Introduction
1.2.4 Switch Control Processor
The i960 switch control processor provides the distributed connection
1.2.5 9A000 and SFCS Series Network Modules
The network modules for the 9A000 and SFCS series act as the physical input/output ports to the 9A000 and SFCS series switch. A network module may have up to six physical ports, depending on its physical configuration.
There is also a logical control port located inside the SCP which is referred to in the switch software as the Control Port (CTL). This control port is a logical (not physical) location where cells that are directed to the SCP itself are sent. (See section 1.4.1 for more information.)
1.2.6 Environmental Information
In the 9A000 and SFCS series, there is a temperature sensor, located over the switch fabric area of the enclosure, which ensures that the internal cabinet temperature is not too high. This temperature is displayed on the Environ- mental Module LCD readout, within the MMAC Plus chassis. The power uti- lization for the 9A000 and SFCS series is also monitored and can be displayed on the Environmental Module.
