Warning Secure all power cabling when installing this unit to avoid disturbing field-wiring connections. (For translations of this safety warning, refer to the section "Power Cabling Warning" on page page 27.)

Lifting the Chassis Safely

This section is only applicable if you do not have clear access to the power supply bays and must move a rack-mounted chassis. If you do have clear access to the power supply bays, proceed to the next section, "Safety with Electricity."

If space behind a rack-mounted chassis is limited, or if access to the power supply bays is partially blocked by a power strip or other equipment, you may have to slide the chassis partially out of the front of the rack before inserting the power supplies. The minimum requirement is for one person to support the front of the chassis and another person to push it outward from the back and insert the power supply. If you suspect that pushing the chassis out the front of the rack may topple the rack, make sure enough people are available to support the rack while you perform this procedure.

The chassis weighs approximately 120 pounds with 1 power supply and 7 interface processors installed.

Whenever you move or lift the chassis or any heavy object, observe the following guidelines:

• Never move suddenly or twist your body while supporting a heavy object.

Caution To prevent damage, never attempt to lift the chassis with the handles on the power supplies or the interface processors. These handles are not designed to support the weight of the chassis.

• Before sliding a chassis forward in a rack, ensure that doing so will not cause the rack to topple forward. If you suspect it might, obtain additional assistance to help support the rack before moving the chassis.

Safety with Electricity

You can remove or install a redundant (second) power supply without turning off the other supply. Before removing a redundant power supply, ensure that the first supply is powered on to ensure uninterrupted operation.

Follow these basic guidelines when working with any electrical equipment:

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

• Disconnect all power and external cables before moving a chassis.

• Do not work alone if potentially hazardous conditions exist.

• Never assume that power is disconnected from a circuit; always check.

• 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.

In addition, use the guidelines that follow when working with any equipment that is connected to telephone wiring or other network cabling.

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. (For translations of this safety warning, refer to the section "Lightning Activity Warning" on page page 28.)

• 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 is disconnected at the network interface.

• Use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic boards or components are handled improperly, can result in complete or intermittent failures. The processor modules each comprise a printed circuit board that is fixed in a metal carrier. EMI shielding, connectors, and a handle are integral components of the carrier. However, the fan control board is a printed circuit board that is not intended for handling and has no frame or shielding. Handle a processor module or fan tray by the metal frame or carrier only; avoid touching the board (particularly avoid touching any components, traces, or the metal fingers on the edge connector).

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 fan tray, connect the equipment end of a ground strap to an unpainted surface of the chassis, such as a handle on the power supply.

• When removing or installing a power supply, connect the equipment end of a ground strap to the chassis ground screw on the interface processor end of the chassis, or to an unpainted surface inside the noninterface processor end of the chassis, such as the chassis frame.

• Handle printed circuit boards, such as the arbiter, by the edges only; avoid touching the board components, traces, or connector pins.

• Place removed printed circuit boards or components that contain boards on an antistatic surface or in a static shielding bag. Place a removed board component-side-up; place a removed processor module or fan tray board-side-up.

• If you are returning a replaced part to the factory, immediately place it in a static shielding bag to avoid ESD damage to the board.

• Avoid contact between the board and clothing. The wrist strap only protects the board from ESD voltages on the body; ESD voltages on clothing can still cause damage.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohm.

Tools Required

You need the following tools to install or replace a power supply:

• A 1/4-inch flat-blade and Number 2 Phillips screwdriver.

• Small, wire cutter.

• If the chassis is mounted in an equipment rack and cables from other equipment fall in front of the power supply bays, you will need cable ties to temporarily anchor the cables out of the way.

• If access to the power supply bays is partially blocked by a power strip or other permanent rack fixture, you will need a 1/4-inch flat-blade screwdriver to temporarily detach the ears from the equipment rack mounting strips.

• ESD-preventive wrist strap.

Before beginning the power supply installation, check the installation screws on all power supplies and check the area around the power supply bays to determine which tools you will need.

The new or replacement power supply and the power cable that you supply are the only parts you need to complete this installation.

If you remove a power supply and leave the bay empty, install a cover plate over the empty bay. The chassis is shipped with a cover plate installed over the upper bay. If the plate is not available, contact a service representative to order a replacement (Product Number MAS-7KPSCOVER).

