2. Place the module in the plastic tracks on the top and bottom of the slot that
guides the module into position.
3. Do not force the module into its backplane connector. Apply firm even
pressure on the module to seat it properly.
4. Snap the chassis latch over the top of the module to secure it.
5. Connect the wiring arm to the module.
The front panel of the input module contains a green RUN and a red FLT (fault)
indicator (Figure 3.4). At power–up, the green and red indicators are on. An
initial module self–check occurs. If there is no fault, the red indicator turns off.
The green indicator will blink until the processor completes a successful write
block transfer to the module. If a fault is found initially or occurs later, the red
FLT indicator lights. Possible module fault causes and corrective action are
discussed in Chapter 8, Troubleshooting.
