The 9C214-3 Power Supply

The 9C214-3 power supply, shown in Figure 1-1, is a 2000 watt, triple output
supply that provides power to the SmartSwitch 9000 chassis. At least one power
supply must be installed; however, additional power supplies can be installed to
achieve redundancy. 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.

Features

Diagnostic Controller for Management

Introduction

Each 9C214-3 power supply has a diagnostic controller which includes a
microprocessor that monitors the numerous power supply functions available to
the Network Manager via LCD, as well as local and remote management.

Internal Temperature Sensor

Each 9C214-3 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

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

A thermal shutdown circuit is included within each 9C214-3 power supply. This
circuit protects the power supply from overheating if a thermal overload occurs.
Automatic recovery takes place after the thermal overload condition is corrected.

Load Sharing

Each 9C214-3 power supply uses a current sharing scheme whereby if two power
supplies are used, under all load conditions, each supply provides 50% (± 5%) of
the required load on each output. This feature incr eases the life of a power supply.

Universal AC Input

The 9C214-3 power supply accepts AC input voltage ranging from 207–264 volts
at 50/60Hz.

Hot Swapping

9C214-3 power supplies can be installed or removed from the back of the chassis
while another power supply is operating without affecting network operation.

LANVIEW

®

LEDs

Each 9C214-3 power supply has three LANVIEW LEDS: the PWR Status LED
indicates the status of the 9C214-3 power output, 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 load being used.

Introduction

Power Distribution System

The SmartSwitch 9000 uses a distributed DC power distribution 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 INB termination modules (ITM).

To offer the greatest variety of power options, the 48-volt DC System Power Bus
and all components that use this bus are capable of operating using voltage
ranging from 40–60 volts DC. This capability allows the SmartSwitch 9000 to
operate from typical AC power and to char ge batteries in a battery backup unit or
operate on DC power , such as found in a central of fice or a battery backup system.

Chapter 2

Installing the 9C214-3 Power Supply

At least one power supply must be installed on the rear of the SmartSwitch 9000
chassis. Additional power supplies can be added to achieve redundancy.

A power supply is installed by plugging it into either the left or right power
supply connector on the SmartSwitch 9000 chassis, as shown in Figure 2-1.

Unpacking the 9C214-3 Power Supply

1. Unpack the power supply by removing it from the shipping box and sliding
the two foam end caps off the unit. (Save the shipping box and packing
materials in the event the power supply must be reshipped.)

2. Remove the power supply from the protective plastic bag. (Save the bag in the
event the power supply must be reshipped.)

3. Examine the power supply carefully, checking for damage. If any damage
exists, DO NOT install the power supply. Immediately contact the Cabletron
Systems Global Technical Assistance Center.

Installing to the SmartSwitch 9000 Chassis

1. Loosen and remove the two screws from one of the power supply connector
covers on the rear of the SmartSwitch 9000 chassis.

2. Remove the cover . (Keep the cover in the event you need to r emove the power
supply. The cover must be replaced to protect the connector.)

2-1

Installing the 9C214-3 Power Supply

3. 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. Ease the power supply down until the hook catches the slot on the top and

the tab is inserted in the slot on the bottom.

c. Plug the power supply in the connector on the back of the chassis by

pushing the power supply in until its frame touches the surface of the
SmartSwitch 9000 chassis. Do not force the power supply in place. If
significant resistance is encountered before the frame is flush with the
chassis, remove the power supply, realign it, and push it in again.

d. Secure the power supply to the chassis by tightening the two screws on

the top and two screws on the bottom of the power supply. For proper
chassis grounding, the four screws must be properly tightened.

Powering Up the 9C214-3 Power Supply

Before you turn the power switch on, make sure that the Environmental Module and all

NOTE

Interface Modules have been properly installed.

The 9C214-3 Power Supply is powered up by following the steps below:

1. Plug one end of the power cord (supplied with the power supply) into the AC

power socket on the lower right front corner of the power supply.

2. Plug the other end of the power cord into an AC r eceptacle. Turn on the power

supply using the switch located near the power socket.

3. The power supply uses a soft start feature and does a pre-power diagnostic

check. Outputs become enabled within 5 seconds of turning the power on.

4. Check to make sure that

a. The PWR Status LED is green.
b. The SMB Status LED is green.

If the LEDs are any color other than green, refer to

LANVIEW LEDs in Chapter 3.

9C214-3 Power Supply Operation

The 9C214-3 power supply can operate with input voltages ranging from
207–264 VAC at 50/60 Hz. Each 9C214-3 provides a maximum of 2000 watts of
power to the SmartSwitch 9000.

When two power supplies are installed, the system uses a current sharing scheme
where, under all load conditions, each supply provides 50% (± 5%) of the requir ed
load.

Each 9C214-3 power supply converts the 207–264 VAC to three different DC
outputs for internal use by the system. Each of these outputs is described below.

• 56 volts 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 supplied to the Diagnostic Power Bus used by the diagnostic controllers

and the Environmental Module.

• 3.3 volts supplied to the INB Termination Power Bus.

Operating Functions

The 9C214-3 power supply includes the following functions:

• System Diagnostic Controller

• Internal Temperature Sensor

• Power Supply Cooling

3-1

9C214-3 Power Supply Operation

System Diagnostic Controller

The System Diagnostic Controller is composed of a Z-80 microprocessor and its
supporting logic. The System Diagnostic Controller monitors the power supply’s
input and output power parameters as well as the temperature and fan status. In
addition, the System Diagnostic Controller adjusts fan speed and controls the
LANVIEW diagnostic LEDs. The information gathered by the System Diagnostic
Controller is available to the network manager via the LCD, as well as via local
and remote management. If the System Diagnostic Controller fails, the 9C214-3
power supply has been designed to continue to function and supply power to the
system.

Internal T emperature Sensor

Each 9C214-3 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 LCD, as well as local and remote management.

Power Supply Cooling

Each 9C214-3 power supply includes an internal cooling fan. The System
Diagnostic Controller monitors the internal temperature of the power supply and
increases or decreases the fan speed based on that temperature. If the System
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 9C214-3 power supply may be used as an
aid for troubleshooting.

There are three LANVIEW LEDs visible to the user (Figure 3-1): the PWR Status
LED, the SMB Status LED, and the Power Supply Level Indicator LED.
