Chapter 2: INSTALLING THE CSMIM-T1
1. Remove Security Bars from MMAC chassis, and blank plates from
desired slots.
2. Holding the CSMIM-T1 by the front panel, or by the edges of the
board, align the bottom and top edges of the board with the guide slots.
Make sure that both of the edges of the card rest in the guide slots.
3. Slide the CSMIM-T1 (Figure 2-2) into the desired MMAC slots.
4. Firmly press the module connections 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 CSMIM-T1 or the MMAC backplane.
5. Secure the module to the MMAC chassis by tightening the knurled
knobs. If you do not tighten the knurled knobs, vibration can cause the
module to lose contact with the backplane and disrupt your network.
6. Replace Security Bars on MMAC chassis.
7. Power-up the MMAC.
