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.
