Introduction

1.2.4 Switch Control Processor

The i960 switch control processor provides the distributed connection set-up for a network of ATM switches. The switch control processor primarily pro- vides management access through SNMP and is responsible for storing and updating all SNMP management information. Additionally, the switch con- trol processor can access the ATM switch in-band in very much the same manner as an ATM adapter in a workstation (such as the Fore SBA-200 SBus Adapter). Since it has the ability to communicate over IP, the 9A000 and SFCS series can route IP traffic from one given IP network to another. The switch control processor, and associated software, manages the behavior of the 9A000 and SFCS series switch board (i.e., connection setup), but is not involved in the actual cell switching.

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.
