1200-Watt AC-Input Power Supply
Replacement Instructions
Product Number: PWR-7513-AC(=), PWR-7513-ACU(=), PWR-7513-ACA(=),
PWR-7513-ACI(=), and PWR-7513-ACE(=)
This document contains instructions for installing or replacing a 1200-watt (W), alternating current
(AC)–input power supply in the Cisco 7513.
A single power supply is standard equipment for the Cisco 7513. A second, identical 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 supply, while the remaining supply immediately ramps up to full power
to maintain uninterrupted system operation.

Page 2: Product Overview
Product Overview Product Overview The AC-input power supply is a modular power supply for the Cisco 7513 multiprotocol, multimedia router. The AC-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. - Page 3 12 American Wire Gauge (AWG), 20-amp 1. VAC = volts direct current. 2. The Cisco 7513 requires a minimum of 20-amp service, with a 20-amp receptacle at the power source. The power cable supplied with the Cisco 7513 uses a 20-amp male plug.
- Page 4 Product Overview 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.

Page 6: Environmental Monitoring
Environmental Monitoring and Reporting Functions Environmental Monitoring Three sensors on the Route Switch Processor (RSP2) monitor the temperature of the cooling air that flows through the processor slots: inlet, hotpoint, and exhaust. The sensors are located at the bottom, center, and top of the RSP2, when facing the interface processor end of the chassis and viewing the RSP2 as it is installed. - Page 7 Environmental Monitoring and Reporting Functions Table 2 Typical Processor-Monitored Temperature Thresholds Parameter Normal High Warning High Critical Shutdown Inlet 10–40C – Hotpoint 10–40C – Exhaust 10–40C – – – Processors – – – Power supply – – – Restart – –...
- Page 8 Environmental Monitoring and Reporting Functions The show environment command display reports the current environmental status of the system. The report displays parameters that are out of the normal values. No parameters are displayed if the system status is normal. The example that follows shows the display for a system in which all monitored parameters are within Normal range.
- Page 9 (as “Blower #3” indicates in the following example). The system expects to see three blowers or fans in the Cisco 7513: the main system blower, and one fan in each power supply. The system blower is designated #1, the power supply fan in power bay A is #2, and the power supply fan in power bay B is #3.

Removing and Replacing a Power Supply Removing a Power Supply Follow these steps to remove a power supply. Turn OFF (O) the system power switch on the power supply you plan to remove. Step 1 If possible, turn OFF the circuit breaker to which the system is connected and tape the Step 2 breaker switch in the OFF position. -
Page 14: Replacing A Power Supply
To maintain agency compliance requirements and meet EMI emissions standards in a Caution 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. -
