Maintaining the Router
The Cisco 12006 or Cisco 12406 Router is equipped as ordered and is ready to install and start up when it leaves the factory. After you install and configure the router, you might need to perform other procedures to ensure that the router continues to operate properly. Also, as your networking requirements change, you might need to upgrade your system by adding or changing components.
This chapter describes how to maintain your router. The first section explains when and how to power down the router. The remaining sections describe the following maintenance procedures:
•

•Removing and Installing the Chassis
•Upgrading the RP and Line Card Memory
Before performing the procedures in this chapter, review the safety information in the "Laser Safety" section on page 2-5 and the "Lifting Guidelines" section on page 2-5, and see the Regulatory Compliance and Safety Information for the Cisco 12000 Series Router (Document Number 78-4347-xx), which comes with your router.
Powering Down the Router
Unless otherwise noted, the maintenance tasks described in this chapter can be performed while the router remains powered on. Most Cisco 12006 and Cisco 12406 routers field replaceable units (FRUs) support online insertion and removal (OIR), which means they can be removed and installed (hot-swapped) while the router remains powered up.
•Line cards, switch fabric cards (SFCs), alarm cards, and the blower module are hot-swappable.
•Power modules, clock and scheduler cards (CSCs), and RPs also support OIR, but are hot-swappable only when the system is equipped with two power modules, two CSCs, or two RPs, respectively.
•The power distribution unit (PDU) does not support OIR.
To power down an AC- or a DC-powered router, follow these steps:
Step 1 Turn off the faceplate switches on the power modules.
Step 2 Turn off the facility circuit breakers for power source lines connected to the PDU.
Step 3 When the procedure requires that the router be disconnected from source power:
a. AC-powered systems—Unplug both AC power cords from the power outlets.
b. DC-powered systems—Disconnect and remove the source DC wires from both power connector blocks on the PDU.
Step 4 Verify that the following conditions are true:
a. LEDs on the power modules are off, and power module fans are off.
b. LEDs on the RP, line cards, and alarm cards are off.
c. LEDs on the blower module are off, and all blower module fans are off.
Removing and Installing the Front Door on Cisco 12006 and Cisco 12406 Enhanced Series Router
The Cisco 12006 and Cisco 12406 enhanced series routers have a new 1-piece front door. The router ships with the door hinge mounted on the left side of the chassis so that it opens from right-to-left. This section describes how to change the front door to open from left-to-right by installing the hinge on the opposite side.
Use the following procedure to change the location of the hinge.
Step 1 Open the front door by pressing the right latch button (Figure 6-1).
Figure 6-1 Opening the Front Door
Step 2 Remove the front door by lifting the (top and bottom) hinge pins to free the door from the chassis (Figure 6-2).
Caution Make sure you are holding the front door securely so it does not drop when you release it from the chassis.
Step 3 Reinstall the hinge pins into the chassis hinge brackets.
Figure 6-2 Removing or Installing Hinge Pins
Step 4 Remove the bumpers and pivot blocks from the door as shown in Figure 6-3.
Figure 6-3 Removing the Bumpers and Pivot Blocks
Step 5 Reinstall the hardware to the opposite sides of the front door:
a. Mount pivot blocks to the left side and tighten the screws until snug.
b. Mount the bumpers to the right side and tighten the screws until snug.
Step 6 Attach the front door to the chassis:
a. Remove the hinge pins from the hinges on the right side of the chassis.
b. Align the pivot blocks on the front door with the hinges on the right side of the chassis and install the hinge pins to hold the door in place (see Figure 6-2).
c. Close the front door by pressing the latch button allowing the door latch to engage with the hinge pins on the chassis.
Cleaning or Replacing the Air Filters
The Cisco 12006 and Cisco 12406 routers are equipped with two user-serviceable air filters that remove dust drawn into the router by the blower module. One time per month (or more often in dusty environments), examine the air filters.
Use the following procedure to clean or replace the air filters.
Step 1 Open the spring-loaded air filter door on the right side of the chassis and remove an air filter by pulling the small tab on the edge of the filter (Figure 6-4).
Remove the second air filter the same way.
