Product Overview

The Cisco 12012 has two card cages; the upper card cage and the lower card cage. (Refer to Figure 1.) The upper card cage has 12 user-configurable slots available for line cards and a route processor (RP). One additional slot (rightmost slot) in the upper card cage is non-configurable; it is reserved for an alarm card. The line cards and the RP are not slot dependent; you can install the line cards and the RP in any of the first 12 available slots.

Figure 1 Cisco 12012—Front View

The lower card cage, located behind the air filter, has five keyed horizontal slots for cards containing the switch fabric circuitry. The cards provide the physical pathway for data packet exchange between the line cards in the upper card cage.

There are two types of cards installed in the lower card cage; the clock and scheduler card (CSC) and the switch fabric card (SFC). Both types of cards are keyed to fit into specific slots in the lower card cage. You can install the clock and scheduler card only in the top two slots and the switch fabric card only in the lower three slots. The clock and scheduler card contains the system clock, switch fabric scheduler circuitry, and the switch fabric. The switch fabric card contains only switch fabric circuitry.

Below the lower card cage is a power supply bay. The Cisco 12012 can be configured for source AC or source DC operation. A system configured for source AC operation must have a minimum of two AC-input power supplies installed. You can install two additional AC-input power supplies for redundancy and current sharing. Systems configured for source DC operation have one DC-input power supply installed. You can install a second DC-input power supply for redundancy and current sharing.

The Cisco 12012 has two blower modules; one located above the upper card cage and one located below the power supply bay. They draw filtered cooling air in through both card cages and the power supply bay to maintain acceptable operating temperatures for the internal components.

Safety Guidelines

Before you begin the replacement procedure, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment. This section also repeats in multiple languages the warnings in this document.

In addition, review the safety warnings listed in the document Regulatory Compliance and Safety Information for the Cisco 12012 Gigabit Switch Router (Document Number 78-4347-xx) that supports your Cisco 12012 before installing, configuring, or maintaining the router.

Safety with Equipment

The following guidelines will help ensure your safety and protect the equipment. This list is not inclusive of all potentially hazardous situations, so be alert.

Always disconnect all power cords and interface cables before moving the system.

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

The line cards, RP, switch fabric cards, blower modules, and redundant power supplies are designed to be removed and replaced while the system is operating without presenting an electrical hazard or damage to the system.

Follow these basic guidelines when working with any electrical equipment:

Before beginning any procedures requiring access to the interior of the Cisco 12012, locate the emergency power-off switch for the room in which you are working.

Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, and missing safety grounds.

If an electrical accident occurs, proceed as follows:

Use caution; do not become a victim yourself. Disconnect power to the system.

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.

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.

In addition, use the guidelines that follow 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

Electrostatic discharge damage, which can occur when electronic boards or components are handled improperly, can result in complete or intermittent failures.

Following are guidelines for preventing ESD damage:

Always use an ESD-preventive wrist strap or ankle strap and ensure that it makes good skin contact.

When removing or installing a component, connect the equipment end of a ground strap to one of the two ESD ground sockets located on the front sides of the upper card cage or to a bare metal surface on the frame.

If you plan to return a replaced component to the factory, immediately place it in a static shielding bag to avoid ESD damage to the component.

The wrist strap only protects the component from ESD voltages on the body; ESD voltages on clothing can still cause damage.


Caution   
You should periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms.

Tools and Parts Required

You need the following tools and parts to remove and replace the card cage assembly:

ESD-preventive wrist strap

1/4-inch flat-blade screwdriver

3/16-inch flat-blade screwdriver

Perform the following steps to replace the alarm card in the upper card cage:


Step 1 Attach an antistatic wrist strap to yourself and to one of the two ESD connection sockets located on the front edges of the upper card cage or to bare metal on the frame.

Step 2 Grasp the alarm card faceplate with one hand and place your other hand under the card carrier to support and guide it into the card cage slot labeled alarm card.

Step 3 Carefully slide the alarm card carrier into the slot until it makes contact with the backplane connector, then stop. Avoid touching the card circuitry or any connectors.

Step 4 Carefully push on the top and bottom of the alarm card to seat it in the backplane connector.

Step 5 Tighten the two captive screws to secure the alarm card in the upper card cage slot.

Step 6 Connect any external devices to their respective connectors on the alarm card

Installing the System Grounding

Your system might have two system grounding cable lugs. The system grounding receptacles are located on the card cage assembly side flanges between the air filter tray and the power supply bay. (Refer to Figure 12.)

Perform the following steps to install the system grounding lugs to the card cage assembly:


Step 1 Position the system ground lug over the card cage assembly system grounding receptacle.

