DECbridge 500/600 Series Problem Solving
All DECbridge 500/600 series units contain four logic modules:
•
AP or AP2 (Application Processor) module
•
NI or NI(3) (Network Interface) module
•
FI (Fiber Interface) module with various types of interfaces
•
QM (Queue Manager) module
Table 1–2 shows the four logic modules contained in each bridge model.
NOTE
In this manual, the terms AP and NI are used as general
references to the Application Processor and Network
Interface modules. The terms AP2 and NI(3) are used
only when referring specifically to those two modules.
