Introduction Features Diagnostic Controller for Management Each 9C214-2 Power Supply has a diagnostic controller. This diagnostic controller includes a microprocessor that monitors the numerous power supply functions available to the Network Manager via the LCD on the 9C300-1 Environmental Module, as well as local and remote management functions.
Introduction Power Distribution System The SmartSwitch 9000 uses a distributed DC power system (Figure 1-2) similar to those used in super computers. Three separate power buses are used to distribute DC power. The 48 volt DC System Power Bus, located on the backplane, powers all modules and the system cooling fans. The Diagnostic Power Bus provides 5 volts DC to all of the system’s diagnostic controllers and the environmental module. The INB termination power bus provides 3.

Chapter 2 Installing the 9C214-2 Power Supply ! CAUTION This unit to be installed in a restricted access area in accordance with the NEC or the authority having jurisdiction. When installing the unit the following guidelines must be met: • • • • Connect to a 48Vdc SELV source which is reliably connected to earth ground. The branch circuit over current protection must be rated max 30A. Use #10AWG copper conductors only.
Installing the 9C214-2 Power Supply 5. Remove the cover. (Keep the cover in the event you need to remove the power supply. The cover must be replaced to protect the connector.) 6. Hold the power supply by the handles on the top and bottom of the unit, and do the following: a. Align the power supply so that the lip on the bottom and the hook on the top are slightly above the corresponding slots on the chassis. b.

Installing the 9C214-2 Power Supply Connecting Power Source A nominal 48 or 60 volt positive or negative power source can be connected to a 9C214-2 Power Supply. Follow the appropriate steps starting below to make the proper connection.
Installing the 9C214-2 Power Supply Connecting a Nominal -48/-60 Volt Negative Power Source The nominal -48/-60 volt negative power source is connected to a 9C214-2 Power Supply using at least number 10 AWG (5 square millimeters) copper wire to which ring or spade terminals that will accept a number ten screw have been attached. Connect the power source to the connections on the terminal block on the 9C214-2 Power Supply (Figure 2-3) by following the steps below. 1.
Installing the 9C214-2 Power Supply Powering Up a 9C214-2 Power Supply NOTE Before you power up a 9C214-2 Power Supply, make sure that the Environmental Module and all modules have been properly installed. 1. Turn on the 9C214-2 Power Supply using the circuit breaker at the bottom right of the power supply. (The power supply uses a soft start feature and does a pre-power diagnostic check. Outputs become enabled within 5 seconds of power on.) 2. Check to make sure that a. The PWR Status LED is green. b.
Chapter 3 9C214-2 Power Supply Operation The 9C214-2 Power Supply can operate with input voltages ranging from 36 – 72 positive or negative Volts Direct Current (VDC). Each 9C214-2 provides a maximum of 1000 watts of power to the SmartSwitch 9000. When two or more power supplies are installed, the system uses a current sharing scheme where under all load conditions each supply provides power equally.
9C214-2 Power Supply Operation Diagnostic Controller The diagnostic controller is composed of a Z-80 microprocessor and it’s supporting logic. The diagnostic controller is designed to monitor the power supply’s input and output power parameters as well as the temperature and fan status. In addition, the diagnostic controller adjusts fan speed and controls the LANVIEW diagnostic LEDs.
