This publication describes how to remove and install the Cisco 12016, Cisco 12416, and Cisco 12816 Router chassis.
The following sections are included in this publication:
The Cisco 12016, Cisco 12416, and Cisco 12816 Router chassis is a sheet-metal enclosure that consists of three integral card cages and two blower module bays. (See Figure 1.) Because the router can be configured with either an AC- or DC-input power subsystem, the power shelf for the router is a separate unit that attaches to the top of the chassis.
Figure 1 Cisco 12016, Cisco 12416, and Cisco 12816 Router (Front View, AC-Input Power Subsystem Shown)
Chassis Card Cages
The router has three integral card cages: the upper card cage, the lower card cage, and the switch fabric card cage. (See Figure 1.)
The upper card cage has eight user-configurable slots that support a combination of line cards and a route processor (RP). The far left slot in the upper card cage is a dedicated slot for a pre-installed alarm card. The far right slot (slot 7) in the upper card cage is reserved for the RP. The remainder of the slots in the upper card cage (slots 0 through 6) can be populated with any of the line cards supported by the router.
The lower card cage also has eight user-configurable slots that support more line cards and an optional, redundant RP. The lower card cage is an inverted, or head-down, copy of the upper card cage, meaning that cards are installed the same way they are installed in the upper card cage, but in an inverted or head-down orientation. The far right slot in the lower card cage is dedicated to a second alarm card, followed by slots 8 through 15 moving right to left.
Note If the router is equipped with an optional, redundant RP, it must be installed in the far left slot of the lower card cage (slot 8). If the router is not equipped with an optional, redundant RP, a line card can be installed in slot 8 of the lower card cage.
The switch fabric card cage has five slots for the cards that contain the switch fabric circuitry. These cards are the clock and scheduler cards (CSCs) and the switch fabric cards (SFCs). The card slots in the switch fabric card cage are keyed to accept specific card types. The two far left slots (labeled CSC0 and CSC1) accept CSCs; the three far right slots (labeled SFC1, SFC2, and SFC3) accept SFCs.
Caution All line card slots must be filled at all times to maintain proper chassis card cage alignment; blank filler line cards are available for this purpose as necessary. Installed line cards remain in their slots except during replacement.
The three card cages are tied together electrically through a passive system backplane in the back of the chassis. Nearly all the wiring in the router is contained within or connected to the chassis backplane. The chassis backplane distributes DC power to all the cards and blower modules in the router and provides the physical communication pathway between cards, both for network data and system communication across the internal system maintenance bus (MBus).
The two removable blower modules at the top and bottom of the chassis (see Figure 1) provide cooling air for all cards in the three card cages. In the power shelf, each power module contains a fan that draws cooler air into the front of the power module and forces warmed air out the back of the power shelf.
The router can be ordered with the AC-input power subsystem with three AC-input power supplies, or the DC-input power subsystem with four DC-input power entry modules (PEMs).
Caution The router must be operated with all its power modules installed at all times for compliance with electromagnetic compatibility (EMC) regulations.
The AC-input power subsystem consists of the AC-input power shelf with bays for three AC-input power supplies. A router ordered with the AC-input power subsystem ships with three AC-input power supplies (full redundant power) installed in the AC-input power shelf. In the full redundant power configuration, the three power supplies participate in an N+1 redundant current-sharing scheme in which current sharing is divided among all three power supplies. If one power supply fails, the system can continue to operate temporarily on the two remaining power supplies. An optional two-level power shelf is also available.
The DC-input power subsystem consists of the DC-input power shelf with bays for four DC-input PEMs. A router ordered with the DC-input power subsystem ships with four DC-input PEMs (full redundant power) installed in the DC-input power shelf. In the full redundant power configuration, modules A1 and B1 provide redundant power for system load zone 1 (the upper blower module and the upper card cage); Modules A2 and B2 provide redundant power for system load zone 2 (the switch fabric card cage, the lower card cage, and the lower blower module).
