4-6 Using the System Controller
POKD FAIL Same as above.
POKE FAIL The System Controller detects a power supply fault. The
condition is logged but no power-off sequence is initiated.
BRD/CHASSIS OVR TEMP The System Controller detects an overtemperature
condition and initiates a power-off sequence.
POWER FAIL WARNING The System Controller detects an AC power failure.
NO SYSTEM CLOCK The System Controller could not detect a system clock on
the midplane, and initiates a power-off sequence.
1.5 V OVER VOLTAGE The System Controller detects a power supply fault and
initiates a power-off sequence. The System Controller does
not turn power on until the operator selects “MENU -
System Log.” This process guards against overvoltage
damage by forcing the operator to examine the System
Event Log.

-5.2 VDC OVER VOLTAGE Same as above.
-12 VDC OVER VOLTAGE Same as above.
48 VDC OVER VOLTAGE Same as above.
1.5 VDC UNDER VOLTAGE The System Controller detects a power supply fault and
initiates the power-off sequence.

-5.2 VDC UNDER VOLTAGE Same as above.
-12 VDC UNDER VOLTAGE Same as above.
48 VDC UNDER VOLTAGE Same as above.
1.5 VDC HIGH WARNING The System Controller detects a voltage out-of-range. The
