Product Overview

The Cisco 12012 has two card cages; the upper card cage and the lower card cage. (Refer to .) 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 with AC-Input Power Supplies

The lower card cage, located behind the air filter, has five horizontal slots for switch fabric cards.

Below the lower card cage is a power supply bay. Up to four AC-input power supplies or two DC-input power supplies can be installed in the bay.

The AC-input power supply is a modular power supply for the Cisco 12012. The Cisco 12012 supports up to four AC-input power supplies in a power supply bay located below the lower card cage. (Refer to .) The power supply bay is divided into four positions designated A1, A2, B1, and B2 (from left to right). Cisco 12012 systems come standard with two AC-input power supplies installed in power supply bay positions A1 and B1. You can install a third and fourth AC-input power supply in power supply bay positions A2 and B2 for power supply redundancy and current sharing. Unoccupied power supply bay positions must have power supply blanks installed to maintain the airflow and for EMI considerations.

The Cisco 12012 supports online insertion and removal of redundant power supplies, which means you can remove and replace an AC-input power supply in systems equipped with three or four AC-input power supplies. In systems with only two power supplies, you must power down the system before you replace an AC-input power supply.


Warning   

AC operation requires a minimum configuration of two AC-input power supplies


The AC-input power supply is a modular unit measuring 3.8 inches (9.6 cm) wide by 10 inches (25.4 cm) high by 15 inches (38 cm) deep and weighs 18 lb (8 kg). (Refer to .) The power supply slides in and out of the power supply bay and is secured in place by a combination of a single captive screw on the power supply faceplate and a latch that is part of the power switch also located on the power supply faceplate.

Electrical connections between the power supply and the Cisco 12012 backplane are made through a connector located at the back of the power supply.


Caution   
Do not mix AC-input and DC-input power supplies in the same Cisco 12012. This configuration is not supported and can cause system damage.

AC-Input Power Supply LEDs

The faceplate of the AC-input power supply has two LEDs: a green AC OK LED and a red output fail LED. (Refer to .) These LEDs indicate the following:

AC OK LED—When the power switch is turned on, this green LED should go on immediately, indicating that the source AC voltage is within the operational range of 180 to 264 VAC. If the power switch is on and the LED remains off, the source voltage is not within the operational range.

Output fail LED—If this red LED is on, one or both of the power supply output voltages (+5 and -48 VDC) is out of tolerance. When you first turn on the power supply, the output fail LED blinks on and off for five seconds, then turns off. If the LED stays on, a fault has been detected within the power supply.

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, route processor (RP), switch fabric cards, alarm card, 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 install or replace an AC-input power supply:

1/4-inch flat-blade screwdriver

ESD-preventive wrist strap

The AC-input power supply (Product Number: PWR-GSR12-AC=). You can use the power cord from the removed power supply for the replacement power supply.


Note   If you are upgrading your system with an additional AC -input power supply, make sure that you ordered the correct AC power cord for your location and that it was shipped with your order. Refer to for AC power cord product numbers.


Removing and Replacing an AC-Input Power Supply

This section provides two procedures that describe how to remove and how to replace an AC-input power supply in the Cisco 12012. If you are upgrading your system with additional power supplies, go to the section "Replacing or Adding a Power Supply."


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

Removing a Power Supply

To remove an AC-input power supply, perform the following steps:


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 If you have not already done so, turn the power supply power switch to the STANDBY position on the power supply you want to remove. (Refer to a.)


Note   Turning the power supply switch to the STANDBY position also releases a latch that secures the power supply in the power supply bay.


Step 3 Release the spring clip on the power supply faceplate. (Refer to b.)

Step 4 Disconnect the AC power cord from the power supply AC receptacle. (Refer to c.)

Step 5 Disconnect the AC power cord from the source AC receptacle. (Refer to d.)

Step 6 Loosen the captive screw on the power supply faceplate. (Refer to e.)

Figure 5 Disconnecting an AC-Input Power Supply

Step 7 Grasp the power supply handle and pull straight out to disconnect the power supply from the backplane connector. Slide the power supply halfway out of the bay. (Refer to .)

Figure 6 Removing an AC-Input Power Supply


Caution   
The AC-input power supply weighs 18 lb (8 kg). Use two hands when handling the power supply.

Step 8 Place your free hand underneath the power supply for support and slide the power supply completely out of the bay.

