19" Frame Metal Back Installation Combinations
The 19" frame metal back can be ordered with a variety of frames, modules, and accessories
(e.g. battery, radio, accessory box.) In certain cases, choosing a certain accessory reduces the
other options. For example, the portable radio is installed on the 19" frame metal back with the
No I/O Frame in place of one accessory box. Likewise a battery is installed on the 19" frame
metal back with the No I/O Frame in place of one accessory box.
For diagrams of the various combinations, see Figure 2-28 below.
