 lb (57 kg). We recommend that at least two people remove the unit from the pallet.

Figure 5 shows the dolly 90-degree configuration with callouts pointing to components and LCC lift brackets (see Figure 22 for the dolly with FCC lift brackets) still attached. To use the dolly for a Cisco fabric card chassis, you must order the FCC lift brackets.

What to Do Next

After unpacking the dolly, unpack the chassis.

Unpacking the CRS Fabric Card Chassis

This section describes:

Required Tools and Equipment

You need:

  • 3/8-in. ratchet wrench
  • 10-mm hex bit (provided by Cisco included in the dolly packaging)
  • 11/16-in. socket (to remove the top wood and frame cushion system)
  • Ladder or step platform

Prepare the Fabric Card Chassis For Unpacking

The chassis is shipped on a pallet by itself in a plywood box. The chassis is unpacked before all other shipping boxes, except for the dolly lifting device.

Prerequisites

Before unpacking the chassis, be sure to have sufficient room around the chassis pallet for unpacking.

Steps

To prepare the chassis for unpacking, follow these steps:


Step 1 Locate a large area to accommodate the chassis and move crate with pallet jack to that location.


Caution The crated Cisco CRS fabric card chassis is heavy and tall and it must be handled carefully to eliminate the risk of tipping the chassis over. We recommend using that at least two people to handle and move the chassis.

Step 2 Go to the next section, Unpacking the Chassis.


Note The crated CRS fabric card chassis is moved first. All other component shipping boxes can remain in the receiving area or as space allows by your site, until the chassis is secured in its final location.



 

Unpacking the Chassis

Steps

To unpack the chassis, follow these steps:


Step 1 Remove the hinge mechanisms from front door only. Raise and twist the lock hinges on the sides and the base of the plywood box (Figure 7).

Step 2 Remove the front cover and set it carefully aside.


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.


Step 3 Disengage the remaining latches from the shipping box. There are two on each side of the shipping box.

Step 4 Using at least two people, lift and remove the three-sided box and place aside. The chassis is exposed on the pallet protected by a shipping bag secured with tape around the bag.

Step 5 Figure 8 shows the wooden box removed from the chassis and the protective bag still attached to the chassis with tape.

Step 6 You need a ladder to remove the four top cover bolts as shown in Figure 9. Use the 3/8-in. ratchet wrench with 11/16-in. socket to loosen the four bolts holding the top wood and frame cushion system from the top of the shipping box. Once the four bolts are loosened, remove each bolt manually and place aside, then remove the top wood and frame cushion system from the chassis.

Figure 9 Location of the Four Bolts On the FCC Shipping Box Top Cover

 


Note Do not remove the chassis bag until you are ready to move and install the chassis.


Step 7 When you are ready to remove the chassis bag, unseal the tape that exists around the perimeter of the chassis (as shown in Figure 8) base and pull the bag off the chassis.


 

What to Do Next

After performing this task, go to the next section Attaching the Dolly to the Chassis and Removing the Chassis Pallet.

Attaching the Dolly to the Chassis and Removing the Chassis Pallet

This section describes how to remove the LCC lift brackets from the dolly and use the FCC lift brackets, attach the dolly to the Cisco CRS FCC, and to remove the chassis shipping pallet. Only the 90-degree dolly configuration is used to remove the chassis from the pallet.


Note The dolly ships with the line card chassis (LCC) lift brackets installed, therefore you must order the FCC lift brackets (bolts are the same) for a Cisco fabric card chassis. See Figure 10 and Figure 11 for the differences in the lift brackets.


Figure 10 shows the LCC lift brackets and Figure 11 shows the FCC lift brackets and the bolts that both lift bracket types use.

Figure 12 Attaching the Cisco Dolly To the Chassis—Instructions

 

Prerequisites

Before attaching the dolly to the chassis, unpack the chassis and unpack the dolly, and remove LCC lift brackets from the dolly.

