This document contains instructions for installing or replacing a 1200-watt (W), AC-input power

supply in the Cisco 7513 and Cisco 7576 routers.

Note If you are upgrading a Cisco 7513 to a Cisco 7576, use this document as a reference for

transferring power supplies from the Cisco 7513 to the Cisco 7576.

A single power supply is standard equipment in the Cisco 7513. A dual power supply is standard

equipment in the Cisco 7576. A second power supply, when installed, provides redundant power.

In systems with redundant power, the power supplies are load sharing and fully hot swappable. You

can remove and replace one power supply while the remaining supply immediately powers up to

provide full power and to maintain uninterrupted system operation.

Product Overview Product Overview The AC-input power supply is a modular power supply for the Cisco 7513 and Cisco 7576 multiprotocol, multimedia routers. A second power supply, if installed, provides redundant power. Power supplies reside in power supply bays (labeled Power A and Power B) in the rear of the router chassis, as shown in Figure 1. Note The Cisco 7513 and Cisco 7576 use the same chassis and power supplies.
PAGE 3
AC-Input Power Supply Specifications Power bay A contains the first (or standard) power supply, and power bay B contains the second (optional) supply in systems with redundant power. Table 1 lists the AC-input power supply specifications. Note The Cisco 7576 features two routers on one backplane. These are identified as router A and router B. These designations have no relationship to the power bays, which are identified as power A and power B.

Product Overview Figure 2 20-Amp AC Power Cable Connector and Plug and 20-Amp Receptacle LED Indications and the Safety Interlock Mechanism On the Cisco 7513 and Cisco 7576 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. LED Indications The power supply LEDs include the AC OK LED, the FAN OK LED, and the OUTPUT FAIL LED. (See Figure 3.
PAGE 5
Environmental Monitoring and Reporting Functions 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 powers down, but goes out when the power supply has completely shut down.
PAGE 6
Environmental Monitoring and Reporting Functions The reporting functions periodically log the values of measured parameters so that you can retrieve them for analysis later, and the reporting functions display warnings on the console if any of the monitored parameters exceed defined thresholds. In addition to monitoring internal temperature and voltage levels, the system also monitors the blower. If the blower fails, the system displays a warning message on the console.
PAGE 7
Environmental Monitoring — Power supply detected an overvoltage, overcurrent, AC or DC undervoltage, or overtemperature condition within the power supply. This includes operator shutdown by turning off the system power switch, which the power supply interprets as an undervoltage condition. — The chassis interface detected an overtemperature condition within the system. • Blower failure—The blower impeller has stopped turning.
PAGE 8
Installation Safety, ESD Precautions, and Tools Required The power supplies monitor internal power supply temperature and voltages. A power supply is either within tolerance (Normal) or out of tolerance (Critical or Warning levels), as shown in Table 3. If an internal power supply temperature or voltage reaches a critical level, the power supply shuts down without any interaction with the system processor.

Safety Guidelines Warnung Dieses Warnsymbol bedeutet Gefahr. Sie befinden sich in einer Situation, die zu einer Körperverletzung führen könnte. Bevor Sie mit der Arbeit an irgendeinem Gerät beginnen, seien Sie sich der mit elektrischen Stromkreisen verbundenen Gefahren und der Standardpraktiken zur Vermeidung von Unfällen bewußt.

Installation Safety, ESD Precautions, and Tools Required • 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.
PAGE 11
Tools Required • The wrist strap only protects the board from ESD voltages on the body; ESD voltages on clothing can still cause damage. Warning For safety, 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 screwdriver and a number 2 phillips screwdriver.
PAGE 12
Removing and Replacing a Power Supply 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 7500 Series Installation and Configuration Guide. 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.
PAGE 13
Replacing a Power Supply Figure 6 Supporting the Power Supply Caution To maintain agency compliance requirements and meet EMI emissions standards in a Cisco 7513 or Cisco 7576 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 need to install a redundant power supply. To prevent system problems, do not mix AC-input and DC-input power supplies in the same chassis.
PAGE 14
Checking the Installation Step 5 If you are replacing both power supplies, repeat Steps 1 through 4 for the second power supply. This completes the power supply replacement procedure. Proceed to the “Checking the Installation” that follows to apply power and check the installation. Checking the Installation To complete the installation, turn the power supply on and observe the LEDs to verify that the power supply is operating properly.
PAGE 15
Checking the Installation • If the OUTPUT FAIL LED lights on two supplies that are connected to separate AC 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.