Circuit Breaker (30A) Warning

Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 30A U.S. (240 VAC, 20A international) is used on the phase conductors (all current-carrying conductors). (For translations of this safety warning, refer to the section "Circuit Breaker (30A) Warning" on page page 28.)

Installation

The following section describes the procedures for removing an existing power supply and installing a new one. It also contains procedures for installing power supplies in a rack-mounted chassis when the power supply bays are partially blocked.

If cables from other equipment are in front of the bay, move them aside and temporarily secure them with cable ties. If you must remove a rack-mounted chassis from the rack, proceed to the following section, "Removing a Rack-Mounted Chassis." Otherwise, if you now have clear access to the power supply bays, proceed to the section "Removing a Power Supply" to replace an existing supply, or to the section "Inserting a Power Supply" on page 16 to install a new power supply for redundant power.

In systems with redundant power, you can install, remove, or replace one of the power supplies without affecting system operation. When power is removed from one supply, the redundant power feature causes the second supply to ramp up to full power and maintain uninterrupted system operation.

Removing a Rack-Mounted Chassis

This section describes how to proceed if your system is installed in an equipment rack and you do not have clear access to the power supply bays. If the chassis is not in a rack, or if you already have clear access to the power supply bays, you do not need to perform these steps. Proceed to the sections that follow.

If you determine that moving the chassis is unavoidable, you will need to disconnect all power and interface cables. Be sure to label the cables to avoid crossing them when you reconnect them to the chassis. The configuration worksheet provided near the end of this document can help you reconnect the cables to the correct ports if you complete it as you disconnect cables from the interface processors. (For the Cisco 7000, refer to Figure 9, and for the Cisco 7507, refer to Figure 10.)

Caution This procedure might shift the chassis' center of gravity toward the front of the rack and may cause the rack or the chassis to tip. Before performing this procedure, ensure your safety by verifying that you have sufficient assistance to support the rack and the chassis to prevent injury from tipping or falling.

To slide the chassis out of the front of the rack to gain access to the power supply bays, do the following:

Step 2   Before proceeding, ensure that at least one other person is available to support the front of the chassis as you push it out the front of the rack and insert the power supplies.

Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. (For translations of this safety warning, refer to the section "DC Power Disconnection Warning" on page page 29.)

Step 3   Turn all power supplies OFF and disconnect all power and interface cables from the rear of the chassis. Use the configuration worksheet provided at the end of this document to record interface port connections and avoid crossing cables when you reconnect them. (For the Cisco 7000, refer to Figure 9, and for the Cisco 7507, refer to Figure 10.)

Step 4   Use a 1/4-inch flat-blade screwdriver to loosen the four binder-head screws that secure the left and right ears to the front mounting strips on the equipment rack.

Caution To prevent damage, never attempt to lift or support the front of the chassis with the plastic front panels. The panels can break away, which could cause the chassis to drop.

Step 5   Position at least one person in front of the rack to support the front undersides of the chassis and prevent it from falling as you push it forward out of the rack. Grasp the chassis along the metal undersides behind the plastic front panels. If possible, position two people in front of the rack, one person to support each side of the chassis.

Warning The next step shifts the chassis' center of gravity to the front of the rack and may cause the rack or the chassis to tip or fall. Before proceeding, ensure your safety by verifying that you have sufficient assistance to prevent injury due to the rack toppling and/or the chassis falling out of the rack.

Step 6   From the rear of the equipment rack, slowly push the chassis forward out of the rack until there is enough clearance for the power supplies to be inserted into the bay.

Step 7   Proceed to the section "Inserting a Power Supply" on page 16, and follow the steps indicated as quickly and safely as possible.

Step 8   Push the chassis back into the rack until the ears meet the mounting strip on both sides of the equipment rack.

Step 9   Secure each ear to the rack mounting strip with two binder-head screws.

Step 10   Reconnect all interface cables to the ports on the rear of the chassis. If you completed the configuration worksheet before you disconnected the cables, use it as a guideline to reconnect the cables. (For the Cisco 7000, refer to Figure 9, and for the Cisco 7507, refer to Figure 10.)

Step 11   Proceed to the section "Checking the Installation" to apply power and check the installation.

