1200-Watt DC-Input Power Supply Replacement Instructions

In systems with redundant power, the power supplies are load-sharing and fully hot-swappable; you can remove and replace one supply, while the remaining supply immediately ramps up to full power to maintain uninterrupted system operation.

The sections in this document include the following:

Product Overview

The DC-input power supply is a modular power supply for the Cisco 7513 multiprotocol, multimedia router. The DC-input power supply is optional equipment in the Cisco 7513. A second, identical power supply, if installed, provides redundant power. Power supplies reside in power supply bays in the rear of the router chassis, as shown in Figure 1.

Figure 1 Cisco 7513---Rear-Panel View

Caution To prevent problems with the Cisco 7513, do not mix DC-input and AC-input power supplies in the same chassis. Your Cisco 7513 must have either DC-input or AC-input power supplies.

The power A bay contains the first (or standard) power supply, and the power B bay contains the second (optional) supply in systems with redundant power.

Dual power supplies are automatically load-sharing and redundant, which means that you can install or replace a second power supply on line. During normal operation, dual supplies provide system power simultaneously (load share). When you remove one supply, the remaining supply immediately ramps up to provide full power and maintain uninterrupted power to the system. Whenever possible, connect each power supply to a separate DC source.

DC-Input Power Supply LED Indications and the Safety Interlock Mechanism

On the Cisco 7513 chassis front panel, the power A and power B LEDs go on when the power supply in the corresponding bay is installed and supplying power to the system. Both the power LEDs should be on in systems with redundant power.

The power supply LEDs include the DC OK LED, the fan OK LED, and the output fail LED. (See Figure 2.) The DC OK LED is on when the input power is applied. The fan OK LED is normally on; however, it is off if the power supply fan fails. The output fail LED is normally off, but flashes at power on for a lamp test.

Figure 2 Power Supply LEDs

The output fail LED lights for either of the following reasons:

Power supply DC-output failure, which could be caused by overload by the system or an actual failure in the DC-input power.
Power shutdown, initiated by the power supply because it detected an out-of-tolerance voltage condition in the power supply

In systems with a single power supply, and in systems with redundant power when both power supplies are shutting down, the output fail LED lights momentarily as the system ramps down, but goes out when the power supply has completely shut down.

The power supplies feature the following three safety interlock features:

An on/off switch with a locking mechanism (see Figure 3) on each power supply prevents the power supply from being removed from the chassis when the power supply switch is in the ON (|) position. When the switch is ON, a metal tab extends into a slot in the chassis. When the switch is OFF (O), the tab is raised and clears the slot.

Figure 3 On/off Switch Locking Mechanism

A captive installation screw at the bottom of the power supply front panel provides electrical grounding and prevents the power supply from vibrating or sliding out of the bay and dislodging from the power connectors in the backplane. (See Figure 2.)

The power supplies are self-monitoring. Each supply monitors its own temperature and internal voltages. An internal fan in each power supply draws cooling air from the back of the chassis, through the power supply, and out the front of the chassis. The power supply airflow is separate from that of the rest of the chassis.

Installation Safety, ESD Precautions, and Tools Required

Before you begin this installation, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment. This section also provides power requirements to consider if you are adding a second power supply to your system for redundant power, and lists of the tools and parts you need to perform this installation.

Safety Guidelines

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

Warning Two people are required to lift the chassis. Grasp the chassis underneath the lower edge and lift with both hands. To prevent injury, keep your back straight and lift with your legs, not your back. To prevent damage to the chassis and components, never attempt to lift the chassis with the handles on the power supplies or on the interface processors, or by the plastic panels on the front of the chassis. These handles were not designed to support the weight of the chassis. (To see translated versions of this warning, refer to page 15.)

Always disconnect all power cords and interface cables before moving the chassis.
Keep tools and chassis 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

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 Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. (To see translated versions of this warning, refer to page 16.)

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.

Warning Warning Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages. (To see translated versions of this warning, refer to page 17.)

Circuit Protection Requirements

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, 50A U.S. (240 VAC, 30A international) is used on the phase conductors (all current-carrying conductors). (To see translated versions of this warning, refer to page 17.)

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.

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 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.
If you plan to return a replaced part to the factory, immediately place it in a static shielding bag to avoid ESD damage to the board.
The wrist strap only protects the board from ESD voltages on the body; ESD voltages on clothing can still cause damage.

Note Periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms.

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.
Appropriate length and diameter of conduit through which the DC-input cable will pass. The opening on the terminal block cover is one inch in diameter. Installation of this conduit depends on your site and is beyond the scope of this publication.
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 empty bay.

Removing and Replacing a Power Supply

The power supplies rest on the floor of the chassis under the card cage.

The following sections describe the procedures for removing an existing power supply and installing a new one. The power supplies rest on the floor of the chassis under the card cage. The DC-input cable must be routed through conduit from your power source to the power supply.

