    Install Ground Plates on Cabinet 
    Backs
    The ground plate provides the ground connection between cabinets, provides 
    radio frequency (RF) radiation protection, and also stabilizes the cabinets. 
    A ground plate is required between each cabinet (see Figure B-3). Complete the 
    following ste ps to attach the ground plate.
    1. At the back of the c a binets, p ut in all the screws on the upper and lower 
    panels, except for the screws that run along the top and bottom of each 
    cabinet.
    2. At the u p per cabinet, place the top of the ground plate over the bottom of 
    the lower-back  panel. Align the four holes in the ground p late with the four 
    holes at the bottom of the lower back cover of the cabinet and insert the 
    screws. Do not tighten the screws yet.
    3. At the top of the cabinet below the cabinet referred to in Step 2, align the 
    bottom of the ground plate with the to p four holes in the upper back cover 
    of the lower cabinet. Insert the four screws. Do not tighten the screws yet.
    4. Repeat Steps 2 and 3 until the earthquake ground plates are installed 
    between all cabinets.
    5. Tighten all screws.
    Install Front Plates
    For earthquake protection and electromagnetic shielding (as required by CISPR 
    22 regulations), use the front plate instead of the cabinet clip to attach the 
    cabinets to each other. Use one front plate between each cabinet. (Figure B-3). 
    Complete the following steps to install the front plates to the c a binet:
    1. At the front of the c a binets, align the holes in the top of the earthquake 
    front plate with the holes at the b ottom of the up per c abinet, and insert the 
    four screws. Do not tighten the screws yet.
    2. At the front of the c a binets, align the holes in the b ottom of the earthquake 
    front plate with the holes at the top of the lower c abinet, and insert the four 
    #12-24 by 1/2-inch (1.27 cm) thread-forming sc rews. Do not tighten the 
    screws yet.
    3. Repeat Steps 1 and 2 until all the c a binets are fastened together with the 
    earthquake front plate.
    4. Tighten all screws.
