007-4498-002
The power bay module has eight output connectors (refer to Figure A-17). A power cord
connects one output connector to a DC-powered NUMAlink module, PCI expansion
module, or L2 controller. This connection provides 12 Vdc standby, 48 Vdc, 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 two power supplies, connectors 5
and 6 connect to the power distribution unit (PDU). When the power bay contains three
power supplies, connector 4 also connects to the PDU.
