Introduction
UsingThis Manual
Read through this manual to become familiar with its contents and to gain an
understanding of the features and capabilities of the Environmental Module prior
to installing and operating it.

Introduction, provides product descriptions and features, gives a brief
description of the 9C300-1 Environmental Module and ends with a list of related
manuals.
Chapter 2
Installing the 9C300-1 Environmental Module, contains detailed
information for unpacking and installing the Environmental Module.
Chapter 3

information about the Environmental Module operation.
Chapter 4

Environmental Module.
Appendix A
EPIM Specifications , contains detailed information about the
various EPIMs that can be used with the 9C300-1 Environmental Module.
Appendix B
Uninterruptible Power Supply (UPS) , contains detailed information
about connecting, configuring, and monitoring a UPS.
The 9C300-1 Environmental Module
The 9C300-1 Environmental Module, shown in Figure 1-1, provides system
cooling, out-of band management capabilities, and environmental/power
monitoring for the SmartSwitch 9000 System. The Environmental Module is
inserted in the slot above the module card cage in the front of the SmartSwitch
9000 chassis.

Introduction

Figure 1-1. The 9C300-1 Environmental Module
Features
System Cooling
The 9C300-1 Environmental Module houses the cooling fan subsystem. There are
four, high-air flow fans in the assembly to provide necessary chassis cooling. Any
one of these can fail without adversely affecting system operation. The fans’
operation and speed are continuously monitored, allowing network technicians
to be quickly notified if repairs are needed. The fans’ operating speed is also
controlled, to provide maximum cooling efficiency and fan life. The fans are
protected from controller failure by a fail-safe circuit. In the event of a controller
malfunction, this circuit forces the fan subsystem to maximum speed and notifies
Network Management.
Out-of-Band Management
Out-of-band management refers to managing the SmartSwitch 9000 via a Local
Management (LM) connection or an SNMP-based management application that
does not use the same network connection to the chassis as “user data.”
Four Out-of-band management interfaces are built into the 9C300-1
Environmental Module. One channel is the 4x40 character backlit LCD and
associated five-button keypad. This interface provides a network manager or
technician with the capability to review system status, performance and
configuration information. Two interfaces are serial RS-232 ports. These ports
support local management via a VT100 session, SLIP, or PPP, or monitor an
American Power Conversion Smart UPS.

1-3
Introduction
The remaining out-of-band management interface supports any standard
Cabletron Ethernet Port Interface Module (EPIM). This interface provides a direct
connection to the internal System Management Bus-10 (SMB-10).
Environmental/Power Monitoring
The 9C300-1 Environmental Module monitors and reports chassis power
parameters, ambient chassis temperature, chassis humidity, temperature of the
Environmental Module itself, as well as the status and speed of the chassis
cooling fans.
Flash EEPROM
The capability of downloading future firmware upgrades has been built into the
9C300-1 Environmental Module.
Hot Swapping
The 9C300-1 Environmental Module can be removed from the chassis while the
SmartSwitch 9000 is running without interrupting network performance.
LANVIEW
®
LEDs
Two LEDs, STATUS and ALARM, are built into the front of the 9C300-1
Environmental Module. These LEDs indicate the status of the Environmental
Module and the presence or absence of system alarms.

Environmental Module
Installing the 9C300-1 Environmental Module
The 9C300-1 Environmental Module is installed in the slot above the module card
cage in the front of the SmartSwitch 9000 chassis, as shown in Figure 2-1.
Install an Environmental Module by following the steps below:
1. Unpack the Environmental Module 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 Environmental Module must be reshipped.)
2. Remove it from the protective plastic bag. Observe all precautions to prevent
damage from Electrostatic Discharge (ESD). (Save the bag in the event the
Environmental Module must be reshipped.)
3. Remove the plastic protective cap that covers the connector on the rear of the
Environmental Module.
4. Examine it carefully, checking for damage. If any damage exists, DO NOT
install it. Immediately contact Cabletron Systems Technical Support.
5. Hold the left and right sides.
6. Line up the rails on the left and right sides with the tracks on the left and right
inside panels of the chassis.
7. Slide the Environmental Module into the chassis until it is completely seated.
If the SmartSwitch 9000 chassis has been powered up, the 9C300-1 Environmental
Module illuminates the STATUS and ALARM LEDs and displays the name
Cabletron on the LCD.

If the LEDs are any color other than green, refer to LANVIEW LEDs in Chapter 3.
If no keypad entries are made within 60 seconds, the LCD scrolls through various
non-interactive mode screens.
If the SmartSwitch 9000 chassis has not been powered up, make sure that all
modules have been properly installed; then, power up the SmartSwitch 9000
chassis by following the steps in the
SmartSwitch 9000 Installation Guide .

Operation
The 9C300-1 Environmental Module, Figure 3-1, performs three main functions. It
monitors several chassis environmental parameters, provides multiple out-of-
band management interfaces, and cools the system. The Environmental Module
also includes LANVIEW
®
LEDs for at-a-glance diagnostics.

Monitoring Functions
The 9C300-1 Environmental Module monitors the following SmartSwitch 9000
functions:
• External ambient temperature
• Fan speed
• System humidity
• System voltages
• Internal operating temperature
External AmbientTemperature
The 9C300-1 Environmental Module includes an external ambient temperature
sensor. This sensor is located on the front of the Environmental Module,
Figure 3-2. The ambient temperature is monitored and the results of the
monitoring are available to the network manager via the LCD, as well as local and
remote management.

9C300-1 Environmental Module Operation
Table 3-1 lists the ambient temperature information available to the network
manager.
Fan Speed
The 9C300-1 Environmental Module adjusts the speed of the system cooling fans
(Figure 3-3) based on the external ambient temperature. Fan speed increases as
ambient temperature increases to ensure adequate cooling for the system.
Conversely, fan speed decreases as ambient temperature decreases. In the event
the ambient temperature sensor, or the Environmental Module itself, fails, fan
speed defaults to maximum speed to ensure adequate cooling.
The ability to control fan speed is useful for two reasons:
• To increase the cooling level of the SmartSwitch 9000 system to accommodate
changing operating environments.
• To prolong fan life and limit audible noise when full fan speed is not necessary
for cooling.

of the SmartSwitch 9000. The results of the monitoring are available to the
network manager via LCD, as well as local and remote management. Table 3-2

SystemVoltages
The 9C300-1 Environmental Module monitors specific system power parameters
to ensure that they are within acceptable limits. The power parameters monitored
from the backplane are the 48 volt DC System Power Bus and the INB
Termination Power Bus. The power parameter monitored within the
Environmental Module is the 12 volt internal line. The results of the monitoring
are available to the network manager via LCD, as well as local and remote
management. Voltages above or below the acceptable voltage limits cause an
alarm to be sent to the network manager. Table 3-3 summarizes these acceptable
voltage limits.
Internal OperatingTemperature
The 9C300-1 Environmental Module monitors its own internal operating
temperature by comparing its current temperature to the ambient temperature
and programmed rise temperatures to determine current temperature status. If
the temperature of the Environmental Module exceeds normal operating limits,
an alarm is sent to the network manager. In addition, if the ambient temperature
sensor fails, pre-established temperature ranges have been programmed to ensure
proper internal temperature monitoring.