Figure 6-4 Removing the Air Filters

Step 2 Visually check the condition of the air filters to determine whether to clean them or install new replacements.
•Dirty—You can vacuum or replace the filters.
Caution Do not try to vacuum the air filter while it is installed in the chassis. You must remove the air filter completely before you clean it to prevent contaminants from being drawn into the router.
•Worn or torn—If the filters appear worn or torn, dispose of them in a responsible manner and install replacement air filters (ACS-GSR6-FLTR=).
Step 3 Open the air filter door and install the new or cleaned air filters.
Note An arrow located on the edge of each air filter frame that indicates the direction of air flow. Always install the air filter with the arrow pointing in toward the RP and line card cage.
Removing and Replacing the Blower Module
The illustrations in this procedure represent both the original and newer enhanced capacity blower modules for the Cisco 12006 and Cisco 12406 series routers; blowers that shipped with original systems, and enhanced capacity blowers that ship with current systems. If you are replacing an:
•Original blower module (GSR6-BLOWER=)—Use an original blower module or an enhanced capacity blower module as a replacement.
•Enhanced capacity blower module (12000/6-BLOWER=)—Use an enhanced capacity blower module as a replacement.
Note Compared to the original blower modules that shipped with Cisco 12006 and Cisco 12406 series routers, airflow capacity for new enhanced blower modules is increased by nearly 40 percent to provide additional cooling to the chassis. The new fans operate at a higher speed to provide improved airflow, so you may notice increased sound generated from the new blower module.
Use the following procedure to remove and replace the blower module.
Step 1 Remove the blower module from the chassis (Figure 6-5):
a. Lift the blower module handle to its carrying position.
b. Loosen the four captive screws on the blower module faceplate.
c. Remove the blower module by grasping it on each side and pulling it straight back from the chassis.
Figure 6-5 Removing the Blower Module

Step 2 Install the new blower module (Figure 6-6):
a. Position the alignment holes on the blower module with the guide pins at the top of the chassis and on the PDU at the bottom of the chassis.
b. Slide the blower toward the chassis until it mates with the backplane connector.
Caution Electrical and control line connections for the blower module and backplane occur automatically when the connectors on the blower module and PDU mate. To prevent damage to the blower module and PDU connectors, do not use excessive force when installing the blower module against the rear of the chassis.
c. Tighten the four captive screws to secure the blower module to the chassis.
The (green) OK indicator should light. If the OK indicator does not light, see the "Troubleshooting the Blower Installation" section.
d. Lower the blower module handle to its operating position.

Troubleshooting the Blower Installation
Use the following procedure to troubleshoot the blower module if it is not operating properly after installation.
Step 1 Be sure the router is powered on and that all power cords are connected properly.
Step 2 Loosen the four captive screws and reseat the blower module to the chassis. Retighten the captive screws to ensure the blower module is properly seated to the backplane connector.
Step 3 Check the blower module status indicators:
•OK (green)—This indicator should light as soon as the blower module is installed and receives power from the backplane connector. It indicates that the blower module is operating normally.
•Fail (red)—This indicator remains off during normal operation. If the indicator is on, the system has detected a fan failure or other fault in the blower module.
–If this indicator remains on and the blower module fans fail to operate normally after several attempts to reseat the blower module, replace the existing blower module with a spare.
–If the spare blower module also fails, power off the router and contact a Cisco service representative for assistance.
Removing and Replacing AC and DC Power Subsystem Components
This section contains removal and replacement procedures for the AC and DC power systems used with the Cisco 12006 and Cisco 12406 series routers. If you ordered an upgrade kit, you can use these same procedures to upgrade all of the power system components.
The illustrations in this procedure represent both original and upgraded power supplies and PDUs shipping with the Cisco 12006 and Cisco 12406 series routers. Depending on your system, these components may not look exactly like those in your chassis, but the removal and replacement procedures are essentially the same. Multiple illustrations are presented to represent original and new models where appropriate.
