•Have access to the following documents during the installation:
–Regulatory Compliance and Safety Information for Cisco 12000 Series Routers publication that shipped with the router (PN 78-4347-xx)
Powering Off the Router
Most Cisco 12010, Cisco 12410, and Cisco 12810 series routers field-replaceable units (FRUs) can be removed and replaced with the power on and the system operating. This is known as online insertion and removal (OIR). Power supplies, line cards, the RP, CSCs, SFCs, and alarm cards all support OIR. Unless otherwise noted, the maintenance tasks described in this chapter can be performed while the router remains powered on.
In some cases it may be necessary to power off the router, for example, to upgrade both power supplies and PDUs. Use the following procedure to power off the router.
Step 1 Set the power switch on each power supply to the off (0) position.
Step 2 Power off all circuit breakers for the source power lines connected to the power supplies.
Step 3 Verify that the Pwr OK indicator on each power supply is off.
Step 4 Verify that the OK indicator on the blower module is off.
Removing and Installing the Front Covers and Bezel Extenders on Original Cisco 12010 Series Routers
The front covers are fastened to the chassis by ball studs that insert into clips on the front of the chassis. The front covers are referred to as snap-on front covers.
The partial front cover on the air filter door is fastened to the air filter door by four screws inserted from the back side of the air filter door. This partial front cover is referred to as the air filter door front cover.
Note Recently released routers have bezel extenders installed on the front cover (bezel) for the line card and route processor (RP) card cage to bring the cover out an additional 2 inches (50.8 mm) to allow more room for cables. If your chassis does not have these extenders and you want to purchase them, contact Cisco sales. (See the "Attaching Bezel Extenders to the Front Cover" section if you are installing the bezel extenders.)
Removing the Front Covers
The front covers are held in place by ball studs that snap into clips on the chassis. Refer to Figure 7-1 and use the following procedure to remove the snap-on front covers.
Step 1 Grasp the outside edges of the blower module front cover and pull it straight out to detach the front cover from the chassis.
Step 2 Repeat Step 1 for the RP and line card cage front cover.
Installing the Front Covers
Refer to Figure 7-1 and use the following procedure to install the front covers.
Step 1 Hold the front cover by its outside edges and align the ball studs with the ball stud clips on the front of the chassis.
Step 2 Push the front cover into the ball stud clips and the front cover is flush with the front of the chassis.
Step 3 Repeat Step 1 and Step 2 for the remaining front cover.
Figure 7-1 Removing and Installing the Front Covers
Attaching Bezel Extenders to the Front Cover
Use the following procedure to attach the bezel extenders to the card cage front cover.
Step 1 Remove the line card and RP card cage front cover from the chassis as described in the "Removing the Front Covers" section.
Step 2 Remove the four ball studs from the front cover (Figure 7-2, item 3).
Step 3 Screw the four ball studs into the threaded holes on the bezel extenders (two ball studs for each bezel extender) using a wrench to secure them.
Caution Do not overtighten the ball studs. Overtightening the ball studs could damage the threaded hole on the bezel extender.
Step 4 Attach the bezel extenders to the front cover:
a. Facing the inside of the front cover, align the screw holes in the left side bezel extender with the mounting screw holes in the front cover (Figure 7-2, item 4).
Note If you cannot align both screw holes on the front cover inserts, you have the incorrect bezel extender. Try the other bezel extender on this side.
b. Fasten the bezel extender to the front cover with the mounting screws (Figure 7-2, item 2).
Caution Do not overtighten the screws. Overtightening the screws could damage the threaded holes in the front cover.
c. Repeat Steps a and b to fasten the right side bezel extender to the other side of the front cover (Figure 7-2, item 5).

Cleaning or Replacing the Chassis Air Filter
The Cisco 12010, Cisco 12410, and Cisco 12810 series routers are equipped with a user-serviceable air filter that prevents dust from being drawn into the router. One time per month (or more often in dusty environments), examine the air filter for damage and cleanliness.
Caution Damage to the air filter can restrict the airflow, cause overheating in the router, and degrade EMI performance. Be careful when cleaning and replacing the filter.
The following procedures describe how to replace the air filter on original series routers and enhanced series routers.
•Cleaning or Replacing an Original Series Chassis Air Filter
•Cleaning or Replacing an Enhanced Series Chassis Air Filter
Cleaning or Replacing an Original Series Chassis Air Filter
Use the following procedure to clean or replace an original series air filter.
