Figure 1-14. Keyplate/LRU Relationship
Some G900X/G950 LRU racks employ a keyplate/hex-dowel system that mates with the back of certain
units and their rear plates. This prevents another similarly sized unit from being inserted into the
incorrect rack and potentially damaging the connectors. Each keyplate is paired with an opposite mating
plate as shown in Figure 1-14 and Table 1-14.
