Configured bay control
connectors in configured
output bay
Each configured bay control connector in the configured
input bay connects to a configured bay control connector in
the configured output bay. The connection hardware for each
of these connections is a bundle of 16 AWG control cables,
with connectors on both ends. See Configured Bay Control
Connection Hardware on page 88.