Step 1 Loosen the captive screw on each side of the air filter door and pivot open the door (Figure 7-9).
Figure 7-9 Opening the Chassis Air Filter Door
Step 2 Remove the air filter by pushing it up and out of the door (Figure 7-10).
Caution Be careful not to damage the honeycomb screens on the back of the air filter door and in the fabric card cage. Damage to the honeycomb screens can restrict airflow, cause overheating, and affect EMI performance.
Note Your air filter may have small tabs located on the top of the filter that you can use to pull the air filter out of the door.
Figure 7-10 Removing the Chassis Air Filter
Step 3 Visually check the condition of the air filter to determine whether to clean it or install a new replacement filter:
•Dirty—You can either vacuum or replace the filter.
Caution Do not vacuum the air filter while it is installed in the chassis. Before you clean it, you must remove the air filter completely to prevent contaminants from being drawn into the router.
•Worn or torn—If the filter appears worn or torn, dispose of it in a responsible manner and install a new replacement (ACS-GSR10-FLTR=).
Step 4 Slide the new or cleaned air filter into the air filter door.
•The metal braces on the back of the air filter should face toward the switch fabric and alarm card cage.
Step 5 Close the air filter door and tighten the captive screws.
Caution Align and seat the door carefully to avoid damaging the EMI-preventive gaskets on the door. The air filter door must be closed and secured at all times to maintain correct EMI performance.
Cleaning or Replacing an Enhanced Series Chassis Air Filter

Step 1 Loosen the captive screw on each side of the air filter door and pivot the door open (Figure 7-11).
Figure 7-11 Opening the Chassis Air Filter Door
Step 2 Remove the air filter by sliding it out of the door (Figure 7-12).
Figure 7-12 Removing the Chassis Air Filter
Step 3 Visually check the condition of the air filter to determine whether to clean it or install a new replacement filter:
•Dirty—You can either vacuum or replace the filter.
Caution Do not vacuum the air filter while it is installed in the chassis. Before you clean it, you must remove the air filter completely to prevent contaminants from being drawn into the router.
•Worn or torn—If the filter appears worn or torn, dispose of it in a responsible manner and install a new replacement (12000/10-FILTER=).
Step 4 Slide the new or cleaned air filter into the air filter door (honey comb side down).
Step 5 Close the air filter door and tighten the captive screws (see Figure 7-11).
Caution Align and seat the door carefully to avoid damaging the EMI-preventive gaskets on the door. The air filter door must be closed and secured at all times to maintain correct EMI performance.
Removing and Replacing the Blower Module
The illustrations in this procedure represent both the original and newer enhanced capacity blower modules for the Cisco 12010, Cisco 12410, and Cisco 12810 series routers. Depending on your system, the blower module shown may not look exactly like the one in your chassis, but the removal and replacement procedures are essentially the same.
There are currently two types of blower modules in use for the Cisco 12010, Cisco 12410, and Cisco 12810 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 (GSR10-BLOWER=)—Use an original blower module or an enhanced capacity blower module as a replacement.
•Enhanced capacity blower module (12000/10/16-BLWER=)—Use an enhanced capacity blower module as a replacement.
Note If you upgraded your router with a power supply upgrade kit (2800 W PEMs) and your system is required to meet NEBS extended temperature range requirements, you must install the enhanced capacity blower module (12000/10/16-BLWER=) to meet those requirements.
Use the following procedure to remove and replace the blower module.
Step 1 Remove the blower module from the chassis (Figure 7-13):
a. Loosen the captive screw on each side of the blower module.
b. Pull the blower module halfway out of the module bay.
c. Slide out the blower module completely from the module bay while supporting it with your other hand.
Warning The blower module weighs approximately 20 pounds (9 kg). Use two hands when handling the blower module.
Figure 7-13 Removing the Blower Module
Step 2 Install the new blower module into the chassis (Figure 7-14):
a. Lift the blower module (with two hands) and slide it halfway into the module bay.
b. Slowly push the blower module into the chassis until it mates with the backplane connector at the back of the module bay.
Caution To prevent damage to the connectors, do not use excessive force when inserting the blower module into the chassis.
c. Tighten the captive screws on the blower module to secure it to the chassis.
•The (green) OK status indicator on the front of the blower module goes on. If the OK indicator does not light, see the "Troubleshooting the Blower Module Installation" section.
