Chapter 4 System Support
The systems covered in this guide utilize the following specialized functions built into the
LPC47B367 I/O Controller:
♦ Power/HD LED status indicators – The I/O controller provides color and blink control for the
front panel LEDs used for indicating system events as listed below. Indications valid for both
D315 and d325 unless otherwise indicated.
System Status
S0: System on (normal operation)
S1: Suspend
S3: Suspend to RAM
S4: Suspend to disk
S5: Soft off
Processor not seated
ROM flashing
No memory installed
Power supply crowbar activated (D315
only)
CPU thermal shutdown
Memory error (d325 only)
Video error (d325 only)
System board failure (d325 only)
Invalid ROM checksum (d325 only)
System off
NOTES:
[1] Red during flash, then blinks green @ 1 Hz when user can reboot.
[2] Repetitive sequence of 2 red blinks @ 1 Hz, followed by 2-second pause.
[3] Repetitive sequence of four red blinks @ 1 Hz followed by 2-second pause
[4] Repetitive sequence of five red blinks @ 1 Hz followed by 2-second pause.
[5] Repetitive sequence of six red blinks @ 1 Hz followed by 2-second pause.
[6] Repetitive sequence of seven red blinks @ 1 Hz followed by 2-second pause.
[7] Repetitive sequence of eight red blinks @ 1 Hz followed by 2-second pause.
♦
I/O security – The parallel, serial, and diskette interfaces may be disabled individually by
software and the LPC47B367's disabling register locked. If the disabling register is locked, a
system reset through a cold boot is required to gain access to the disabling (Device Disable)
register.
♦
Legacy/ACPI power button mode control – The LPC47B367 receives the pulse signal from
the system's power button and produces the PS On signal according to the mode (legacy or
ACPI) selected. Refer to chapter 7 for more information regarding power management.
