Standard (4 + 1) Power Configuration

The black power cord at the upper right corner of the
subsystem is used only for the standard (4 + 1)
configuration. It is not used for the redundant (4 + 4)
configuration.
This standard power configuration (Figure 1-15) is the minimum configuration Compaq
recommends. If a power supply SBB fails you might be able to replace it before a second
fails. The standard power configuration has the following components:
•
5 – power supply SBBs
•
1 – ac power entry controller
Any one of the following errors will cause the subsystem to cease operation:
•
Failure of two power supply SBBs
•
Failure of the ac power entry controller
•
Failure of the ac power source
•
Failure of the PDU (ESA12000 only)
