C H A P T E R 1 Introduction The Cisco AC/DC Power System is a rack-mounted, AC-to-DC power system that provides a scalable, compact solution for powering optical platforms at site locations with only AC power available. The system accepts AC inputs and converts them to nominal -48 VDC for DC-powered equipment.
Chapter 1 Introduction 1.1.1 System Shelf 1.1.1 System Shelf The AC/DC power system shelf consists of four rectifier slots and system monitoring/control interfaces. The system controller provides rectifier monitoring, operational data collection, alarm generation, and intra-system communications regulation. Cisco AC/DC Power System (with Optional 1RU DC Distribution Shelf) 124792 Figure 1-1 There are two system shelves, one of which has an LCD display on the front of the shelf.
Chapter 1 Introduction 1.1.2 Rectifier Modules Figure 1-3 shows a front view of the version of the system shelf that does not have an LCD screen.

C H A P T E R 4 System Operation 4.1 System Commissioning The following section should be used to power-up the system for the first time. Step 1 Turn on AC breakers at the AC distribution panel to power up the shelf through the rectifiers. Step 2 The controller and rectifier LEDs will start to blink. It may take a few minutes for the controller to communicate with all rectifiers. Step 3 The system is now commissioned. If the controller RED LED s on, refer to “Chapter 5, “System Troubleshooting.” 4.
Chapter 4 System Operation 4.2.1 Alarm Interface Board and Connections 4.2.1 Alarm Interface Board and Connections The alarm interface board is the main connection point for external communication inputs. The board is located inside the controller and can be accessed by removing the front controller cover and then sliding out the controller tray to expose the alarm connections (located on the right-hand side). Alarm connections are made at the terminal block located on the Alarm/Interface PC board.
Chapter 4 System Operation 4.2.2 Basic Controller Functions Step 3 During this recognition time the controller may report module-related alarms and the red LED on the rectifier may turn on. These alarms are caused by imbalances related to load sharing of the rectifiers (the new rectifier’s output voltage is different than the existing rectifiers). Step 4 The rectifier module will take a few minutes to step up to the correct voltage.
