I/O chassis module slot. They also help to align the module with the

backplane connector.

Each module is slotted at its rear edge. The position of the keying bands

must correspond to these slots to allow insertion of the module. Position

the keying bands on the upper backplane connector between the numbers

at the right of the connectors. Keying bands are only used to key slot 0 of

the module. Figure 3.3 illustrates the encoder module keying positions

for slot 0.
