To properly insert a module, ensure that the correct module type is inserted into the correct slot position. The ejector/
inserter clips located at the top and at the bottom of each module must be in the disengaged position as the module is
smoothly inserted into the slot. Once the clips have cleared the raised edge of the chassis, engage the clips simultaneously.
When the clips have locked into position, the module will be fully inserted.
CPU connections must be individually disconnected from the module before the module can be removed from the
chassis.
The new CT/VT modules can only be used with new CPUs; similarly, old CT/VT modules can only be used with old
CPUs. In the event that there is a mismatch between the CPU and CT/VT module, the relay does not function and
a
DSP ERROR or HARDWARE MISMATCH error displays.