Required Tools and Equipment

You need these tools and part to perform this task:

  • 2.5mm hex key (to remove the covers)
  • 14-mm socket
  • 3/8-in. ratchet wrench with 6-in. extension
  • 12-mm hex bit (included in the dolly packaging)
  • Dolly (Cisco product number CRS-16-LIFT/B)
  • FCC lift brackets (CRS-FCC-LIFT-BRKT)

Steps

To attach the dolly to the fabric card chassis, follow these steps:


Step 1 Using the Hex socket and wrench remove the four bolts (½-13 x 3.5 in. long hex-head) that connect the pallet to each corner of the chassis base as shown in Figure 13.

Figure 13 Remove Four Bolts That Attach the Chassis to the Pallet

 


Note The lift brackets must be attached to the chassis first.


Step 2 Select a FCC lift bracket (the LCC lift brackets have already been removed), as shown in Figure 11. There are two identical lift brackets for the right front and left rear and two identical lift brackets for the right rear and left front.

Step 3 Fit the FCC brackets on all four sides of the chassis.


Note The LCC lift brackets install from the sides of the chassis and uses 50-mm bolts, while the FCC lift brackets install from the front and rear of the chassis and uses 40-mm bolts.


Step 4 Bolt the FCC lift brackets to the chassis. Insert the 40-mm socket-head cap screw that connects the left lift bracket to the bolt block on the lower front corner of the front side of the chassis, and use the 14-mm hex drive socket to tighten it. Repeat this step for the right lift bracket to attach the bracket to the chassis. See Figure 14.

Figure 14 Attaching the FCC Lift Bracket Bolts to the Chassis (Oblique View)

 

Step 5 Repeat Step 3 and Step 4 for the rear side of the chassis.

Step 6 If the dolly caster brakes are locked, then release them and slide the dolly towards the lift brackets on the chassis as shown in Figure 15 so that the pins on the upper side of the unit align with the holes on the lift brackets on the PLIM side of the chassis. The dolly and lift brackets must align with each other to easily insert the bolts and secure the dolly to the lift brackets.

Figure 15 Sliding the Dolly to the FCC Lift Brackets On the Chassis

 

Step 7 Bolt the lift brackets to the dolly. Insert the 30-mm socket-head cap screws (shorter screw, as shown in Figure 10) and use the 14-mm hex drive socket to tighten it. Repeat this step for the right lift bracket to insert the two bolts that bolt the lift bracket to the dolly.

Step 8 Repeat Step 6 and Step 7 for the rear (MSC) side of the chassis.

Step 9 After all bolts are secured, remove the chassis pallet following these steps:

a. Using two people (one person working on each dolly unit), turn the two lifting cranks to lift the chassis about 3/4 of an in. above the pallet, as shown in Figure 16.

Figure 16 Example of Adjusting the Height of the Dolly

 

b. Slide the pallet from under the chassis as shown in Figure 17.

Figure 17 Slide Pallet From Under Chassis

 

c. Using two people (one person working on each dolly unit), lower the chassis (see Figure 18) to within 1 in. of the floor. See the height label on the dolly lift wheel assembly.

Figure 18 Lowering the Chassis

 

d. Depending on the transport route and the moving space requirements at your site, the dolly can be used to move the chassis in the 90-degree or 180-degree configuration. The 180-degree position is the recommended configuration for moving the chassis.


Warning To reduce the risk of dolly instability, chassis damage, or personal injury, do not raise the equipment more than 1 in. (2.54 cm) above the floor during transportation. Statement 358



 

What to Do Next

After removing the shipping pallet from the chassis, move the chassis. First read the Important Notice About Transporting the Chassis.

Important Notice About Transporting the Chassis

Either a fork lift or pallet jack can be used to transport a crated chassis only.

Throughout this document we refer to the dolly (supplied by Cisco) as the required means to transport the uncrated chassis from the shipping dock to the chassis final location.


Note In the event that the dolly supplied by Cisco is not the appropriate method of transportation, consult Cisco Technical Staff to determine a method of transportation appropriate for the site. Ensure that the alternate moving device is capable of moving the chassis safely, supporting the weight of the chassis, and is capable of preventing the chassis from tipping.