Preparing for Installation
Installation preparation is presented in the following sections:
Before you perform any procedure in this publication, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment. In addition, review the safety warnings listed in the Regulatory Compliance and Safety Information for the Cisco 12000 Series Internet Router publication that accompanied your router before installing, configuring, or maintaining the router.
The following guidelines are for your safety and to protect equipment. The guidelines do not include all hazards. Be alert.
Safety with Equipment
•Always disconnect all power cords and interface cables before moving the system.
•Never assume that power is disconnected from a circuit; always check.
•Keep tools and assembly components away from walk areas.
•Do not work alone if potentially hazardous conditions exist.
•Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
•Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.
Safety with Electricity
•Before beginning any procedures requiring access to the interior of the router, locate the emergency power-off switch for the room in which you are working.
•Disconnect all power and external cables before installing or removing a router.
•Never assume that power has been disconnected from a circuit; always check.
•Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
•Never install equipment that appears damaged.
•Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.
•If an electrical accident does occur, proceed as follows:
–Use caution; do not become a victim yourself. Disconnect power to the router.
–If possible, send another person to get medical aid; otherwise, assess the condition of the victim and then call for help.
–Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.
In addition, observe the following guidelines when working with any equipment that is disconnected from a power source but still connected to telephone or network wiring:
•Never install telephone wiring during a lightning storm.
•Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
•Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.
•Use caution when installing or modifying telephone lines.
Preventing Electrostatic Discharge Damage
Many router components can be damaged by static electricity. Some components can be damaged by voltages as low as 30V, while static voltages as high as 35,000V can be generated just by handling plastic or foam packing material, or by sliding assemblies across plastic and carpets. Not exercising the proper electrostatic discharge (ESD) precautions can result in intermittent or complete component failures. To minimize the potential for ESD damage, observe the following guidelines:
•Always use an ESD-preventive antistatic wrist strap or ankle strap and ensure that it makes good skin contact.
Caution You should periodically check the resistance value of the ESD-preventive strap. The measurement should be between 1 and 10 megohms.
•When removing or installing a component, make sure the equipment end of your antistatic strap leash is connected to one of the ESD connection sockets on the front of the chassis or to a bare metal surface on the chassis. (See Figure 2.) Avoid contact between the component and your clothing. The ESD-preventive wrist strap only protects the component from ESD voltages on the body; ESD voltages on your clothing can still cause component damage.
•Always place a card component-side-up on an antistatic surface, in an antistatic card rack, or in a static shielding bag. If you are returning the item to the factory, immediately place it in a static shielding bag.
•When installing a line card or RP, use the ejector levers to seat the card connectors in the backplane, then tighten both captive screws on the faceplate of the card. These screws prevent accidental removal, provide proper grounding for the router, and help to ensure that the card connector is seated in the backplane.
•When removing line cards, CSCs, SFCs, or an RP, use the ejector levers to unseat the card connector from the backplane. Pull the metal card carrier out slowly, placing one hand along the bottom of the carrier to guide it straight out of the slot.
•Handle line cards, CSCs, SFCs, or an RP by the metal card carrier edges only; avoid touching the board or any connector pins.
Figure 2 Connecting an ESD-Preventive Wrist Strap to the Router
Required Tools and Equipment
The following tools and equipment are required to remove and install the chassis:
•ESD-preventive wrist strap
•1/4-inch (6.5-mm) and 3/16-inch (4.5-mm) flat-blade screwdrivers
•Number 1 and number 2 Phillips screwdrivers
•3/8-inch (10-mm) nutdriver (for systems equipped with the DC-input power shelf)
•9/16-inch (14-mm) wrench (for chassis hold-down bolts and pallet hold-down bracket bolts)
•3/4-inch (19-mm) socket and ratchet wrench
•A spare router scissor-jack platform (for use in removing the defective chassis from the equipment rack)
•Safety hand truck with retractable safety leg wheels and security strap, such as the Stevens Appliance Truck Company "Escort," Model STEV SRT-M-66 (distributed by McMaster-Carr as Model 2654T6), or an equivalent safety hand truck.