Figure 7-14 Installing the Blower Module
Troubleshooting the Blower Module 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 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)—Indicates that the blower module is operating normally. This indicator should light as soon as the blower module is installed and receives power from the backplane connector.
–If this indicator remains on, and the blower module fans fail to operate after several attempts to reseat the blower module, replace it with a spare.
–If the spare blower module also fails, power off the router and contact a Cisco service representative for assistance.
•Fail (red)—This indicator remains off during normal operation. If this 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 after several attempts to reseat the blower module, replace it 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 12010, Cisco 12410, and Cisco 12810 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 12010, Cisco 12410, and Cisco 12810 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 12010, Cisco 12410, and Cisco 12810 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. Before you begin the removal and installation procedure, make sure you have the tools and the replacement power supply ready.
Caution You cannot mix power supply types within the chassis. If you are replacing a 2400 W power supply from an older system with a newer 2800 W power supply, you must replace both power supplies and the PDUs (see
Table 7-1). You must shut down the router to perform the upgrade. Be sure to notify the appropriate personnel that all routing traffic stops while the upgrade takes place.
Caution Cisco 12010, Cisco 12410, and Cisco 12810 series routers configured with non-enhanced fabric and a single power supply and with more than five Engine5 line-cards may fail to boot during the start-up procedures. To safeguard against this possibility ensure that the chassis is configured with two power supplies or configured with the enhanced fabric.
Power Supply and Power Distribution Unit Compatibility
Cisco 12010, Cisco 12410, and Cisco 12810 series routers are available with either an AC or DC power supply system. There are currently two types of power supplies in use for these systems:
•Original power supplies (rated at 2400 watts)—Shipped with original systems
•Enhanced capacity power supplies (rated at 2800 watts)—Ships currently
Removal and replacement procedures are the same for either type of power supply. Because of their capacity and physical differences, you cannot mix different types of power supplies in the chassis. Power supplies are also referred to as Power Entry Modules (PEMs).
Enhanced capacity 2800 W PEMs also require upgrades to new Power Distribution Units (PDUs). You cannot install enhanced capacity PEMs using the original PDUs. If you plan to replace original PEMs with enhanced PEMs, you must replace both the PEMs and the PDUs.
Before you attempt to install or replace them, be sure you know the power supplies and associated PDUs your system has (Table 7-1).

Use the following procedure to remove and replace a DC PEM.
Caution You cannot mix PEM types within the chassis. If you are replacing a 2400 W PEM from an old system with a new, 2800 W PEM, you must replace both the PEMs
and the DC PDUs (see
Table 7-1). You must shut down the router to perform the upgrade. Be sure to notify the system administrator and other appropriate personnel that all routing traffic stops while the upgrade takes place.
Step 1 Set the power switch to the off (0) position.
Step 2 Power off the circuit breaker assigned to the PEM you are removing.
Warning To ensure that power remains off while you are performing this procedure, tape the circuit breaker switch in the off (0) position.
Step 3 Remove the PEM from the chassis (Figure 7-24):
a. Loosen the captive screw on the ejector lever.
b. Pivot the lever down to eject the PEM from its bay.
c. Slide the PEM out of its bay while supporting it with your other hand.
Warning The DC PEM weighs approximately 14 pounds (6.35 kg). Use two hands to remove the power supply.
Figure 7-24 Removing a DC PEM
Step 4 Install the new DC PEM into the chassis (Figure 7-25):
a. Slowly push the power supply into the chassis until it mates with the backplane connector at the back of the bay.
Caution To prevent damage to the power shelf backplane connector, do not use excessive force when inserting a power supply into the chassis.
b. Lift the ejector lever into place and tighten the captive screw to securely seat the power supply to the backplane connector.

Step 5 Power on the circuit breaker.
Step 6 Set the power switch to the on (1) position.
The (green) Pwr OK indicator on the front of the power supply should light. If the indicator does not light, see the "Troubleshooting a 2400 W DC PEM Installation" section, or the "Troubleshooting a 2800 W DC PEM Installation" section.
Troubleshooting a 2400 W DC PEM Installation
Use the following procedure to troubleshoot the DC PEM if it is not operating properly after installation.
Step 1 Make sure the PEM is seated properly:
•Eject and reseat the PEM. Make sure:
–The captive screw on the ejector lever is tightened securely.
