Caution: Service to Alpine modules should be performed by trained service personnel only. Before installing or removing any components of the system, or before carrying out any maintenance procedures, read the safety information provided in Appendix A of the Alpine Hardware Installation Guide.
Warning: You must install blank panels in empty slots to ensure adequate system cooling.
To remove and replace a module card, follow these steps:
1Prior to removing/installing a module card into the Alpine 3804 or Alpine 3808 chassis, put on the ESD wrist strap that is provided with the chassis, and connect the metal end to the ground receptacle located on the
2Loosen the module card by unscrewing the screws using a #2
3Rotate the ejector/injector handles to disengage the module card from the backplane.
Note: Blank panels do not have ejector/injector handles, because they do not engage the backplane. They are secured entirely by the retaining screws. In addition, the retaining screws are not captive.
4Slide the module card out of the chassis.
5Slide the new module card into the appropriate slot of the chassis (SMMi modules into the orange slot, I/O modules into Slots 1 through 4 on the Alpine 3804, or Slots 1 through 8 on the Alpine 3808), until it is fully seated in the backplane.
Caution: Ensure that the sheet metal of the module, and not the PCB board, engages the card cage runners.
As the module begins to seat in the chassis, the ejector/injector handles will begin to close.
6To secure the module in the chassis, close the ejector/injector handles by pushing them toward the center of the module card, and tighten the screws using a #2