The following publications contain additional information:

•Regulatory Compliance and Safety Information for the Cisco 12000 Series Internet Router
Removing and Installing the Chassis
The router chassis is an integrated, sheet-metal assembly that includes the upper blower module bay, the upper card cage, the switch fabric card cage and air filter door, the lower card cage, and the lower blower module bay. (see Figure 1.) The chassis is mounted in an equipment rack by ten screws (five on each side) that fasten the chassis rack-mounting flanges to the mounting flanges on the rack.
Because you are removing all the components (except the air filter) from the defective chassis and then reinstalling them in the replacement chassis, the procedures that follow are based on these assumptions:
•The replacement chassis, mounted on its scissor-jack platform, is temporarily placed within reach of the rack in which the defective chassis is installed, and is temporarily connected to the same grounding system as the defective chassis.
•A spare scissor-jack platform is available to remove the defective chassis from the equipment rack.
•Components are transferred from the defective chassis to the replacement chassis.
•The replacement chassis, with all the components now installed in it, is inserted into the equipment rack in place of the defective chassis.
This approach has the advantage of protecting system components against damage by eliminating the need to store them even temporarily outside their card cages. It also helps ensure that the physical configuration of the router is maintained, because each transferred component is installed in the same location in the replacement chassis that it occupied in the defective chassis.
Procedures for removing and installing the chassis are described in the following sections:
Unpacking the Replacement Chassis
The process of unpacking the replacement chassis consists of opening and disassembling the shipping package to expose the chassis on the shipping pallet, then removing the chassis and scissor-jack platform from the shipping pallet. See the "Unpacking the Replacement Chassis" section for detailed procedures.
Preparing the Chassis
When the replacement chassis and scissor-jack platform have been placed near the rack site, temporarily connect the central office grounding system or interior equipment grounding system to the supplemental bonding and grounding receptacles on the router. There are two receptacles on the front flanges of the chassis, near the lower corners of the switch fabric card cage. (See Figure 3.) There are also two receptacles on the top of the power interface panel on the back of the chassis. (See Figure 4.) Each bonding and grounding receptacle consists of a round bolt hole and an elongated bolt hole, surrounded by an area of bare metal.
For more information on the bonding and grounding cable and connector requirements, refer to the "Supplemental Unit Bonding and Grounding Guidelines" section in the Cisco 12016, Cisco 12416, and Cisco 12816 Router Installation and Configuration Guide.
Figure 3 Router Front Bonding and Grounding Receptacles
Figure 4 Router Top Bonding and Grounding Receptacles
To complete the preparation of the chassis, follow these steps:
Step 1 Power down the router.
a. Turn off all circuit breakers for the source power lines connected to the power shelf.
b. Verify that the LED labeled PWR OK on each of the power supplies is off, and that the power fan in each power supply is off.
c. Verify that the green LED labeled OK on each blower module is off.
Caution You must power down the router to remove and the install the chassis.
Step 2 Disconnect power from the power shelf. Refer to the Cisco 12016, Cisco 12416, and Cisco 12816 Router Installation and Configuration Guide for detailed procedures.
Step 3 Remove the front covers. Refer to the Cisco 12016, Cisco 12416, and Cisco 12816 Router Installation and Configuration Guide for detailed procedures.
Step 4 Disconnect the RP cables. You must disconnect any cables that are connected to the RP console port, auxiliary port, or either of the Ethernet ports, RJ-45 or MII. Identify each of the RP cable connections and write them down on a piece of paper before you disconnect the cables. After disconnecting the cables, remove them from the chassis and place them safely aside.
Step 5 Disconnect the alarm card cables. You must disconnect any cable that is connected to the external alarm port on either or both of the alarm cards. Identify the alarm cable connections and write them down on a piece of paper before you disconnect the cables. After disconnecting the cables, remove them from the chassis and place them safely aside.
