17.8.2 PROGRAMMABLE JUMPERS
Figures 17-28 through 17-35, and Figures 17-37, 17-39 and 17-41 show the location of all
programmable jumpers in addition to component locations on the Line I/O modules. How to set these
jumpers is described in Table 17-16. Only terminal blocks and RF connectors are accessible with the
Line I/O modules installed in the chassis. All jumpers are accessible only when the modules are
removed from the chassis or are on card extenders.