Removing a Power Supply

If you are replacing the power supply in a single-supply system, remove the existing supply from the lower bay first, if possible, and install the new power supply in the lower bay to maintain a low center of gravity in the chassis. (You will have to interrupt system operation to do so.) Always install a filler plate over an empty power supply bay to prevent electrical shock and to protect the backplane connectors from contamination.

Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. (For translations of this safety warning, refer to the section "DC Power Disconnection Warning" on page page 29.)

Following is the procedure for removing a power supply:

Step 2   Use a screwdriver to loosen the captive installation screws on the terminal block cover. (See Figure 5.)

Step 3   Lift and remove the terminal block cover. (See Figure 5.)

Step 4   Use the wire cutter to cut only the nylon ties that secure the cable to the metal bracket. (See Figure 6.)

Warning When installing the unit, the ground connection must always be made first and disconnected last. (For translations of this safety warning, refer to the section "Ground Connection Warning" on page page 30.)

Step 5   Use a screwdriver to remove the three power leads from the terminal block. (See Figure 6.)

Step 6   Use a screwdriver to reinstall the terminal block cover. (The terminal block cover should stay with the power supply.) Do not overtighten the captive installation screws on the terminal block cover. The recommended torque is 8.2 ±0.4 inch-lb.

Step 7   Use a screwdriver to loosen the captive installation screw on the supply. (See Figure 6.)

Step 8   Grasp the power supply handle and pull the supply out of the bay. Place one hand underneath to support the bottom of the supply as you pull it out of the bay. (See Figure 7.)

If the power supply resists when you attempt to pull it out of the bay, the switch is probably not fully in the OFF (O) position, or the captive installation screw at the top of the supply is not fully loosened. Turn the power switch fully counterclockwise to OFF (O), and check the captive installation screw, then try removing the supply again.

Caution To prevent dropping the power supply, use both hands to handle it. The power supply weighs approximately 14 pounds.

Step 9   If the power supply bay is to remain empty, install a cover plate (Product Number MAS-7KBLANK) over the opening and secure the captive mounting screw. If you are installing a replacement power supply, proceed to the section "Inserting a Power Supply." Otherwise, reconnect all power and interface cables on the rear of the chassis and restart the system.

Inserting a Power Supply

Always install the first power supply in the lower power supply bay and the second, if any, in the upper bay. In systems with dual power supplies and when separate power sources are available, connect each power supply to separate input lines so in case of an input line failure, the second source will probably still be available.

Caution If you remove AC-input power supplies from a Cisco 7000 and replace them with DC-input power supplies, you might need to replace the LED board in the Cisco 7000, if the chassis was shipped before November 1, 1994. In this earlier chassis, the LED circuitry will not recognize and indicate the presence of the new DC-input power supplies. If the chassis was shipped after November 1, 1994, no LED board replacement is required. To replace the LED board (Product Number MAS-7000-LED=), refer to the configuration note Cisco 7000 Front Chassis Panel and LED Board Replacement (Document Number 78-1060-01), which ships with the LED board spares or is available on UniverCD.

Following is the procedure for inserting a power supply:

Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. (For translations of this safety warning, refer to the section "DC Power Disconnection Warning" on page page 32.)

Step 2   Check the switch on the face of the power supply, and place it in the OFF (O) position. The interlock tab should not extend out of the unit.

Step 3   Hold the power supply by the handle and place your other hand underneath to support the bottom. (See Figure 7.)

Caution To prevent dropping the power supply and injuring yourself, use both hands to handle it. The power supply weighs approximately 14 pounds.

Step 4   Position the power supply so that it is aligned to go straight into the bay.

Step 5   Push the power supply all the way into the bay. Do not use unnecessary force; firmly push the supply back into the bay until the power supply front panel is flush with the chassis rear panel.

Caution When inserting a power supply into the bay, do not use unnecessary force; slamming the power supply into the bay can damage the connectors on the rear of the supply and inside the chassis. To prevent problems with the Cisco 7000, do not mix DC-input and AC-input power supplies in the same chassis. Your Cisco 7000 must have either DC-input or AC-input power supplies.

Step 6   Using a screwdriver, tighten the captive installation screw on the top of each power supply. (See Figure 8.)

Caution Always tighten the captive installation screw at the top of the power supply before turning on the power switch. This screw prevents the power supply from shifting away from the internal connector and provides proper grounding for the supply. Do not overtighten the terminal block cover captive screws or the terminal block contact screws. The recommended torque is 8.2 ±0.4 inch-lb.

