Chapter 2 Installing the 9C300-1 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 MMAC-Plus 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.
Installing the 9C300-1 Environmental Module If the MMAC-Plus chassis has not been powered up, make sure that all modules have been properly installed; then power up the MMAC-Plus chassis by following the steps in the MMAC-Plus Installation Guide.

Chapter 3 9C300-1 Environmental Module Operation The 9C300-1 Environmental Module, as shown in Figure 3-1, performs three main functions. It monitors several chassis environmental parameters, provides multiple out-of-band management interfaces, as well as system cooling. The Environmental Module also includes LANVIEW® LEDs for at-a-glance diagnostics. MMAC EPIM STATUS ALARM 9C300-1 1 2 3 4 5 6 7 ENT ER COM 1 COM 2 8 9 10 11 12 13 14 Figure 3-1.
9C300-1 Environmental Module Operation External Ambient Temperature The 9C300-1 Environmental Module includes an external ambient temperature sensor. This sensor is located on the front of the Environmental Module, as shown in 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.
Monitoring Functions 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 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.
9C300-1 Environmental Module Operation System Humidity The 9C300-1 Environmental Module monitors the non-condensing humidity level of the MMAC-Plus. The results of the monitoring are available to the network manager via LCD, as well as local and remote management. The humidity levels are displayed as shown in Table 3-2. Table 3-2.
Monitoring Functions LANVIEW LEDs The LANVIEW LEDs on the front of the 9C300-1 Environmental Module may be used as an aid in troubleshooting. There are two LEDs visible to the user (Figure 3-4): the STATUS LED and the ALARM LED.

9C300-1 Environmental Module Operation The ALARM LED indicates the presence, or absence, of an unread system alarm(s). Unread system alarms can be read using the LCD and five-function keypad. The possible states and descriptions of the ALARM LED are listed in Table 3-5. Table 3-5. ALARM LED LED Color State Description Green Functional No unread alarms. Yellow Functional Pending unread system alarms, warning. Red Functional Pending unread system alarms, critical.
Out-of-Band Management COM1 and COM2 Ports The 9C300-1 Environmental Module front panel has two RJ-45 communication ports for RS-232 serial communication to and from the MMAC-Plus. Figure 3-5 illustrates a single RJ-45 communication port connector. COM1 and COM2 can be configured to run the Serial Line Internet Protocol (SLIP), Point-to-Point Protocol (PPP), Local Management via a terminal or modem connection, or monitor an American Power Conversion Smart UPS.
9C300-1 Environmental Module Operation The Ethernet™ Port Interface Module (EPIM) The 9C300-1 Environmental Module provides a port for Cabletron Systems EPIMs. The EPIM provides a direct connection to the internal SMB-10 bus. This connection can be used for out-of-band graphical SNMP management of the MMAC-Plus system or a Telnet session into local management. Any standard Cabletron EPIM can be installed. Refer to Appendix A for detailed information on the EPIM.
