2-8 Theory of Operation
Status LEOs
Four LEOs are contained on the service panel to indicate power supply status. In addition, thirteen
LEOs on the top of the power supply can be accessed for additional information if desired. Specific
reasons for power supply assembly failure are indicated by the
LEOs.
The four service panel LEOs that indicate power supply status are defined as follows:
POWER ON - green; indicates that + 5V supply is enabled, that no failures have been detected,
and that the supervisor board is enabled and capable of detecting faults and
shutting down the power supply assembly.
PS - red; indicates that power is applied to the assembly and + 16V bias voltage is
available from the primary board, but + 5V supply is disabled; an open door or
overtemperature condition does not light this LED.
TEMP - red; indicates that processor stack temperature has exceeded 1 aaoc.
DOOR - red; indicates that 110 card cage door or processor stack door is open.
The thirteen LEOs on the top of the power supply assembly are labeled and defined as follows:
DOORS OPEN - same indication as DOOR LED on service panel. OV also lights.
STACK TEMP - same indication as TEMP LED on service panel.
SEC
BOARD - indicates that the temperature in the power supply assembly has exceeded
97°C, or the + 12V MM power supply has failed.
PWR - indicates that peak primary current exceeded 9A.
OV - used in conjuction with voltage LEOs described below; "on" indicates an
overvoltage condition on one or more of the supplies or door open, "off"
indicates an undervoltage condition.
-19 - indicates a fault condition on the applicable supply. If the OV LED is also lit, an
- 12 overvoltage condition is indicated. If the OV LED is not lit, an undervoltage
- 2 condition
is indicated.