Step 6 Disconnect the line card interface cables. Refer to the installation and configuration note for your specific line card for detailed procedures.
Step 7 Remove the vertical cable-management troughs. One vertical cable-management trough is attached to each side of the chassis by six Phillips screws. (See Figure 5.) Both vertical cable-management troughs must be removed from the chassis before the chassis can be removed from the equipment rack.
a. Insert a Phillips screwdriver through the access holes in the outer surface of the trough and remove the six Phillips screws that secure the trough to the chassis.
b. Set the trough and the screws safely aside. You will need to reinstall the trough on the replacement chassis after it has been installed in the equipment rack.
Figure 5 Removing the Vertical Cable-Management Troughs
Removing and Installing System Components
To remove and install system components from one chassis to another, follow these steps:
Step 1 Remove the blower modules and then install them into the replacement chassis. Refer to the
Cisco 12016, Cisco 12416, and Cisco 12816 Router Installation and Configuration Guide for detailed procedures.
Step 2 Remove the power supplies and the power shelf and then install them into the replacement chassis. Refer to the Cisco 12016, Cisco 12416, and Cisco 12816 Router Installation and Configuration Guide for detailed procedures.
Step 3 Remove the cards from all three card cages and then install them into the replacement chassis.
•For the RP, refer to the RP installation and configuration note for detailed procedures.
•For line cards, refer to the line card installation and configuration note for detailed procedures.
•For CSCs, SFCs, and the alarm card, refer to the Cisco 12016, Cisco 12416, and Cisco 12816 Router Installation and Configuration Guide for detailed procedures.
Removing the Chassis from the Equipment Rack
This section provides the following procedures:
Detaching the Supplemental Bonding and Grounding Connection
If your router has supplemental bonding and grounding cables attached to any of the earth ground cable receptacles on the chassis, you must detach these cable lugs from the chassis before you can remove the chassis from the equipment rack. Two receptacles are located on the front flanges of the chassis, near the lower corners of the switch fabric card cage (see Figure 3) and two receptacles are located on top of the power interface panel on the back of the chassis (see Figure 4).
Step 1 Remove the two bolts, washers, and nuts that secure the bonding and grounding cable lug to the chassis. Save the mounting hardware, because you will use it in a later procedure.
Step 2 Remove the bonding and grounding cable and set it aside.
Removing the Chassis from the Equipment Rack
To remove the chassis from the equipment rack, follow these steps:
Step 1 Position the scissor-jack platform from the original router shipping package in front of the rack-mounting platform in the rack.
Step 2 Use the 3/4-inch (19-mm) socket and ratchet wrench to turn the scissor-jack screw counterclockwise to expand the scissor-jack platform and slowly raise the top of the scissor-jack platform to the same height as the top of the rack-mounting platform. (See Figure 6.)
Figure 6 Positioning the Scissor-Jack Platform to Extract the Chassis
Step 3 Working from the top of the chassis down, remove the screws that secure the chassis to the mounting flanges on the rack (five screws on each side of the chassis). Set the screws aside for use in installing the replacement chassis.
Caution The chassis is still supported by the rack-mounting platform installed in the bottom of the rack, but should be held to prevent the possibility of tipping out of the front of the rack.
Step 4 Position one person in front of the chassis to support and guide it while the second person slowly pushes the chassis to slide it off the rack-mounting table, out of the rack, and onto the scissor-jack platform.
Step 5 With one person positioned on the side of the chassis to prevent it from tipping, install the four chassis anchor clips through the slots in the bottom of the chassis, align the holes with the bolt holes in the platform, and insert and tighten the four bolts to prevent the chassis from shifting on the scissor-jack platform. (See Figure 7.)