Caution When using any type of device to transport the chassis, exercise extreme caution and follow proper safety practices.

Moving the CRS Fabric Card Chassis

This section presents these topics:

Cisco Dolly and Chassis Moving Guidelines

When you use the dolly to 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, as shipped.
  • 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 lifting 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 moving the chassis using a dolly , follow these guidelines:

Make sure that you have at least two people to transport the chassis. Never transport the chassis by yourself.

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.

Dolly is used to transport the chassis. 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.

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 two people to transport the chassis up and down a ramp. One person in the rear pushing, one person at the front pulling, and one steering the chassis.

Dolly is optimized to move the chassis on flat surfaces. It is not designed to move the chassis on ramps greater than 1 inch of rise for every 6 inches of run. If the ramp exceeds this maximum limit, consult with Cisco Technical Staff.

Exercise extreme caution when moving chassis up an incline of any angle.


Caution Use the recommended 180-degree configuration to transport a chassis. If the 90-degree configuration is used, then the chassis is more likely to tip. Use caution and take extra care in rolling the chassis up a ramp. Always follow proper safety practices whenever moving a CRS chassis.


Note The following warning statements are also documented in the Cisco Regulatory Compliance and Safety Information for the Cisco CRS Carrier Routing System.



Warning Cisco does NOT recommend moving a fully populated chassis.



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 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 In order to reduce the risk of chassis damage or personal injury when replacing a fully-loaded, existing FCC chassis, do not move the chassis in a configuration that is greater than the as-shipped chassis. Before attaching the dolly and moving the chassis, remove power modules, switch fabric and fiber 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



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.

Moving the Chassis

Prerequisites

Before performing this task, make sure that the dolly is in the correct configuration, is firmly attached to the chassis, and that the dolly brakes are in the locked position.


Note If a dolly configuration change is required, the go to the section, Modifying the Dolly Configuration to Move the Chassis.


Steps

This section describes how to move the FCC:


Step 1 With a person on each side of the chassis, turn all four lifting cranks of the dolly slowly clockwise. Lift the dolly to the Transport marking on the height label on each lift assembly leg. The dolly must be used to transport the chassis unless an alternate moving method has been approved by Cisco. To reduce the risk of dolly instability, chassis damage, or personal injury, do not raise the equipment more than 1 in. (2.54 cm) above the floor during transportation which is the standard recommendation for flat surfaces and thresholds.


Note The dolly has four separate lifting cranks, each of which works independently. It is best to turn each lifting crank simultaneously when lifting the chassis to keep the chassis as level as possible so as to not put undue stress on the chassis frame or dolly and to reduce the risk of tipping.



Caution The Cisco CRS FCC is heavy and tall, and it must be handled carefully to eliminate the risk of tipping the chassis over. We recommend that at least two people handle and move the chassis.


Note The 180-degree position is the recommended configuration for moving the chassis. If needed because of site requirements, rotate the dolly to the 90-degree position. If you are transporting in a 90-degree configuration, then have at least two people moving the chassis to prevent any transporting hazard. 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 swing component to minimize the risk of tipping. When you have rotated the dolly, raise the chassis again. See the “Modifying the Dolly Configuration to Move the Chassis” section for further information.


Step 2 Unlock the dolly caster antirotation and brake systems.


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, or over bumps more than 1.5 inches high (such as door thresholds).


Step 3 Use at least two people to transport the chassis up any ramp. Position one person in the front of the chassis to pull, one person at the rear of chassis to push, and one person steering the chassis to transport the chassis.

Step 4 Roll the chassis carefully into position. Figure 21 shows a typical floor plan from the top of the chassis. For additional details on making your site ready for the chassis, see Cisco CRS Carrier Routing System Multishelf System Site Planning Guide .

Figure 21 shows a typical site floor plan for a Cisco FCC.

Step 5 Remove the dolly.


 

What to Do Next

After moving the chassis, secure the chassis.