If you plan to return the old power supply to the factory, repackage it in the shipping container you received with the replacement power supply.

Replacing or Adding a Power Supply

If you are upgrading your system by installing additional power supplies, you can install the power supply without removing power from the system.


Note   We recommend attaching each AC-input power supply to an independent power source for full redundancy. We also recommend that your Cisco 12012 use an uninterruptable power source (UPS) to protect against power failures at your site. Each AC-input power supply operating between 200 VAC and 240 VAC requires a dedicated 20-amp service for North America (10-amp or 16-amp service for International).



Caution   
Do not mix AC-input and DC-input power supplies in a Cisco 12012.


Caution   
The AC-input power supply weighs 18 lb (8 kg). Use two hands when handling the power supply.

Perform the following steps to install a new or replacement 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 replacement supply is in the STANDBY position. (Refer to .)

Step 3 If you are upgrading your Cisco 12012 with an additional AC-input power supply, you must remove the power supply blank covering the empty power supply bay position before installing the power supply. To remove a power supply blank:

(a) Loosen the captive screw on the power supply blank faceplate.

(b) Slide the power supply blank out of the power supply bay.

(c) Retain the power supply blank for possible future use.


Caution   
To prevent damaging the power supply backplane connector, do not use excessive force when installing a power supply into the power supply 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 bay position that is empty must have a power supply blank installed to maintain airflow and for EMI considerations.


Step 4 Using two hands to support and guide the power supply, slide it into the vacant bay position. (Refer to .) Push the power supply all the way into the 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.


Figure 7 Installing an AC-Input Power Supply

Step 5 Tighten the captive screw on the power supply faceplate. (Refer to a.)

Step 6 Connect the AC power cord to the power supply AC receptacle. (Refer to b.)

Step 7 Attach the spring clip over the power cord plug. (Refer to c.)

Step 8 Connect the other end of the AC power cord to the source AC receptacle. (Refer to d.)

Step 9 Turn the power supply power switch to ON (|). (Refer to e.)


Note   Turning the power supply switch to ON (|) also engages a latch that secures the power supply in the power supply bay.


Figure 8 Connecting an AC-Input Power Supply

Step 10 Verify that any empty power supply bay positions have power supply blanks installed.

This completes the AC-input power supply replacement procedure.

Proceed to the following section, "Checking the Installation," to verify the installation.

Checking the Installation

To complete the installation, observe the LEDs on the faceplate to verify that the power supply is operating properly, then perform the following steps:


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

Each power supply is inserted all the way into its bay, and the captive screw is tightened.

All power supply cords are attached to the power supply receptacles and secured with spring clips.

At the AC power-source end of the power cord, the cord is securely attached to the AC power connector.

The source AC voltage is within the range indicated on the power supply faceplate.

When two or more supplies are installed, each power cord is connected to a separate AC power source if possible. Each AC power source must be on a dedicated circuit rated at 20 amps, North America; 10 or 16 amps, International.

All unused power supply bay positions must have power supply blanks installed to maintain proper airflow and for EMI considerations.

Step 2 Verify that the Cisco 12012 powers up correctly. Visually check that the green AC OK LED on the power supply faceplate is on. This indicates that the source AC voltage is within the range of 180 to 264 VAC.

If the AC OK LED is off, check for the following:

Verify that the source AC circuit breaker is on.

Verify that the AC power cord is firmly connected from the source AC receptacle to the power supply.

Check that the power supply power switch in the ON (|) position.

Step 3 Visually check that the red output fail LED flashes on and off for five seconds, then goes off.

If the output fail LED goes on, move the power supply to another bay if possible and turn the power switch ON (|). If the LEDs go on properly when the power supply is installed in the other bay, suspect a faulty backplane connector.

If the output fail LED goes on when the power supply is installed in the other bay position, suspect a power supply failure or an adverse environmental condition (the power supply has detected an overvoltage or overtemperature condition and has shut down).

If the output fail LED goes on only on one power supply, assume that the power supply or AC source (for that power supply) is faulty.

If the output fail LED lights on multiple power supplies connected to separate AC sources, suspect that an overcurrent or possibly an overtemperature condition has occurred in the power supply bay causing the power supplies to fail.

If the power supply fails to operate properly after several attempts to power it up, contact a service representative for assistance.
