Diagnostic Controller for Management

Introduction

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.

Internal Temperature Sensor

Each 9C214-2 Power Supply has its own built-in temperature sensor for
monitoring and reporting its own internal temperature to the Network Manager
via LCD, as well as local and remote management.

Cooling Fan

Each 9C214-2 Power Supply has its own cooling fan. The microprocessor within
the diagnostic controller increases or decreases the fan speed based on the
temperature of the power supply. In the event of microprocessor failure, fan
speed defaults to 100% to ensure protection of the power supply.

Thermal Overload Protection

Each 9C214-2 Power Supply includes a thermal shutdown circuit. This circuit
protects the power supply from overheating by shutting the power supply down
if a thermal overload occurs. Automatic recovery takes place after the thermal
overload condition is corrected.

Load Sharing

Each 9C214-2 Power Supply uses a current sharing design. This design allows
multiple power supplies to equally (within ± 5%) share the output load. For
example, if two power supplies are used, each power supply provides 50% ± 5%
of the output load. This feature increases the life of each power supply.

Input Polarity Detection

The 9C214-2 Power Supply is equipped with an input polarity detection feature.
In the event that input to the terminal block is reversed, a buzzer within the
power supply sounds.

Hot Swapping

A 9C214-2 Power Supply can be installed or r emoved from the back of the chassis
while another power supply is operating without affecting network operation.
However, before removing a power supply make sure the switch is turned off.

LANVIEW

®

LEDs

Each 9C214-2 Power Supply has three LANVIEW LEDS: the PWR Status LED
indicates the status of the 9C214-2 input and all outputs, the SMB Status LED
indicates the status of the diagnostic controller, and the Power Supply Level
Indicator LED indicates the percentage of the power supply’s capacity being
used.

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 3.3 volts DC to the
SmartSwitch 9000 9C614 INB termination modules.

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.

Each 9C214-2 Power Supply converts the 36 – 72 VDC to three different DC
outputs for use by the power buses within the SmartSwitch 9000. Each of these
outputs is described below.

• 57 volts are supplied to the 48 volt DC System Power Bus for use throughout

the chassis for each installed module and the Environmental Module system
fans.

• 5 volts are supplied to the Diagnostic Power Bus used by the diagnostic

controllers and the Environmental Module.

• 3.3 volts are supplied to the INB Termination Power Bus.

Operating Functions

The 9C214-2 Power Supply includes the following functions:

• System Diagnostic Controller

• Temperature Sensor

• Power Supply Cooling

• LANVIEW LEDs

• Load Sharing

3-1

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. The information gathered by the diagnostic
controller is available to the network manager via the LCD on the 9C300-1
Environmental Module, as well as local and remote management. If the
diagnostic controller fails, the 9C214-2 Power Supply has been designed to
continue to function and supply power to the system.

Internal T emperature Sensor

Each 9C214-2 Power Supply has a built-in temperature sensor for monitoring its
own internal temperature. The results of the monitoring are available to the
network manager via the LCD on the 9C300-1 Environmental Module, as well as
local and remote management.

Power Supply Cooling

Each 9C214-2 Power Supply includes an internal cooling fan. The diagnostic
controller monitors the internal temperature of the power supply and increases or
decreases the fan speed based on that temperature. If the diagnostic controller
fails, fan speed defaults to 100% to ensure protection of the power supply.

LANVIEW LEDs

The LANVIEW LEDs on the back of the 9C214-2 Power Supply can be used as an
aid in troubleshooting.

There are three LANVIEW LEDs visible to the user (Figure 3-1):