Warning Do not permanently locate the equipment on the dolly. Safely store the dolly after use. Statement 357


Securing the Chassis

This section presents these topics:

Site Preparation

Before moving the chassis into place and securing it, you must make sure that your site is prepared. Because of its size and weight issues, the chassis must be securely bolted to the floor. Several possible bolting configurations exist for the chassis, including using the optional alternate chassis floor-mounting kit. Bolt hole templates are provided for the various securing options.

For complete details on preparing your site for the chassis, see Cisco CRS 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 Carrier Routing System Fabric Card Chassis Site Planning Guide .

Securing the Chassis To the Floor

This section describes how to secure the Cisco CRS FCC to a concrete floor. The chassis is shipped with a drill hole template (CRS-LCC-DRILLTEMP(=)) to assist you in putting the bolts in the proper position on the floor. The template is used for both raised floors and slabs. The drill hole template identifies primary, secondary and alternate mounting locations for securing the chassis to the floor. Whenever possible, use the:

  • Primary mounting locations
  • Second and alternate locations only when the primary locations are not available

If alternate mounting locations are used, an alternate chassis mounting kit (CRS-FCC-ALTMNT) (orderable from Cisco) needs to be installed on the chassis

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 (as local practice applies for raised floors), where (depending on the location of the floor tiles) the bolt holes need to be and so on. Work with your facilities representative to determine your needs for your particular site.

Prerequisites

Identify chassis location before performing this task.

Required Tools and Equipment

You need the following parts to perform this task:

  • 3/8-in. ratchet wrench
  • Set of standard and metric sockets
  • Drill and bits for masonry and wood

Note The full list of tools depends on the anchor bolt kit you use. See the documentation for your anchor bolt kit for details.


Steps


Step 1 Using the drill hole template, drill pilot holes into the floor at the identified locations.


Step 1 Refer to your mounting kit instructions for anchoring hardware to the floor. Remove the drill hole template, and drill the indicated anchor bolt holes into the floor at the pilot hole locations.


Step 1 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 and then slide it into place.


Step 2 Lock the dolly caster antirotation and brake systems.

Step 3 With a person on each side of the chassis, turn all four lifting cranks of the dolly counterclockwise slowly to lower the chassis to the floor.


Note The dolly has four separate lifting cranks, each of which works independently when lifting or lowering the chassis. It is best to turn the lifting cranks simultaneously when lifting the chassis so as to not put undue stress on the chassis frame or dolly and reduce the risk of tipping.


Step 4 Remove the dolly from the chassis.

Step 5 Insert all anchor bolts.

Step 6 Tighten all bolts and nuts.

Step 7 Replace corner brackets on the chassis.


 

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-degree or 90-degree position, depending on the needs of your site. For further information on the two configurations, see the “$paratext>” section. See the “Cisco Dolly and Chassis Moving Guidelines” section section for important recommendations before modifying the dolly configuration.

When changing the configuration of the dolly wheel assemblies (from 180 to 90 degrees or conversely) , follow these guidelines:

  • Lower the chassis to the floor before you change configurations.
  • 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.

Prerequisites

Before performing this task, make certain that the chassis and pallet are on the floor.

Required Tools and Equipment

You need a 3/8-in. ratchet wrench with 12-mm hex bit (provided by Cisco) to perform this task.

Steps

To change the dolly configuration from the 90-degree configuration to the 180-degree transport configuration, follow these steps:


Step 1 Set the caster wheel rotation using the caster antirotation pin. Turn the antirotation pin to a vertical position to lock the caster. See Figure 22.

Step 2 Lock the brakes. Depress the brakes (Figure 22) on each side of the dolly.

Step 3 Using the handles, turn the dolly lifting cranks to raise or lower the dolly according to the label rotation direction (see Figure 18). Turn the lifting cranks until the dolly casters are just off the floor.

Step 4 Unlock the dolly caster brakes and antirotation pins.

Step 5 On the dolly unit attached to the front fabric card side of the chassis, use the wrench to remove the two holding bolts on the left side lift arm swing bracket.