Figure 7 Securing the Chassis to the Scissor-Jack Platform
Step 6 With one person positioned on the side of the chassis to prevent it from tipping, use the 3/4-inch (19-mm) socket and ratchet wrench to turn the scissor-jack screw clockwise slowly and close the scissor-jack platform to lower the chassis. (See Figure 8.)
Figure 8 Closing the Scissor-Jack Platform to Lower the Chassis
Step 7 Position the safety hand truck at one side of the chassis, slide the chassis and scissor-jack platform onto the safety hand truck, and secure the chassis to the hand truck with the locking safety strap.
Step 8 Tilt the safety hand truck onto its outrigger wheels to move the chassis to a level, open space with a solid floor, where the chassis can be repackaged for shipping.
If you plan to return the defective chassis to the factory, repackage it in the original shipping container or a replacement shipping container acquired from Cisco. For information on repackaging the chassis, see the "Reinstalling the Chassis and Scissor-Jack Platform in the Shipping Pallet" section and the "Packaging the Replaced Chassis for Shipment" section.
Installing the Replacement Chassis
Procedures for installing the replacement chassis are described in the following sections:
Positioning the Replacement Chassis for Insertion into the Rack
Position the replacement chassis and scissor-jack platform in front of the rack with the back panel of the chassis facing the rack opening, and the back of the scissor-jack platform butted against the rack-mounting platform in the rack. (See Figure 9.)
Figure 9 Positioning the Chassis to Insert It into the Rack
Inserting the Chassis into the Rack
When the chassis and scissor-jack platform have been positioned in front of the rack with the back of the chassis facing the opening between the rack posts, you must expand the scissor-jack platform to raise the chassis to the same height as the rack-mounting platform installed in the rack.
To insert the chassis into the rack, follow these steps:
Step 1 With one person positioned on the side of the chassis to prevent it from tipping, use the 3/4-inch (19-mm) socket, ratchet wrench, and extender bar to turn the scissor-jack screw counterclockwise to expand the scissor-jack platform and slowly raise the chassis to the required installation insertion height. (See Figure 10.)
Figure 10 Raising the Chassis to the Insertion Height
Step 2 Remove the four bolts and anchor clips that secure the base of the chassis to the scissor-jack platform. (See Figure 11.)
Figure 11 Removing the Chassis Retainer Clips
Warning Do not attempt to lift the chassis with the handles on the back and sides of the router. These handles are not designed to support the weight of the chassis, and should be used only to steady and guide the chassis while it is being inserted into or removed from an equipment rack. To reduce the risk of damage to the chassis and serious bodily injury, do not use these handles to lift or support the chassis.
Step 3 Slide the chassis carefully off of the scissor-jack platform and onto the rack-mounting platform in the rack by having one person use the handle on the back of the chassis to pull the chassis into the rack while a second person pushes from the front of the chassis. (See Figure 12.)
Figure 12 Inserting the Chassis into the Rack
Step 4 Push the chassis into the rack until the chassis rack-mounting flanges are flush against the mounting flanges on the rack (or against the optional center-mount brackets, if installed).
Step 5 Close the scissor-jack platform and put it with the rest of the shipping container.
Note Save and reassemble all parts of the shipping container for removing the chassis from the rack and repackaging it should it become necessary to transport the router to another location or return it to Cisco. Do not discard or destroy the shipping container.
Step 6 Look at the bottom group of mounting holes (group A) on the chassis. (See Figure 13.) Identify one of the holes in group A that aligns with a mounting hole on the mounting flanges of the rack.
Figure 13 Chassis Mounting Hole Groups
Step 7 Hold the chassis in position against the mounting flanges on the rack and have a second person insert and loosely tighten one of the mounting screws provided.
Step 8 On the other side of the chassis, adjust the position of the chassis so that the same mounting hole in the bottom group of mounting holes (group A) is aligned with a hole in the mounting flange on the rack, then insert and loosely tighten one of the mounting screws provided.
Step 9 Level the chassis as required, then secure the chassis to the equipment rack by tightening all ten screws (five on each side of the chassis).
