Installing the WM-4T1i Module
Installing the WM-4T1i Module
All Alpine ™ 3800 series switch module cards (SMMi modules and I/O modules) are
hot-swappable. You do not need to power off the system to remove or insert a module
card.
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:
1 Prior 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 top-right corner of the Alpine
front panel.
2 Loosen the module card by unscrewing the screws using a #2 Phillips-head
screwdriver.
3 Rotate 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.
4 Slide the module card out of the chassis.
5 Slide 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.
6 To 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
Phillips-head screwdriver.
