SMMi LEDs
Table 9-1 describes the LED activity on the SMMi.
Installing SMMi Modules
To install the SMMi:
1 Attach the ESD strap that is provided to your wrist and connect the metal end to the
ground receptacle that is located on the top-right corner of the switch front panel.
2 Ensure that the SMMi is oriented correctly (printed circuit board (PCB) on top) and
that the ejector/injector handles are open, as shown in Figure 9-3.

3 Slide the SMMi into the appropriate slot of the chassis, until it is fully seated in the
backplane.
Caution: You can install the SMMi only in the top slot of the Alpine 3808 or 3804
chassis. The SMMi does not fit in any other chassis slots. Forceful insertion can
damage the module.