The following tools and equipment are required to remove and install power equipment:
•Number 1 Phillips screwdriver
•3/16-inch flat-blade screwdriver
•An ESD-preventive wrist strap
Installation Guidelines
The Cisco 12006 and Cisco 12406 series routers support online insertion and removal (OIR). If you are replacing a redundant power supply, you can remove and install the power supply while the system remains powered on without causing an electrical hazard or damage to the system. This feature enables you replace a power supply while the system maintains all routing information and ensures session preservation.
However, to maintain operational redundancy, proper cooling, and meet EMI compliance standards, you must have both working power supplies installed. When you remove a failed power supply with the router in operation, perform the replacement as quickly as possible. Make sure you have the tools and the replacement power supply ready before beginning the removal and installation procedure.
Power Supply and PDU Compatibility
Cisco 12006 and Cisco 12406 series routers are available with either an AC or DC power supply system. The two types of power supplies for these systems are:
•Original power supplies (rated at 1400 watts) that shipped with earlier systems
•Enhanced capacity power supplies (rated at 1900 watts) that ship with current systems and upgrade kits
Removal and replacement procedures are the same for either type of power supply, but because of their power capacity and physical differences, you cannot mix different types of power supplies in the chassis.
Caution Newer, 1900 W DC power supplies require the upgraded PDU. You cannot install a new power supply using the old PDU. If you are replacing an old power supply with the new unit, you must perform a complete upgrade by replacing both power supplies, the PDU,
and the blower module if you are required to meet NEBS extended temperature range requirements. This also means that you must shut down the router to perform the upgrade. Notify the system administrator and other appropriate personnel that all routing traffic stops while the upgrade takes place.
Before you attempt to install or replace them (Table 6-1Table 6-1), be sure you know your system power supplies and associated PDU.

Removing and Installing an RP or a Line Card
Line cards can occupy any slot, slot 0 (the top slot) through slot 4, in the RP and line card cage. (See Figure 6-27.) Your Cisco 12006 or Cisco 12406 Router is configured with the RP in slot 5 (the bottom slot). A redundant RP can be installed in any slot. The redundant RP requires a line card spacer to comply with EMI emission standards.
Figure 6-27 Cisco 12006 and Cisco 12406 routers Card Cage Slot Locations
Additional line card information can be found in the installation and configuration note for each type of line card. These notes accompany every line card that ships from the factory as an FRU.
Tools and Equipment
To remove and replace a line card, you need the following items:
•ESD-preventive strap
•3/16-inch flat-blade screwdriver
•Replacement line card or RP
Removing an RP or Line Card
Cisco 12000 Series line cards support OIR, so they can be removed and installed while the router remains powered up. RPs also support OIR, but are hot-swappable only when the system is equipped with two RPs.
To remove an RP or line card from the RP and line card cage, see Figure 6-28 and follow these steps:
Step 1 Attach an ESD-preventive strap to your wrist and connect the leash to the chassis or to another grounded, bare metal surface.
Step 2 Identify the line card to be replaced and write down the following information:
•The slot number and type of line card
•The network interface cable connection ports on the line card
Step 3 On cards with multiple ports, start with the left port on the card and disconnect the interface cable connectors from each of the ports.
Step 4 After all the interface cables are disconnected, loosen the two captive screws on the cable-management bracket and pull the bracket away from the card.
Step 5 Loosen the two ejector lever captive screws at each end of the line card faceplate.
Step 6 Simultaneously pivot the ejector levers away from each other to unseat the line card from the backplane connector. Rotate each ejector lever outward away from the faceplate. (See Figure 6-28.)
Caution Fully remove each line card from its slot. Do not allow a line card to rest partially inserted into a slot, because that will damage the EMI shielding on the RP or line card in the slot directly below.
Figure 6-28 Removing an RP or Line Card from the Card Cage
Step 7 Grasp the edges of the line card carrier with both hands to support it, and fully remove the line card from the slot.
Caution One edge of the card carrier faceplate is lined with an EMI-preventive gasket consisting of many raised, conductive contacts. Be careful not to damage the gasket contacts, because a damaged card carrier gasket can reduce EMI performance.
Step 8 Immediately place the line card in an antistatic bag to protect it against ESD and to prevent dust from getting to the fiber-optic connectors on fiber-optic line cards.
