Removing a Module

Each module is locked to the main board with a single standoff and is connected to the main board by two connectors. The pins within the connectors are compressed to the corresponding board pin receptacles by a metal compression bar which, when secured with screws, compresses the module connector pins to the board receptacle pins (Figure 3-6).