Note You provide conduit through which you must route the DC-input power cable. If cables from other equipment are in front of the bay, move them aside and temporarily secure them with cable ties. You must disconnect the conduit from the conduit bracket before you can remove a power supply from the chassis. Router and attach the conduit to make each power supply accessible for replacement and maintenance.

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.

Note This procedure is not for new system installation; perform this procedure only if you have already connected the system to network interfaces and performed the first-time startup procedures described in the Cisco 7513 Hardware Installation and Maintenance publication.

Warning Although it is not necessary to turn OFF both power supplies to remove one of two power supplies, you must turn OFF the power to the power supply you plan to remove. When the power is on with one of two power supplies removed, high current is exposed on the power connector inside the chassis. If you have only one power supply, you must turn OFF the power to this power supply.

Removing a Power Supply

Follow these steps to remove a power supply.

Step 1 Turn OFF (O) the system power switch on the power supply you are going to remove.

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. (To see translated versions of this warning, refer to page 20.)

Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units or disconnect the power at the circuit breaker on DC units. (To see translated versions of this warning, refer to page 18.)

Warning This unit might have more than one power cord. To reduce the risk of electric shock, disconnect the two power supply cords before servicing the unit. (To see translated versions of this warning, refer to page 19.)

Step 2 Remove the 8-mm screws on the terminal block cover so the cover is free of the terminal block. (See Figure 4.)

Warning When installing the unit, the ground connection must always be made first and disconnected last. (To see translated versions of this warning, refer to page 20.)

Figure 4 Removing and Replacing the Terminal Block Cover

Step 3 Replace the terminal block cover so it remains with the power supply.

Step 4 Use the large slotted screwdriver to loosen the captive screw that secures the power supply to the chassis frame. (See Figure 5.)

Figure 5 Removing a Power Supply

Step 5 Grasp the power supply handle and pull the power supply approximately halfway out of the bay. Then with your other hand under the power supply, pull it completely out of the bay. (See Figure 6.)

Figure 6 Supporting the Power Supply

Caution To maintain agency compliance requirements and meet EMI emissions standards in Cisco 7513 chassis with a single power supply, the power supply blank must remain in the power supply bay adjacent to the power supply. (See Figure 7.) Do not remove this blank from the chassis unless you do so to install a redundant power supply. To prevent system problems, do not mix AC-input and DC-input power supplies in the same chassis.

Figure 7 Power Supply Blank

Replacing a Power Supply

Follow these steps to replace the power supply:

Step 1 Hold the power supply as shown in Figure 6 and slide it into the power supply bay. Push the supply all the way into the chassis until the sides are flush against the chassis frame. To prevent damaging the backplane connector, do not jam the power supply into the bay.

Step 2 Use the slotted screwdriver to tighten the captive screw that secures the power supply to the chassis frame. (See Figure 5.)

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. (To see translated versions of this warning, refer to page 23.)

Step 3 If not already done, route the DC-input power cable through the conduit from your power source, through the conduit bracket on the power supply (see Figure 8), and make a sufficient length of wire available to attach to the three terminal block connections.

Step 4 Attach and tighten the conduit to the conduit bracket. How this conduit is attached depends on your site; its attachment is beyond the scope of this documentation.

Step 5 Use the 8-mm nut driver and attach the ground wire to the ground terminal. (See Figure 8.)

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. (To see translated versions of this warning, refer to page 21.)

Step 6 Check the power supply's wiring and color code to verify that it matches the wiring and color code at the DC source.

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

Step 7 Replace the terminal block cover. (Refer to Figure 4 on page 9.)

Step 8 After the DC power cable leads are reconnected, reconnect the power cable at the power source.

Step 9 If you are replacing both power supplies, repeat Steps 1 through 5 for the second power supply.

Figure 8 Removing and Replacing the DC-Input Power Cable

Note When you turn ON power to the new power supply, the DC OK LED and the fan OK LED will go on and stay on. No other LEDs should go on

This completes the power supply replacement procedure.

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

Checking the Installation

To complete the installation, turn on the power supply and observe the LEDs on the power supply to verify that the new supply is operating properly.

Step 1 Review the descriptions of the power supply LEDs on page 4.

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.
At the DC power-source end of the power cable, the leads are securely attached to the DC power, the source power is within the range indicated on the power supply.
When two supplies are present, 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. (to see trans.ated versions of this warning, refer to page 23.)

Step 3 Turn the power supply ON (|) by turning the switch clockwise one-quarter turn. The DC OK LED and the fan OK LED will go on and stay on. No other LEDs should go on.

If the power supply switch resists, it 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 two 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 output fail LED stays off.

If the output 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 output 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 output fail LED goes on only on one power supply, assume that the power supply or DC source (for that supply) is faulty.
If the output 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 output 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 to operate properly after several attempts to initialize it, contact a service representative for assistance. 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 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 "1200W DC" or "1200W AC"). Record and save this information in a secure place.

This completes the power supply installation. Refer to the Cisco 7513 Hardware Installation and Maintenance publication for installation troubleshooting procedures, and to the Router Products Command Reference publication for descriptions and examples of software features and commands.
