Always handle the EME by the front panel only.
■
Do not touch the components, pins, leads, or
solder connections.
■
When you insert the EME into the module guides,
do not twist or otherwise force the module into
the chassis.
■
Before you push the module into the chassis, make
sure that the module ejector handles are open.
■
When you slide the module into place, match the
left and right module guides.
