Assertion Levels

A C M
LARM ONTROLLER ANAGEMENT
When a fault condition occurs on the fan unit or power supply, a signal is
sent to TAC indicating a fault condition. The signal that the fan unit or
power supply sends may use one of the following assertion levels:
Active-High — Signal indicates the assertion state as a logic ONE state.
Active-Low — Signal indicates the assertion state as a logic ZERO state.
The power supply and fan unit assertion levels are configured for the
following parameters (see Table 8-2). Assertion levels are normally set to
active-low, unless otherwise specified by the auxiliary device vendor. The
default is set to active-low.
