The rear of the power bay has eight DC output connectors (see Figure 9-2). A power cord
connects one output connector to a Cx-brick, R-brick, or I/O brick. This connection
provides 12-VDC standby power, 48-VDC power, and monitoring signals.
Note: The L1 controller of a connecting module can monitor the status and enable the
output ports of the power bay.
The power bay module also has six AC input connectors, one for each power supply
location. For example, when the power bay contains four power supplies, connectors 3,
4, 5, and 6 (the four connectors on the left) connect to the power distribution unit (PDU).
When the power bay contains six power supplies, connectors 1 and 2 also connect to the
PDU.
The reset button resets the power bay when a fault condition occurs.