Note If a line card slot in the card cage is not populated with a line card, a blank line card must be installed to avoid overheating and to ensure electromagnetic compliance (EMC).
If you plan to return the defective line card to the factory, repackage it in the shipping container you received with the replacement line card.
Installing an RP or Line Card
To install a line card in the RP and line card cage, follow these steps:
Step 1 Attach an ESD-preventive strap to your wrist and connect the leash to the chassis or to another grounded, bare metal surface.
Step 2 Check the slot assignment and network interface cable information that you wrote down before you removed the other RP or line card.
Caution Handle the RP or line cards by the metal card carrier edges only; avoid touching the board itself or any connector pins.
Step 3 Remove the RP or line card from its shipping package and antistatic bag.
Step 4 Set both edges of the RP or line card carrier into the card slot carrier alignment grooves on either side of the card cage.
Caution Do not allow a line card to rest partially inserted into a slot, because that will damage the EMI shielding on the RP or line card in the slot directly below.
Step 5 Pivot the ejector levers away from each other; rotate each ejector lever outward away from the faceplate.
Step 6 Grasp the edges of the metal card carrier with both hands to support and guide the RP or line card into the slot alignment grooves in the card cage.
Caution One edge of the card carrier faceplate is lined with an EMI-preventive gasket consisting of many raised, conductive contacts. Be careful not to damage the gasket contacts, because a damaged card carrier gasket can reduce EMI performance.
Step 7 Use both thumbs to slide the card carrier into the RP and line card slots until the ejector levers make contact with the front of the card cage, then stop.
Step 8 Grasp the two RP or line card ejector levers and pivot them toward the card faceplate until they are perpendicular to the faceplate, to seat the RP or line card in the backplane connector.
Step 9 Tighten the captive screws on each side of the card faceplate to prevent the RP or line card from becoming partially dislodged from the backplane and to ensure proper EMI shielding.
Note The line card captive screws must be tightened to meet EMI specification standards.
Repeat Step 2 through Step 9 for any additional replacement RPs or line cards, then proceed to the "Reconnecting Cables to a Line Card" section.
Adding an RP or Line Card
To install a new RP or line card in the RP and line card cage, follow these steps:
Step 1 Attach an ESD-preventive strap to your wrist and connect the leash to the chassis or to another grounded, bare metal surface.
Step 2 Identify the card slot for the new line card.
Step 3 Remove the blank faceplate covering the card slot.
Step 4 If installed, remove the narrow card filler panel at the top of the blank card slot.
Caution Handle line cards by the metal card carrier edges only; avoid touching the board itself or any connector pins.
Step 5 Go to Step 3 of the procedure "Installing an RP or Line Card" on page 6-50 to continue the installation of an RP or line card.
Step 6 Repeat Step 2 through Step 5 for any additional card installations.
Note If a line card slot in the card cage is not populated with a line card, a blank line card must be installed to avoid overheating and to ensure electromagnetic compliance (EMC).
Installing a Line Card Cable-Management Bracket
When you install a new line card, you must install the line card cable-management bracket on the faceplate of the line card before connecting cables to the ports. Figure 6-29 shows a typical line card cable-management bracket oriented and aligned for installation on a line card in a Cisco 12006 or Cisco 12406 Router.
Figure 6-29 Line Card Cable-Management Bracket
The Cisco 12000 Series Router line cards use cable-management brackets for the following purposes:
•Organizing the network interface cables
•Keeping the network interface cables out of the way
•Positioning connectors at their respective ports on the line card faceplate
•Keeping the cables free of sharp bends (excessive bending in a network interface cable can cause performance degradation)
Note The type of cable-management bracket used by a line card is determined by the line card type and the number of network interface ports on the card faceplate.
To install the line card cable-management bracket, see Figure 6-29 and follow these steps:
Step 1 Attach an ESD-preventive strap to your wrist and connect the leash to the chassis or to another grounded, bare metal surface.
Step 2 Take the line card cable-management bracket from the line card shipping carton.
Step 3 Orient the top of the line card cable-management bracket with the top of the line card faceplate (the end opposite the two four-character alphanumeric displays.)