Step 2 Secure the system grounding lug to the receptacle with two sets of screws, washers, and nuts. (Refer to Figure 13.)

Repeat Step 1 and Step 2 for a second system grounding connection.

Replacing the Power Supplies

This section provides procedures for replacing an AC-input power supply and a DC-input power supply. Select the procedure appropriate for your system.


Caution   
Always wear an antistatic wrist strap to prevent ESD when removing and replacing a power supply.

Replacing an AC-Input Power Supply

Perform the following steps to replace an AC-input power supply:


Step 1 Attach an antistatic wrist strap to yourself and to one of the two ESD connection sockets located on the front edges of the upper card cage or to bare metal on the frame.

Step 2 Verify that the power switch on the power supply is in the STANDBY position.


Caution   
To prevent damaging the power supply backplane connector, do not use excessive force when installing a power supply into the bay.


Note   The power supply bay positions are designated A1, A2, B1, and B2, from left to right. Install power supplies in the bay in the following order: A1, B1, A2, and B2. Any power supply bay position that does not have a power supply installed must have a power supply blank installed to maintain airflow and for EMI considerations.


Step 3 Using two hands to support and guide the power supply, slide it into the vacant power supply bay position. Push the power supply all the way into the power supply bay until the faceplate makes contact with the front of the bay.


Note   All electrical connections between the power supply and the backplane are made automatically when the power supply is fully inserted in the power supply bay.


Step 4 Tighten the captive screw on the power supply faceplate.

Step 5 Connect the AC power cord to the power supply AC receptacle. Clip the spring clip over the power cord plug.

Step 6 Connect the other end of the AC power cord to the source AC receptacle.


Note   Do not turn on the power supply power switch at this time.


Repeat Step 2 through Step 6 for the rest of the AC-input power supplies.

Step 7 Verify that any empty power supply bay slots have power supply blanks installed.

Proceed to the section "Checking the Installation" to verify the installation

Replacing a DC-Input Power Supply

Perform the following steps to replace a DC-input power supply:


Step 1 Attach an antistatic wrist strap to yourself and to one of the two ESD connection sockets located on the front edges of the upper card cage or to bare metal on the frame.


Caution   
To prevent damaging the power supply backplane connector, do not use excessive force when installing a power supply into the bay.

Step 2 Verify that the power switch on the power supply is in the OFF position.

Step 3 Using two hands to support and guide the power supply, carefully slide it into the vacant bay. (Refer to Figure 16.) Stop when the power supply captive jackscrew makes contact with the front of the power supply bay.

Figure 16 Installing a DC-Input Power Supply


Note   The captive jackscrew is used to align and draw the power supply connector into the backplane connector. To prevent connector alignment problems, apply even pressure on the power supply handle as you turn the captive jackscrew.


Step 4 Keep one hand on the power supply handle and apply even pressure to the power supply as you turn the captive jackscrew clockwise (insert) using a 10-mm nutdriver or flat-blade screwdriver. Do not overtighten the jackscrew.


Note   All electrical connections between the power supply and the backplane are made automatically when the power supply is fully inserted in the power supply bay.


Repeat Step 2 through Step 4 for a second DC-input power supply.

Step 5 Turn on the source DC circuit breaker servicing the DC-input power supply. Do not turn on the power supply power switch at this time.

Proceed to the next section to verify the installation

Checking the Installation

To complete the installation, perform a check of all connections, then power up the system.

Follow these steps to restart the system and verify that the system restarts successfully:


Step 1 Check the following components to make sure they are secure:

Line cards are fully inserted in the slots and all captive screws are tightened.

Vertical cable brackets are attached to their respective line cards and all captive screws are tightened.

Interface cable connections are secured.

Interface cables are routed neatly through the cable-management system.

Any empty card slots or power supply bays are filled with card blanks or power supply blanks.

Power supplies are fully inserted in the bays and the captive screws are tightened.

Power supply cables are fully connected to the power supplies and the power source, and secured with appropriate strain relief.

Front covers are installed on the DC-input power supplies.

The air deflector in the lower card cage is down, resting on its stops.

The air filter tray is up and the two captive screws are tightened.

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 Verify that all source voltage circuit breakers supplying power to your system are on.

Step 4 Turn the power switch on each power supply to ON (|). The input OK LED on each DC-input power supply (AC OK LED on each AC-input power supply) should go on.


Note   Turning the power supply switch to ON (|) also engages a latch securing the power supply in place.


Step 5 Listen for the blower modules to power up. The green fans OK LED on the front cover of each blower module should go on.

Step 6 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 12012 Gigaswitch 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 service representative for assistance.
