Word / Acronym Definition
ACA Australian Communication Authority
ANSI American National Standards Institute
ATX Advanced Technology Extended
Auto-Ranging Power supply that automatically senses and adjust itself to the proper input voltage range (110
VAC or 220 VAC). No manual switches or manual adjustments are needed.
BMC Baseboard Management Controller
CFM Cubic Feet per Minute (airflow)
CMOS Complementary Metal Oxide Silicon
Dropout A condition that allows the line voltage input to the power supply to drop to below the minimum
operating voltage.
EEB Entry E-Bay
EMP Emergency Management Port
FP Front Panel
FRB Fault Resilient Booting
FRU Field Replaceable Unit
HSBP Hot Swap Backplane
Latch Off A power supply, after detecting a fault condition, shuts itself off. Even if the fault condition
disappears the supply does not restart unless manual or electronic intervention occurs. Manual
intervention commonly includes briefly removing and then reconnecting the supply, or it could be
done through a switch. Electronic intervention could be done by electronic signals in the Server
System.
LCD Liquid Crystal Display
LCP Local Control Panel
LPC Low-Pin Count
Monotonically A waveform changes from one level to another in a steady fashion, without intermediate
retrenchment or oscillation.
MTBF Mean Time Between Failure
MTTR Mean Time to Repair
Noise The periodic or random signals over frequency band of 10 Hz to 20 MHz.
OTP Over Temperature Protection
Over-current A condition in which a supply attempts to provide more output current than the amount for which
it is rated. This commonly occurs if there is a ‘short circuit’ condition in the load attached to the
supply.
OVP Over Voltage Protection
PDB Power Distribution Board
PFC Power Factor Correction
PSU Power Supply Unit
PWOK A typical logic level output signal provided by the supply that signals the Server System that all
DC output voltages are within their specified range
RI Ring Indicate
Ripple The periodic or random signals over frequency band of 10 Hz to 20 MHz.
Rise Time Rise time is defined as the time it takes any output voltage to rise from 10% to 95% of its
nominal voltage.
Sag The condition where the AC line voltage drops below the nominal voltage conditions
SCA Single Connector Attachment