–The power switch is set to the on (1) position.
Step 2 Make sure the router is powered on and that all power cords are connected properly:
•Power cords on the back panel are attached securely to their terminal studs.
•Power cords are securely attached at the DC source end.
•The source DC circuit breaker is switched on.
Step 3 Check the PEM status indicators:
•Pwr OK (green)—Indicates that the PEM is operating normally, and the source DC voltage is within the nominal operating range of -48 to -60 VDC. This indicator lights when the power switch is set to the on (1) position.
•Fault (yellow)—Indicates that the system detected a fault within the PEM. This indicator remains off during normal operation.
–Toggle the power switch off and then on. If the indicator remains on after several attempts to power it on, replace the existing PEM with a spare.
–If the spare PEM also fails, the problem could be a faulty power shelf backplane connector. Power off the router and contact a Cisco service representative for assistance.
•Temp (yellow)—Indicates that the PEM is in an overtemperature condition causing a shut-down to occur.
–Verify that the power supply fan is operating properly.
–Verify that the blower module is operating properly.
–If the power supply fan and blower module are operating properly, replace the existing PEM with a spare.
Troubleshooting a 2800 W DC PEM Installation
Use the following procedure to troubleshoot the DC PEM if it is not operating properly after installation.
Step 1 Make sure the PEM is seated properly:
•Eject and reseat the PEM. Make sure:
–The captive screw on the ejector lever is tightened securely.
–The power switch is set to the on (1) position.
Step 2 Make sure the router is powered on and that all power cords are connected properly.
Step 3 Check the PEM status indicators:
•F1LO (Feeder 1 Low) (flashing yellow)—Indicates that input connections to the PDU (Feeder 1) were removed, or the input voltage is below the minimum. Make sure that:
–Power cords are securely attached to their PDU terminal studs.
–Power cords are securely attached at the DC source end.
–The source DC circuit breaker is switched on.
If the indicator is still flashing after you perform the above checks, replace the power supply.
During normal operation, this indicator remains off.
•F2LO (Feeder2 Low) (flashing yellow)—Indicates that input connections to the PDU (Feeder 2) are removed or the input voltage is below the minimum. Make sure that:
–Power cords are securely attached to their PDU terminal studs.
–Power cords are securely attached at the DC source end.
–The source DC circuit breaker is switched on.
If the indicator is still flashing after you perform the above checks, replace the power supply.
During normal operation, this indicator remains off.
•RPF1 (Reverse Polarity Feeder 1) (flashing yellow)—The PDU (Feeder 1) is miswired. See Step 12 of the "Removing and Replacing a DC PDU" procedure. During normal operation, this indicator remains off.
•RP21(Reverse Polarity Feeder 2) (flashing yellow)—The PDU (Feeder 2) is mis-wired. See Step 12 of the "Removing and Replacing a DC PDU" procedure. During normal operation, this indicator remains off.
•Fail (red)—Lights in conjunction with the following indicators (which flash) to show the type of power supply failure:
–F1LO
–F2LO
–OC
–OT
•OC (Over Current) (flashing red)—Indicates the input or output current has exceeded its limit and that an overload or short circuit has occurred:
–Set the power supply switch to off (0) and then back to the on (1) position.
–If the indicator is still flashing, eject and reseat the power supply.
–If the indicator is still flashing, replace the power supply.
•OT (Over Temperature) (steady or flashing red)—Indicates that the power supply is in an overtemperature condition, causing a shut-down to occur.
–Flashing red—Indicates a locked power supply fan. Replace the power supply.
–Steady red—Indicates an overtemperature condition. Verify that all fans in the blower module are operating properly.
•If all the blower module fans function, replace the power supply.
•If one or more of the blower module fans do not work, refer to the Cisco 12010, Cisco 12410, and Cisco 12810 Router Blower Module and Air Filter Replacement Instructions (PN 78-15875=) for instructions to replace the blower module.
•INOK (green)—Indicates that the power supply is operating normally, and the source DC voltage is within the nominal operating range of -48 to -60 VDC. This indicator lights when the power switch is set to the on (1) position. If there is a power supply failure, the INOK indicator shuts off.
•DCOK (green)—Indicates that the power supply is operating normally, and is within the nominal operating range. This indicator lights a few seconds after the DCOK indicator lights. If there is a power supply failure, the INOK indicator shuts off.