Step 6 Swing the lift arm swing bracket to the side as shown in Figure 23. Reinsert the holding bolts and partially tighten the bolts.

Step 7 On the dolly unit attached to the front side of the fabric card chassis, use the 3/8-in. ratchet wrench with 12-mm hex bit (provided by Cisco) to remove the two holding bolts on the left side lift arm swing bracket to convert to the 180-degree configuration.

Step 11 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 configuration position.



 

Installing the Alternate Chassis Floor-Mounting Kit

This section describes how to attach the alternate chassis floor mount kit (see Figure 25) 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 alternate chassis floor mount kit is needed if your site is such that you cannot bolt the chassis down at the primary or secondary location. See Cisco CRS Carrier Routing System Multishelf System Site Planning Guide for further details.


Note The alternate chassis floor mount kit is an orderable item. If you cannot use the primary or secondary mounting holes, then use the optional alternate chassis floor mount kit for an alternate set of mounting holes. Use this kit only if there is no other means to mount the chassis to the floor.



Note The front fabric cards and rear (OIM) side alternate chassis floor mount kit blocks are both installed from the front fabric card side of chassis.


Figure 25 Alternate Chassis Floor-Mounting Kit Blocks

 

Prerequisites

Before installing the alternate chassis floor mount kit, you must prepare the floor, unpack the chassis, move the chassis into position, and remove the lower fan tray. To remove a fan tray, see the Cisco CRS Carrier Routing System Fabric Card Chassis Installation Guide .

Required Tools and Equipment

You need these tools and part to perform this task:

  • Drill hole template (Cisco product number CRS-LCC-DRILLTEMP(=)
  • 12-mm Hex wrench
  • Alternate chassis floor-mounting kit (Cisco product number CRS-FCC-ALTMNT(=)

Steps

To install an alternate chassis floor-mounting kit, follow these steps:


Step 1 Make sure that the lower fan tray has been removed.

Step 2 Install the front fabric card side alternate chassis floor-mounting kit blocks (one for each side) as outlined in steps 3 and 4.

Step 3 Insert the two alternate chassis floor-mounting bolt blocks (one for each side) into the front fabric card side of the chassis (see Figure 26).

Figure 26 Inserting the Front Switch Fabric Card Side Alternate Chassis For-Mounting Bolt Blocks

 

Step 4 Insert the two 12-mm hex bolts (one for each bolt block) into the holes on the top of the alternate chassis floor-mounting bolt blocks, and use the 12-mm hex 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 alternate chassis floor-mounting blocks (one for each side) as outlined in steps 6 and 7.


Note The rear (OIM) side alternate chassis floor-mounting blocks are installed in the rear of the interior of the chassis. You must access the alternate chassis floor-mounting kit block attachment location through the front switch fabric card side of the chassis.


Step 6 Insert the two alternate chassis floor-mounting bolt blocks (one for each side) into the rear (OIM) side of the interior of the chassis (see Figure 27).

Figure 27 Inserting the Rear (OIM) Side Alternate Chassis Interior Floor Mounting Bolt Blocks

 

Step 7 Insert the two 12-mm hex bolts (one for each bolt block) into the holes on the top of the alternate chassis floor-mounting bolt blocks, and use the 12-mm hex 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 alternate chassis floor-mounting 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 Cisco CRS Carrier Routing System Fabric Card Chassis Installation Guide to locate the installation instructions for the individual parts.

Unpacking the Other Pallets

This section describes how to unpack the primary, secondary, power, and exterior cosmetic component pallets for the FCC.

Prerequisites

No prerequisites exist for this task.

Required Tools and Equipment

You need these tools to perform this task:

  • Antistatic mat
  • Phillips #2 screwdriver
  • A pair of 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 that is 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 pair of 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.

Step 6 Unpack exterior cosmetic components from the packaging, and set the components carefully aside on an ESD-immune surface for installation.


Note If any components 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.



 

Component Return Information

Before preparing to ship back 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 prior to assigning a 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 for the chassis. The serial number label for the FCC is located on the rear (OIM) side of the FCC (see Figure 28).
