Chapter 2 Installing the SSU-2000e
Installing the SDU-2000e
Installing SDU Modules
The SDU-2000e shelf has 12 plug-in module slots located on the front of the
chassis. The module slots are numbered from left to right looking at the front of the
shelf, A1 through A12. Each module slot has a specific address defined in Table
2-10 below. Each module slot has two hybrid DIN connectors associated with it on
the backplane. The hybrid contacts of these connectors are used for power, logic
ground, and frame ground connections. Each module slot has three pins connected
together on each hybrid DIN connector which are used to detect module removal.
Use the precautions in Handling Modules, on page 73, when handling modules in
the SDU-2000e. Install modules in the SDU-2000e using the procedures in
Installing a Module, on page 75.