Reattaching Supplemental Bonding and Grounding Connections
Figure 14 shows how to attach a supplemental bonding and grounding cable lug to one of the receptacles on either side of the switch fabric card cage on the front of the chassis. Figure 15 shows how to attach a supplemental bonding and grounding cable lug to one of the receptacles on either side of the top of the power interface panel on the back of the chassis.
Figure 14 Router Front Bonding and Grounding Receptacles
Figure 15 Router Top Bonding and Grounding Receptacles
Step 1 Locate the bonding and grounding receptacle on the router that you plan to use.
Step 2 Position the bonding and grounding cable lug over the bonding and grounding receptacle holes on the chassis.
Step 3 Insert the two M6 bolts that you removed earlier through the holes in the cable lug and chassis, then install the locking washers and nuts.
Step 4 Ensure that the bonding and grounding cable does not interfere with other router hardware, then tighten the nuts and bolts to secure the bonding and grounding cable lug to the chassis.
Reattaching the Vertical Cable-Management Troughs
To reattach the vertical cable-management troughs, use Figure 5 as a reference and follow these steps:
Step 1 Align the trough so that the access gate opens toward the front of the chassis.
Step 2 Align the screw holes on the inside panel of the trough with the standoffs in the chassis rack-mounting flange near the upper horizontal cable-management tray.
Step 3 Use your fingers to insert screws into the two holes and screw them in to hold the trough in place.
Step 4 Insert a Phillips screwdriver through the access holes in the outer panel of the trough and loosely tighten the two screws.
Step 5 Insert and start screws in the middle two standoffs and the bottom two standoffs.
Step 6 Check the alignment of the trough on all six holes, then use the Phillips screwdriver to tighten all six screws.
Completing the Installation
To complete the installation, follow these steps:
Step 1 Reconnect power to the power shelf. Refer to the Cisco 12016, Cisco 12416, and Cisco 12816 Router Power System Procedures Guide for detailed procedures.
Step 2 Reconnect the line card interface cables. Refer to the line card installation and configuration note for detailed instructions.
Step 3 Reconnect the cables to the RP. Refer to the RP installation and configuration note for detailed procedures.
Step 4 Reconnect any alarm card cabling. Refer to the Cisco 12016, Cisco 12416, and Cisco 12816 Router Clock and Scheduler, Switch Fabric, and Alarm Card Replacement Instructions for detailed procedures.
Step 5 After performing the steps in the "Checking Router Operation" section, install the chassis front covers. Refer to the Cisco 12016, Cisco 12416, and Cisco 12816 Router Installation and Configuration Guide for detailed instructions.
Checking Router Operation
To restart the router and verify that it restarts successfully after replacing the chassis, follow these steps:
Step 1 Verify that the following conditions are true:
•All cards are fully inserted in their slots, and all captive screws are tightened.
•Line card cable-management brackets are attached to their respective line cards and all captive screws are tightened.
•Interface cables are completely seated in their line card connectors.
•Interface cables are routed neatly through the cable-management system.
•Any empty card slots are filled with card blanks.
•When the faceplate of a card does not completely fill the card slot opening, a narrow card filler panel is installed to ensure proper air flow through the chassis and proper compliance with electromagnetic compatibility (EMC) regulations.
•Power modules are fully inserted in their bays and their ejector levers are all completely closed and secured.
•Power shelf cables are fully connected to both the power shelf and the power source, and are secured with appropriate strain relief.
•On a router equipped with the DC-input power subsystem, the power cable cover is installed over the cable connectors on the back panel of the DC-input power shelf.
•The Flash memory card that shipped with your system is installed in PCMCIA slot 0 of the RP.
Note By default, a Flash memory card containing a valid Cisco IOS software image is inserted in PCMCIA slot 0 before the router is shipped. Also by default, the software configuration register is set to 0x0102, which causes the router to boot automatically from the Cisco IOS software image stored on the Flash memory card.