Step 7   Using a screwdriver, loosen the captive installation screws on the terminal block cover, then lift and remove the cover. (See Figure 8.)

Warning When stranded wiring is required, use approved wiring terminations, such as closed-loop or spade-type with upturned lugs. These terminations should be the appropriate size for the wires and should clamp both the insulation and conductor. (For translations of this safety warning, refer to the section "DC Power Supply Warning" on page page 31.)

Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. (For translations of this safety warning, refer to the section "DC Power Disconnection Warning" on page page 32.)

Warning 
The illustration shows the DC power supply terminal block. Wire the DC power supply using the appropriate lugs at the wiring end, as illustrated. The proper wiring sequence is ground to ground, positive to positive (line to L), and negative to negative (neutral to N). Note that the ground wire should always be connected first and disconnected last. (For translations of this safety warning, refer to the section "DC Power Supply Wiring Warning" on page page 33.)

Warning Incorrectly wiring the terminal block could create a dangerous shock hazard and could damage the power supply, power source, and the chassis components.

Step 8   To provide strain relief for the three DC-input cable, attach two nylon ties around the cable and the metal bracket. (See Figure 8.)

Step 9   Install the terminal block cover over the terminal block, and tighten the captive installation screws. (See Figure 8.) Do not overtighten the captive installation screws on the terminal block cover. The recommended torque is 8.2 ±0.4 inch-lb.

Warning To prevent a short-circuit or shock hazard after wiring the DC-input power supply, replace the terminal block cover.

Step 10   Connect the opposite end of the DC-input cable to the DC power source.

Step 11   If you are installing or replacing a second power supply, repeat step 1 through step 11 for the second power supply.

Step 12   Proceed to the following section "Checking the Installation" to apply power and check the installation.

Checking the Installation

To complete the installation turn the power supply on and observe the LEDs on the power supply to verify that the new supply is operating properly using the following steps:

Step 2   Check the following components to make sure they are secure:

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

• All power supply cables are attached to the terminal blocks and secured with nylon ties.

• At the DC power-source end of the power cable, make sure the leads are securely attached to the DC power, and make certain the source power is within the range indicated on the power supply.

• When two supplies are present, make sure the second cable is connected to a separate DC power source if possible.

Warning After wiring the DC power supply, remove the tape from the circuit breaker switch handle and reinstate power by moving the handle of the circuit breaker to the ON position. (For translations of this safety warning, refer to the section "DC Power Connection Warning" on page page 34.)

Step 3   Turn the power supply ON (|) by turning the switch clockwise one-quarter turn.

If the power supply switch resists, the power supply is probably not fully inserted into the bay. Turn the power switch fully counterclockwise to OFF (O), pull the power supply out of the bay about 2 inches, then push the power supply firmly back into the slot. Do not slam the supply into the slot; doing so can damage the connectors on the supply and the backplane. Tighten the captive installation screw before proceeding.

Step 4   Verify that the out fail LED stays off.

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

• If the out fail LED goes on when the power supply is installed in the other bay, 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 two power supplies are installed, and the out fail LED goes on only on one power supply, assume that the power supply or DC source (for that supply) is faulty.

• If the out fail LED lights on two supplies that are connected to the same DC source, suspect that the DC source is faulty, or that an overvoltage or overtemperature condition is causing the power supplies to shut down.

• If the out fail LED lights on two supplies that are connected to separate DC sources, assume that an overvoltage or overtemperature condition is causing the power supplies to shut down.

If the power supply fails (and you need to order a replacement) and you did not record the type of power supply in your chassis, you will have to check the chassis in order to make this determination.

TimeSaver In the Cisco 7000 chassis, with Maintenance Release 9.17(10) and later, the system can identify which type of power supplies are in your chassis: DC-input or AC-input. As a general precaution, use the show environment all command and note the type of power supply indicated in each of your chassis (indicated as either "700W DC" or "700W AC"). Record and save this information in a secure place.

This completes the power supply installation. Refer to the Cisco 7000 Hardware Installation and Maintenance and Cisco 7507 Hardware Installation and Maintenance publications for installation troubleshooting procedures, and to the Router Products Configuration Guide for descriptions and examples of software features and commands. Both of these publications are available on UniverCD or in print.
