AMBIENT OVER TEMP

The incoming ambient air temperature is too high to provide proper system cooling.

BLOWER FAILURE

The system blower fan has failed.

BLOWER RPM LOW

The System Controller has stepped up the blower speed to compensate for a low RPM reading.

BLOWER RPM HIGH

The blower is running faster than expected. The system is not shut down.

BLOWER RPM FAILURE

The blower RPM is below tolerance after being stepped up to full speed.

BOOT ERROR

A system processor failed to respond to the System Controller during boot arbitration.

BRD/CHASSIS OVER TEMP

A detector in the cardcage or chassis sensed a temperature over the allowed limit.

CPU NOT RESPONDING

The CPU system master is not responding to requests transmitted over the serial link.

FP BUTTON STUCK

The System Controller has detected a front panel button that has been pressed for more than 30 seconds. The System Controller cannot function properly under this condition.

NO SYSTEM CLOCK

The system backplane clock has failed.

POKA FAIL

Power ok A (POKA); a voltage source supporting the Power Enable A signal failed.

POKB FAIL

Power ok B (POKB); a voltage source supporting the Power Enable B signal failed.

POKC FAIL

Power ok C (POKC); a voltage source supporting the Power Enable C signal failed.

POKD FAIL

Power ok D (POKD); a voltage source supporting the Power Enable D signal failed.

POKE FAIL

Power ok E (POKE); a voltage source supporting the Power Enable E signal failed. The system will not power off because of this condition.

POWER FAIL WARNING

The off-line switcher has detected an AC power loss.

NMI

A non-maskable interrupt (NMI) was entered onto the system backplane from a front panel menu option in the System Controller.

SCLR DETECTED

The System Controller detected an SCLR on the system backplane. This reset was initiated from the System Controller front panel by an operator.

SYSTEM OFF

The key switch was turned to the Off position and the System Controller powered off the system.

SYSTEM ON

The System Controller has successfully powered on the system.

SYSTEM RESET

The System Controller detected an SCLR and initiated a system boot arbitration process. SCLR can be generated by any processor board or by the System Controller.

BAD ALARM TYPE

The firmware attempted to send an invalid alarm to the CPU.

BAD MSG: CPU PROCESS

The CPU or System Controller process has received an invalid message.

BAD MSG: DISPLAY

The display process has received an invalid message.

BAD MSG: POK CHK

The power ok check process received an invalid message.

BAD MSG: SEQUENCER

The sequencer process has received an invalid message.

BAD MSG: SYS MON

The system monitor process has received an invalid message.

BAD WARNING/ALARM

The routine that decodes alarm and warning messages detected an invalid message.

BAD WARNING TYPE

The firmware attempted to send an invalid warning to the CPU.

COP FAILURE

The Computer Operating Properly (COP) timer has exceeded time limits. The System Controller firmware must write to a COP timer port before it times out. If the firmware exceeds the time allowed between writes to a COP port, an interrupt is generated. The System Controller firmware may have entered an endless loop.

COP MONITOR FAILURE

A Computer Operating Properly (COP) clock monitor failure was detected. The System Controller clock oscillator is operating at less than 10 KHz.

DEBUG SWITCH ERROR

The System Controller detected data corruption in the nonvolatile RAM debug switch location.

An error was detected in the front panel LCD screen control process.

FP READ FAULT

A read of the front panel status register did not complete successfully.

FREE MSG NODE ERROR

The free message node queue has overflowed.

FREE TCB NODE ERROR

The free timer control block queue has overflowed.

ILLEGAL OPCODE TRAP

The System Controller's microprocessor tried to execute an illegal instruction. Probably because of a stack overrun followed by a process switch.

PULSE ACCU INPUT

An interrupt was detected on the pulse accumulator input port. The port is not used and an interrupt is treated as an error.

PULSE ACCU OVERFLOW

The pulse accumulator overflow port received an interrupt. This port is not used and the interrupt is treated as an error.

SPI TRANSFER

An interrupt was detected on the synchronous serial peripheral interface. This interface is not supported and the interrupt is treated as an error.

STACK FAULT PID 0–6

One of the seven stack areas used by a System Controller process has overflowed its assigned boundaries.

The System Controller detected an invalid measurement from the temperature sensor.

TIMER IN COMP 1

The timer input compare port received an interrupt. The port is not used and the interrupt is treated as an error.

One of the five timer output compare ports received an interrupt. The port is not supported and the interrupt is treated as an error.

XMITTER 1 TIMEOUT

The System Controller's 1st UART experienced a failure.

XMITTER 2 TIMEOUT

The System Controller's 2nd UART experienced a failure.
