Chapter 9 Connecting Digital Modem Network Modules Adding 6-Port MICA Modules to a Digital Modem Network Module Installing 6-Port MICA Modules To install new or replacement MICA modules, follow these steps: Step 1 Orient the digital modem network module so that the faceplate is on the right. Caution Handle MICA modules by the card edges only. MICA modules are ESD-sensitive components and can be damaged by mishandling. Step 2 Step 3 Step 4 Step 5 Hold the MICA module with the connector edge at the bottom and the polarization notch at the right. Tilting the MICA module toward you at about a 45-degree angle, insert it into a socket, beginning with the empty socket closest to you. (See Figure 9-7.) Rock it downward, using the minimum amount of force required. (See Figure 9-8.) When the MICA module is properly seated, the socket guide posts fit through the alignment holes, and the spring clips click into place. Ensure that the MICA module is straight and that the alignment holes line up with the plastic guides on the socket. It is normal to feel some resistance, but do not use excessive force on the MICA module, and do not touch the surface components. Repeat Step 2 through Step 4 for any additional MICA modules.
