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).
