Installing An Epim - Cabletron Systems ETWMIM User Manual

3. Holding the ETWMIM 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 that both the bottom and
top edges of the card rest in the guide slots. (See Figure 3-2).
4. Slide the ETWMIM into the MMAC until you feel it meet the
backplane. At this 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 use the knurled knobs to draw the
module into the backplane. Forcing a misaligned module into place
can damage the ETWMIM or the MMAC backplane.
6. Turn on the MMAC chassis.
