3. A reset condition can cause a momentary but self correcting interruption in network service Hot swapping does not damage any Cabletron Systems module However we recommend turning off the MMAC when inserting or removing any MIM If you cannot turn off the MMAC hot swapping modules is acceptable Note Observe all static precautions when handling FDCMIM boards After choosing an appropriate MMAC slot use the following instructions to install the FDCMIM 1 Turn off the power to the MMAC Remember that MMACs with multiple power supplies have an On Off switch for each supply 2 Remove the FDCMIM from its protective cover Always leave the FDCMIM inside the protective cover when it is not installed in an MMAC If you need to set the MIM down for a moment during installation set it on a clean non conductive surface 3 Holding the FDCMIM by the front panel or by the edges of the circuit board align the bottom and top edges of the card with the slot guides in the MMAC chassis Be sure both the bottom and top edges of the card rest in the guide slots See Figure 2 6 4 Slide the FDCMIM into the until you feel it meet the backplane At his point the front panel should be about 1 2 inch from being flush with the rest of the modules in the MMAC 5 Press gently to seat the module into the backplane Do not try to force the module into place or attempt to use the knurled nuts to draw the module into the backplane Forcing
