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. Control of the fans’ operating speed is  
also provided for 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 MMAC-Plus via a Local  
Management (LM) connection or an SNMP-based management application which  
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.  
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).

Monitoring Functions  
Fan Speed  
The 9C300-1 Environmental Module adjusts the speed of the system cooling fans  
ambient temperature rises 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 MMAC-Plus system to accommodate  
changing operating environments.  
To prolong fan life and limit audible noise when full fan speed is not necessary  
for cooling.

System Voltages  
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.

From 3.1 volts to 5 volts  
From 11 volts to 13 volts  
Internal Operating Temperature  
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.

Transmitter Power decreases as temperatures rise and increases as  
temperatures fall. Use the Output Power Coefficient to calculate increased or  
decreased power output for your operating environment. For example, the  
typical power output at 25°C is -16.4 dBm. For a 4°C temperature increase,  
multiply the typical coefficient (-0.15 dBm) by four and add the result to typical  
output power (4 x -0.15 dBm + -16.4 = -17.0).

The transmitter power levels given above are Peak Power Levels after optical  
overshoot. You must use a Peak Power Meter to correctly compare the values  
given above to those measured on any particular port. If you are measuring  
power levels with an Average Power Meter, add 3 dBm to the average power  
measurement to correctly compare the average power values measured to the  
values listed above (i.e., -33.5 dBm average + 3 dB = -30.5 dBm peak).

Connector Type  
This connector type is a BNC receptacle, with gold center contact, for use with  
BNC type tee-connectors and RG-58 thin-net cable.  
Grounding  
For safety reasons, only one end of a thin-net segment should be connected to  
earth ground. Connection to earth ground at more than one point on the segment  
may cause dangerous ground currents.  
The BNC port of the Coaxial Interface Modules is not connected to earth ground.
