6 Repeat step 5 for any other shunt that needs to be moved.
Note: For the FR221/V2 only, reinstall the voice/fax daughterboard before replacing the PCB
assembly in the cabinet. Check that none of the long pins are bent or out of alignment.
a. Holding the front corners of the daughterboard, gently ease the RJ-45 jacks into
position at the back panel of the MultiFRAD, then carefully align all the long pins (on
the underside of the daughterboard) with the mating connector on the main PCB
assembly. When you are sure all the long pins are started in the mating connector,
press down on the front edge of the daughterboard until the long pins are secure in
the mating connector.
b. Reinstall the four screws (Figure 2-4) that secure the daughterboard to the standoffs.
7 Align the main PCB assembly with the guide slots on the inside of the chassis and carefully
slide the board back into the chassis.
8 While supporting the back panel, turn the MultiFRAD over again, and replace the two cabinet
mounting screws that were removed in step 2.
9 Turn the MultiFRAD right side up again, then return to Cabling Your MultiFRAD.
