CONFIGURATION AND INSTALLATION

INSTALLING THE FDCMIM
The FDCMIM has “hot swap” capabilities. This means you can insert
and remove the module without first turning off the MMAC.
Occasionally, depending on the MMAC configuration, other MIMs in
the hub may go into a reset condition when you hot swap an FDCMIM.
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 MMAC 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 a misaligned module
into place can damage the FDCMIM or the MMAC backplane.
