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.”
1-2
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).

Fan Speed
Monitoring Functions
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 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 V oltages
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 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.