Step 2 Ensure that a console terminal is connected to the RP console port and turned on, or that you have a remote login to the router from another device through a telnet session. (You will need to check the startup banner and displays to ensure that the system restarts properly and that all the interfaces reinitialize in the proper state.)
Step 3 Switch on all source voltage circuit breakers that control power to your system.
Step 4 Observe the power module LEDs:
•When a AC-input power supply is seated in its power shelf bay and connected to an AC power source supplying power within the required range, the green LED labeled PWR OK on the power supply faceplate should be on and the power supply fan should also be on. This is normal behavior.
•When a DC-input PEM is seated in its power shelf bay, connected to a DC power source supplying power within the required range, and the circuit breaker on the faceplate of the PEM is switched on, the green LED labeled PWR OK on the PEM faceplate should be on and the PEM fan should also be on. This is normal behavior.
Note Because the power module LEDs and the monitoring circuits are redundantly powered by the other power module in the power shelf load zone PEM pair, the LED labeled FAULT on the PEM can be on even when the circuit breaker for that PEM is switched off or there is no DC-input power source for that PEM. On a newly installed PEM, when DC-input source power is available to the PEM and the circuit breaker is switched on, the LED labeled FAULT should go off and the LED labeled PWR OK should go on.
Step 5 Visually check the two LEDs on the front of each blower module. When the blower module is operating correctly, the green LED labeled OK should be on and the red LED labeled FAIL should be off. Listen for the blowers in the blower modules; you should immediately hear them operating. In a noisy environment, the blowers might be difficult to hear; therefore, place your hand in front of the exhaust vents near the top and bottom rear of the chassis to verify that the blowers are operating.
Step 6 Visually check the LEDs on the two alarm cards. When the system is operating correctly, the following LED conditions should be true:
•All three system alarm LEDs should be off.
•The alarm card status LED labeled ENABLED should be on; the LED labeled FAIL should be off.
•The LED labeled ENABLED for each CSC and SFC in the switch fabric card cage should be on; the LED labeled FAIL should be off.
Step 7 On the console terminal, verify that the console displays the system banner and that the system and all interfaces initialize successfully.
If the power supplies do not power up, or if the system or any interfaces do not initialize properly, refer to the Cisco 12016, Cisco 12416, and Cisco 12816 Router Installation and Configuration Guide that shipped with your router for additional information and installation troubleshooting procedures. If you are still unable to resolve the problem, contact your Cisco service representative for assistance.
Packaging the Replaced Chassis for Shipment
This section provides the following procedures:
Reinstalling the Chassis and Scissor-Jack Platform in the Shipping Pallet
To install the chassis and scissor-jack platform on the shipping pallet, use Figure 16 as a reference and follow these steps:
Step 1 Use the bolts you removed earlier to attach the eight hold-down brackets to the four sides of the scissor-jack platform (two brackets on each side).
Note The hold-down brackets are not symmetrical: The bracket plate that fastens to the side of the scissor-jack platform is narrower than the bracket plate that fastens to the top of the pallet, and has smaller-diameter bolt holes.
Step 2 Position the U-shaped pallet body behind the scissor-jack pallet with the opening facing the back panel of the chassis.
Step 3 Use the 3/4-inch (19-mm) socket and ratchet wrench to turn the scissor-jack screw slowly counterclockwise to expand the scissor-jack platform and raise the top of the scissor-jack platform high enough for the hold-down brackets to clear the top of the pallet body.
Step 4 Slide the pallet body around the scissor-jack platform.
Figure 16 Installing the Chassis and Scissor-Jack Platform on the Shipping Pallet
Step 5 Slide the pallet front bar into the opening on the pallet body and use the hinge locks to secure it as instructed in these steps:
a. Pivot the butterfly handle on the hinge lock up so that it is perpendicular to the body of the hinge lock.
b. Twist the butterfly handle counterclockwise to extend the hinge lock hook to its maximum reach.
c. Lower the hinge lock hook over the hinge lock catch on the pallet body.
d. Twist the butterfly handle clockwise to clamp the hinge lock hook on the hinge lock catch on the pallet body.
e. Pivot the butterfly lever down onto the hinge lock body so that it lies flat.
Step 6 Shift the pallet to ensure that it is positioned evenly all the way around the scissor-jack platform and that the bolt holes in the hold-down brackets on the scissor-jack platform are aligned with the holes in the top of the shipping pallet.
Step 7 Turn the scissor-jack screw slowly clockwise to collapse the scissor-jack platform and lower the top of the scissor-jack platform slowly until the hold-down brackets contact the top of the shipping pallet.
Step 8 Set a blocking plate into the hold-down bracket so that the blank side of the blocking plate is against the heads of the bolts in the side of the scissor-jack platform and the open holes in the blocking plate align with the bolt holes in the top of the pallet.
Step 9 Insert bolts through each of the hold-down bracket holes and into the holes in the top of the shipping pallet, then use the 9/16-inch (14-mm) wrench to tighten the bolts.
Step 10 Turn the scissor-jack screw slowly clockwise to collapse the scissor-jack platform and raise the base of the scissor-jack platform until the weight of the chassis and scissor-jack platform is absorbed by the pallet. Continue turning the scissor-jack screw clockwise to close the scissor-jack platform and lift the base of the scissor-jack platform until it is completely closed (the screw can not be turned).
Repackaging the Chassis for Shipment
To repackage the chassis, use Figure 17 as a reference and follow these steps:
Step 1 Verify that the anchor clips fastening the chassis to the scissor-jack platform are installed correctly and that the bolts are tight.
Step 2 Verify that the bolts fastening the hold-down brackets to the sides of the scissor-jack platform and the top of the pallet are tight.
Step 3 If required, place the accessories package against the back panel of the router on the extended deck of the pallet body.
Step 4 To install the U-shaped, corrugated side panels, use Figure 17 as a reference and follow these steps:
a. Set the long side of one panel on the pallet base such that it sits inside the bead-boards attached to the outside corners of the pallet riser blocks and against the side of the pallet platform.
b. Set the narrow end flaps of the panel inside the bead-boards attached to the outside corners of the pallet riser blocks.
c. Position the opposite U-shaped side panel such that one narrow end flap is inside the narrow end flap of the first U-shaped side panel, while the other narrow end flap is outside the narrow end flap of the first U-shaped side panel.
Note Because the two U-shaped side panels are identical, interlocking them in this fashion maintains the correct overall container dimensions and strength.
Step 5 To fasten the two U-shaped side panels together, use Figure 17 as a reference and follow these steps:
a. Starting at one of the top holes on one narrow side panel, align the holes in the inner and outer corrugated panels.
b. Open a plastic locking clip by pulling the wedge block out of the clip.
c. Insert the clip into the hole, then pivot the wedge block into the opening on the body of the clip and push firmly until it snaps into place, spreading the butterfly tabs and locking the inner and outer side panels together.
Step 6 Set the corrugated top cap on top of the container side panels and push it down.
Step 7 Use a strapping machine to wrap two straps end-to-end and two straps side-to-side over the top of the shipping container to secure it to the pallet.
Step 8 The router is now repackaged and ready to be transported. Use a forklift or pallet jack to move the repackaged chassis.

FCC Class A Compliance
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.
Modifying the equipment without Cisco's authorization may result in the equipment no longer complying with FCC requirements for Class A digital devices. In that event, your right to use the equipment may be limited by FCC regulation and you may be required to correct any interference to radio or television communication at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:
•Turn the television or radio antenna until the interference stops.
•Move the equipment to one side or the other of the television or radio.
•Move the equipment farther away from the television or radio.
•Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

TAC Case Priority Definitions
To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.
Priority 1 (P1)—Your network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
